The Mediterranean diet doesn’t benefit everyone, examine says

( CNN) The Mediterranean diet can reduce health risks of cardiovascular disease, yet merely people with higher incomes or more education, or a combination of the two, experience this benefit, discovered a study published Monday in the International Journal of Epidemiology.

The Mediterranean diet underscores feeing plant-based foods, including vegetables, nuts, fruits and whole grains, in addition to fish and poultry. The diet also recommends that you restriction red meat, replace butter with olive oil, and exercise.Red wine in moderation is optional on the diet, which past scientific research proves to be heart-healthy.

Marialaura Bonaccio, lead author of the new study and a researcher at IRCCS Istituto Neurologico Mediterraneo Neuromed, an Italian Clinical Research Institute, said in an email that this same problem — in which people from different income levels get different results from the same diet — may also be true for other diets.
