And efficacy.
1, anti-aging
Because dark chocolate has a strong antioxidant effect, it prevents the human body from aging rapidly. Experiments have proved that the life expectancy of the elderly who often eat dark chocolate in moderation is significantly longer than that of the elderly who don't eat dark chocolate.
2. It can make people smart.
Eating chocolate and other foods can sharpen your mind and improve your cognitive ability in a short time.
Eating cocoa drinks rich in flavanols (the main component of dark chocolate) can promote blood flow in some important areas of the brain for 2-3 hours. The increase of blood flow in some specific areas of the brain is helpful to improve the ability of the brain and make people more acute in a short time.
3. Cold resistance
Unfortunately, this ability only works for men.
Step 4 Moisturize the panel
German researchers asked 24 women to drink half a cup of concentrated flavonoid cocoa powder every day. After three months, these female panels became more moist and smooth, and the symptoms such as pigmentation and dandruff caused by sun exposure were effectively improved. It is believed that ultraviolet rays are absorbed by flavonoids, which helps to protect and increase the blood circulation of the panel, thus improving the appearance.
How to buy dark chocolate
1, sense of smell-the making process is the soul of chocolate. Cocoa contains more than 500 aromatic substances. Only after high-temperature baking can chocolate give off a rich and unique fragrance with a little sour taste.
2, hearing-high-quality dark chocolate texture is relatively hard, when opened, it will make a crisp sound, and the cut surface is relatively smooth. Pay attention to the "own voice" of dark chocolate.
3. Taste-remember that we are tasting chocolate, not "eating" chocolate. As soon as many people get dark chocolate, they can't wait to send it to * * * and "bite" it excitedly. In fact, the melting process of dark chocolate in the mouth is the most enjoyable process. Put chocolate on your tongue and let the heat and saliva in your mouth slowly melt it. Pure dark chocolate has a high melting point, but in your mouth, it melts slower than milk chocolate and white chocolate. Therefore, if * * * melted dark chocolate is either too low in cocoa solids or contains cocoa butter substitutes. The cocoa aroma of dark chocolate is much higher than other chocolates, so the teeth and cheeks will have a strong cocoa aroma after eating.
What happens when you eat too much chocolate?
1, will be fat
Chocolate contains a lot of fat, but does not contain cellulose which can make the gastrointestinal tract peristalsis normally, so it will affect the digestion and absorption function of the gastrointestinal tract. After children eat too much, a lot of fat will accumulate in the body, which will increase the burden on the heart and gradually weaken their physique. Adults who eat too much are prone to hypertension, arteriosclerosis, gallstones and other diseases.
Because the sugar is too high, a lot of sugar will be converted into fat storage through metabolism in the body, which will also make people fat. Because the content of protein is too small, children lack protein, which will affect their growth and development, and adults will easily feel weak and tired.
2, easy to have a headache
Chocolate is rich in tyramine acid, which is the main cause of vasospasm. This substance will cause the body to produce hormones that can constrict blood vessels, and blood vessels will continue to expand to resist this contraction, and annoying headaches will appear.
So if you have a history of migraine, you'd better eat less of these foods. So the next time you have a headache, don't be tempted by chocolate. It is best to avoid it.
3, leading to menstrual disorders
If you have menstrual syndrome, which is a common disease among women of childbearing age from 1/3 to 1/2, I suggest you eat less chocolate. People have noticed that although chocolate can make people feel euphoric for a short time, eating too much chocolate during menstruation will aggravate menstrual irritability and pain.
There is no scientific basis for saying that eating chocolate during menstruation can treat dysmenorrhea. It only makes some women change their self-feeling, relieve the sensitivity of sympathetic nerve, make people feel happy and play a role in relieving dysmenorrhea symptoms. But it must not be said that dysmenorrhea can be treated.
4, will affect the development of the fetus.
Because chocolate contains caffeine, each standard-sized chocolate contains 50 milligrams of caffeine. If pregnant women consume more than 300 milligrams of caffeine every day, it may lead to miscarriage, reduce the weight of the fetus, and may also lead to premature delivery. In addition, eating too much chocolate will make some essential nutrients lack, which will affect the health of pregnant women and is not conducive to the growth and development of the fetus. Moreover, some chocolates have too high sugar content, which may induce pregnant women to suffer from gestational diabetes.
5, there will be a feeling of fullness.
Don't eat too much chocolate before meals, because it will make you feel full and affect your appetite. However, I will feel hungry again soon after a meal, which will disrupt normal life rules and eating habits and affect children's health.
