During the exam. Can eating chocolate really make people relax?

Candidates had better eat a piece of chocolate one hour before the exam, because eating chocolate when people are tired can refresh their minds, replenish energy and make people feel happy. Besides chocolate, sweets such as bananas and puddings can also achieve this effect. He especially reminded candidates that it is best not to drink milk for breakfast, because milk has hypnotic effect. You can drink soybean milk or mung bean porridge and a proper amount of starchy food (steamed bread, steamed buns, etc.) for breakfast. ).

Chocolate does have many health benefits.

1, which can benefit the heart and prevent cardiovascular diseases;

2, it can refresh you, and you will feel great when you eat chocolate, which is why you will be excited when you eat chocolate.

3. It is good for blood vessels. Flavonoids in chocolate can keep the elasticity of capillaries.

4, good for bones.

5. Prevent coronary heart disease.

6. Improve male immunity. The taste of chocolate can improve men's immune system. It can produce an antibody called "immunoglobulin A" to deal with minor physical problems, such as colds.

7, help to give birth. Because chocolate is small in size, high in calories and easy to absorb, eating a few pieces before labor is helpful to the production of MM.

8. It helps to prevent tooth decay. Cocoa beans are the main ingredient of chocolate, which can fight bacteria and tooth decay. The antibacterial substances in cocoa beans offset the high sugar content, so it is less harmful to teeth than other sweets.

Many people overestimate the calories in chocolate. A 40-gram bar of milk chocolate contains about 2 10 calories-enough calories to be included in a weight-control diet.

Some surveys show that many overweight people don't eat too much sugary food. It is more important to control the daily total calorie intake and energy consumption in physical activity. For example, overweight children are usually not as active as normal-weight children. In this way, even if their calorie intake reaches a reasonable level or is restricted, they may still remain overweight.

Chocolate can strengthen tooth protection.

It is generally believed that all foods containing fermentable carbohydrates will play a potential role in the formation of dental caries. Fermentable carbohydrates exist in starch and sugar, including those found in food and added to processed food.

Although chocolate contains fermentable carbohydrates, many dental experts show that chocolate may not be as easy to cause tooth decay as traditionally thought. Studies by the Foces Dental Center and the School of Dentistry of the University of Pennsylvania show that cocoa powder and chocolate may offset the sugar and acid contained in them. Cocoa powder and chocolate have also been proved to slow down the demineralization process, which is an activity that directly leads to dental caries.

In addition, a study by Hysmans Dental Center in Rochester, new york, found that milk chocolate and chocolate biscuits are one of the snacks that cause the least dental caries. "Milk chocolate is rich in protein, calcium, phosphate and other minerals," the researchers report. All these protect the enamel of teeth. In addition, because of its natural fat content, milk chocolate passes through the mouth relatively faster than other sweets. These factors are considered to be that milk chocolate is not prone to caries. "

Chocolate can lower cholesterol.

With people's increasing concern about maintaining heart health, fat (especially saturated fat) is listed as a substance that seems to be avoided. The latest research shows that not all saturated fats have the same effect.

Cocoa butter in chocolate is a natural fat in cocoa beans, which consists of saturated fatty acids, monounsaturated fatty acids and other small amounts (less than 5%). Studies have shown that cocoa butter, despite its high saturated fat content, does not raise blood cholesterol like other saturated fats. This is because the saturated fatty acids in chocolate contain a lot of stearic acid and palmitic acid. Does stearic acid have a neutralizing effect on cholesterol? It does not increase or decrease, but palmitic acid can slightly reduce cholesterol concentration, so saturated fatty acids in chocolate have no effect on blood cholesterol level. Oleic acid in monounsaturated fatty acids can reduce the cholesterol concentration in the body.

Chocolate is good for heart health.

Scientists are studying the potential effects of chocolate polyphenols on cardiovascular health. Preliminary studies have shown that those substances that may have antioxidant effects may help maintain cardiovascular health. A study found that after volunteers ate chocolate, the time required for blood oxidation was prolonged and the total antioxidant capacity of their blood was improved. Therefore, the results of this preliminary study show that eating chocolate as part of a healthy diet is helpful to maintain cardiovascular health.

Low density lipoprotein in chocolate is a complex of fat and protein, which can carry cholesterol and fat in the blood circulation. In order to maintain the health of cardiovascular system, we should not only maintain the normal level of LDL cholesterol, but also maintain the normal oxidation rate of LDL cholesterol. Monounsaturated fatty acids in chocolate contain effective components, which are also oleic acid and linolenic acid with antioxidant effect.

Chocolate won't make acne worse.

Studies in the past 20 years have shown that chocolate can neither cause nor worsen acne. Acne is the result of excessive activity of skin oil glands in adolescence. There is no need to touch the diet.

In a study conducted by the Department of Dermatology, University of Pennsylvania School of Medicine, an experimental group ate a chocolate-like food without chocolate, in which 28% of plant fat imitated the fat contained in chocolate pulp and cocoa butter. The other group ate real chocolate, but the chocolate bars tested contained chocolate paste 10 times that of ordinary 40 grams of chocolate. The result of the test is that the situation of acne in the group that eats chocolate is almost the same as that in the group that doesn't eat chocolate.

You don't have to worry that chocolate contains a lot of caffeine, because people consume very little caffeine when eating a normal amount of chocolate. For example, 28.35 grams of milk chocolate contains about 6 milligrams of caffeine, which is roughly the same as a cup of decaffeinated coffee. In addition, there are many research results that will surprise you. For example, eating chocolate candy occasionally can also reduce the possibility of alcoholism, and drinking chocolate milk may be beneficial to lactose allergy.
