At the same time, some studies have come to a conclusion similar to Nature: a small amount of drinking will increase the incidence of 60 diseases. Epidemiological evidence shows that studies carried out around the world since 1970 have proved that a small amount of drinking (65438+ 0 ~ 2 cups a day) can reduce the risk of coronary heart disease in elderly men and women by about 20% ~ 30%, but even a small amount of drinking will increase.
A small amount of drinking will have a bad effect on the brain. A study published by American scientists also shows that whether it is light or moderate drinking, it will inevitably have a negative impact on these people's brains. People who drink between 1 ~ 6 glasses a week are considered as light drinkers, while moderate drinkers drink more than 7 glasses a week. According to the results of magnetic resonance imaging, light and moderate drinkers do cause brain atrophy after drinking. The study also found that this situation does not distinguish between men and women, nor between races.
No matter how much asthma attack it can induce, some data show that it is harmful to asthma patients, no matter how much alcohol they drink or how high or low their alcohol level is. This is because alcohol can not only cause allergic diseases, but also induce asthma attacks.
A small amount of drinking will also vary from person to person.
It can be seen that a small amount of drinking may be beneficial to some diseases (such as cardiovascular diseases), but it will also increase the chances of suffering from other diseases. Experts tell us that when deciding whether to drink alcohol for health, we should weigh the pros and cons according to our own situation and avoid blind obedience.
A general view is that whether a person can drink or not and how much he drinks every day should be decided by a doctor, because everyone's physical condition is different.
Judging from the current research, opinions on alcohol restriction are not uniform, but some institutions and researchers have put forward some standards. On June 5438+February, 2003, the International Wine Policy Center in Washington, D.C. determined that the standard drinking amount of different countries was 8 grams per day for British people and 14 grams per day for Americans, but Japanese people could drink 19.75 grams, and confirmed that a small amount of drinking 1 2 times per day could reduce the incidence of cardiovascular diseases by 20% ~ 30%.
Professor Li Youming, who has been engaged in the research of alcoholic fatty liver for a long time, has found the incidence law of alcoholic fatty liver after years of epidemiological investigation and research, and recently formulated the "safe limit" for "drinking a little". They designed a simple formula to calculate alcohol intake, that is, alcohol consumption (grams) = alcohol consumption (milliliters) × alcohol concentration (%) × 0.8. For example, if you drink 100 ml of 52-degree (52%) liquor at a time, the alcohol content = 100 ml × 52% × 0.8 = 4 1.6 g of alcohol. Drinking more than 40 grams a day for more than five years in a row, that is, accumulating more than 73 kilograms, 48% people will suffer from alcoholic liver disease to varying degrees.
Professor Li Youming pointed out that "safe dose" is relative, because different people have different sensitivities to alcohol, and individuals vary greatly. Their investigation also found that no matter liquor, wine, beer or any other alcoholic beverage, as long as the total amount is too large, it is harmful to the liver. Long-term drinking is more harmful to the liver than occasional heavy drinking. Drinking every day is more harmful than intermittent drinking, and drinking in large quantities is more risky than drinking several times a day.
