In the continuous hazy weather, there have been many anti-fog measures on the Internet. People are now discussing these two days. The topic of “What can you eat to fight haze and eliminate toxins? , Tremella, pig blood, lily and so on. Is it really useful to eat these foods? Did we fall into another misunderstanding?

Pig blood and duck blood are called “rubbers in the body” because they can remove the garbage in the respiratory tract and stomach by adsorption. In other words, it is through the physical role to achieve the effect of removing garbage inside the body, and can only play a role after contact with the body's dirt. To get rid of the dust deposited in the lungs, you have to let the “rubber eraser” meet with the dust, and the food enters the body from the digestive tract. After passing through the gastrointestinal tract, macromolecules are digested and broken down into small molecules and other small molecules in the food. It enters the bloodstream and is then transported to cells throughout the body. The whole process is not associated with the lungs, and naturally it cannot clear the lungs. The "Qingfei Health Products" on the market can only be absorbed through the stomach and intestines. Clearing the lungs is just a gimmick and there is no practical effect. It can be seen that eating pig blood and duck blood have nothing to do with clearing the lungs. At most, it helps clear the dust in the respiratory tract and stomach. In addition, there is no experimental or clinical proof that small molecules that rely on food can remove dust from the lungs, so this rumors of the Internet is only people's imagination.

So, does eating really help the haze?

Although food cannot remove or reduce the impact of dust in the air on the lungs, inhalation of dust from the body can stimulate the body to produce poison. Diets can eat foods that detoxify and clear fire, such as chrysanthemum or honeysuckle and licorice soaked in water, although not Qingfei, but it can clear away heat and detoxify; fungus and white fungus contain colloidal components that can remove dust from the digestive tract; dark green and orange vegetables are rich in carotenoids and can also play a role in lung protection; or cook at home Pear water, the Sydney cut into pieces or slices, add water, cooked and eaten, can play the role of Runfei dry.

At the same time, our resistance will be degraded due to hazy days. To increase the intake of beta-carotene, such as eating more pumpkin, fungus, oranges and other foods, β-carotene can be converted into vitamin A in the body. Antioxidant, improve our resistance. Haze and haze has the most direct and obvious influence on the respiratory tract. Therefore, it is necessary to reduce the consumption of spicy or overheated foods, to avoid damaging the respiratory mucosa, and to lose the natural barrier against pollution particles, especially for those who like to eat hot pots. Be sure to eat less or try not to eat hot pot and keep a light diet.

From this we can see that it is unscientific to use food to achieve a true "pure lung" effect. However, it is still possible to improve our physical condition through eating. It is still useful to eat more foods that increase body resistance.
