Tips

1

Moderate alcohol consumption (about 20g per day) may reduce the risk of cardiovascular disease, but excessive intake has the opposite effect. Red wine's polyphenols are particularly noteworthy.

2

Alcohol is metabolized in the body into acetaldehyde, a toxic substance that causes hangovers. To reduce liver burden, hydration before and after drinking is important.

3

Women have lower alcohol dehydrogenase activity than men, so the same amount can lead to higher blood alcohol levels. Special caution is needed during pregnancy or breastfeeding.

4

Alcohol contains about 7 calories per gram, which can contribute to weight gain like sugar or fat. For example, a 350ml beer has about 140 calories, and 180ml sake has about 200 calories.

5

Alcohol metabolism takes about 1 hour per kg of body weight, and individual differences are significant. When empty or fatigued, metabolism slows, so reduce drinking amounts.

FAQ

  • QUESTION 1

    What is pure alcohol?

    Pure alcohol refers to the ethyl alcohol (ethanol) content in beverages. It is calculated by multiplying the alcohol content by the volume and 0.8 (the specific gravity of ethanol).

  • QUESTION 2

    What are the guidelines for moderate drinking?

    According to WHO guidelines, adult males should consume no more than 20g per day, and adult females no more than 10g per day. This is a guideline to avoid adverse health effects.

  • QUESTION 3

    How long does it take for alcohol to leave the body?

    Generally, it takes about 1 hour to metabolize 1g of pure alcohol. Individual differences are significant and depend on body weight and liver function.

  • QUESTION 4

    Why are alcohol-free periods necessary?

    They help rest the liver, improve sleep quality, and prevent alcohol dependence. Having 2 or more alcohol-free days per week is recommended.

  • QUESTION 5

    Which is healthier, beer or sake?

    The total amount consumed is more important than the type. However, sake has a higher alcohol content, so the same volume can lead to higher intake.

  • QUESTION 6

    What are alcohol-drug interactions?

    Combining most medications with alcohol is dangerous. Especially sleeping pills, anti-anxiety drugs, and antibiotics can cause serious side effects.

  • QUESTION 7

    How to prevent hangovers?

    Eat before drinking, stay well-hydrated, pace your drinking, and take B vitamins. These methods are effective.

  • QUESTION 8

    Does higher alcohol content make you drunk faster?

    Yes. The same volume with higher alcohol content leads to higher pure alcohol intake and makes you drunk faster.

  • QUESTION 9

    What are gender differences in alcohol metabolism?

    Women have lower body water content than men and lower alcohol dehydrogenase activity, so the same amount can lead to higher blood alcohol levels.

  • QUESTION 10

    What is alcohol's nutritional value?

    Alcohol contains 7 calories per gram, similar to sugar or fat. It also has an appetite-stimulating effect, so caution is needed.

  • QUESTION 11

    Is red wine really healthy?

    Red wine contains polyphenols (resveratrol) with antioxidant properties, but these benefits are limited to moderate consumption only.

  • QUESTION 12

    What are signs of alcohol dependence?

    Inability to control drinking, inability to sleep without alcohol, withdrawal symptoms like tremors or sweating require professional consultation.

  • QUESTION 13

    What is the mechanism of alcohol metabolism?

    Alcohol is mainly metabolized in the liver. First, it is converted to acetaldehyde by alcohol dehydrogenase (ADH), then to acetic acid by aldehyde dehydrogenase (ALDH), and finally to water and carbon dioxide.

  • QUESTION 14

    What are the effects of moderate drinking?

    Moderate drinking has been reported to have benefits such as reduced risk of cardiovascular disease, increased HDL (good) cholesterol, and stress relief. However, these benefits are limited to moderate consumption.

  • QUESTION 15

    What are the effects of excessive drinking?

    Increases risk of liver disease, heart disease, cancer, stroke, and addiction. It also impairs judgment, leading to accidents and injuries.
