Dark Chocolate

Dark chocolate is both healthy and tasty. With 64 mg in a 1-ounce (28-gram) serving or 16% of the RDI, it is extremely high in magnesium. The prebiotic fiber in dark chocolate nourishes the good bacteria in your gut and is also rich in iron, copper, and manganese.

And it's packed with healthy antioxidants, which combat the harmful molecules known as free radicals that can destroy your cells and cause disease. Given that it includes flavonols, strong antioxidant substances that stop "bad" LDL cholesterol from oxidizing and sticking to the cells lining your arteries, dark chocolate is very good for your heart. To get the best health advantages from dark chocolate, pick a product with at least 70% cocoa solids. A higher percentage is preferable.
