The standard American diet is one of the worst systems of diets that I know, as it is the one that kills us. It is one of the three most deadly and dangerous diets to follow. The second, the Mediterranean diet, is a far healthier diet than the American diet, and the third, the ketogenic diet, is a far healthier diet than the American diet.
In order to get the most out of an American diet, you should eat a very small amount of meat, and then you should eat lots of veggies, fruit, and other healthy foods. In the case of the standard American diet, you should eat meat every single day, and that is not enough to ensure you have the nutrients you need.
