Drinking too much coffee makes women infertile.

Coffee is the largest consumption beverage in the world. In recent years, the number of people who drink coffee in China is increasing day by day. Many women entrepreneurs, businessmen, public relations people and trendy women are also keen on drinking coffee because of their work and social needs. However, relevant people in the medical profession believe that women should not drink too much coffee. So what are the effects of eating more coffee on women's health?

The researchers found that women who drank one cup of coffee a day were more likely to suffer from infertility than those who did not drink coffee. Experts have investigated 104 women who have the habit of drinking coffee, of which about 50 are not easy to get pregnant. Some fertility experts believe that this is a small-scale study that cannot finally confirm the special effect of coffee on fertility. However, the researchers stressed that if there is no medical explanation for the cause of infertility, it should be considered that infertility is related to caffeine.

Doctors at the School of Public Health at Boston University studied 858 women who first had a heart attack at the age of 45 to 69 and 858 women who had never had a heart attack for four years. Drinking five or more cups of coffee a day increased women's risk of heart attack by 70 percent, and the risk increased with the amount of coffee they drank.

Researchers at the University of California in the United States investigated 980 50-98-year-old women and found that elderly women who drank more than two cups of coffee a day without milk for a long time, regardless of age and obesity, the bone mineral density of the hip and spine decreased, and the extent of the decrease was related to the duration of the habit and the amount of consumption. Because caffeine can be combined with free calcium in the human body and excreted through urine. The decrease of free calcium will inevitably lead to the decomposition of bound calcium, which leads to osteoporosis. 4. Coffee drinking by pregnant women is bad for the fetus.

In the early 1980s, Dr. Colin of the US Food and Drug Administration found that pregnant mice would give birth to malformed mice when they were fed the equivalent of 12 to 24 cups of espresso for adults every day. To this end, the researchers, in the name of the U. S. Food and Drug Administration, warned pregnant women to stop drinking coffee.

Is a disease unique to pregnant women, patients with edema, hypertension and proteinuria, if not timely prevention and treatment, can endanger maternal and fetal safety. Drinking just a few cups of coffee a day can raise blood pressure, according to an Australian study. For this reason, pregnant women should not drink coffee.

Through research and analysis, researchers in Finland and the United States found that both countries are the largest consumers of coffee, resulting in the largest number of people suffering from diabetes in these two countries. Among them, Finns have the largest coffee consumption in the world, and the country has the largest number of people with diabetes in the world. Other Nordic countries also consume a lot of coffee and have a large number of people suffering from diabetes. On the contrary, the Japanese have the lowest coffee consumption in the world and the least people with diabetes. The researchers believe that the caffeine contained in coffee drinks can be precipitated into fetal tissue through the pancreas, especially in the fetal liver and brain, so that postnatal babies may develop diabetes.

In addition, drinking coffee can increase the risk of heart disease and high blood pressure, and lead to addiction in both men and women.
