The Healing Power of Vegetarian Diets

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.

Healthy for Life with a Healthy Heart

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.
