Flavonoids in dark chocolate

The beneficial plant compounds in chocolate are called flavonoids, which contribute to the dark pigment in chocolate. Flavonoids are polyphenolic compounds found abundantly in cocoa.

Dark chocolate contains a high percentage (equal to 70 percent) of cocoa solids, and little or no added sugar. As a result, dark chocolate contains more health benefits. At the contrary, milk chocolate contains less flavonoids as evidenced by its lighter color.

Cocoa flavonoids are classified as flavanols and include the monomers, (-)-epicatechin, (+)-catechin, and procyanidins, the oligomers of these monomeric units. Flavonoids occur naturally in the cocoa plant as a way of protecting the plant. Their presence affects the taste of chocolate and they are responsible for the astringency in the unprocessed cocoa bean.

The flavonoid found in dark chocolate has been linked to decreases in blood pressure, improvements in endothelial dysfunction that promote vascular homeostasis, improvements in antiplatelet activity, improvements in insulin sensitivity, increases in high-density lipoprotein (HDL) cholesterol concentrations, improvements in cognitive, and antioxidant properties.

Furthermore, an increase in plasma antioxidant capacity and a decrease in plasma oxidation products are associated with elevated epicatechin concentrations. Research recently reported that the cocoa flavonoids decrease plasma leukotriene-prostacyclin ratios in human plasma and aortic endothelial cells (Journal of the American College of Nutrition, Vol. 23, No. 3, 197–204, 2004).

Nutrients in dark chocolate and health benefits

Many studies show that beneficial nutrients can be found in dark chocolate. Dark chocolate is made up of cocoa solids and sugar but no milk solids (prevalent in milk chocolate) and white chocolate, although referred to as chocolate had no cocoa solids, but instead is made of cocoa butter (the fat in chocolate), milk solids and sugar.

One of the nutrients in dark chocolate is called a polyphenol. Polyphenols are apart of a large family of natural compounds found in a wide variety of plant foods. They are helpful in assisting the human body protect itself from free radicals that cause oxidation.

Researchers believe that the benefits of dark chocolate are because of the flavonoids it contains, which are associated with the ability to lower the risk of heart disease and some cancers.

The heart may be vulnerable to damage by oxidation and flavonoids of dark chocolate hold potential for positive heart health effects.

Dark chocolate contains small amounts of B-complex vitamins (thiamin, or B1; riboflavin, or B2; niacin; vitamin B6’ and folate), needed for releasing energy and creating the body’s building blocks. Bone-enhancing vitamin D and antioxidant E are found in dark chocolate, which are important nutrients, too.

According to some studies done in Italy, dark chocolate has many of the same benefits as vitamin C helping the body use insulin more effectively and lower blood pressure. According to the study, participants who enjoyed 100 grams of dark chocolate daily for 15 days had reduced blood pressure and become more sensitive to insulin than they were prior to the "experiment".

Dark chocolate is plentiful in magnesium, important for brain functioning. It also boasts other nutrients, such a s copper, iron, manganese and zinc.
