1, heartbroken person.

Studies have found that some foods can relax the lower esophageal sphincter between the esophagus and the stomach and lose the function of preventing food from flowing back, and chocolate is one of them. Another study pointed out that chocolate contains at least four substances that can easily cause relaxation of the lower esophageal sphincter, including caffeine, theobromine, theophylline and fat. Therefore, people who have heartburn for a long time should try to stay away from chocolate.

2, people who are prone to headaches.

Heavy work pressure makes people have a splitting headache, but don't ignore that eating food is also one of the factors that induce headaches. Although chocolate tastes charming, tyramine contained in it is the chief culprit of headache. Therefore, the following headaches, such as chocolate, alcoholic drinks, dry cheese, smoked pork and bread and cake yeast, are best avoided.

3. People with cardiovascular diseases, diabetes and obesity.

Foods with high calorie, high fat and high sugar linked to these nouns are tantamount to telling people to be vigilant and eat less. Even people with normal weight and no chronic diseases should not eat too much chocolate and reduce the intake of oil and sugar in other diets. In addition, eating more vegetables can reduce fat absorption and accelerate fat excretion.

Dark chocolate can't be eaten with anything.

1. Dark chocolate should not be eaten with foods containing calcium.

Because dark chocolate contains oxalic acid, dark chocolate should not be eaten with calcium-containing foods, otherwise it will combine to form calcium oxalate which is insoluble in water and cannot be absorbed by the human body.

After eating, it will inhibit the digestion and absorption of nutrients to a certain extent, and there will be symptoms such as diarrhea and dry hair, which will affect growth and development. Because of the deposition of calcium oxalate, it can even induce calculus diseases in various organs, such as kidney calculi's disease and gallstones.

In addition, oxalic acid in chocolate combines with calcium ions, and calcium oxalate discharged from urine will also reduce calcium intake, which will lead to calcium deficiency in the human body in the long run.

Common calcium-containing foods: eggs, milk, soybean milk, goat's milk, sesame seeds, tofu and seafood.

2. Dark chocolate should not be eaten with high-sugar food.

Because dark chocolate itself contains sugar, if it is eaten with high-sugar food at this time, it is easy to make the blood sugar in the body rise rapidly. Especially for diabetic patients, it is more necessary to put an end to this situation.

Common high-sugar foods: bread, cream cake, ice cream, honey, sugar, etc.
