Usually carnivores need more gastric juice to digest the meat they eat, and their intestines are short, so that carrion can be excreted quickly. Many people love meat as much as carnivores, but because humans don't have the inherent function of carnivores-the acidity of our gastric juice is only half that of carnivores, so we can't digest meat quickly; Intestines are also much longer than carnivores, and carrion cannot be discharged quickly.
From the above analysis, it is not difficult to understand that human digestive system is actually closer to herbivores and more suitable for digesting high-fiber foods.
Therefore, experts believe that the first principle of health preservation is to eat more high-fiber plant foods, that is, vegetarian food.
If you can't give up meat, you should have a light diet, and you can't have too many kinds of food in each meal. Eating too complicated food is a burden to the stomach and the whole digestive system. For example, the digestion of carbohydrates and protein foods requires different digestive juices. If you eat at the same time, neither of them can be completely digested, which will lead to overdraft of stomach function.
Food that is not fully digested is also easy to accumulate and rot in the intestine, which provides an environment for harmful bacteria to grow, which is also one of the causes of cancer.
So the best way is to eat high-protein food instead of carbohydrates at the same time. For example, don't eat meat with rice and bread.
Vegetables can be paired with carbohydrates or beans, but fruits should be eaten alone.
If we abide by these principles, it will not cause too much burden on the stomach, lead to indigestion, and finally lead to various digestive system diseases.
It is best to eat some fresh and uncooked fruits, vegetables and sprouts for every meal. Their vitamins help prevent stomach cancer.
