These restrictions are related to daily intake of caffeine. It should not exceed 400 mg for an adult. A cup of americano contains an average of 100 mg of this substance. But we must bear in mind that the varieties, methods of roasting, grinding are different. From this the strength of the drink varies. The stronger he is, the less he is drunk.
Men are also advised to consume no more than 3-4 cups of coffee per day. Excess rates lead to a jump in blood pressure, reduces potency, disrupts sleep. It is better to stop the choice on natural ground grains, since they contain more useful substances.

The concentration of caffeine in instant coffee is greater, and it has a high acidity. It is especially harmful to people with a sore stomach, because it irritates the mucous membrane. It is not recommended to use it for those who have a sick liver, kidneys or have a heart problem.
Sublimated coffee is essentially the same instant. Only in the production process there is a process of sublimation – drying by freezing (freezing in a vacuum). This is an expensive process, so the price of the sublimated product is higher. In the sublimated granules, more of the original substances are retained, they are more useful and fragrant.

Caffeine-free in itself is beneficial, but much depends on how it is extracted. Caffeine is removed by washing with a solution of ethyl acetate or water or compressed carbon dioxide. The last two methods are considered the safest.
Coffee without caffeine contributes to the deposition of fat and increases the blood levels of harmful cholesterol.
Caffeine is not fully extracted, a small percentage of the substance remains, so the drink still gives a stimulating effect, but to a lesser extent.
The benefits of green coffee
To get green coffee, the grains are specially cleaned and dried, eliminating the roasting process. As a result, the majority of beneficial substances are retained, while the concentration of caffeine decreases.
Green coffee contains unsaturated fatty acids, vitamins, antioxidants. Since green beans still contain caffeine, you should not abuse the drink. It can increase the pressure and speed up the heartbeat.
