If you answered mostly Bs, try the Mediterranean diet. A recent study found this diet alone, which is primarily made up of olive oil, nuts, vegetables, fruits, whole grains and fish, lowered the likelihood of developing diabetes among people at high risk of the disease — without the need to cut calories or exercise more. And previous studies documented a long list of possible health perks including lowering the risk for heart disease and memory loss. “Research shows that people with many types of health issues, including diabetes, heart disease, and depression could benefit from following a Mediterranean diet,” says Rachel Greenstein, the communications and licensing manager of Oldways, a non-profit group that encourages healthy eating and keeps a database of studies on the benefits of the Mediterranean diet. According to the folks at Oldways, the diet is best for someone who is looking for a lifestyle change, rather than simply lowering calorie consumption. The diet welcomes a variety of foods, include red wine, in moderation. But people who follow the Mediterranean diet do limit their intake of red meat and sweets. “A person that would enjoy the Mediterranean diet appreciates flexibility in building their meals and prefers cooking as a part of their lifestyle, says Greenstein.
