Cocoa contains a variety of chemicals, including antioxidants called flavonoids. It's not clear how these might work in the body, but they appear to relax the blood vessels. This could lead to lower blood pressure, and reduce inflammation and blockage of blood vessels.
People most commonly use cocoa for heart disease and high blood pressure. It is also used for high cholesterol, memory, aging skin, and many other conditions, but there is no good scientific evidence to support these other uses.
Uses & Effectiveness ?
Possibly Effective for
- Heart disease. Eating cocoa lowers the chance of heart disease and death. Cocoa might have this effect by lowering blood pressure and improving blood vessel function.
- High blood pressure. Eating dark chocolate or cocoa products for 2-8 weeks can lower blood pressure in people with high blood pressure. But these benefits are only seen when cocoa comes from plain, unsweetened chocolate. Eating cocoa from desserts might increase the risk for high blood pressure.
Possibly Ineffective for
Cocoa can cause allergic skin reactions and might also trigger migraine headaches. It can also cause nausea, stomach discomfort, constipation, and gas.
When applied to the skin: Applying cocoa butter to the skin is likely safe for most people. It can cause a rash in some people.
Special Precautions and Warnings
Cocoa can cause allergic skin reactions and might also trigger migraine headaches. It can also cause nausea, stomach discomfort, constipation, and gas.
When applied to the skin: Applying cocoa butter to the skin is likely safe for most people. It can cause a rash in some people. Pregnancy: Cocoa is possibly safe when used in moderate amounts or in amounts commonly found in foods during pregnancy. But be sure to monitor your intake. Consuming cocoa in larger amounts is possibly unsafe because of the caffeine it contains. Caffeine found in cocoa crosses the placenta. High doses of caffeine during pregnancy might increase the risk for premature delivery, low birth weight, and miscarriage. Keep caffeine consumption below 300 mg per day during pregnancy. Chocolate products provide 2-35 mg caffeine per serving, and a cup of hot chocolate provides approximately 10 mg. So these products probably aren't a big concern. But unsweetened, dry cocoa powder can contain up to about 200 mg of caffeine per cup
Breast-feeding: Cocoa is possibly safe when used in moderate amounts or in amounts commonly found in foods while breast-feeding. But caffeine is also a concern during breast-feeding. Breast milk concentrations of caffeine are thought to be about half the level of caffeine in the breast-feeding parent. If too much chocolate (16 oz per day) is consumed when breast-feeding, the nursing infant may become irritable and have frequent bowel movements because of the caffeine.
Anxiety: The caffeine in cocoa might make anxiety disorders worse when consumed in large amounts.
Bleeding disorders: Cocoa can slow blood clotting. Consuming a lot of cocoa might increase the risk of bleeding and bruising in people with bleeding disorders.
Heart conditions: Cocoa contains caffeine. The caffeine in cocoa might cause irregular heartbeat in some people and should be used cautiously in people with heart conditions.

Diarrhea. Cocoa contains caffeine. The caffeine in cocoa, especially when taken in large amounts, can make diarrhea worse.
Gastroesophageal Reflux Disease (GERD): Cocoa might make the symptoms of GERD worse.
Glaucoma: Cocoa contains caffeine. The caffeine in cocoa increases pressure in the eye and should be used cautiously in people with glaucoma.
High blood pressure: Cocoa contains caffeine. The caffeine in cocoa might increase blood pressure in people with high blood pressure. But for people who consume caffeine regularly, it might not be a big increase.

Cocoa is regularly eaten in chocolate products. Bitter chocolate is produced by pressing roasted cocoa beans between hot rollers. Cocoa powder is produced by squeezing the fat (cocoa butter) from bitter chocolate and powdering the remaining material. Sweet chocolate is produced by adding sugar and vanilla to bitter chocolate. The percentage on a chocolate bar tells you how much sugar has been added. For example, a 70% cocoa bar contains 70% cocoa and 30% sugar.
