Some great obvious points here:
There is a universal wisdom to healthy eating. Pile on the fruits, vegetables and whole grains and skip the meat and saturated fat. Consume everything in moderation, especially alcohol. But certain cultures around the world offer further insight with traditional diets that are not just healthy, they also protect our bodies against scourges like cancer, depression, diabetes and heart disease. Researchers believe that following such diets can lead to excellent health; making the transition, however, requires more than just adopting an Americanized version of another culture’s traditional diet. – From Forbes
