Scientific recommendations for daily black coffee intake

Coffee is one of the world's most popular beverages, and many people drink one or more cups of coffee every day to keep themselves awake. However, there are different opinions and recommendations on how much black coffee you should consume each day. This article will explore the scientific perspective on the daily black coffee intake recommendations.

1. Healthy adults

For healthy adults, drinking black coffee in moderation is safe and beneficial to health. According to research by authoritative organizations such as the American Heart Association (AHA) and the European Food Safety Authority (EFSA), there are no obvious negative effects of consuming less than 400 mg of caffeine per day (about 4 cups of 8 ounces).

However, not everyone can tolerate the same doses of caffeine. Individual differences, medical conditions, and other medications or supplements may affect a person's sensitivity and tolerance to caffeine. Therefore, it is best to consult a doctor or nutritionist to determine the appropriate amount of caffeine for you.

2. Pregnant and lactating women

Pregnant and breastfeeding women need to pay special attention to their black coffee intake. According to the American College of Obstetrics and Gynecology (ACOG), it is safe to consume less than 200 mg (about 2 cups of 8 ounces) of caffeine per day during pregnancy. High doses of caffeine intake are associated with adverse outcomes such as miscarriage, premature birth, and low birth weight.

During breastfeeding, although there is no definitive data to suggest that high doses of black coffee will have a negative impact on the transfer of breast milk to the baby, to be on the safe side, it is recommended to control daily intake to less than 200 mg.

3. Teenagers

Teenagers are often more susceptible to the effects of stimulants in food and drinks than adults. According to a report released by the European Food Safety Authority (EFSA), adolescents aged 12-18 should limit their caffeine intake to less than 100 mg (about 1 cup of 8 ounces) per day. Excessive caffeine intake may cause sleep disorders, anxiety and rapid heartbeat.

In addition, teenagers are in the growth and development stage and need adequate nutrition to support physical development. Drinking too much coffee may suppress appetite and affect normal eating habits.

4. People who are sensitive to caffeine

Some people are very sensitive to caffeine and may experience uncomfortable symptoms even in small doses. These include individuals who are prone to reactions such as palpitations, insomnia, anxiety, or stomach upset. For these people, it is best to avoid or limit black coffee intake.

5. Additional Notes

In addition to your daily black coffee intake, there are some additional considerations to keep in mind:

• Hydration: When drinking black coffee, make sure you also drink enough water to keep your body levels balanced.
• Additives: When enjoying delicious black coffee, try to avoid adding too much sugar, creamer or other high-calorie ingredients.
• Time control: Avoid drinking caffeinated beverages at night to avoid affecting sleep quality.

in conclusion

Overall, moderate intake of black coffee is safe and beneficial for most healthy adults. However, everyone has different tolerance to caffeine, and individual differences and physical conditions should be considered when determining your appropriate intake. Pregnant women, breastfeeding women, adolescents, and people who are sensitive to caffeine need to pay special attention to their black coffee intake. In addition, when enjoying delicious black coffee, pay attention to additional matters such as water replenishment, use of additives, and time control.

The most important thing is to maintain moderation and adjust your daily black coffee intake according to your personal circumstances to ensure you are getting the best effects from it without any negative effects.
