The Mediterranean diet is only effective for the rich

The Mediterranean diet is famous for its health effects. It sounds very healthy: a lot of fruits and vegetables, whole grains and beans, plus olive oil, red wine, and fish and poultry, but not red meat.

Now, a study from Italy confirmed that if you follow this diet, it will indeed reduce the risk of cardiovascular disease. However, the problem is that unless you are economically carefree or highly educated, this benefit will appear.

This discovery was recently published in the Journal of Epidemiology. The article stated that better adherence to the Mediterranean diet is associated with better cardiovascular disease protection, but not for low-income socioeconomic groups.

For four consecutive years, the researchers tracked 19,000 men and women living in southern Italy. After controlling habits such as smoking and exercise, the team found that volunteers who followed this diet were more protected from heart problems, but this was only for those who had received higher education or paid more than 47,000 a year. effective.

Scientists believe that individuals with higher incomes and education will tend to prepare vegetables in a healthier way, which may contain more vitamins and antioxidants. They also prefer fish and whole grain foods as well as organic vegetables. Maybe they can afford higher quality foods like better olive oil.

"You can buy two or three dollars a bottle of olive oil, or you can buy a bottle of ten dollars," said study author and epidemiologist Marialaura Bonaccio. "But it's quite possible that the two oils have different nutrient levels. For example in polyphenols or other nutrients." (Jin Nan)
