Scientific Facts

​

Heart Health Dark chocolate might help prevent cardiovascular health problems that result from elevated blood pressure and cholesterol, according to a study of more than 2,000 patients with metabolic syndrome -- a combination of conditions that increase the risks for heart disease and diabetes. Participants in the study, published in the May 2012 journal "BMJ," consumed 100 grams of dark chocolate daily. Researchers projected that daily dark chocolate consumption is a healthy habit that could reduce the incidence of metabolic syndrome-related heart attacks and strokes by nearly 1 percent.

​

Cancer Prevention Antioxidants in cocoa may give dark chocolate potential cancer-preventive benefits, according to a study published in 2009 in "Nutrition and Cancer." The review of previously published research found that strong antioxidant activity in cocoa and cocoa products, such as dark chocolate, prevent inflammation and oxidation -- cell damage due to accumulated toxins and waste products; both conditions are associated with increased cancer risk.

​

Antidepressant Benefits Dark chocolate improved mood in healthy, middle-aged participants in a study reported in "Journal of Psychopharmacology." Participants who drank a dark chocolate beverage containing 500 milligrams of cocoa polyphenol compounds each day for 30 days reported improved feelings of calmness and contentedness. However, the effects did not occur after a single dose, implying that cocoa may not provide immediate benefits. Additionally, testing in this study did not reveal cognitive benefits of chocolate. Researchers noted that this study, published in January 2013, may be the first of its kind to show mood-boosting benefits of chocolate in healthy individuals and indicates a potential role for chocolate as a natural treatment for clinical anxiety or depression.

​

Blood Vessel Benefits "Hypertension" found that dark chocolate protected blood vessels from damaging effects of elevated blood sugar levels, such as occur after high-carbohydrate meals. Healthy participants consumed 100 grams of dark chocolate a day for three days; after that, tests of their blood circulation following a dose of glucose revealed improved blood flow and lower blood pressure compared to a control group that consumed antioxidant-free white chocolate.

​

Detoxification Dark chocolate might help protect your nervous system from the damaging effects of air pollution, dark chocolate prevented inflammation that occurred in a part of the brain stem in mice exposed to particulate matter and toxins in Mexico City air for 16 months. Dark chocolate also restored impaired antioxidant defense systems in mice that had breathed the polluted air.

​

The bioactive compounds in dark chocolate may also be great for your skin.

The flavonols can protect against sun damage, improve blood flow to the skin and increase skin density and hydration.

The minimal erythemal dose (MED) is the minimum amount of UVB rays required to cause redness in the skin 24 hours after exposure.

In one study of 30 people, the MED more than doubled after consuming dark chocolate high in flavanols for 12 weeks.

If you're planning a beach vacation, consider loading up on dark chocolate in the prior weeks and months.

 

Dark chocolate may also improve the function of your brain.

One study of healthy volunteers showed that eating high-flavanol cocoa for five days improved blood flow to the brain

Cocoa may also significantly improve cognitive function in elderly people with mental impairment. It may improve verbal fluency and several risk factors for disease, as well  

Additionally, cocoa contains stimulant substances like caffeine and theobromine, which may be a key reason why it can improve brain function in the short term

​

Dark chocolate is very nutritious with its rich properties of cocoa. A decent quantity of soluble fiber and minerals exist here. In the market we can found quality dark chocolate which is boosted with fiber, iron, manganese, etc.

​

caffeine causes dehydration which affects our digestion system. It also can increase the risk of kidney stone, since dark chocolate contains oxalates. So if you are not interested to have kidney stone issues, kindly have a look at you dark chocolate consumption.
