Efficacy and function of garlic;

1, anticancer

Foreign studies have found that sulfur-containing compounds in garlic can promote the production of an enzyme or a substance called allicin in the intestine, and eliminate the risk of intestinal tumors caused by intestinal substances by enhancing the body's immune ability, blocking the formation of lipid peroxidation and anti-mutation. However, it is still uncertain how many such enzymes need to be produced to effectively play the anti-tumor role of garlic.

2. Anti-aging effect

Some components in garlic have antioxidant and anti-aging properties similar to those of vitamin E and vitamin C.

3. Anti-fatigue effect

Some people have found that pork is one of the foods rich in vitamin B 1, and the combination of vitamin B 1 and allicin contained in garlic can play a very good role in eliminating fatigue and restoring physical strength.

Extended data:

Five kinds of people should not eat garlic raw:

1, patients with eye diseases

The ancients said, "All garlic diseases need only one look." Eating garlic in large quantities for a long time is harmful to the eyes. Ji Kang said in "On Health Preservation" that "spicy meat hurts the eyes", while garlic is the most spicy, clear and easy to hurt the eyes. So be careful not to eat too much garlic, especially people with eye diseases, and avoid spicy food during treatment.

2. Weak heat

The ancients thought that eating more garlic would dissipate people's qi and blood, and Materia Medica from the New recorded that "garlic is pungent and toxic, causing phlegm burning, dispersing qi and consuming blood, and it is not suitable for those who are weak and hot to touch their lips". Therefore, people with poor health and weak qi and blood should pay attention.

3. Patients with liver disease

Many people use garlic to prevent hepatitis, and even some people still eat garlic every day after suffering from hepatitis. This is all wrong. "Compendium of Materia Medica" records that garlic "hurts the liver and eyes for a long time". Garlic is hot and can help fire. It's pungent. If people with liver fire eat it, it will be more prosperous, and it will definitely hurt after a long time.

4. Patients with diarrhea due to spleen deficiency

Raw garlic is very exciting. Eating less in peacetime can promote digestion. However, if you eat garlic when suffering from non-bacterial enteritis or diarrhea, strong stimulation will aggravate the congestion and edema of intestinal mucosa, promote exudation and aggravate the condition.

5, seriously ill patients eat carefully.

Garlic hair, so-called hair, refers to foods that are particularly prone to induce certain diseases or aggravate diseases that have already occurred. Eating spicy food such as garlic and pepper is likely to have obvious side effects for people who are seriously ill or taking drugs, which will not only cause old diseases, but also make drugs ineffective or have a chain reaction with drugs, affecting their health.
