Drinking too much coffee can lead to the accumulation of melanin in the body and darken the complexion.

A cup of coffee for breakfast has become a "habit" for many people. But British dietary nutritionist Amanda Ursula reportedly suggests that drinking coffee in the morning can affect the day's work. Because drinking coffee at breakfast will make your heart beat faster and cause your stomach to contract. In addition, the sugar consumed in breakfast will be quickly absorbed by the body, causing a strong sense of hunger. At this time, people will become irritable, absent-minded and don't want to do anything but eat.

Ursula also believes that it is best to eat a less greasy lean meat or fish dish for lunch and drink a small cup of coffee. At this time, coffee helps to refresh, eliminate drowsiness and keep a clear head. You can also eat eggs, which helps to improve memory. Macaroni or pancakes can slow down the state of work, because when carbohydrates enter the body at noon, it slows the brain and reduces attention.

Margarita Koroleva, a Russian nutritionist, pointed out that if you care about your appearance, you should eat less than 70 grams of coffee before 12:00 and no more than three cups a day. Because drinking too much coffee will lead to the accumulation of melanin in the body, making the skin dim.
