The advantages and disadvantages of drinking coffee. Drinking coffee in moderation is best

Many people say that drinking coffee hurts the stomach, causes nervousness and palpitations, and that their hands tremble after drinking coffee, so they dare not try it. However, it also has many unknown benefits. As long as you know how to drink it at the right time and in the right amount, you can fully realize the benefits of coffee.

Coffee ingredients

Coffee beans themselves contain B vitamins and niacin, and the content of roasted coffee beans is higher than that of raw coffee beans. They also contain free fatty acids, caffeine, and tannins. So coffee itself has calories, but not much. The main calories come from the creamer and sugar you add when drinking coffee.

Benefits of Caffeine

1. Caffeine can stimulate the central nervous system and muscles, so it can boost spirits, improve thinking and memory, and restore muscle fatigue.

2. It acts on the cardiovascular system to improve heart function, dilate blood vessels and promote blood circulation.

3. For the gastrointestinal system, it can help digestion and help break down fat.

4. Recently, a new study in the United States showed that drinking coffee can enhance sexual desire because coffee can improve blood circulation, speed up heart rate, and stimulate the activity of the nervous system. Therefore, people who drink coffee regularly have more active sex lives than those who do not drink coffee regularly. Not only that, it can also reduce the risk of impotence.

5. Coffee can protect laboratory mice from radiation damage, and may have the same effect on humans. Researchers at the Indian Atomic Research Center found that 70% of laboratory mice injected with caffeine were still alive 25 days after receiving a high dose of radiation that would normally be lethal, while all mice that did not receive the injection died.

6. Drinking a cup of coffee every morning may reduce your risk of Parkinson's disease. Experiments on mice at Massachusetts General Hospital found that caffeine can maintain levels of dopamine in the brain, a neurotransmitter that allows brain cells to communicate. Parkinson's disease is associated with a lack of dopamine in the brain.

Harmful effects of caffeine

1. Aggravate high blood pressure

Because of its analgesic effect, caffeine is often combined with other simple analgesics. However, long-term and large-scale use will only make your condition worse if you already have high blood pressure. Caffeine alone can raise blood pressure, and if emotional tension is added, it will have a dangerous multiplication effect. Therefore, people at risk of high blood pressure should especially avoid drinking caffeinated beverages when they are under great work pressure. Some people who have the habit of drinking coffee all year round think that they are immune to the effects of caffeine, but this is not the case. A study shows that after drinking a cup of coffee, blood pressure can rise for up to 12 hours.

2. Induce osteoporosis

Caffeine itself has a good diuretic effect. If you drink a lot of coffee for a long time, it will easily cause bone loss, which will have an adverse effect on the preservation of bone mass. For women, it may increase the threat of osteoporosis. But the premise is that you don’t have enough calcium in your daily food, or you don’t exercise often, and women after menopause will lose calcium due to lack of estrogen. These conditions plus a lot of caffeine may pose a threat to bones. If you can enjoy it in a reasonable amount, you can still avoid giving up because of fear.
