How Does Cacao Boost Brain Power?
How Cacao Improves Cognitive Function
Cacao, the main ingredient in chocolate, contains compounds that can enhance cognitive function in several ways:
Flavanols
Cacao is rich in flavanols, a subclass of flavonoids that have been shown to improve cognitive performance. Flavanols can:
- Increase cerebral blood flow and oxygenation, improving brain function
- Enhance working memory and attention, even within a few hours of consumption
- Protect against age-related cognitive decline and neurodegenerative disorders
Theobromine and Caffeine
Cacao contains small amounts of stimulants like theobromine and caffeine that can:
- Boost alertness, mood, and cognitive function
- Reduce mental fatigue and improve performance on demanding cognitive tasks
Antioxidants
The antioxidants in cacao can:
- Protect brain cells from oxidative stress and inflammation
- Promote neuronal function and brain connectivity
Gut-Brain Axis
Cacao polyphenols are metabolized by gut bacteria into compounds that can:
- Cross the blood-brain barrier and directly protect brain cells
- Increase levels of neurotrophins that support neuroplasticity
Regular intake of cacao and dark chocolate has been found to:
- Improve general cognition, attention, processing speed and working memory
- Reduce symptoms of age-related cognitive dysfunction
- Provide greater benefits for those with lower diet quality or mild cognitive impairment
However, more research is still needed to determine the optimal dose and formulation of cacao for cognitive benefits. Moderation is also advised as chocolate is high in calories, sugar and fat. But overall, the evidence suggests cacao can be a valuable addition to a brain-healthy diet and lifestyle.
