Diet For Healthy Heart New Study

Mediterranean diet increases heart health condition

Diet for a healthy heartA Pour over olive oil, preferably on fish and vegetables: A test suspect the longest and the most scientific of the Mediterranean diet suggests that this type of diet can reduce the risk of heart problems, including strokes, elderly people with a high risk of them.

The study lasted five years and involved about 7,500 people in Spain. Those who ate a Mediterranean style, with lots of olive oil or nuts a risk 30 percent lower major cardiovascular events compared with those who follow a low fat diet, but said in reality, does not reduce the fat much more. Mediterranean was a lot of fruit, fish, chicken, beans, tomatoes, wine and salads and baked goods.

Mediterranean diet has long been considered healthy for the heart, but it is on observational studies can not prove it. The new research is much stronger, because people were assigned to follow diets for long and carefully controlled. Doctors have even laboratory tests to verify that the Mediterranean diet subjects, more olive oil or nuts consumed as recommended.

Most of these people were not changing medications for high cholesterol and high blood pressure, and the researchers examined the treatments, said a leader of the study, Dr. Ramon Estruch, Hospital Clinic of Barcelona.

But as a first step in the prevention of heart disease, "we believe that the food is better than drugs", because it has little or no side effects, with Estruch. "Regime works."

The results were published in New England Journal of Medicine published and discussed at a conference of nutrition at Loma Linda, California. The people in the study were not fixed menus or weight loss goals in calories because it's not the goal. This is perhaps why it the "Plans" found easy to follow - just 7 percent in two years in retirement. There were twice as many dropouts in the group with low fat than those who eat a Mediterranean style. So it is a best diet for a healthy heart.

The researchers have also provided nuts and olive oil, so it does not cost to the participants to use these relatively expensive ingredients. The type of oil can be imported - the extra virgin olive oil that is minimally processed, used and richer than regular olive oil or light in the chemicals and nutrients, which previous studies have suggested that they are useful.

The study included people aged 55 to 80 years, more than half are women. All were free of heart disease at the beginning, but they were at high risk of suffering due to health problems - half had diabetes and most were overweight and high cholesterol and blood pressure.

The patients were divided into three groups: two followed a Mediterranean diet with extra virgin olive oil (4 tablespoons per day) or with walnuts, hazelnuts and almonds (a handful per day) supplements. The third group was asked to eat a low fat diet heavy on bread, potatoes, pasta, rice, fruit, vegetables and fish and light in baked goods, nuts, oils and red meat.

Independent observers stopped the study after almost five years, if they have less problems in both groups saw with Mediterranean diet.

Doctors, followed by a combination of heart attack, stroke and heart-related death. There were 96 of them in olive oil Mediterranean group, the 83rd in the Mediterranean group and 109 in the parent group lowfat

Considered separately, stroke was the only problem with this type of diet makes a big difference. The regime had no effect on overall survival mortality rates.

The Mediterranean diet was better in spite of his disciples ate about 200 calories more per day than the low-fat group did. Investigators are now looking like any plan, the gain or loss of weight and body mass index.

Spanish government initiated Agency for Health Research and funded the study, and the food was provided by olive oil and nuts in Spain and the California Walnut Commission are available. Many authors have extensive financial ties to the food, wine and other industrial groups, but said that the authors not involved in the study design or analysis and reporting of results.

Rachel Johnson, University of Vermont professor who heads the Committee on Nutrition American Heart Association, says that the study is very high because of laboratory tests to check the consumption of oil and nuts, and because researchers and real-time monitoring of heart attacks, strokes death - not only changes in risk factors such as high cholesterol.

"At the end of the day, what matters is whether the disease develops," he said. "This is an important study."

Rena Wing, an expert in weight loss at Brown University, the researchers said, provided the oil and nuts, and said that "it is not clear whether people can achieve the same results Mediterranean diet self-designed" - or if the Americans stick to the more than Europeans, who are used to this kind of food, diet for a healthy heart.
