Effect of Coffee Encyclopedia Coffee on Human body

The caffeine in coffee is a white powder, odorless, slightly bitter nitrogen compound, which is prescribed by the British Pharmaceutical Code at a dose of 0.65 grams per day. Caffeine and its metabolites can be excreted from the body in the form of urination within 24 hours. it can affect the brain, heart, blood vessels, intestines and stomach, kidneys and other parts of the body. An appropriate amount of caffeine will stimulate the cerebral cortex, promote sensory memory, and emotional activity. let the excess sodium ions in the function of the heart muscle out of the body.

Caffeine is a mild stimulant to the central nervous system and has the following functions:

1. It can stimulate nerves appropriately, eliminate fatigue and restore vitality.

2. stimulate the cerebral cortex to make the thinking power exuberant.

3. Stimulate the intestines and stomach, increase intestinal peristalsis and promote digestion, so it is a rapid laxative.

4. Promote fat decomposition, stimulate physical fitness, increase exercise ability and sustain energy.

5. increasing the metabolic rate of the new city is beneficial to control the weight and help to lose weight.

6. it can relax the bronchial muscles, so drink some coffee during asthma to relieve asthma.

7. improve renal function and play a diuretic role.

8. stimulate the myocardium, increase the work of the heart and the consumption of oxygen, and make the heart beat faster.

Study Bian:

heart disease

In 1980, a study found that men who drank more than five cups of coffee a day for long periods of time were more likely to suffer from heart disease. But a recent study found that women who drank less than five cups of coffee a day did not have an increased risk of heart disease, and women who drank more than six cups a day did not seem to have an increased risk of heart attack.

cancer

A 1981 Harvard University report found that drinking a lot of coffee can lead to pancreatic cancer, but at least seven important studies have since failed to confirm this, so the researchers withdrew this conclusion. Several other studies have failed to prove a link between coffee drinking and breast cancer.

The Boston University study found that drinking a lot of coffee seemed to reduce the risk of bowel or rectal cancer, with people who drank at least five cups of coffee a day 40% less likely to develop colon cancer than those who did not drink coffee.

Reproductive health

About 70% of pregnant women drink coffee, and most doctors and researchers now agree that it is safe for pregnant women to drink baristas. Studies have shown that daily consumption of caffeine up to 30mg (about 3 cups of coffee) will not have a negative impact on fertility, but in order to avoid any problems, researchers and doctors advise pregnant women not to drink coffee during this period.

osteoporosis

Osteoporosis is not endemic to women, but most of it occurs in women. The factors causing osteoporosis include calcium and protein intake, smoking, exercise habits, age, weight and so on. In order to gain insight into the relationship between caffeine intake and osteoporosis, researchers must carefully grasp each variable.

A 1994 Barrett Connor study found that caffeine intake affected bone mineral density reduction only in women who were limited to one glass of milk a day as adults. According to this study and common sense, coffee can only indirectly cause calcium deficiency. For example, some women use her instead of calcium-rich drinks.

In 1995, Barger_Lux and Heaney concluded from an analysis of data from 190 women: "one glass of milk provides enough calcium to offset the negative effects of eight cups of caffeinated coffee." This highlights the fact that caffeine is not a high risk factor for osteoporosis, but that inadequate calcium intake is the main cause, and that secondary factors, such as caffeine, have an effect.

Control weight

It showed that two and a half hours after drinking coffee, the effect of caffeine was still there. Another study found that 100mg caffeine increases metabolism by 3% to 4 percent; the more caffeine is absorbed, the greater the increase, and the faster calories are consumed if you exercise at the same time.

Conclusion:

In recent years, most studies on coffee and health have shown that healthy people who drink the right amount of coffee are harmless to their health. For pregnant women, they want to be risk-free, so coffee is not recommended.

"everything in moderation" follows the same truth, so that women can also enjoy caffeinated food and drinks, but will not endanger their health.
