Health Advantages of Mediterranean Diets

Health & Nutrition, , , , , , , ,

Although the cases of heart disease in the United States were staggering during the early 1960s, heart disease rates from people in Greece were some of the lowest in the world.
But what was most remarkable about this fact was that they were enjoying this excellent health, although their diet contained nearly 40% of its calories of fat. In addition, they had one or two glasses of wine with their meal.

Scientists discovered while searching along the Mediterranean Sea that not only the Greece people enjoyed a long life, but also neighboring countries, like France, Italy and Spain.

Christopher Gardner, PhD, assistant professor of medicine at the Stanford Prevention research Center in Stanford, California stated:
“For one thing, the traditional Mediterranean diet includes a lot of
vegetables and legumes, along with fruits, fresh whole-grain breads, dates and nuts.
Meats like lamb and chicken were consumed sometimes and in small portions, and the main source of fat in their diet is monounsaturated fat from olives and olive oil, rather than the saturated fats from animal food. In addition, physical activity plays a big part in their daily routine”, he adds.

But how healthy is the traditional Mediterranean diet ? you may ask.
In one study, French researchers looked at 600 men who recently had a heart attack. They gave half of the men a traditional Mediterranean diet and half of them a low-fat, low cholesterol diet that was usually advised to people with heart disease to follow. Those who followed the traditional Mediterranean diet had a 70% lower rate off recurring heart problems than those who followed the prudent low-fat diet.

Similar results were found with other studies. After examining the diets and disease rates of people in seven different countries, researchers found that, taking in account the 46% of death rates of middle- aged men in America, only 4% of men on Creta, had similar problems. In fact, the death rate from all causes on Creta during this 15 year study was lower than that of the other countries.

Researchers in 2006 reviewed 35 experimental studies of the Mediterranean diet and found that the diet had a positive effect on cholesterol and insulin resistance. They also found that the diet lowers the risk of metabolic syndrome, heart attack and heart disease. And also the risk of cancer in obese patients who have had a heart attack.

The Fat Factor
Olive oil is the most important factor in the Mediterranean diet.
The total fat intake is 25% to 35% of total calories. Although people in Mediterranean countries eat as much fat as we do (or more), they eat relatively little meat. They eat red meat only a few times a month, but fish and poultry are eaten every week.

As a result they consume only very small amounts of artery-clogging saturated fat. “The big difference comes from limiting saturated fat and replacing it with monounsaturated fat, like olive oil.” Dr. Gardner says. Besides the fact that olive oil is a monounsaturated fat, it also contains antioxidants compounds that help prevent chemical changes in the body that can cause the law-density lipoprotein (LDL) cholesterol to stick to the lining of artery walls. Sweet desserts made with sugar and saturated fat are consumed only a few times a week.

Nuts and seeds are the second-most common source of fats in the Mediterranean diet. Nuts contain alpha-linolenic acid, which is converted by the body to the same kind of heart-healthy fats we find in fish (which is also part of the Mediterranean diet). Studies have proved that people who eat the most of these fatty acids are the ones least likely to get heart disease.

The omega-3 fatty acids in fish that people in the Mediterranean countries eat have proved to reduce clotting and inflammation of the arteries, which decrease the risk of heart disease and stroke.
Following reports from the American Heart Association, clinical trials have shown that cases of cardiovascular disease decreases, when people consume omega-3 fatty acids, especially when it comes
from fish and plant foods, rather than from supplements.

Physical Activity
People in Mediterranean countries also take plenty of exercise, in the form of walking, hard physical labor, and stay active in general. They usually keep their weight under control, although they take in a lot of calories.

Five-a-Day Protection
The people at the American Heart Association would be happy if they could get us to eat the five servings of fruits and vegetables that people in the Mediterranean countries eat every day.
The Mediterranean diet prefers seasonally fresh and locally grown fruits and vegetables rather than highly processed foods that don’t contain as many micro nutrients and antioxidants.
Studies have shown that people who eat the most fruit and vegetables have lower rates of heat disease.

Also, fruits, vegetables and beans, which are a part of the Mediterranean diet, are one of the best sources of folate, a B vitamin that plays a big part in the prevention of heart disease.
Folate helps decrease the levels of amino acid called homosysteine. There is a link between too much homosysteine and heart disease. According to research, healthy people with high levels of homosysteine increase their change of getting heart disease about 14 times.

High Fiber
To add to all this is the fact that the Mediterranean diet is very high in fiber.High-fiber foods not only assist you by keeping your weight down by making you feel full without to much fat and calories, they also help
by blocking the absorption of certain fats and cholesterol. In other words, some of these harmful substances are flushed away before they can reach the bloodstream.
The powerful effects of fiber are shown by a study of almost 44,000 men, aged between 40 and 75 years, who added only 10 grams of fiber a day to their diet and lowered their risk of heart disease by almost 30%.

A Healthy Drink
The fact that wine, and especially red wine, is also included in the typical Mediterranean diet, also contribute to a healthy heart. Wine contains compounds, called phenols, that help prevent LDL cholesterol from sticking to artery walls It also keeps platelets in blood from sticking together and causing clots.
“In moderation, wine can be a nice addition to a healthy diet,’ says Robert M. Russell, MD, director and senior scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in
Boston.

Final Thoughts
Although the Mediterranean diet is most renowned for the fact that it helps to keep your heart healthy, it also appears to lower the risks of other health threats, like breast- and colon cancer. Studies showed
that compared with women elsewhere in the world, women in Mediterranean countries have less than half the risk of getting breast cancer. The reason for this could be the low intake of saturated fat and high intake of monounsaturated fat in fruits and vegetables.

“The message here is simple,” says Dr. Gardner, “For optimal health, choose a plant-based diet, which is naturally rich in vitamins, minerals, fiber, and antioxidants, low in saturated fat, cholesterol, and sodium.”

Avocados – No longer a Forbidden Fruit

Health & Nutrition, , , , ,

The well known characteristics of fruit, which is light, low-calorie, and fat free, does not apply to the avocado. An avocado contains a lot of calories -360 or more. And it is also one of the few fruits with a measurable fat content, about 30 gr. each. That’s almost half the daily recommended amount for an adult.

If you have doubts about the fact that a food that contains so much fat could be good for you, ask a dietitian. He will tell you that adding some avocado to your diet, could actually improve your health.

Avocados have high folate and potassium content. They are also rich in fiber and monounsaturated fat, both are important for people who are concerned about diabetes and heart health.

A favorite part of a Diabetes Diet
People with diabetes have always been told to eat more carbohydrates and cut back on fat. In general that’s good advice, but it hasn’t to be the best advice for everyone.

Doctors have discovered that when some people with diabetes eat a lot of carbohydrates, they tend to develop high levels of triglycerides, a type of blood fat that may contribute to heart disease. However, when people replace some of those carbohydrates with fat that’s found in avocados, the dangerous fats in the bloodstream tend to decline.

The monounsaturated fat in avocados are called oleic acid. They have found that this type of monounsaturated fat control fat levels in the body and help control diabetes.

Scientists in Mexico put 16 women with diabetes on a relatively high fat diet, with about 40% of calories coming from fat. Most of the fat coming from avocados. The result was a 20% drop in triglycerides. Women on a higher carbohydrate plan, by contrast, had only a 7% drop in triglycerides. Someone on a 2000-calorie-a-day diet might be advised to eat 33 gr of monounsaturated fat. You can get about 20 gr. from just one avocado.

Lowering High Cholesterol
Apart from people with diabetes, people with high cholesterol levels can also benefit from
the oleic acid in avocados.

In Mexico, where guacamole is considered almost a food group, researchers compared the effects of two low-fat diets. The diets were the same, except that one included avocados.
While both lowered levels of dangerous low density lipoprotein (LDL) cholesterol, the aocado diet raised levels healthy high-density lipoprotein, (HDL)cholesterol, while slightly lowering triglycerides.

Avocados also help in another way to lower bad cholesterol. They contain large amounts of fiber, Fiber adds bulk to the stool, causing it with the cholesterol it contains, to be excreted from the body quicker. One avocado contains more fiber than a bran muffin-10 gr or 40% of the Daily Value for fiber.

Support the Heart
Avocados are also a rich source of potassium. Half an avocado provides 548 mgr of potassium. 16% of the DV for this mineral. That’s more than you’d get from a medium banana or a cup of orange juice. Studies prove that people with a potassium rich diet, like avocados, have a significantly lower risk of high blood pressure and related diseases like heart attack and stroke.

In addition, some research has shown that oleic acid can reduce markers of inflammation in your body. Inflammation plays an important role in the development of artery-clogging atherosclerosis.

Rich in Folate
Another benefit from avocado is that it’s rich in folate, a B vitamin that helps prevent the threatening birth defects of the brain & spine. Many women don’t get enough folate in their diets, but avocados can go a long way towards fixing that problem. One avocado contains 114 micro grams of folate, which is 28% of the recommended Daily Value, or nearly 20% of the 600 micro grams that pregnant women need daily.

Minerals for your Bones
Avocado can help you to keep your bones healthy. A cup of mashed avocado contains 120 mgr of phosphorus, which is 12% of the DV. This mineral is a major component for your bones and teeth, and having plenty of phosphorus on hand also helps your body produce energy from the foods you eat.

Zinc for Good Nutrition
You’ll also find 1.47 mgr of zinc swimming in the green depth in a cup of mashed avocado.
That’s just under 10% of the DV. Zinc conducts countless activities in your body.
The mineral helps keep your immune system working properly, for example, and plays a role in wound healing.

Zinc also aids in your senses of smell and taste, which are necessary to be able to enjoy the food you eat.

Shopping for Avocados
If you live in the US, get your avocados from Florida. They provide all the nutrients without all the fat. They have about 2//3 of the calories and half the fat of Hass avocados. The best time to buy avocados is between November and March.
They may have one-third the fat of those picked in September or October.

Warning for Drug Users
People who are taking warfarin should take care when eating avocados. Researchers in Israel found that eating between one half and one avocado could make the drug work less efficient. While the effects didn’t last long,- when people stopped eating avocados,the drug started working better again – this could be dangerous for some people. So, if you’re taking warfarin,check with your doctor before adding avocados to your meals.

Help them ripen
Like bananas, avocados ripen better off the tree, so they are picked and sold unripe.
Once you get them home, leave them on the counter for several days until the fruit is
slightly soft. Or if you’re in a hurry toeat them, place them in apaper bag with an apple
or banana to soften. Never place hard avocados in the refrigerator, then they will ripen
too slowly.

Cholesterol Control

Health & Nutrition, , , , , , , ,

High Cholesterol levels is the cause of heart attack, stroke and other cardiovascular diseases.
Almost 100 million Americans have cholesterol levels over 200, of these about 34.5 million
have cholesterol levels of 240 or above.

But there is good news for these people. You can control the risk for heart disease by eating foods that contain less saturated fat and cholesterol. This is an efficient way to reduce the amount of cholesterol in your blood.

Facts about Cholesterol
People in general think that cholesterol is bad for you. But as a matter of fact, your body need cholesterol, which is produced in the liver to make cell membranes, sex hormones, bile acids, and vitamin D. You couldn’t live without it. Cholesterol is found in animal foods such as meats, milk, eggs and butter. But if you get too much of it, it becomes dangerous.

This is particularly true for the type of cholesterol called low-density lipoprotein (LDL).When LDL cholesterol circulates in the bloodstream, it undergoes a process called oxidation. In other words, it spoils and becomes rancid. Your immune system react to it as it would to any other invader. Immune cells gobble up the cholesterol molecules. Once engorged, they
stick to the walls of arteries, and hardening into a dense, fatty layer called plaque.When a lot of plaque accumulates, there is less room for blood to flow. Eventually blood flow may slow down and could even stop. When this happens in the arteries that supply the heart, the result is a heart attack. When it happens in the arteries supplying the brain, the result is
a stroke.

Your body has a mechanism for dealing with this threat. Another form of cholesterol, called high-density lipoprotein, (HDL), transports the dangerous type of cholesterol out of the blood and into the liver for disposal. Normally, it does a good job One study found that every one-point rise in HDL cholesterol protects the heart at least as much as a point drop in LDL
cholesterol, reducing risk of a fatal heart attack by 2%. But when cholesterol levels get too high, the HDL cholesterol can’t keep up, and LDL gradually rises to dangerous levels.

Ideally, you want to have high levels of HDL cholesterol and low levels of the dangerous LDL. The National Cholesterol Education Program recommends keeping total cholesterol below 200 milligrams per deciliter of blood. Actually, LDL should be below 130, and HDL should be above 40. An HDL above 60 would be even better to protect against disease.

A good way to keep your blood cholesterol level within healthy limits is to eat no more than 300 milligrams of dietary cholesterol a day (a little more than the amount in 11/2 egg yorks). But because the body itself makes cholesterol, limiting the amount of cholesterol in your diet is only part of the solution.

Saturated and Monounsaturated Fat
“The component in food that has the most effect on blood cholesterol levels is saturated fat”, says Mark Kentor, PhD, of the University of Maryland, College Park. Saturated fats, which are found mostly in animal foods such as red meats, milk, egg yolks, butter and cheese, can increase the amount of harmful low-density lipoprotein (LDL) cholesterol in the bloodstream as well as the total amount of cholesterol.

Every day, the Average American eats the fat equivalent of a full stick of butter. Experts strongly recommend to decrease the amount of fat in your diet.

But there is one time of fat you can eat moderate amounts of and that is monounsaturated fat, which you find in avocados, olive oil and canola oil. It can lower levels of bad LDL cholesterol, while leaving the beneficial high-density lipoprotein (HDL) untouched.

Researchers have known for a long time that people in Mediterranian countries where olive oil is consumed every day, have some of the lowest rates of heart disease in the world, even when their cholesterol levels are fairly high.

But we can’t give all the credit to olive oil for all the benefits. People in the Mediterranian region also eat a lot of fresh fruit and vegetables, plus they walk more than Americans and are less likely to be overweight.If you decide to add more olive ol to your diet, use it in moderation, and cut back on all fats.

Health benefits of Nuts
One of the many health benefits of nuts is their ability to reduce the level of LDL cholesterol.an Scientists at the USDA found that nuts contain significant levels of nutrients called plant sterols. These nutrients can lower LDL cholesterol, possibly by keeping your digestive system from absuntorbing the cholesterol in the foods you eat. Researchers in Canada found that when people with high cholesterol levels in their blood, ate 1.8 grams of plant sterols a day, their cholesterol levels dropped by 8%.

You can find sterols in sesame seeds, 144 mg, sunflower seeds, 104 mg and pistachios, 83 mg. in 1/4 cup. Coconut got a bad reputation because it contains more saturated fat than butter, however, more than half of the saturated fat in coconuts is lauric acid. Research discovered that even though lauric acid raises LDL cholesterol, it boosts HDL cholesterol even more.the al So in the long run, this is good for your overall cholesterol profile.

An even more favorable nut than the coconut is the almond. Researchers at Tufts University found that the skin of almonds are rich in antioxidants that help to remove LDL cholesterol. They found that extract of almond skin flavonoids reduced LDL oxidation by 18 % in hamsters.

Eat one to two fistfuls of almonds per day. This amount – 1 to 2 ounces – or raw, unblanchedalmonds each day gives a significant reduction of cholesterol in a University of Toronto study. Even better: the addition of this amount of almonds to the diet didn’t result in any weight gain.

Fiber Support
Besides eating whole grains, beans and fresh fruits to help keep your digestive system in top shape, you will also reduce your cholesterol level by eating these foods. They are filled with soluble fiber, a substance that forms a gummy gel in the digestive tract, which helps lower cholesterol levels.

Researchers from the USDA put 25 people on heart-healthy diets for 5 weeks.
They gave some of the people 3 grams of soluble fiber each day from barley – about the amount in a half-cup. When compared with the other people, who didn’t get the barley, their total cholesterol level dropped by 9%.

The Daily Value of fiber is 25 grams. This is equivalent to eating 2 to 4 servings of fruits, 3 to 5 servings of vegetables and 6 to 11 servings of breads, cereals and grains each day. Eating oatmeal or oat bran cereal several times a week will add even more soluble fiber to your diet. Other good sources of soluble fiber include pinto beans, red kidney beans, Brussels sprouts and sweet potatoes.

Benefits from milk and wine.
These two very different beverages may help improve cholesterol levels. Fat free or low-fat milk is best. According to a research, after 4 weeks of consuming 1,060 mg of calcium, 490 mg of phosphorus ( a combination found in dairy products) in supplement form, the cholesterol levels of healthy people were reduced by 6%, compared with people who didn’t get the supplements. One 8-ounce glass of milk contains about a third of the amounts taken in the study.

Another study, conducted in Boston, found that drinking an average of 5 wine drinks a week cut the risk of having dangerously low HDL levels by a whopping 78%. It’s important to keep in mind that drinking more heavily can raise blood pressure, which is another risk factor for heart disease, and can have other damaging effects on your health.

Asian Super food
Asian people eat soybeans and other soy products like tofu, which contain a compound called phytostrogens, which lowers total cholesterol levels and LDL cholesterol levels. These compounds help to transport LDL cholesterol from the blood stream to the liver, where it’s broken down and excreted. They also may prevent LDL from oxidizing, which helps to avoid clogging of coronary arteries. To get the benefits of lowering cholesterol levels you have to eat two or three servings of soy foods per day.

Marine Support
Besides watching your cholesterol levels, there is another factor to watch: your level of blood fats called triglycerides. People with high levels of triglycerides are more likely to have low levels of protective HDL. Conversely, lowering your level of triglycerides can help decrease your risk of heart disease.

Salmon, tuna, mackerel and other oily fish contain omega-3 fatty acids, which have proved to lower triglycerides. Omega-3 may raise levels of beneficial HDL cholesterol as well.Fish is also low in calories and saturated fat. To get the maximum benefits from omega-3s, plan on eating 3 to 4 ounces of fish two times a week.

The Healing Power of Vegetarian Diets

Health & Nutrition, , , , , , , , , , , , , ,

In the 1960’s chefs started to experiment with cooking without meat.
But the meals were often tasteless. But now-a-days after experiencing
for more than a quarter of a century, cooks are combining fruits, vegetables
grains, and legumes in exciting new ways. The tastes are so good that even
large restaurants are now offering meatless meals.

As a result, more than 30 million Americans, including one in three teens,
have tried vegetarian meals, according to the American Dietetic Association.
They like the health benefits and how good the food tastes.
Vegetarian diets have changed, but one thing stayed the same: a plant based diet ,
which is low in saturated fat, high in fiber,vitamins, antioxidants, and a powerful
array of protective chemicals. This is the ultimate prescription for a longer and
healthier life, according to Virginia Messina, MPH, R.D. a dietitian in Port Townsend,
Washington, and coauthor of The Vegetarian Way.

Research results have showed that vegetarians have lower rates of cancer, heart
disease, high blood pressure, type two diabetes and obesity than people who eat meat.
According to British researchers, vegetarians have a 20% lower risk of fatal heart
disease and a 40% lower risk of cancer.

Other studies found more positive facts. Fifty years ago a large study of 27,530
Seventh-Day Adventists, whose religion advocates a vegetarian diet, provided the
first scientific link between vegetarian diets and better health.
Researchers were amazed to discover that among the vegetarian Adventists,
death rate from cancer were 50 to 70% lower than among other Americans.
Since then, study after study has confirmed the benefits of vegetarian eating.

In China, where people eat little or no meat, diseases such as heart disease,
breast cancer and diabetes, are far less common than in the United States.

Naturally lean
Something that makes vegetarian meals so healthy is that they don’t have all the
saturated fat and cholesterol that comes from meat. In fact, while most Americans
get about 36% of their total calories from fat, vegetarians get less, usually
between 30% and 34%. And most of the fat they get is the healthier polyunsaturated
and monounsaturated type – and not the dangerous saturated fat that comes from
animal foods.

In one study, researchers put 500 people on a vegetarian diet. After twelve days,
cholesterol levels had dropped an average of 11%.

Besides the fact that vegetarian meals don’t contain saturated fat that makes
vegetarian meals so healthy, they also contain the “good” fats.
According to studies, both polyunsaturated and monounsaturated fats, which are
found in olive oil, canola oil, nuts, seeds, and many other plant foods, can lower
the level of cholesterol when they’re used to replace saturated fat in the diet.
And the omega-3 fatty acids found in some plant foods, such as walnuts and
flaxeed, can further protect against heart disease by helping to keep artery walls
flexible and supporting the electrical “system” within the heart that regulates
a healthy heartbeat.

The Power of Plants
Doctors in the US have been pleading with Americans for years to eat more fruits,
vegetables, whole grains, and legumes, the same foods that vegetarians eat in
abundance. Most plant foods are loaded with antioxidants, like beta-carotene and
vitamin C and E. They are essential to protect you against diseases.
Also, plant foods contain an abundance of phytonutrients, which are natural plant
compounds that have been shown to lower the risk of cataracts, heart disease,
and many other serious problems.

In another study researchers found that people who got the most carotenoids,
the plant pigment that are found in dark green and deep orange, yellow, and red
fruits and vegetables, had half the risk of developing macular degeneration
(the leading cause of irreversible vision loss in older adults) as people getting less.

Vegetarian diets cut the risk of breast, colon, ovarian, and prostate cancer in a
number of studies. The magic ingredients include a number of cancer-fighting
phytochemicals. The naturally lower levels of saturated fat in most vegetarian diets
(except those that rely heavily on cheese) avoid a problem which is connected
with meat-rich diets: High-saturated fat diets seem to promote the production of
a form of estrogen called estradiol, which is linked to breast cancer.
In a study it showed that women who ate the most animal fats had a one-third
higher risk of breast cancer than those who ate the least.

Another study found that vegetarians have higher levels of “natural killer cells” –
special white blood cells that attack cancer cells – in their bloodstreams.

But even if you took all the nutrients out of plant foods, the vegetarian diet
would still have an edge, because of all the dietary fiber it contains.
The average American gets only 12 to 15 grams of fiber per day,
while vegetarians are getting as much as three times that amount.

It is almost impossible to exaggerate the importance of getting enough dietary
fiber. because it isn’t absorbed by the body, fiber passes through the
digestive tract, adding bulk to stools and helping them to move more quickly.
This does more than preventing constipation. The more quickly stools
and any harmful substances they contain move through the colon,
the less likely they are to do cellular damage that could lead to cancer.

Also, one type of fiber called soluble fiber, forms a gel in the intestine that
helps to prevent fat and cholesterol from passing through the intestinal wall
and into the bloodstream. In a study of more than 43,000 men, for example,
researchers found that those who added just 10 grams of fiber a day to their
diets – about 25% of the amount vegetarians get each day – decreased their
risk of heart disease by almost 30%.

Vegetarian diets also guard against other health issues, like kidney stones,
gallstones, and asthma. Because high-protein diets with much meat prompt
your body to excrete more calcium, oxalate, and uric acid – which are the
main building blocks of kidney stones. Diets with a lot of meat increase
the change of getting gallstones in women and could threaten bone density
by prompting the excretion of calcium.

In a Swedish study of 24 women and men, vegetable-based meals cut
the frequency and severity of asthma attacks.

Balance is the Key
A vegetarian diet can provide all the nutrients your body needs, including protein.
This is even true for strict vegetarians, who may avoid eggs, milk and other
animal foods all together. The proteins in meat are complete, that means they
contain all the amino acids your body needs.
The proteins in legumes and grains, however, may be low in one or more of the
amino acids, but because legumes and grains contain some amino acids, eating
a variety of these foods throughout the day will provide the proper balance.

However, vegetarians have the risk of vitamin B12 deficiency, which the body
needs to make red blood cells. It’s only found in animal foods.
People who don’t get enough vitamin B12 feel weak and tired.
You can get plenty of vitamin B12 by eating foods which are fortified with this
nutrient, such as fortified cereals, or/and you can take vitamin B12 supplements.

The Mediterranean Diet – A Model for Good Health

Health & Nutrition, , , , , , , , ,

When the heart disease rate in the United States was skyrocketing during the early 1960s, people in Greece had some of the lowest heart disease rates in the world. But the most remarkable fact about this is that they were enjoying this robust good health even though their diet racked up nearly 40% of its calories from fat plus they generally washed down their meals with a glass or two of wine.

Scientist searched the shores of the Mediterranean Sea and they discovered that it was not only the Greece people who were living longer but also in neighboring nations like France, Italy and Spain. Clearly, these folks were onto something, but what?

Here is what Christopher Gardner, PhD, assistant professor of medicine at the Stanford Prevention research Center in Stanford, California has to say about it:
“For one thing, the traditional Mediterranean diet includes a lot of vegetables and legumes, along with fruits,
fresh whole-grain breads, dates, and nuts. Meats like lamb and chicken are consumed infrequently and in small portions,
and the main source of fat in the diet is monounsaturated fat from olives and olive oil, rather than the saturated fat
from animal foods.
In addition, physical activity is a big part of their daily routine”, he adds.

But just how healthy is the traditional Mediterranean diet? In one study French researchers looked at 600 men
who recently had a heart attack.
They put half of the men on a traditional Mediterranean diet and half of them on a low-fat, low cholesterol diet
that people with heart disease are typically told to follow. Those who followed the traditional Mediterranean diet
had a 70% lower rate of recurrent heart problems than those following the prudent low-fat diet.

Other studies showed similar results. When researchers examined the diets and disease rates of people
in seven different countries, they found that, while heart disease accounts for 46% of deaths of middle-aged men
in America, only 4% of men on Creta, an island in the Mediterranean Sea,had similar problems.
In fact, the death rate from all causes in Creta during this 15 year study was lower than that of the other countries

In 2006, researchers reviewed 35 experimental studies of the Mediterranean diet and found that the diet had
a positive effect on cholesterol and insulin resistance. Researchers also found that the diet also lowers
the risk of metabolic syndrome, heart attack and heart disease, and the risk of cancer
in obese patients and patients who have had a heart attack.

One study found that, in addition to the health benefits. people find it easier
to stick to a Mediterranean diet compared with a low fat diet.
A group of 772 older adults in Spain who had diabetes or three or more
risk factors for heart disease were assigned to one of three groups.
Two groups followed a Mediterranean diet, and the third followed a low-
fat diet. In addition to the Mediterranean diet contributing to lower blood
pressure, cholesterol and blood sugar levels after three months, it also made
it easier for the study participants to maintain the diet, researchers say.

The Fat Factor
The most important factor in the Mediterranean diet is that it uses fat
from olive oil, with total fat intake of 25 to 35 percent of total calories.
Even though people in Mediterranean countries eat as much fat as we do
(or more), they eat relatively little meat. Red meat is eaten only a few times
a month, while fish and poultry are eaten every week.

This means that they consume only minuscule amounts of artery-clogging
saturated fat. “The big difference comes from limiting saturated fat and
replacing it with monounsaturated fat, like olive oil,” Dr Gardner says.
Besides olive oil being a monounsaturated fat, it also contains antioxidant
compounds that help prevent chemical changes in the body that can cause
the dangerous low-density lipoprotein (LDL) cholesterol to stick to the
lining of artery walls.
Sweet desserts made with sugar and saturated fat are consumed no more
than few times a week.

The second-most common source of fats in the Mediterranean diet is nuts
and seeds. Nuts contain alpha-linolenic acid, which the body converts to
the same kind of heart-healthy fats we find in fish ( which is also part of
the Mediterranean diet). Studies have proved that people who eat the most
of these fatty-acids are the ones least likely to get heart disease.

The fish that people in the Mediterranean eat contains omega-3 fatty acids,
which have been shown to reduce clotting and inflammation in the arteries,
and thus significantly reducing the risk of heart disease and stroke.
The American Heart Association reports that epidemiological and clinical
trials have shown that cardiovascular disease incidence decreases when
people consume omega-3 fatty acids, especially when it comes from fish
and plant foods as apposed to supplements.

Physical activity
People in Mediterranean countries also take plenty of exercise, in the form
of walking, hard physical labor, and generally stay active.
So even though they take a lot of calories from fat, they’re usually able to
keep their weight under control.

Five-a-Day Protection
The folks at the American Heart Association would be delighted if they
could get us to eat the five servings (or more) of fruits and vegetables
that people in the Mediterranean region eat every day.
The Mediterranean diet emphasizes seasonally fresh and locally grown
fruits and vegetables over highly processed foods that don’t contain
as many micro nutrients and antioxidants.
Studies have shown that people who eat the most fruit and vegetables
have fewer problems with heart disease. Presumably this is due to the
antioxidant vitamins and healing compounds in these foods.

In addition, fruits, vegetables and beans, which are another Mediterranean
staple, are among the best sources of folate, a B vitamin that may work
hard in the fight against heart disease, says D. Gardner.
Folate helps decrease levels of an amino acid called homosysteine.
There is a link between too much homosysteine and heart disease.
Research has shown that healthy people who have high levels of
homosysteine have about 14 times more change of having heart disease

High Fiber
On top of all that, the Mediterranean diet is extremely high in fiber.
High-fiber foods not only help to keep your weight down by filling you up
without a lot of fat and calories, they also help block the absorption of
certain fats and cholesterol. This means that some of these harmful
substances are flushed away before they can make it into the bloodstream.
How powerful the effects of fiber are shows a study of nearly 44,000 men,
aged between 40 and 75, who added just 10 grams of fiber a day to their
diet decreased their risk of heart disease by almost 30 percent.

A Drink for Good Health
Another factor that contribute to a healthy heart is the fact that wine,
and especially red wine, is also included in a typical Mediterranean diet.
Whine contains compounds called phenols that help prevent LDL
cholesterol from sticking to artery walls. It also keeps platelets in blood
from sticking together and causing clots. “In moderation, wine can be
a nice addition to a healthy diet,” says Robert M. Russell, MD, director
and senior scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston.

Final Thoughts
Although the Mediterranean diet is most renowned for its role in helping
to keep the heart healthy, it also appears to reduce the risks of other
health threats, among them cancer of the breast and colon.
Studies show that compared with women elsewhere in the world, women
in some Mediterranean countries half half the risk (or less) of getting breast
cancer. This could be due to their low intake of saturated fat and high intake
of monounsaturated fats, fruits and vegetables.

Indeed, Italian researchers have found that people in the Mediterranean region
who follow the traditional diet – that is, those who eat lots of fruits and
vegetables and not much fat and protein – are less likely to get cancer than
those who eat more modern, less-healthful diets.

“The message here is simple,” says Dr. Gardner. “For optimal health,
choose a plant-based diet, which is naturally high in vitamins, minerals, fiber,
and antioxidants, and low in fat, cholesterol, and sodium.”

Healthy for Life with a Healthy Heart

Health & Nutrition, , , , , , , , ,

Only about 50 years ago, doctors didn’t know what was good for our hearts.
Little attention was paid to diet and even smoking was acceptable by some.

But after almost 50 years, scientists came up with some simple and straight forward answers. Regular exercise is important, of course, and so is staying away from cigarettes.

But by far the most important factor is to have a healthy diet. Eating the right foods is
the most effective way to lower cholesterol and high blood pressure, two of the biggest enemies against a healthy heart.

The Bad Fats
Often we take the wrong foods, in particular fats. There are good fats and bad fats.
The bad fats are saturated fats, found in red meat, and butter, It’s incredible dangerous
for the heart. Study after study has shown that the more saturated fat people eat,
the higher their risks for heart disease.
Foods high in saturated fat raise levels of artery-clogging low-density lipoprotein (LDL cholesterol. Foods high in saturated fat are often high in cholesterol as well.

The American Heart Foundation recommends that we limit our intake of saturated fat
to less than 7% of our calories each day. For example, if you get 2,000 calories a day,
your upper daily limit for saturated fat is 14 grams.
That means: in addition to eating fruits, vegetables, and other low-fat foods, you could have 3 ounces of extra-lean ground beef which contains 5 grams of saturated fat), a serving
of macaroni and cheese (6 grams), and a half-cup of low-fat frozen yogurt (3 grams).

Another problem fat, called trans fatty acids, has been shown to dramatically increase
the amount of cholesterol in the bloodstream. Trans fatty acids are made when manufacturers add hydrogen to vegetable oils to turn the liquid oils into solid fats like margarine and shortening. Ironically, they meant to be a healthy alternative to the saturated fat in butter.
But it appears that trans fatty acids may be even more harmful than saturated fats.
Trans fats raise the bad (LDL) cholesterol and lower the good (HDL) cholesterol,
increasing the risk of cardiovascular disease, heart attack and stroke.

It’s not only margarine and fried foods that may be a problem. Many cookies, cakes, and
other snack foods contain “partially hydrogenated oil,” which is also high in trans fatty acids.
Because of the health risk, the American Heart Association recommends you limit your
daily intake to less than 1% of your total calories.

Some Better Fats
Some fats are relatively healthful. You can easily recognize them by looking at the “un”
as in polyunsaturated and monounsaturated fats. While theses type of fats are still high in
calories, in small amounts, they play several beneficial roles.
Polyunsaturated fats (found in soy, corn, safflower, sesame, and sunflower oils, as well as
nuts and seeds ) help your body to get rid of newly formed cholesterol, therefore, they
keep cholesterol levels down and reduce cholesterol deposits on artery walls.

Monounsaturated fats also appear to help lower cholesterol levels as long as the rest of
the diet is very low in saturated fats. Although they are a good substitute for saturated fats,
both polyunsaturated and monounsaturated fats should be used in moderation, because
their high calorie counts can lead to weight gain. No more than 30% of your calories
should come from fat.

Nuts are particularly good sources of these healthful fats. In a study of Seventh-Day
Adventists, researchers found that those who consumed nuts at least four times a week
had almost half the risk of fatal heart attacks of those who rately ate them.

Although the American Heart Association recommends less than 30% of calories from fat,
many health-care professionals, recommend even less.
They tell people to aim for getting about 20 to 25% of total calories from fat, most of which
should be in the form of monounsaturated and polyunsaturated fat.

There is yet another kind of healthy fat, perhaps the king of healthy fats, called omega-3
fatty acids. This is found in most fish (but in particularly in oily, cold-water fish) and also
in flaxseed and certain dark greens. Omega-3 can help to prevent clots from forming in the
arteries. In addition, they help lower triglycerides, a type of blood fat that, in large amounts, may raise the risk for heart disease.

Studies show that eating fish twice a week, in particularly salmon, because it contains
high levels of omega-3, can help to keep your arteries clear and your heart working well.
In a stuy done at the Harvard School of Public Health, scientists found that the death rate
from heart disease was 36% lower among people who ate fish twice a week compared
with people who ate little or no seafood. The study, which was published in the American
Medical Association, also showed that overall mortality was 17% lower omong the regular
seafood eaters.
