There was one in Shanghai a few years ago.

A female patient whose small intestine was completely removed for a week,

I can't get nutrition through diet all my life.

Therefore, only a full set of synthetic nutrient solution can be injected intravenously for a long time.

Nutrient solution company fully sponsored her to become its own brand spokesperson.

Exempted her from the cost of tens of thousands of survival nutrient solution every year.

Surprisingly, a few years later, she was able to get pregnant and have children, and she was still alive and well.

Because of this, the company is also famous in the field of parenteral nutrition.

Some students think. Can we stop eating?

Indeed, according to the current technology, it can meet the needs of most kinds of minerals, inorganic salts, three nutrients, vitamins and so on.

However, many elderly people cannot digest and absorb food through normal channels due to cancer, surgery and other reasons.

You can only choose different nutrition for the rest of your life, that is, intravenous injection of total nutrient solution every day.

Strangely, these old people died soon.

The reason is not that the nutrient solution is unscientific and incomplete.

The reason is that the function of the intestine is not limited to digesting and absorbing food.

His second important function is to stimulate immune cells in the body and maintain certain immunity.

Intestine is the largest immune organ of human body, and the microorganisms in it weigh several kilograms! ! !

These creatures are good, neutral and bad.

Harmful microorganisms struggle with normal immune cells every day.

The body also uses this to maintain a certain immunity.

If you can't eat normally for a long time,

Intestines will contract, microorganisms will die quickly, and the collective will not get effective immune stimulation.

Even part of the intestinal wall is damaged, which makes microorganisms spread from the body to the blood and all parts of the province.

It leads to all kinds of serious complications, and because of the extremely low immunity, even under the action of antibiotics, there is nothing you can do over time.

Therefore, people should eat all kinds of food from all aspects of life.

Because of the singleness of food nutrients, it is necessary to eat all kinds of foods to meet all nutritional needs. So as not to cause a lack of certain nutrients and cause physical disaster.

At present, science is not developed enough, and some phytochemicals and some nutrients that do exist in some things and are very beneficial to the human body have not been discovered.

So, eat as wide as possible!

I am an undergraduate majoring in medical nutrition, and my literary talent is poor. Please forgive me.
