The harm of drinking too much coffee

Coffee is a fashionable drink in modern life. Its main component is caffeine that excites the brain. In addition, it also contains fat, protein, carbohydrates, inorganic salts and vitamins. Most instant coffee contains 3% ~ 4% caffeine, and a cup of brewed coffee contains about 150 mg caffeine. The advantage of drinking coffee is to lift the spirit, but drinking coffee too much will cause disease.

Induce heart disease

American medical scientists have found that a person who drinks five or more cups of coffee a day is twice as likely to suffer from heart disease as a non-drinker, and the longer he indulges in coffee, the more he drinks, the greater the possibility of heart disease. Through the investigation of 858 people aged 45-69 who suffered from myocardial infarction for the first time and the same number of people who have never suffered from myocardial infarction, it is proved that people who drink more than 5 cups of coffee every day have a 70% increased risk of illness.

Lead to osteoporosis

Caffeine can combine with free calcium in human body and be excreted with urine. The decrease of free calcium will inevitably lead to the decomposition of bound calcium, which will lead to osteoporosis. It is found that people who drink more than two cups of coffee a day for a long time, regardless of age and obesity, will reduce the bone density of buttocks and spine, and the degree of reduction is related to the duration of habits and the amount of drinking.

It may be related to diabetes.

The study found that Finland and the United States consume the most coffee and have the largest number of people with diabetes. On the contrary, Japan consumes less coffee and has fewer diabetics. In addition, the study also found that caffeine can be precipitated into fetal tissues (mainly liver and brain) through the pancreas of pregnant women. If pregnant women are addicted to coffee, the chances of developing diabetes after birth will increase.

Drinking is harmful

After alcohol is absorbed, it will affect the functions of gastrointestinal tract, heart, liver, kidney, brain and endocrine organs, leading to the disorder of substance metabolism in the body, and the brain will gradually enter a highly inhibited state from an excited state. Drinking coffee will make the brain highly excited, and the reaction will interfere with brain function, stimulate blood vessel dilation, accelerate blood circulation, and increase the burden on the heart, which is more harmful than drinking alone.
