The six harmful effects of coffee? It’s actually a misunderstanding!

The claim that coffee has six harmful effects is actually a misunderstanding. As a common beverage, drinking coffee in moderation does not cause the six harmful effects. Although excessive drinking may cause some discomfort, such as insomnia and palpitations, drinking coffee in moderation is beneficial to health, such as refreshing the mind and improving concentration. We should look at the pros and cons of coffee correctly and drink coffee scientifically and rationally.

In today's fast-paced society, coffee has become a must-have drink in many people's daily lives. The dangers of coffee are always hyped up by some self-media, which makes people worried. Let's talk about the so-called "six major dangers of coffee" and see if these claims are tenable.

1. Coffee can cause insomnia

Many people believe that coffee can cause insomnia because it contains caffeine, but in fact, the impact of caffeine on each person varies. For people who are sensitive to caffeine, it may indeed cause insomnia or aggravate insomnia symptoms, but drinking in moderation, such as one to two cups a day, will not cause insomnia for most people. The caffeine content in coffee is not the highest. Caffeine is also found in tea, chocolate and some energy drinks.

2. Coffee can cause osteoporosis

Some people believe that coffee can affect calcium absorption and thus lead to osteoporosis, but this statement has not been supported by conclusive evidence. The oxalic acid in coffee may interfere with calcium absorption, but this effect may only occur if consumed in large quantities. Drinking coffee in moderation has more benefits than disadvantages because coffee itself contains certain minerals and antioxidants.

3. Coffee can exacerbate cardiovascular disease

This statement mainly stems from the fact that caffeine and other bioactive ingredients in coffee may stimulate the cardiovascular system. However, studies have shown that for healthy people, drinking coffee in moderation does not increase the incidence of cardiovascular disease. Some ingredients in coffee, such as polyphenols, may even have certain antioxidant and anti-inflammatory effects, which are beneficial to cardiovascular health.

4. Coffee can cause stomach pain

Some people may feel stomach pain after drinking coffee, which is usually because caffeine stimulates the secretion of gastric acid. However, for people with healthy stomachs, drinking in moderation will not cause much impact. Some studies have shown that some substances in coffee may have a certain auxiliary effect on the treatment of gastritis and gastric ulcers.

5. Coffee affects sleep quality

Although coffee contains caffeine, as mentioned earlier, its effect on sleep quality varies from person to person. Many other ingredients in coffee, such as chlorogenic acid, may have a positive effect on human metabolism and health. Drinking coffee in moderation does not significantly affect sleep quality.

6. Coffee disrupts women’s menstrual cycle

Some people believe that coffee can affect women's hormonal balance and disrupt their menstrual cycle, but scientific research has not clearly confirmed this. Many women have found that drinking coffee in moderation does not have a significant effect on their menstrual cycle.

Drinking coffee in moderation will not cause the above six hazards. We should look at the pros and cons of coffee rationally, drink coffee reasonably according to our own physical condition and needs, and do not need to worry too much about the harm of coffee, but it is not advisable to drink excessively. While enjoying the deliciousness and refreshing effects of coffee, we should also pay attention to maintaining a healthy lifestyle.
