Caffeine is a popular natural stimulant. It helps to wake up, activates mental processes, gives vigor. However, in excessive quantities, the use of a stimulant can be dangerous to the body. Knowing which drinks are high in caffeine will help regulate your intake.
Instructions
Step 1
Caffeine is found in large quantities in coffee. It was from these grains that the stimulant was derived at the beginning of the 19th century by the scientist Friedrich Runge. However, the amount of caffeine depends on both the method of preparation of the drink and the selected variety.
Step 2
The most popular in the world are two types of coffee: Arabica and Robusta. The latter is distinguished by a very high content of caffeine - up to 200 mg per 170 g. In arabica it is two to three times less. It is a misconception that the richer the taste of coffee, the higher the level of caffeine in it. However, drinks made with a cezve or a coffee maker have the brightest flavors. There is not very much caffeine in them, because the element is released gradually, and its amount directly depends on the duration of contact of the product with boiling water. Therefore, the most stimulant is contained in drinks infused with ground coffee.
Step 3
Caffeine is also found in tea. After drinking this drink, the stimulating effect will be less pronounced, but longer in time. Tea has such an effect due to the tannins included in the composition. You can determine the saturation of tea with caffeine by the shade of the drink: the more intense it is, the more element is released. On average, one cup of a black product contains 40 mg of a stimulant, a green one - 30 mg.
Step 4
Hot chocolate and cocoa also contain caffeine (about 40-50 mg). However, its effect is practically neutralized by the addition of milk and sugar. In such a "community", caffeine affects the nervous system in a very mild and beneficial way. Therefore, these drinks are allowed to be used in baby food.
Step 5
Of the drinks, caffeine is also found in lemonades. Most of the stimulant is found in Pepsi and Coca-Cola (up to 10 mg per 100 ml). However, it should be noted that this caffeine is not natural, synthetic. They are almost identical in action. Due to the high caffeine content in soda, the product is not recommended for children in large quantities.
Step 6
On the basis of the action of caffeine, the popular energy drinks are created today. In one small jar (150 ml), the content of the stimulant can reach up to 80 mg. Frequent use of such products adversely affects the functioning of the nervous and cardiovascular systems. It is also necessary to remember: the constant use of caffeinated beverages can be addictive.
Step 7
Caffeine can affect the body in two ways: tonic and toxic. The response is dose dependent. An adult can safely consume about 300 mg of caffeine per day.
