It's caffeine, not addiction.

Food Mistakes

Finally survived the long summer, but the spirit will still feel tired, the original "autumn lack" followed. At this time, many friends like to have a cold cup of cola or tea, and soon feel a lot more comfortable.

Why do these drinks make people feel refreshed? It turns out that these drinks often contain a small amount of caffeine, which helps people reduce fatigue caused by increased energy consumption in hot weather. And drink some caffeinated drinks properly, you can refresh your mind and cheer up. This refreshing effect is very different from that of stimulants, such as alcohol, because caffeine has a relatively short duration of action on the body. That's why we see so many people drinking coffee, tea or coke in the workplace.

When it comes to caffeine, people's understanding of it is even less sufficient, there are two main aspects of misunderstanding, one is only know that caffeine has refreshing effect, drink too much will affect people's sleep. Caffeine is a naturally occurring substance found in the seeds, leaves or fruits of many plants, known as coffee beans, cocoa beans and tea leaves.

The second myth is that many people often think caffeine causes osteoporosis. In fact, calcium deficiency is the main cause of osteoporosis. Other factors include hormones, exercise, nutrients, mineral and calcium intake, and people's eating habits, which are not absolutely related to caffeine intake, there is no direct evidence that caffeine causes osteoporosis, and some studies have found that caffeine increases calcium excretion, but insufficient calcium intake is the main cause.

So how can we satisfy people's spiritual needs without affecting their health? That's how much caffeine you consume. In our daily drinks, caffeinated drinks mainly include coffee, tea, cola and so on. It is generally believed that the safe daily intake of caffeine for adults is 300 mg, which is measured in 240 ml. The amount of caffeine contained in each cup of coffee is 65 to 120 mg, the caffeine content of each cup of tea is 20 to 90 mg, and the caffeine content of each cup of cola is 23 to 31 mg. So for the average person in good health, drinking 2 to 3 cups of coffee or 5 to 6 cans of caffeinated cola a day does not cause health problems caused by coffee.

Of course, anything good in excess loses its effect. Therefore, experts suggest that it is best to decide whether to drink more or less according to the effects of caffeine on their sleep, blood pressure and digestive system, while lactating women and pregnant women should consume less caffeine.
