Coffee is a tonic and beverage that has a positive effect on the cardiovascular system. However, when drinking coffee, it is necessary to monitor the amount of caffeine consumed, since exceeding the permissible level can negatively affect human health.
The consequences of drinking too much coffee
Coffee is useful, however, when consumed in large quantities, the drink can cause the development or complication of certain diseases. For example, excessive consumption of this drink leads to caffeine poisoning, which manifests itself in nervousness, tachycardia, anxiety attacks and insomnia.
Coffee is contraindicated for people who have serious diseases of the cardiovascular system - caffeine has a stimulating effect on the heart, increasing blood circulation and, accordingly, the load on the heart. It is also dangerous to drink the drink for those who have a highly excitable nervous system.
Coffee is also too harsh for patients with ulcers, gastritis and stomach acidity. It is dangerous to drink coffee for patients with pancreatitis and diabetes, since the drink can negatively affect the digestive tract.
Coffee consumption rate
The allowed amount of coffee depends on the amount of caffeine that will be contained in one cup. A safe dose is calculated on the condition that you cannot drink more than 200 mg of caffeine at a time. This amount is equivalent to 2 teaspoons of instant coffee or 3 tablespoons of natural coffee. If this dosage is observed, the drink will have the desired effect and at the same time will not cause harm to health.
The permissible dose per day should not exceed 400-600 mg.
However, the amount of caffeine in one cup may depend on both the degree of roast of the coffee beans and the preparation of the beverage. For example, one European cup of espresso contains about 100 mg of caffeine, while a double espresso doubles the amount. A cup of cappuccino contains no more than 80 mg of caffeine, and the concentration of the substance in instant coffee can vary from 65 to 100 mg.
The absorption of caffeine also depends on the presence of additives in the drink and the total volume of liquid. For example, the digestibility of espresso will be much higher than that of an Americano, since the volume of a cup of espresso will be much lower. Cappuccino and Americano with milk will be absorbed even more slowly, which will affect the effect of caffeine on the body.
You can reduce the amount of caffeine you consume by changing the type of coffee you use. For example, the concentration of the substance in Arabica is much lower than in Robusta coffee.
The most useful drink is natural coffee, which is made from freshly ground beans. Instant coffee loses in the degree of nutrient content due to the processing that it undergoes during the manufacturing process. Instant coffee does not contain some of the lipids, vitamins, minerals and carbohydrates found in coffee beans.
