Nicotine, also known as nicotine, is the key to cigarette addiction, and excessive intake may also lead to toxic reactions. However, American studies have found that a small amount of nicotine does help the body and can help prevent Parkinson's disease, which is common in the elderly. Solanaceae plants such as green pepper and eggplant contain a small amount of nicotine in their daily diet, and eating it twice a week is helpful for prevention.

Solanaceae plants, such as green pepper, colored pepper, pepper, tomato and eggplant, all contain trace amounts of nicotine, which helps to prevent Parkinson's disease. (Photo/excerpt from American Daily Medicine) According to the website of American Medical Daily, a research report published by the University of Washington in the Journal of Neurology pointed out that in the past, relevant surveys found that the proportion of smokers suffering from Parkinson's disease was low, but the influencing factors were not clearly stated; In this study, 490 patients with Parkinson's disease were invited as the experimental group and compared with 644 people in the control group in terms of diet and smoking habits.

In the research results, the general intake of fruits and vegetables will not affect the probability of Parkinson's disease, but it is found that the proportion of patients who consume solanaceae vegetables twice or more a week, especially green peppers and colored peppers, has dropped by 30%.

Nicotine and dopamine in the brain

Parkinson's disease also belongs to the category of dementia, which is a chronic degenerative disease of the central nervous system, because the brain can't produce enough dopamine, leading to various physical activity disorders. Nicotine can * * the central nervous system of the brain and increase the content of dopamine in the brain, so it has a certain effect on preventing Parkinson's disease. However, experts do not advise people to get nicotine from cigarettes, because smoking brings more negative harm.

Green pepper, tomato and eggplant are rich in alkaloids.

Solanaceae plants, such as green pepper, colored pepper, pepper, tomato and eggplant, all contain alkaloids, which can be divided into edible vegetables or medicinal plants according to the alkaloid content. Experts point out that eating solanaceae plants 2-4 times a week is the healthiest way to eat, and the nicotine content in pepper vegetables is not as much as that of cigarettes, so there is no need to worry about the danger of poisoning or addiction if you eat too much.
