MADRID, April 28 (EUROPA PRESS) –
A new study provided the first experimental evidence that the Mediterranean diet protects against the increase in consumption of calories, obesity and pre-diabetes compared with Western diets.
Scientists from the Wake Forest School of Medicine in Winston-Salem, United States, found that nonhuman primates with Mediterranean diets chose not to eat all the available foods and kept normal weight. "For comparison, animals with Western diets ate much more than they needed and gained weight," said lead researcher Carol A. Shibley, a professor of pathology at Wake Forest Medical School.
This study, published in the journal Obesity, is the first preclinical trial to measure the effects of long-term consumption of Western diets compared to the Mediterranean in obesity-related diseases in controlled trial conditions, Shibli explains.
Previous studies of the effects of diet on caloric intake were largely based on studies in the human population that relied on self-reported food consumption, which is often unreliable, or studies on rodents with non-dietary diets. human
The Wake Forest School of Medicine was a 38-month preventive study (equivalent to 9 years for humans), designed to accurately reflect human diets with proteins and fats derived primarily from animal sources in the Western diet and especially from plant sources in the Mediterranean diet. Two diets contain proportions of fat, protein, and carbohydrates.
The study involved 38 middle-aged women who were randomly assigned to the Mediterranean or Western diet. Both groups received the reference weight and body fat and were allowed to eat as much as they wanted during the study. "What we found was that the Mediterranean diet group actually ate fewer calories, had less body weight and less body fat than those in the Western diet," Shibli says.
The Mediterranean diet also protects against the non-alcoholic fatty liver, which can cause liver cirrhosis and liver cancer, and require transplantation. Obesity is one of its main causes. By 2030, a third of American adults are expected to have the disease, which is the rapidly growing cause of liver transplants among young people in the United States.
"The composition of nutrition is a critical contributor to public health, and unfortunately, people with a higher risk of obesity and chronic diseases associated with this problem also have lower quality diets," the researcher warns.
"The Western diet has been developed and promoted by companies that want us to eat their food, making it very nautical and we consume it too much, eating a Mediterranean diet should allow people to enjoy their food and not eat." We hope our findings will encourage people to eat healthy foods More than they enjoy and improve human health. "
