The science of Cacao
Peer-reviewed research shows that real cacao — especially high-flavanol cacao — has measurable effects on health: 
• Better blood vessel function & circulation — helps arteries stay flexible, even after sitting for long periods. 
• Reduced inflammation — daily cocoa extract was linked to lower key markers of body-wide inflammation in older adults. 
• Skin hydration & wrinkle support — people in a 12-week trial had better skin moisture and fewer signs of aging. 
• Brain focus & efficiency — cacao polyphenols helped the brain work more efficiently during demanding tasks. 
💡 These benefits are tied to compounds naturally present in cacao (flavanols/polyphenols).
Eating highly processed chocolate with lots of sugar won’t give you the same effects.
