1. REDUCES YOUR RISK OF HEART DISEASE
Research shows that dark chocolate promotes heart health. In 2007, researchers proved that this type of chocolate increased the diameter of coronary arteries, thus improving blood flow.
A 2009 study found it boosted insulin resistance and blood lipids, indicating that it may also help prevent type 2 diabetes.
2. PROVIDES ANTIOXIDANTS
Real dark chocolate provides some of the same antioxidants found in red wine, tea, and apples. These nutrients protect our cells from damage from free radicals, which cause premature aging and increase your risk of heart disease and cancer.
3. MAY LOWER CHOLESTEROL LEVELS
High levels of LDL cholesterol can be harmful, since it gathers in the arteries, hardens, and gradually narrows the arteries and increases the risk of blood clots.
Eating dark chocolate may help to reduce your chances of accumulating LDL. A 2012 study found that participants who ate 50 grams of dark chocolate for 15 days had lower LDL levels and higher levels of HDL "good" cholesterol.
4. CONTROLS BLOOD SUGAR LEVELS
Most processed snacks spike your blood sugar levels, but not dark chocolate. It has a glycemic index of 23, putting it in the "low glycemic index" category. In contrast, a regular Snickers bar has a rating of 68, while honey is at 87.
5. CURBS HUNGER
The advantage of dark chocolate as a snack is it satisfies without being too filling, due to its natural ability to suppress appetite.
A 2011 study reported that dark chocolate promotes satiety, lowers the desire to eat something sweet, and suppresses the urge to eat more.
