There are countless reasons for vegetarianism: health, environmental protection, health preservation, beauty, economy, animal protection ..... More in-depth researchers associate vegetarianism with the supreme topic of saving the earth's ecological environment and saving human life. But for many heartless and unhappy people, questioning has a great impetus. Next, let's look at their doubts.

1. How do vegetarians supplement protein?

Protein accounts for 20% of the human body, accounting for the largest proportion of the body. The muscles, bones, internal organs, brain, nerves and skin of human body are all made up of protein. Protein is sufficient for normal metabolism. It is the material basis of life. Without protein, there would be no life. Therefore, protein's supplement has aroused the greatest concern. Is plant protein really not as high as animal protein? Let's take a look at the following comparison table:

The results show that a healthy and light vegetarian diet contains more protein. When we eat chicken, duck and fish that are considered to be very nutritious, we also bring a lot of cholesterol, fat and calories to our bodies. Too much cholesterol and fat will directly lead to diseases such as hypertension, hyperlipidemia and heart disease.

The incidence of "rich disease" is increasing year by year, which brings a lot of harm to human health and life expectancy. However, the content of protein in cereals is as high as 50%, and the content of cholesterol and fat is extremely low, so FAO strongly recommends plant protein.

2. Will vegetarianism lead to calcium deficiency?

Calcium is one of the indispensable nutrients for human body and the foundation of human life. From bone formation, muscle contraction, heart beating, nerve and brain thinking activities, to human growth and development, eliminating fatigue, strengthening brain and improving intelligence, and delaying aging, it can be said that all sports of life are inseparable from calcium. So which food contains more calcium, plant food or animal food?

Drinking 1 cup of soybean milk can supplement the calcium of 2 cups of milk. Calcium is alkaline, and milk is neutral food before disinfection, but milk becomes acidic food because the human body can't absorb calcium or seldom absorbs it.

In order to neutralize this acidity, the body can only mobilize the calcium stored in the body, because calcium is the best substance to neutralize acidic foods. The largest organ for storing calcium in the body is the bone, which leads to the loss of calcium in the bone. In this way, the density of bones will be reduced, and drinking milk for a long time will lead to osteoporosis of bones.

Many people think that eating seafood can supplement calcium. As it turns out, a bowl of seaweed soup supplements about 20 times as much calcium as an equivalent seafood product. Now the mercury content in seafood is getting higher and higher. Mercury is easily absorbed in human intestine and transported to various organs of the whole body, especially liver and kidney, of which only 65,438+05% enters brain tissue. However, the brain tissue is damaged first, so there are clinical manifestations such as decreased centripetal vision, dyskinesia and acrosensory disturbance. Therefore, health and disease are your own choices. It is extremely important for us to choose healthy and nutritious food.

3. Can vegetarianism lead to anemia?

The elements that make blood are iron, vitamin B 12 and folic acid. Everyone knows the importance of blood to human body, so is the iron content of plant food lower than that of animal food? The chart tells us:

Facts have proved once again that a plate of fried mushrooms with auricularia auricula can supply about 5 times more iron to human body than a plate of seafood. The meat we eat now is very different from the meat raised in the countryside decades ago. Cattle, sheep and pigs used to live in a mountain village with a very good environment, eating pollution-free weeds and living in a walking pigsty.

However, due to the huge demand for meat, more and more animal husbandry will inject hormones into their animals in order to increase production. The pigs and chickens there can't even stand up because their legs can't bear their own weight. Cattle and sheep can't be raised on the natural prairie. Thousands of animals are imprisoned in their own narrow space like prisoners, and their unhappy lives have been destroyed and tortured countless times.

Nowadays, most meat is associated with various hormones, anger and diseases, and eating it will not bring us any benefits! Just eat more harmful substances through such a carrier.

4. Can I eat seafood without meat?

In addition to people who are unhappy without meat, there is another kind of people who just don't eat meat very much, but think that seafood can be eaten more and is more nutritious than meat. However, in the United States, after a large number of sewage and wastewater from industrial families were discharged into the river, it was found that the fish caught in the river actually had cancer, and it was Niagara Falls on the border between the United States and Canada. Environmental protection in the United States is already a very high requirement. This happens from time to time, not to mention the water pollution in China.

The mercury in seafood consumers is 8~ 14 times that of vegetarians. Mercury is a toxic substance, which exists in large quantities in fish and shellfish. The ancients committed suicide by swallowing mercury. In recent years, the medical community has found that mercury has no physiological function in our body, only toxicity. People who often eat fish and seafood have very high mercury content in their bodies, which easily affects the central nervous system, digestive system and kidneys, and also has certain effects on the respiratory system, skin, blood and eyes. Especially pregnant women need to pay attention!

In modern times, due to environmental pollution (especially the ocean), the fish we eat every day has become an important way for mercury to invade the body; Fish itself contains a lot of very beneficial unsaturated fat, but its benefits of strengthening cardiovascular system are all destroyed by mercury poisoning. Therefore, eating a lot of fish and seafood has become harmful to health!
