With the improvement of economic level, people are not satisfied with eating enough, but should eat well and eat nutrition. This is of course a good thing, and it is also a successful embodiment of the efforts of nutritionists from all walks of life for many years.

However, it is precisely because of everyone's pursuit of health and nutrition that many wrong health care methods have become the mainstream and even praised by young people. On the one hand, it is the lack of knowledge, on the other hand, it is the false and exaggerated propaganda of merchants.

For example, some merchants claim that drinking fruit and vegetable juice for a week in a row can expel toxins and stools from the body, and even have many magical effects such as losing weight, lowering blood pressure and lowering blood fat.

So today, the nutritionist who broke the nutrition class will talk to you: Can drinking fruit and vegetable juice for a week detoxify and lose weight? Rumor: Beware of diarrhea and malnutrition.

First of all, what is the so-called "toxin"? Some people think that defecation is toxic, bad breath is toxic, sweat is toxic, and bacteria, pesticide residues and air pollution in food are "toxic".

It is true that bacteria and pesticide residues will have adverse effects on the body, but it does not mean that "toxic" is "harmful". There are dozens and hundreds of kinds of bacteria in human mouth. These bacteria also participate in the normal physiological metabolism of the body. Without them, people will get sick.

Let's talk about it. If you just drink fruit and vegetable juice, will your body get better?

In vegetables and fruits, the main nutrients are water, dietary fiber, minerals, vitamins and a small amount of protein, which are needed by human body. But in addition, the body needs fat, carbohydrates and a variety of amino acids.

The long-term lack of any kind of nutrients in the body will directly affect the progress of some physiological reactions, thus further reducing the body's resistance and making it easy to get sick.

What's more, if you only drink fruit and vegetable juice with insufficient calories and fat and protein, you will be prone to malnutrition, with symptoms such as hypoglycemia, muscle aches, fatigue, dizziness and nausea.

Some people will have diarrhea after drinking fruit and vegetable juice, thinking that this is "clearing the stool", which is actually wrong. Some varieties of fruit and vegetable juice contain a lot of fructose, and people who are intolerant of fructose will cause diarrhea.

Whether you are losing weight or keeping fit, you should match the food correctly. Dieting and eating only certain foods are not reasonable choices.
