The most famous method of food combining was developed by the British Herbert Shelton in the first quarter of the twentieth century. Having won the support of the movie stars and other celebrities, this talented organizer of a healthy lifestyle, not having a medical education, was introducing his ideas of food combining to the broad masses.
According to these ideas, human digestive juices, and namely, their enzyme constituents work much better, if products that contain an overwhelming majority of only one component enter the gastrointestinal tract at once: either it is a protein, or it is fat, or carbohydrates.
After the consumption of such mono-meal, we should give our body at least 2-4 hours to process it. Water consumption also has its strict limits.
For example, you are allowed to drink water:
Another very controversial principle of Shelton diet is to eat only when you feel hunger, which can happen just once a day.
People should not eat, when they:
have a headache.
Official science does not share the views of Shelton and his followers, noting that human gastrointestinal enzymes are always tuned to process different mixtures of any food.
Moreover, ‘loading’ only proteins or only carbs into the body leads to an overstrain of the enzyme systems over time.
Such regime requires very high differentiation, whereas over the millennia of human existence, its digestion could not be better adapted to multicomponent food with a universal response to it.
Shelton frightens with the formation of “putrefaction” in the intestines when incompatible products are combined. However, this risk is clearly repeatedly exaggerated.
