The Health Benefits of Dark Chocolate: Separating Fact from Fiction
Chocolate is often considered a guilty pleasure, something that should be consumed in moderation due to its high sugar and fat content. However, studies have shown that dark chocolate, which is high in cocoa solids, may have some health benefits. In this article, we will explore the potential health benefits of dark chocolate and what science has to say about it.
Nutritional Value of Dark Chocolate
Dark chocolate is made from cocoa beans, which are rich in flavonoids - a type of antioxidant. The higher the percentage of cocoa solids in the chocolate, the more flavonoids it contains. Dark chocolate also contains a range of minerals, including iron, magnesium, and copper. In small amounts, dark chocolate can be a good source of these essential nutrients.
Heart Health
Studies have shown that consuming dark chocolate may have a positive impact on heart health. The flavonoids in dark chocolate can improve blood flow, reduce inflammation, and decrease blood pressure. A study published in the American Journal of Clinical Nutrition found that consuming dark chocolate for two weeks improved blood vessel function in healthy adults.
Brain Function
The flavonoids in dark chocolate may also have a positive impact on brain function. Studies have shown that consuming cocoa flavanols can improve cognitive function in elderly individuals. Another study found that consuming cocoa flavanols improved mental performance and increased blood flow to the brain in young, healthy adults.
Skin Health
The antioxidants in dark chocolate may also have benefits for skin health. The flavonoids in dark chocolate can improve skin hydration and thickness, as well as protect against sun damage. A study published in the Journal of Cosmetic Dermatology found that consuming cocoa flavanols improved skin elasticity and decreased skin roughness in women.
Mood Enhancement
Many people turn to chocolate as a comfort food, and there may be some science behind this. Dark chocolate contains anandamide, a neurotransmitter that can help enhance mood and promote feelings of pleasure. Additionally, dark chocolate can increase serotonin levels in the brain, which can help improve mood and reduce symptoms of depression.
Conclusion
While the health benefits of dark chocolate are not yet fully understood, the research is promising. Eating small amounts of dark chocolate may have benefits for heart health, brain function, skin health, and mood enhancement. However, it is important to note that not all chocolate is created equal - milk chocolate and most types of chocolate candy do not contain enough cocoa solids to have any health benefits. When looking for dark chocolate, choose a variety that is at least 70% cocoa solids to get the most benefits.
