Health rules for drinking coffee

Caffeine prolongs the time it takes to thank caffeine in the body. In general, the metabolism of caffeine in normal adults takes 2 hours, but in patients with liver disease or liver insufficiency, the metabolism of caffeine may take 4-5 hours, so patients with liver disease must be careful when drinking coffee, it is best not to drink it after dusk, so as not to affect sleep due to long metabolic time, and it is best not to exceed 1 cup a day.

Patients with digestive system diseases

I believe that people who often have stomachaches and stomach ailments have an experience, that is, doctors will tell them not to eat irritating foods, including wine, chili peppers, coffee, tea and carbonated drinks.

Coffee is among them because the tannic acid stimulates gastric acid secretion, which must be avoided if it is in the acute stage of digestive disease. After returning to health, if you drink coffee occasionally, it is best to use it after meals to avoid drinking coffee on an empty stomach.

Pregnant woman

Many women pay special attention to all foods they eat since they are pregnant, and drinks containing caffeine are also taboo. This is mainly due to the slow metabolism of caffeine in pregnant women, the caffeine stays in the body for longer, and the fetus in the belly will not be able to remove caffeine from the blood through metabolism until eight or nine months.

Child

Due to the incomplete development of children's liver and kidney and poor detoxification ability, the half-life of caffeine metabolism will be prolonged, so generally speaking, children under the age of 12 need to ban caffeine intake. Even people in Europe and the United States who drink coffee as boiled water all day have very strict restrictions on children's drinking coffee.
