Humans are regarded as omnivores generally, but many features of the human body are more like herbivores. So, what kind of food do humans belong to? Maybe after reading it, you will understand why there are so many vegetarians now.
Meat is not easy to stay in the body for a long time
If you have seen a kitten eat, you will find that it does not like to chew slowly, but swallows the food directly into its stomach. Because the canine teeth of carnivores are long and pointed, they are not suitable for chewing and grinding, but suitable for tearing meat; the digestive system of carnivores is also relatively simple and stubby, the total length is only equivalent to three times the trunk, because the meat is easy to decay. If meat stays in the body for too long, it will produce toxins and harm the body, so they will evolve a shorter digestive tract to expel the rotten meat as soon as possible. At the same time, the stomach of carnivores contains a lot of hydrochloric acid, which is good for digesting meat. Like fibers and bones.
The human intestine is made for plants
Human body structure is too different from carnivores. Humans have only 4 small tiger teeth that are not sharp, but have 20 molars, and more often they use molars to grind food. This is similar to herbivores. Herbivores have 24 molars; and humans and herbivores have 24 molars. Saliva contains salivary amylase, which decomposes and absorbs food when chewing grass or fruits. The length of the human intestine is 10 to 12 times the height of the human body. Such a long digestive tract is not suitable for meat to stay for too long, but it can slowly digest fruits, vegetables and seeds; and the hydrochloric acid contained in the human stomach is only the second of carnivores. One tenth is not enough to digest raw meat and bones.
Eating meat is “ill”
Eating meat for non-carnivorous animals can also harm their health. An American scientist once did an experiment, feeding white rabbits 200 grams of animal fat every day. After 2 months, the blood vessels of the white rabbits became hardened. Animal tissues contain many substances that directly increase the risk of cancer in humans, such as heterocyclic amines and polycyclic amines.
In the UK, heart disease and circulatory system diseases cause more than a quarter of deaths, and this has a lot to do with the cholesterol and saturated fatty acids in meat. They accumulate in the body and block arteries, prevent the heart from working properly, and increase the risk of heart disease.
Do you want to eat bloody raw meat?
Animals like cats, dogs, tigers, etc. will feel hungry and drooling when smelling raw meat, but humans will feel very sick when they see the bloody raw meat. They will find ways to cook, roast, deep-fry and other cooking methods, with various Seasoning changes the original bloody taste of raw meat and makes it easier to digest by the stomach.
If there is a rabbit, would you instinctively bite it with your teeth and suck its blood? You will not, but you will drool when you see a crystal clear fruit, and after eating the fruit, the fruit will feel very sweet.
Therefore, the human physiological structure and intuitive instinct do not seem to be born for eating meat, but for eating and digesting vegetarian food such as fruits, vegetables, nuts, and cereals.
