Deep dives
The Importance of Omega-3 for Brain Health
Omega-3 fatty acids are crucial for brain development and overall health, representing over 50% of the brain's fat composition. Humans cannot produce omega-3s naturally, making dietary intake essential to avoid health complications. Low levels of omega-3s in populations have been linked to significant health issues, including neurodegenerative diseases like Alzheimer's. This necessity has led to the rise of a multi-billion dollar omega-3 supplement industry that claims to improve memory and mood, though the efficacy of these claims varies.
