Probably the most popular health food-dark chocolate
Unless you hate sweets, no one should refuse chocolate. The main ingredient of chocolate is cocoa, and what we often eat can be divided into three categories by the content of cocoa. The following figure is from left to right:
Dark chocolate with more than 55% cocoa
Milk chocolate with added milk products, cocoa content below 55%
White chocolate with no cocoa at all
The protagonist of this article is dark chocolate with the highest natural cocoa content.
Why is dark chocolate healthy?
Compared with milk chocolate and white chocolate with higher sweetness, dark chocolate is not sweet and bitter, but it has a sweet fragrance that makes people aftertaste. The% number indicated in dark chocolate represents the amount of cocoa pulp contained, and the higher the% number, the more bitter the taste. This is because antioxidants are more bitter, so the higher the% number, the more abundant the antioxidants contained, but of course, the content still depends on the type of cocoa beans and the production technology.
Cocoa contains very rich antioxidants, compared to green tea and red wine content is 2-3 times higher. The most important of these antioxidants are theobromine and catechins, both of which are unique to dark chocolate and are easily absorbed by the body. After eating dark chocolate, the blood content will increase 15-50 times.
What are the adverse effects of dark chocolate? In this study, as long as 8 grams of dark chocolate was eaten daily for one month, it improved vascular endothelial cell function. Endothelial cell function determines the elasticity of blood vessels, weakened endothelial cells are closely related to atherosclerosis symptoms, and antioxidants can also significantly improve blood pressure, blood lipids and anti-inflammatory. In addition, eating 75-100 grams per day is more effective in increasing HDL cholesterol in some studies, which also shows that dark chocolate has a very good effect on cardiovascular health.
Dark chocolate doesn't make you fat.
Dark chocolate is rich in antioxidants, but the fat and sugar content is actually a bit scary. For every 50 grams of dark chocolate, there are 20 grams of fat and 20 grams of sugar, so many people worry about obesity. But don't worry, dark chocolate will not increase the pressure on blood sugar and blood lipids.
Although the fat content of dark chocolate is high, the main fatty acids are unsaturated fatty acids like oleic acid and stearic acid, both of which have no adverse effects on blood lipids. A small study of 22 obese people with stage I hypertension tested the effect of eating 50 grams of dark chocolate containing 70% cocoa per day on a range of metabolic indicators for four weeks. The study found that eating dark chocolate had no negative effect on blood pressure, blood sugar, blood lipids and inflammation indicators. In this study, eating 20 grams of dark chocolate per day was more effective in improving insulin resistance.
In addition, studies have shown that beneficial bacteria in the intestinal tract can use the antioxidants and cellulose contained in cocoa for fermentation, thereby promoting gastrointestinal health. Participants in this study drank a beverage containing 494 mg of cocoa antioxidants every day for four weeks. The result was an increase in gastrointestinal beneficial bacteria such as bifidobacteria and lactobacilli, while reducing the number of harmful bacteria such as clostridium, so eating more dark chocolate is more reliable than eating probiotics.
Of course, dark chocolate can not be used as medicine, and we should not devalue its effect too much, but if you are addicted to chocolate, you may as well "blacken" it, which will not have a bad effect on the body, but may also improve cardiovascular health.
The last thing to mention is that white chocolate does not contain cocoa lotus, so the ingredients do not contain any antioxidants, except calories, only calories!
