It's caffeine, not the misunderstanding of coffee addiction.

Food misunderstanding

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

Why does drinking 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 properly drinking some caffeinated drinks can refresh your mind and lift your spirits. The refreshing effect is very different from some irritating substances, such as alcohol, because caffeine acts on the body for a short time. That's why we always see a lot of people drinking coffee, tea or coke in the workplace.

When it comes to caffeine, people's understanding of it is even more inadequate, there are two main misunderstandings, one is that only know that caffeine has a refreshing effect, drinking more will affect people's sleep. In fact, caffeine is a natural substance found in the seeds, leaves or fruits of many plants, known as coffee beans, cocoa beans and tea.

The second misunderstanding is that many people often think that caffeine causes osteoporosis. In fact, insufficient calcium intake 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 although caffeine increases calcium excretion, insufficient calcium intake is the main reason.

So how on earth can we meet people's spiritual needs without affecting their health? This is the knowledge of caffeine intake. In our daily drinks, caffeinated drinks are mainly coffee, tea, cola and so on. It is generally believed that the safe daily intake of caffeine for adults is 300 milligrams in 240 milliliters per cup, 65 to 120 milligrams per cup of coffee, 20 to 90 milligrams per cup of tea and 23 to 31 milligrams per cup of Coke. 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 will not cause health problems caused by caffeine.

Of course, any good thing that is excessive will lose its original effect. Therefore, experts suggest that it is best to decide whether to drink more or less based on the effects of caffeine on your sleep, blood pressure and digestive system, while lactating women and pregnant women should consume less caffeine.
