Coffee and tea: benefit or harm

Coffee and tea are wonderful tonic drinks .
Coffee and tea are not the basic foods needed by the female body, but coffee beans and tea leaves are available in almost every family. Both of these drinks are very tasty, they have a toning effect. Thus, coffee and tea with the correct dosage are useful, but when they are abused their effect on the health of a woman can be sharply negative.

How does coffee and tea work ?

Ground coffee and tea leaves are poured with boiling water, in which, apart from other constituents, alkaloids, nitrogen-containing organic compounds, are also dissolved, large doses of which can be toxic. Alkaloids act on the brain and spinal cord. Coffee and tea contain caffeine alkaloid. Previously it was assumed that tea contains a specific alkaloid of theine, but scientists in recent years have determined that this is not so. Coffee contains 1.2 - 1.4% caffeine, while in decaffeinated coffee, it is at most 0.1%. In tea, much more caffeine (up to about 5%). However, the tea caffeine is bound to tannin, so the tea caffeine from the digestive tract is resorbed much more slowly. Hence, stimulating and toning tea begins to act after coffee, but its effect is more positive. Caffeine coffee usually has a stimulating effect on the cardiovascular system, and tea caffeine - on the brain and the central nervous system of women.

Is coffee and tea harmful?

A large amount of caffeine is toxic, and the lethal dose is ten grams (which corresponds to one hundred cups of coffee drunk one by one). In a woman's body, caffeine does not accumulate, half the digested caffeine is split in 3-5 hours, and after 24 hours, only a small amount remains in the body. According to the latest research data, caffeine does not contribute to the development of coronary heart disease (six cups of coffee a day) or other health problems, such as diabetes, cirrhosis, stroke and cancer. Gout or gastric ulcer is also not a result of the abuse of coffee or tea, but is the result of malnutrition, smoking, and alcohol abuse.

Sometimes the stomach gets angry

Caffeine and tannins of coffee and tea stimulate the secretion of the gastric mucosa. Therefore, in sensitive people after coffee sometimes begins to ache a stomach. If you do not want to give up a cup of morning coffee, then drink it without caffeine. It has a milder effect on the stomach.

Better short brewing

Coffee-express for the stomach is much more useful than usual, as coffee is passed through the filter. When making coffee express in a special apparatus through ground coffee, water vapor under pressure passes under pressure for several seconds, and tannins and bitterness simply do not have time to dissolve. By this principle, tea is spiked and sparing the stomach. Tea brewing is insisted no more than three minutes, because during this time caffeine dissolves, but not tannins. And if tea does not seem too strong, then it is necessary to take a large amount of tea leaves and pour boiling water for a short time.

Coffee and tea during pregnancy

The liver of the fetus splits caffeine (got with the blood of the mother) much more slowly than the liver of an adult. At the present time it is not yet clear whether this harms the future child. However, it is proved, if the future mother abuses coffee or tea (drinks more than eight cups a day), then the probability of congenital anomalies of the child significantly increases.
