Plant-Based Oils Linked to Lower Mortality Risk

A Mass General Brigham and Harvard-led study found that replacing butter with plant-based oils may reduce premature death risk. Analyzing dietary data from 200,000+ people over 30 years, researchers linked higher intake of soybean, canola, and olive oil to lower total, cancer, and cardiovascular mortality, while butter increased cancer and total mortality risks.

Key Findings:

• Higher butter intake → 15% higher death risk
• Higher plant oil intake → 16% lower death risk
• Replacing 10g butter with plant oil → 17% lower cancer and total mortality risk

Why It Matters:Plant-based oils are rich in unsaturated fatty acids, whereas butter contains saturated fats. Even small dietary swaps can yield meaningful long-term health benefits. Researchers plan further studies to explore biological mechanisms behind these effects.
