A new study by Japanese researchers has demonstrated a strong preventive effect of B vitamins against various types of dementia. The most powerful results were shown by riboflavin: its regular intake almost halved the risk of developing cognitive impairment. The findings were reported by eatingwell.com.

The study involved 4,000 middle-aged and older participants whose health and lifestyle were monitored over a 15-year period. Particularly insightful was the analysis of dietary habits and their long-term effects on health. A clear pattern emerged — the highest dietary intake of vitamins B2, B6, and folic acid reduced the likelihood of developing dementia by nearly half, by 49%.

Experts emphasize that this effect is preventive, not therapeutic, highlighting the importance of a balanced diet.

Natural sources of riboflavin include dairy products, eggs, and beef. Vitamin B6 is abundant in bananas and seafood, while folic acid is found in leafy vegetables and legumes. The study authors recommend regularly incorporating these foods into the diet to provide natural protection against age-related cognitive decline.
