Second, the disadvantages of dark chocolate:

It should be noted that dark chocolate and calcium-containing foods cannot be eaten together for a long time in large quantities. According to Hualong. com, common calcium-containing foods include eggs, milk, soybean milk, goat's milk, sesame, tofu, seafood, etc. Because dark chocolate contains oxalic acid, eating a small amount of dark chocolate with calcium-containing foods will not affect the absorption of calcium in food.

It won't form stones, but eating dark chocolate and calcium-containing food together for a long time and in large quantities will form calcium oxalate which is insoluble in water and can't be absorbed by the human body, which has a certain inhibitory effect on the digestion and absorption of nutrients, and will also cause people to have symptoms such as diarrhea and dry hair, which will affect the growth and development of the human body. Even the deposition of calcium oxalate may induce stone symptoms of various organs, such as kidney calculi and gallstones.

In addition, the oxalic acid in chocolate combines with calcium ions to form calcium oxalate, which will be excreted in urine, which will reduce the intake of calcium in human body and lead to calcium deficiency in human body in the long run.

Precautions:

When choosing dark chocolate, we can't just pursue the content of cocoa. Generally speaking, dark chocolate with cocoa content over 80% has a bitter taste, which is difficult for most people to accept. Consumers need to choose suitable dark chocolate according to the acceptance of cocoa taste.

Try not to eat dark chocolate in the early morning or before meals, because eating a little dark chocolate will make people feel full, and they will not feel hungry when eating, but they will feel hungry soon after meals. Eating dark chocolate before meals will also lead to poor absorption and nutrition of food, disrupting normal life rules and eating habits, thus affecting their health.
