The Oxygenization Diet is a bit of pseudoscience, based on some strange theories about how oxygen affects our bodies, but the basic tenants of this diet conform to the recommendations of the medical establishment and registered nutritionists, which includes low fat diet, high in nutrients, along with cardiovascular exercise to make your body more efficient with oxygen.
The theory behind the diet is that fresh fruits, vegetables and grains have more oxygen than fat and protein. By consuming them, more oxygen will be in your system thereby making it more efficient. Whether it is the oxygen that does this or not, it is true that this course of diet will make your system more efficient and healthy. This diet is similar to vegetarian diets.
