1, moderate eating of dark chocolate (chocolate without milk) can increase the antioxidant flavonoids in the blood and prevent heart disease.

2. Although chocolate contains a lot of saturated fat, the saturated fat in chocolate will not raise your cholesterol level. In the past few years, researchers have found that chocolate contains steroids, which are healthy ingredients in green tea and red wine. Now many studies show that dark chocolate is especially good for people's health.

Second, the disadvantages:

1, eating too much chocolate will cause digestive problems. Just like all foods with high fat content (above 30%), eating too much chocolate can also cause stomach pain (such as stomach pain, bloating, diarrhea or constipation, etc.).

2. Just like coffee and strong tea, chocolate also has an exciting effect, which will make it more difficult for people with poor sleep to fall asleep.

3. Chocolate, cheese and red wine contain tyramine, which is an active acid and one of the main causes of headaches. This substance can cause the body to produce hormones that can constrict blood vessels, and blood vessels are constantly expanding to resist this contraction, which creates annoying headaches.

The benefits of eating dark chocolate:

1, eat dark chocolate to control blood pressure. Dark chocolate helps blood pressure because of its high flavanol content, which promotes the production of nitric oxide that relaxes blood vessels. Studies have shown that high blood pressure and liver injury in liver vessels are closely related to chronic liver disease. Dark chocolate can improve blood flow in the liver, which has been confirmed in previous studies. Scientists are now studying whether dark chocolate can also prevent liver damage.

2. Eating dark chocolate is good for the heart. There are many ways to protect the heart, among which eating more pure dark chocolate is a good way. This is because pure dark chocolate is rich in flavonoids, which can prevent blood fat from depositing on the inner wall of blood vessels and prevent vascular embolism.

3. Eat dark chocolate to lose weight. Dark chocolate, where cocoa accounts for more than 70%, is rich in antioxidants, which can help metabolism and burn fat, thus achieving the effect of losing weight.

4, eat dark chocolate to fight cancer. New research has found that chocolate can starve cancer cells. Many studies have confirmed that chocolate has many antioxidants, and the antioxidant activity of dark chocolate is three times that of red wine. Its polyphenol content is four times that of green tea. How to choose? Choose dark chocolate with purity above 65%, and the darker the better.

5. Eat dark chocolate to whiten teeth. Theobromine in dark chocolate helps to make enamel stronger, thus preventing tartar and tooth discoloration.

6. Eat dark chocolate to relieve arterial disease. Dark chocolate helps to improve blood circulation in the legs and relieve arterial diseases. Further research shows that the concentration of nitric oxide in patients who eat dark chocolate is increased, which is a powerful vascular relaxing factor, which can promote the expansion of peripheral arteries and increase blood flow in legs.

This study shows that dark chocolate rich in polyphenols may be an effective relief for pain, spasm or fatigue caused by vascular problems.
