Coffee is a favorite drink of many people. We start the day with a cup of coffee and drink it throughout the day. But is it so safe? How many cups of coffee can you drink per day without harming your health?
There are about 2,000 different ingredients in coffee. Coffee contains proteins, carbohydrates, fats, organic acids, and mineral salts of iron, calcium, potassium, phosphorus, as well as vitamins B1, B2 and PP. The energy value of one cup of coffee without sugar is less than 9 kcal.
It tones up this drink due to its caffeine content. Small amounts of coffee are healthy. In the long term, this drink can significantly lower the risk of Parkinson's disease, gallstones, kidney stones, and even cirrhosis of the liver. Coffee is a source of antioxidants. The chlorogenic acid it contains can help with weight loss.
But there are risks: heart disease and osteoporosis. Drinking large amounts of coffee can have a negative impact on health, especially on the digestive as well as the nervous system.
Let's take a closer look at the side effects of coffee abuse:
1. Drinking coffee on an empty stomach, for example, is not recommended in the morning. this stimulates the release of hydrochloric acid. This can have consequences ranging from abdominal pain, flatulence to colon cancer.
2. Risk of gastrointestinal ulcers and acidity. The caffeine and acids in this drink irritate the walls of the stomach and the surface of the small intestine. For people diagnosed with ulcers, gastritis and irritable bowel syndrome, doctors recommend avoiding coffee altogether.
3. Coffee can cause heartburn as it relaxes the esophageal sphincter. This small muscle should be tightly closed after you eat something to prevent your stomach contents and hydrochloric acid from entering your esophagus.
4. Coffee enhances intestinal motility. But you do not need to use coffee specifically for this quality. The contents of the stomach pass into the small intestine faster than required before being completely digested. This increases the chances of irritation and inflammation of the gastrointestinal tract and interferes with the absorption of nutrients from food.
5. Deficiency of minerals. People who drink large amounts of coffee may have difficulty absorbing enough minerals from food. Coffee affects the absorption of iron in the stomach. It also has a diuretic effect, so the body loses important minerals and trace elements: calcium, zinc, magnesium.
6. Drinking large amounts of coffee affects the production of stress hormones, cortisol, adrenaline and norepinephrine. These hormones increase your body's heart rate and blood pressure. All these indicators correspond to nervous tension and stress. It turns out that we artificially induce such a state in ourselves. Caffeine is known to interfere with the metabolism of GABA (gamma-aminobutyric acid), which is a neurotransmitter involved in regulating mood and stress levels.
Coffee has both advantages and disadvantages. Make sure you are drinking real coffee and not a substitute. In order not to harm your health, stick to the norm - 2 cups of coffee a day.
