Drinking coffee has both advantages and disadvantages. Zhao Shunrong, pharmacist, chairman of Taiwan Province Preventive Health Care Association, said that coffee contains many bioactive compounds, including methylxanthine, such as caffeine, theophylline, theobromine, chlorogenic acid, flavonoids and phenols. It is believed that drinking 1 to 3 cups of coffee every day may promote thinking ability, improve memory, reduce the probability of Parkinson's disease, improve constipation and reduce the suicide rate of patients with depression. Moreover, caffeine and theophylline in coffee can promote blood circulation, metabolism, prevent heart disease, reduce the chance of stroke, promote diuresis and accelerate fat decomposition, increase satiety, temporarily suppress appetite and help lose weight.
Drinking coffee to protect the liver used to be hidden here.
As for drinking coffee to protect the liver, there are many studies. According to the National Health and Nutrition Survey (NHANES), caffeine intake is indeed related to reducing the risk of nonalcoholic fatty liver disease. Moreover, many foreign research results have confirmed that "chlorogenic acid" in coffee has the benefit of protecting liver for hepatitis virus carriers.
However, the more coffee you drink, the better the effect. Pharmacist Zhao Shunrong said that drinking too much coffee is not only ineffective, but also may have other side effects, such as: refreshing yourself may make you unable to sleep when it is time to sleep; Diuresis affects sleep and dry skin; * * * Gastric acid secretion will aggravate symptoms such as gastric ulcer. If you have gastric and duodenal ulcers, you should avoid fasting or drinking coffee.

The biggest disadvantage of drinking too much coffee may be that it will lead to calcium loss and accelerate bone loss.

What is the safe intake of coffee? Moderate drinking of coffee (1, 2 cups of coffee a day) is beneficial to human health, but excessive drinking will cause problems.

The British Food Standards Agency's advice on caffeine intake is that each person should not consume more than 300 mg of caffeine per day.
Drinking coffee with pepper is really a combustion-supporting fat?
Pepper is mainly composed of piperine, and also contains a certain amount of aromatic oil, crude protein, crude fat and soluble nitrogen, which can remove fishy smell and greasy taste, help digestion, promote sweating and improve blood circulation function. The fragrance of pepper can stimulate appetite. Although black pepper can promote sweating and blood circulation, it is not suitable for everyone according to Chinese medicine. Pepper helps to eliminate cold and dampness, but it is not suitable for people with hot constitution. Ordinary people tend to eat too much gastric mucosa. Does coffee with pepper burn fat? Further clinical confirmation and expectation are needed.
The pros and cons of coffee are loss, and the supply should be balanced.
Pharmacist Zhao called for coffee to secrete stomach acid. It is recommended not to drink on an empty stomach as much as possible to avoid gastric ulcer. Coupled with the diuretic effect of caffeine, it will increase the excretion of calcium and indirectly lead to the decrease of bone mineral density. People who drink coffee regularly should pay more attention to calcium supplementation and exercise, and usually eat more milk, dried fish, cheese, green vegetables or calcium tablets. Because of diuresis, you need to drink more boiled water to avoid water loss.
Caffeine exists not only in coffee, but also in cola, black tea and other drinks, but the content is not that much. It is still suggested that people with cardiovascular diseases, arrhythmia, osteoporosis, gastrointestinal diseases, insomnia, pregnancy and so on should reduce drinking caffeinated drinks.
