Do you like to drink a cup of coffee or black tea in the morning, after lunch have a bar of chocolate and in the evening get some caffeinated drinks? You are not alone. Almost 90 percent of adults reach for some products with caffeine if they feel a lack of energy. But doesn’t it harm their health?
The impact of caffeine on human health is determined by many factors: genetics, age, sex, body weight, medications used and so on. Caffeine reduces headache. Only one cup of coffee and the headache is gone. Besides, it positively affects liver. Caffeine reduces progression of liver fibrosis so people who have some liver diseases, can enjoy a cup of coffee every day.
One of the most common myths about this stimulant is that you can get addicted to caffeine. However, this is not true. The studies of World Health Organization show that even those people who are using huge amounts of caffeine for a long time, are able to refuse it if needed. Additionally, scientific studies have shown that up to three cups of coffee per day does not pose risk of developing heart disease. Unlike artificial nutrients, caffeine does not accumulate in the body. It also has no effect to our digestive system.
However, if daily intake of caffeine is more than 500 mg (more than 4-5 cups of coffee), it may cause negative effect on health. It can increase nervousness, irritability and can also contribute to insomnia. Pregnant women are also recommended to refuse drinking coffee and other caffeinated products.
