A comprehensive Harvard study following 120,000 people over 30 years has weighed in on the contentious seed oils debate, finding that moderate consumption of common vegetable oils is not associated with increased inflammation or disease risk.
Study Findings
- 120,000 participants tracked for 30 years
- No link between moderate seed oil consumption and heart disease
- Canola and soybean oil showed neutral health effects
- Olive oil still showed superior benefits
- Deep-fried foods remained harmful regardless of oil type
Expert Interpretation
The study suggests the anti-seed-oil movement popular on social media is largely unfounded. However, experts still recommend olive oil as the primary cooking fat and limiting deep-fried foods regardless of oil type.
