Dark chocolate (with 70 percent cacao or more) lowers bad cholesterol (LDL) and increases good cholesterol (HDL).Dark chocolate has recently been discovered to have a number of healthy benefits. While eating dark chocolate can lead to the health benefits described below, remember that chocolate is also high in fat.
1. It can help prevent heart disease: Like tea, dark chocolate contains flavonoids, which are compounds that act as antioxidants. Flavonoids protect cells from harmful molecules—called free radicals—that are produced when the body breaks down food or is exposed to sunlight or smoke. Free radicals can cause cell damage that leads to heart disease. Flavonoids can also lower blood pressure and reduce LDL cholesterol (i.e., the bad cholesterol) by up to 10 percent.
2. It can improve your mood: Dark chocolate stimulates the production of endorphins, chemicals in the brain that bring on feelings of pleasure. It also contains the chemical serotonin, which acts as an anti-depressant.Chocolate also contains other substances with mood elevating effects. One is phenethylamine, which triggers the release of pleasurable endorphins and potentates the action of dopamine, a neurochemical associated with sexual arousal and pleasure. Phenethylamine is released in the brain when people become infatuated or fall in love.
3. It can protect your skin: German researchers found that the flavonoids in dark chocolate absorb UV light, help protect and increase blood flow to the skin, and improve skin’s hydration and complexion.
For all of its health benefits, though, dark chocolate does contain a lot of calories. So, experts recommend sticking to no more than three ounces of the sweet stuff per day.
