The main ingredient of chocolate is ground cocoa beans, which contain most nutrients needed by human body: carbohydrates, protein, vitamins (mainly vitamin B family) and minerals.

The types of chocolate can be divided by the content of cocoa powder (which can determine the color of chocolate). At present, there are mainly three kinds of chocolates on the market: pure chocolate contains 60% cocoa powder, milk chocolate contains 30%, and white chocolate does not contain cocoa powder.

The second important ingredient of chocolate is cocoa butter, which is just the opposite: there is no cocoa butter in pure chocolate; There is not much milk chocolate, only15% ~ 20%; The main ingredient of white chocolate is cocoa butter, but in fact its edible value is very small.

If you eat a whole piece of pure chocolate, you have already got half of the fat standard for one day,1/3 for iron and magnesium, and1/5 for phosphorus for one day and night.

Milk can change the characteristics of chocolate. A piece of milk chocolate contains the same fat and carbohydrate as pure chocolate, but it contains more protein and potassium (a daily share of1/7), calcium and phosphorus (a daily share of1/3) and more vitamin B2 (a daily share of1/4).

White chocolate contains few beneficial substances, which are mainly composed of fat (1/3 per day) and carbohydrate mixture (1/6 per day).

Chocolate (especially white chocolate) has a very high calorie content, which is similar to that of butter. Every 100 grams of small chocolate contains 400-600 kilocalories (this is the standard1/4 for adults). If jam or dried fruit is added to chocolate, the calorie content will increase.

Russian experts believe that pure chocolate is very healthy because it has the following benefits:

Prevent atherosclerosis in cardiovascular system and reduce the risk of infarction and stroke;

Promoting the production of serotonin (also known as "the hormone of happiness") can make the mood high, suppress depression and stimulate vitality;

Has anti-aging effect and can delay the aging of body cells;

12 years old-16 years old teenagers (it will promote excessive secretion of sebaceous glands and cause acne); A fat person;
