Cacao, the main ingredient in chocolate, has been consumed for thousands of years for its potential health benefits. Cacao contains flavonoids, which are a type of plant nutrient known for their antioxidant properties. The aim of this paper is to summarize the potential health benefits of cacao based on research available on PubMed.
Cardiovascular Health:
Cacao has been shown to have potential benefits for cardiovascular health. A study published in the American Journal of Clinical Nutrition found that consuming high-flavanol cocoa for four weeks improved endothelial function, which is an important marker of cardiovascular health. Another study published in the Journal of the American College of Cardiology found that consuming dark chocolate reduced blood pressure in individuals with hypertension.
Mood Enhancement:
Cacao may also have mood-enhancing properties. A study published in the Journal of Psychopharmacology found that consuming dark chocolate improved mood and decreased symptoms of anxiety in healthy adults. Another study published in the Journal of Affective Disorders found that consuming dark chocolate improved symptoms of depression in individuals with major depressive disorder.
Cognitive Function:
Cacao may also have potential benefits for cognitive function. A study published in the Journal of Nutrition found that consuming cocoa flavanols improved cognitive performance in healthy adults. Another study published in the American Journal of Clinical Nutrition found that consuming high-flavanol cocoa for three months improved cognitive function in individuals with mild cognitive impairment.
Skin Health:
Cacao may also have benefits for skin health. A study published in the Journal of Nutrition found that consuming high-flavanol cocoa for 12 weeks improved skin texture, hydration, and blood flow in healthy women. Another study published in the Journal of Investigative Dermatology found that consuming cocoa flavanols improved skin elasticity and reduced wrinkles in middle-aged women.
Conclusion:
The potential health benefits of cacao are numerous and varied, ranging from cardiovascular health to skin health. While more research is needed to fully understand the mechanisms behind these benefits, the available evidence suggests that consuming cacao may be a simple and enjoyable way to improve overall health and well-being.
