Researchers at Simon Fraser University have made a groundbreaking discovery, suggesting that folic acid may reduce the risk of autistic-like behaviors in children exposed to lead during pregnancy.
Key Findings:
- Folic acid supplementation (0.4 mg/day) may mitigate lead’s neurotoxic effects.
- Low folic acid intake (<0.4 mg/day) strengthens the link between blood-lead levels and autistic-like behaviors.
- High folic acid supplementation (>1.0 mg/day) shows no additional benefits.
The Study:
Analyzing data from 2,000 Canadian women (MIREC study, 2008-2011), researchers measured blood-lead levels and folic acid supplementation during pregnancy. Children’s autistic-like behaviors were assessed using the Social Responsiveness Scale.
Implications:
- Folic acid’s neuroprotective effects align with Health Canada’s recommendations.
- Proper supplementation may lower autism risk associated with lead exposure.
- Study supports existing guidelines for folic acid intake during pregnancy.
