I talked about the advantages of drinking so much coffee before, but everything has its advantages and disadvantages. Today, let's talk about the harm of drinking too much coffee.

1, coffee contains esters, oils and caffeine can stimulate the gastric mucosa, and can promote the secretion of gastric acid, if drinking too much coffee will cause stomachache.

2. Caffeine constricts the microvessels of the eye, reducing the amount of nutrients that enter the eye cells and reducing the rate at which the eye removes waste.

3. If a woman drinks too much coffee during pregnancy, the birth weight of the baby is lower, and regular coffee drinking will significantly reduce the chance of pregnancy.

4. Caffeine will affect the function of the kidney and can play a role in diuresis, so if you drink too much caffeine, it will affect the kidney to a certain extent.

5, coffee also has the role of regulating the brain center, but also has a direct effect on the heart, if you drink too much will make the heartbeat faster.

6. Drinking coffee for a long time may also induce osteoporosis. The impact on women in particular is more obvious. The National Health Service (NHS) advises pregnant women not to consume more than 200mg of caffeine a day, otherwise it will increase the risk of miscarriage. 200 milligrams of caffeine, equivalent to two mugs of coffee.

7. If you drink milk coffee with high-fat snacks, it is very disadvantageous for people with diabetes and obesity.

8. Excessive drinking will cause harm to the central nervous system and cardiovascular system.

But if you drink it properly, because caffeine is a xanthine alkaloid, it can stimulate the central nervous system, cardiovascular system, gastric acid secretion and diuresis. It can also boost the spirit, enhance thinking, enhance memory, relieve fatigue, and help digestion and diuresis.

However, while there is a correlation between long-term coffee drinking and reducing the risk of disease, it is not a clear conclusion, and it is not certain how coffee has a positive impact on health. Rigorous clinical trials are needed to explore the clear health benefits of coffee.

And coffee has never been an essential nutrient in dietary guidelines, and everyone's reaction to coffee is not exactly the same. If you are used to drinking coffee and are within the range of healthy doses, continue to drink it; if you are not used to drinking coffee, you do not have to change your habit.
