The debate about the best diet for health (not weight loss) continues with the latest report from U S. News and World Report. Winning top awards are three diets: the Mediterranean Diet, the DASH diet and coming in third, the Flexitarian Diet. These diets are basically saturated fat restricted and recommend the conventional wisdom of a more plant-based approach of whole grains and fruits and vegetables in order to prevent heart disease and diabetes.
On the other hand, there are critics of the report that include the proponents of the low carbohydrate, high fat ketogenic (LCHF-keto) diet that is lately gaining some attention at least for weight loss and claims to reverse diabetes. Many of these claims appear to be anecdotal on the Internet. By the way, the LCHF-keto diet came in last in the report by the nutrition experts. See my previous post HERE.
It still remains to be seen conclusively if any of these diets can be protective against heart disease. There is a great deal of research on the Mediterranean Diet and the lower risks of many chronic diseases. To be fair, research on low carb diets is increasing due to interest on the LCHF diet claims for weight loss, diabetes prevention and lowering some risk factors of heart disease. At the heart of the conflict is whether saturated fat is an unhealthy or healthy fat. The LCHF diet recommends using saturated fat liberally.
Partisans of both sides may be right or wrong. One fact is that both are very restrictive and are very hard to follow for long periods of time, especially in our current food environment. There is fat and /or sugar (carbs) in almost every brand and type of processed food products. Often the food industry intentionally puts them there to increase the palatability of the product and to increase profits.
In the meantime, the best diet remains to be the food choices you make and can incorporate into your lifestyle whether it is vegan, low fat or low carb. One diet is not for everyone. It is important to consider your genetic background and health history. If you change your diet please consult with your physician for his/her opinions.
