Lack of trace elements
Zinc, calcium, iron and other essential trace elements mainly come from meat, and long-term vegetarians are prone to cause some diseases due to the lack of trace elements.
decreased immunity
Meat food contains 8 kinds of amino acids necessary for human body, which is more suitable for human body to digest and absorb, and has higher lysine content, which is more conducive to supplementing the deficiency of lysine in plant protein. Not eating animal protein for a long time will lead to decreased immunity.
Increased risk of Alzheimer's disease
For most people, vitamin B 12 is unlikely to be deficient as long as they eat normally, but if they are vegetarian for a long time, it will lead to vitamin B 12 deficiency. Data show that if this vitamin is lacking, it will make red blood cells fragile and cause great damage to nerve cells, which will eventually lead to dementia.
cause constipation
Many people think that as long as they eat more fruits and vegetables and don't eat meat, they won't be constipated. In fact, the human body only has enough dietary fiber, and lack of water or oil can also lead to constipation. Because oil acts as a "lubricant" in the intestine. If women are too dieting, vegetarian and low in fat, there is no "oil and water" in their bodies, which will easily lead to constipation.
Forming gallstones
Vegetarian food contains more plant fiber, which can reduce the absorption rate of cholic acid and the concentration of bile salts. Vegetarians often have insufficient intake of vitamin A and vitamin E. The lack of these two vitamins makes gallbladder epithelial cells easy to fall off, leading to cholesterol deposition and stone formation.
Decline in fertility rate
A study found that if men are vegetarian in their daily lives, it will not only seriously affect their sexual function, but also affect their fertility, including female friends. Men who are vegetarian for a long time will be short of zinc or manganese. The deficiency of these nutrients will affect the secretion of gonadotropin by pituitary gland, which will lead to the decline of sexual ability, testicular atrophy and sperm count, and even lead to male infertility.
