Coffee has a unique flavor. Many people like to enjoy life by drinking a cup of coffee in their spare time. However, some ingredients in coffee can cause harm to the body, so many people love and fear coffee. What are the specific harms of coffee? What can we do to ensure that coffee and health go hand in hand? The four major hazards of coffee1. It can easily lead to infertility Experts conducted a survey of more than 100 women who like to drink coffee and found that about 50% of them are not easy to conceive. Coffee contains a lot of caffeine, which can cause the special guide cells on the inner wall of the fallopian tube to lose vitality, inhibit the normal contraction of the fallopian tube, and thus affect the smooth entry of the egg into the uterus. 2. Increased risk of myocardial infarction The caffeine in coffee can excite the central nervous system and can be considered a strong drug. In fact, caffeine belongs to the purine class of drugs, which is the same as the ingredient called theophylline in tea. It can directly act on the myocardium and increase the contraction rate, so it is generally used as an emergency drug for the treatment of heart disease. 3. Causes high blood pressure Regardless of whether you are a patient with hypertension or not, consuming caffeine will cause a brief but dramatic increase in blood pressure. The reason for this is still uncertain, but some researchers believe that caffeine can block a hormone that helps arteries dilate; another school of thought is that caffeine will promote the secretion of more adrenaline in the body, thereby causing blood pressure to rise. 4. Induce osteoporosis Caffeine can combine with free calcium in the human body and be excreted through urine. The reduction of free calcium will inevitably lead to the decomposition of bound calcium, thus leading to osteoporosis. Therefore, if you drink more than 2 cups of coffee a day for a long time, your bone density will decrease regardless of your age or obesity level, and the degree of decrease is related to the duration of the habit and the amount of drinking. Learn these 4 tips to drink coffee with confidence1. Don’t drink coffee in the morning: When you just wake up, your body will secrete the hormone cortisol, which makes you clear-headed. Drinking coffee at this time will make your body abnormally excited, leading to headaches and palpitations. Especially drinking coffee on an empty stomach will stimulate the esophageal sphincter and there is a risk of acid reflux. 2. Do not drink more than 3 cups a day: Adults should not drink more than 400 mg of coffee a day. Excessive drinking will not only excite the nerves, but also cause a large loss of vitamins in the body due to diuresis. For pregnant women, because the decomposition of caffeine is slow, it is best not to drink more than one cup a day or drink coffee with a lower concentration. 3. Drink within half an hour and rinse your mouth after 15 minutes: Coffee contains tannic acid, which can combine with proteins in the mouth and cause yellowing of teeth. Therefore, we should try to reduce the time that coffee is in contact with teeth. Do not rinse your mouth immediately after drinking, otherwise the teeth that have become weakly acidic due to drinking coffee will be corroded. 4. Women with anemia or menopause should not drink caffeine: the chlorogenic acid in caffeine will hinder the body's absorption of iron, so anemic patients and women with menopause should not drink it. In addition, people who take anti-inflammatory drugs such as aspirin should also be aware that the ephedrine contained in anti-inflammatory drugs will put a burden on the heart when it meets caffeine. |
