Coffee has always been controversial, and many people will write about the benefits of coffee to human health. For example, drinking coffee can play a refreshing role, coffee can promote the decomposition of fat and help control weight and so on. However, some people feel uncomfortable after drinking coffee, and coffee is not suitable for everyone. When drinking coffee, we should also pay attention to its negative effects.
Coffee affects sleep.
Coffee contains caffeine, and many people are a little worried about caffeine. Caffeine can mention the refreshing effect, and it is precisely because of this effect that caffeine may also affect our sleep. The metabolism of caffeine takes about 8~ 12 hours. If you drink coffee at dinner, half of caffeine is metabolized in your body until you sleep, and the remaining half of coffee will affect your sleep. I want to sleep, but I can't sleep. That taste is not good at all.
Drinking coffee is addictive.
Drinking coffee regularly will lead to the body's tolerance to coffee. After drinking coffee for a period of time, drinking the same dose of coffee will not refresh your mind. So we can only increase the consumption of coffee to produce the previous effect. If you want to quit coffee at this time, you may have some uncomfortable symptoms, such as headache, dizziness, fatigue, nausea, etc., and it takes an adaptation period to get better.
Drinking coffee can lead to osteoporosis
Osteoporosis was once thought to be a problem only for the elderly, but now the onset age of osteoporosis tends to be younger. Drinking too much coffee will also increase the risk of osteoporosis, because coffee will hinder the absorption of calcium. When the absorption rate of calcium decreases, the risk of osteoporosis will also increase. At this time, you need to eat more foods with high calcium content, and at the same time, you should separate the time of eating these foods from the time of drinking coffee to ensure that the absorption of calcium is not affected.
Drinking coffee can cause heartburn.
Some people will have stomach discomfort after drinking coffee, such as heartburn or acid reflux, which will also make people miserable. Caffeine can stimulate the stomach, increase the secretion of gastric acid, and damage the gastric mucosa, so stomach diseases appear. For those who have stomach trouble from drinking coffee, try not to touch coffee. Even if it is low-alcohol coffee, I suggest you drink less or not at all.
Drinking coffee can indeed have some positive effects on the human body, and these positive effects are also based on the dosage of drinking coffee. For ordinary people, drink no more than two cups of coffee every day. If you drink too much coffee, these disadvantages will appear. And pay attention to the choice of coffee, try to choose freshly ground coffee, and don't drink instant coffee. The content of sugar in instant coffee is high, which easily increases the risk of obesity.
