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.”
