I am reading a lot about nutrition and digestion. I will give some extracts of books, magazines and documents I read respectively watch. As such you will have the most important ideas at a glance. As such, these are not my personal studies, but just repetition of someone’s else studies.
Book: Die Heilung der Mitte (Healing of your “middle”)
Author: Dr. med. Georg Weidinger
The main question that will be answered in the following extract ist: What does our anatomy tell us regarding what we should eat?
Within the first 50 pages of the book, Dr. med. Weidinger who is a Western doctor since 15 years and recently discovered the world of TCM, evaluates on what our anatomy already tells us about the food we can and should eat.
Let’s start with where the food first enters our body: The mouth
The first step of diagestion is biting your food.
The human dentition looks different than that of a meat eater: A meat eater has large canines and sharp scissors teeth as molars. We also do not need these teeth because we do not have to tear an animal. In addition, the dental researcher Richard Lehne and Hans Lüttschwager say that meat is not the natural food of humans. You can tell by the fact that a human being tries to chew the meat. Whereas no other animal chews meat. Animals devour meat in swallowing bites.
Nor is an human an omnivore, because he lacks the anterior carnivorous part of the dentition (like a pig for example).
Humans are also not herbivores. Our molars are not nearly the shape of an herbivore. According to Brockhaus, we humans are fruit eaters. We naturally feed on fruits, nuts and roots in a natural way. The human dentition is designed to grind: due to the molars and because we can move our jaws sideways to just grind.
Another aspect that points to a fruit eater is our saliva. Our saliva is alkaline and contains enzymes that pre-digest carbohydrates in the alkaline range. In addition, we have a lot of salivary glands so we can mash our food, which in turn can be better digested. Carnivores have very few salivary glands. Since they immediately swallow down their food, they do not need saliva.
Another indication that humans are fruit eaters is the thickness of the enamel. Humans have a thicker enamel than chimpanzees or gorillas. Thicker enamel suggests harder foods such as nuts, roots and seeds. Meat is not chewed in comparison to it and therefore thicker enamel is a sign that meat is at least not one of the main foodstuffs.
As soon as the food leaves the mouth, it passes through the esophagus into the gastrointestinal tract.
This is built in animals very different depending on the food. Meat eaters have a flat stomach, a short colon and no or a stunted appendix, but the small intestine dominates.
Plant eaters, on the other hand, have a very long colon and a pronounced cecum. The small intestine, however, is much smaller. In terms of gut sizes, there are fruit eaters (ie humans) between plant and meat eaters, but on the edge towards meat eaters.
Compared to meat eaters, our stomach is much more complex. Meat eaters can break down food-borne uric acid (an excretory product from protein digestion) and produce vitamin C itself, so they do not have to feed it (as we do from fruits and vegetables).
Further, meat eaters can consume any amount of animal protein and show no signs of vascular wall calcification or arterial narrowing, have no elevated cholesterol or triglyceride levels. Conversely feeding plant-eaters such as rabbits with animal fats, those develop early on signs of vascular calcification and elevated cholesterol levels.
Last but not least, the physique of the humans is primarily not created for hunting.
On our two legs we are significantly slower than most predators and we have no natural weapons, such as sharp claws or canines, we cannot open our mouths to mortally kill. Our differentiated hands, as well as our upright walk, are ideal for gathering small things from the ground and stretching up to trees and shrubs to pick fruit.
