But many health experts do not recommend this approach to improve health. They say there is little scientific evidence that these dietary restrictions can remove harmful substances from the body or make it healthier.
According to joy Dubost, a spokesman for the society for nutrition and diet and nutritionist, it's a high expectation to see juice detoxification as a quick way to lose weight. She pointed out that if you want to eat a healthier diet, you should eat more fruits and vegetables as well as foods rich in cellulose. Dubost suggested that instead of drinking some health drinks to detoxify, you should consult a nutritionist to make a healthy diet plan, which will bring more long-term benefits to your health and help you lose weight.
In order to help readers distinguish facts from rumours, Du Bost commented on the seven popular ideas about detoxification.
1. Rumor: when the body does not eat solid food for more than 12 hours, it will switch to 'detoxification mode', and the body will start to self repair and eliminate toxins in the body
Fact: in the natural state, our bodies are always removing waste from our bodies. Our body has an existing detoxification system: a system composed of liver, lung, kidney and gastrointestinal tract can remove toxins and harmful substances in the body. "Detoxification mode" is not a physiological process. The body will not switch to the so-called "detoxification mode" because it stops eating solid food. Dubost said she had no idea what the sales people were talking about because they couldn't even name the toxins.
2. Rumor: juice is lack of cellulose, without which the digestive system can rest, and the energy in the body will be stored for detoxification
Fact: at present, no research supports the idea that the digestive system needs rest. Only after the operation, the digestive system needs rest, but you don't need to keep healthy in this way. The cellulose contained in juice is very limited. In fact, it is a disadvantage of juice detoxification. Cellulose can maintain the normal function of gastrointestinal tract, ensure the regularity of gastrointestinal peristalsis, and increase the sense of fullness. In addition, adding fiber to your diet can help reduce the risk of heart disease and cancer.
Colorful juice is not as nutritious as you think Rumor: some people will have headache, dizziness, fatigue and depression in the process of 'juice detoxification', which is a normal phenomenon and a manifestation of the body's detoxification
Fact: the above symptoms do appear in the process of 'juice detoxification', but it is not the body's detoxification. On the contrary, it is a sign of no normal eating, indicating that the body lacks some nutrients at this time. Another potential hazard of juice detoxification is insufficient energy intake. 'open your legs' is the long-term way to lose weight.
4. Myth: detoxification can help people correct unhealthy eating habits
Fact: correcting unhealthy eating habits is a highly dependent and conscious process. Some people are trying to detoxify only in response to their psychological needs, not physical needs. They think detoxification can help them form healthy eating habits psychologically and physiologically. Dubost said she understood when people she consulted had similar ideas, but she would try to limit the time they spent detoxifying. 'there are many healthier ways to help lose weight. 'she said.
5. Rumor: detoxification will promote metabolism in the body
Fact: there is no scientific basis for this statement. If people are hungry, they will consume energy and nutrients stored in the body, which will slow down the metabolism of the body.
6. Rumor: detoxification can make people think clearly and concentrate
Fact: 'I don't know where this contrary statement comes from. 'said Dubost. The operation of the brain requires the participation of glucose. In the detoxification diet, people can get some glucose from juice or maple syrup, but it is not enough to make the brain work at the best state. In addition, people may have headache or fatigue during detoxification, which will affect their thinking ability.
7. Rumor: detoxification can reduce weight quickly
Fact: Dubost admits that people may lose weight after the juice has been detoxified for some time. 'but it's all water and muscle loss, and over time, some people may even lose bone. 'she said. And it's not a long-term way to lose weight: once people stop detoxification and resume eating, their weight will soon pick up.
