Drink a cup of coffee when chatting with friends and a cup of coffee when you are tired. Coffee seems to have become a necessary "vitamin" for many people every day. People often become dependent and infatuated with coffee unwittingly. Lei Min, deputy director of the nutrition clinic at the third Hospital of Hebei Medical University, reminded everyone that although coffee is a healthy drink, office workers who drink coffee every day should not exceed 5 cups a day.

"Coffee is a drink with high nutritional value." Lei Min said that coffee is mainly made from coffee beans. Every 100 grams of coffee beans contain 2.2 grams of water, 12.6 grams of protein, 16 grams of fat, 46.7 grams of sugar, 9 grams of cellulose, 4.2 grams of ash, 120 milligrams of calcium, 170 milligrams of phosphorus, 42 milligrams of iron, 3 milligrams of sodium, 20.12 grams of vitamin B20.12 grams, 3.5 milligrams of nicotinic acid, 1.3 grams of caffeine and 8 grams of tannin.
