Up there you have heard with dark green or cabbage choy dark chocolate. Superfood. "Research has shown that it can improve both heart health and blood pressure, which is likely due to anti-inflammatory and antioxidant ingredients, and may even improve mood and reduce the risk of chronic disease.
Most experts appreciate the health benefits of chemical compounds called a polyphenols, especially flavanoids, plant compounds with antioxidant and anti-inflammatory properties, explains Kristin Kirkpatrick, RD, a Denver-based nutritionist and author of Skinny Liver .

But the superfood status of Dark Chocolate is likely to be a bit blown over, says Alan Aragon, MS, Men's Health nutritionist , "Dark chocolate happens to contain beneficial compounds that favorably affect various health parameters when consumed reasonably." In this case, reasonable means consume in moderation. Since chocolate is energetic (read: it has 150 to 170 calories per ounce), you can simply lay it down indiscriminately, and you can easily lose the excess calories and weigh the scales, he notes.
You want to take the snack right way? Look for dark chocolate with a cocoa content of at least 70 percent. The higher the better, says Kirkpatrick. (Less, and you're probably dealing with a mix of cream and other add-ins, she says.) Aragon prefers one or two squares of Trader Joe's Pound Plus, about 77 calories per square a day.  Then you should know what advantages you offer – starting with these three big sizes.
Dark chocolate gives you a magnesium boost.
Did you know that up to 68 percent of people do not get the right amounts of magnesium, a major player in over 300 body processes? Dark chocolate is a solid source of the mineral, says Aragon. About 3.5 ounces of dark chocolate, two squares of Trader Joe's dark chocolate, are filled with 228 mg of magnesium, so you can get well to the recommended 400 mg a day.

Dark Chocolate Helps Your Heart
Her workouts pump your heart, but thanks to anti-inflammatory and blood pressure enhancing effects of flavonols – a type of flavonoid – in the dark chocolate, the sweets could help improve heart health, says Kirkpatrick.
A study of healthy men who saw increased blood vessel function, lower blood pressure, and improved cholesterol levels twice daily for less than 0.5 g of a cocoa flavonol for two weeks. The same study also showed that these men had a lower risk of developing heart disease, having a heart attack, or dying from either.
Your brain could benefit from dark chocolate.
Flavonols are incredibly brain friendly. They could improve the function of brain cells, protect vulnerable brain cells, and even stimulate the regeneration of brain cells, for example by enhancing the action of protective proteins, as published in a review in Frontiers in Nutrition has been.
The result: According to the study, you will probably be able to take better care, think faster, and see improvements in memory.
However, the benefits could be even greater: Flavonoids in Dark Chocolate may one day be useful in treating neurodegenerative diseases such as Alzheimer's. A study in the Journal of Alzheimer's Disease found a link between the consumption of chocolate and a reduced risk of cognitive decline, possibly due to the protective effects of cocoa flavanols.
