If you lose 1 pound a week, you need to consume 500 fewer calories a day than your daily routine. Probably no one thinks chocolate is a good diet.

Many researchers have brought good news to chocolate lovers: chocolate may be good for your health. Scientists have initially confirmed that cocoa and chocolate can improve high blood pressure, speed up blood flow and keep the heart healthy. Studies have shown that eating foods rich in flavonols can reduce the risk of cardiovascular disease. Cocoa contains a substance that helps the body process nitric oxide, which is important for blood circulation and blood pressure health, a study has found. Another study shows that flavonols in cocoa can reduce the occurrence of thrombosis by removing fats from the blood and preventing arterial blockage and platelet aggregation through antioxidation. Flavonols are antioxidants. Cocoa beans contain a lot of flavonols, as well as red wine, blueberries, peanuts, strawberries, apples and many vegetables and fruits. Scientists also found that dark chocolate contains more flavonols than milk chocolate. Cocoa powder and chocolate syrup lose a lot of flavonols in the production process.

Chocolate can replenish energy and reduce anxiety and pain. Who doesn't like this delicacy? However, some nutritionists and biochemists believe that chocolate does not have so many useful ingredients. For example, caffeine is exciting, while chocolate contains much less caffeine than a cup of coffee, usually eating chocolate bars containing 30 milligrams of caffeine and 1 cup of coffee containing 100-150 milligrams of coffee. As a result, coffee may have more benefits than chocolate has the risk of obesity, adult diabetes, heart and cerebrovascular disease, and tumors.
