Mediterranean is a kind of vegetable-heavy diet that avoids a lot of meat, but does not eliminate it altogether. This diet has been proven to help with depression, in addition to controlling blood sugar levels and helping with weight loss.
The Mediterranean diet recommends the use of oil as much as possible and that means as an alternative to butter, salad dressings or marinades. It also emphasizes adding vegetables to each meal and favors fish over chicken. Whole grains, nuts and herbs are also used in larger amounts.
