Which diet is better for your heart – the Mediterranean diet endorsed by most nutritionists, or the ketogenic diet, or keto? A new study published in The American Journal of Clinical Nutrition offers some insight. Stanford researchers had 33 patients with prediabetes or diabetes follow both diets for a month, one after the other. They monitored the patients’ weight, blood sugar levels, adherence to the diets and more. They found that both keto and the Mediterranean diet improved blood glucose control. Both groups lost a similar amount of weight. But the ketogenic diet group had significantly higher levels of cholesterol in their blood. The researchers believe that those elevated cholesterol levels could be an important risk for cardiovascular disease. They propose that for most people, instead of eliminating fruits, whole grains and beans on keto, people might have better heart health eating more fruits, vegetables, beans, whole grains, nuts and seeds.
