Soybean Oil
Listed as a source of omega-3 ALA (0.31 g per 1 tsp) and vitamin E (1.1 mg per 1 tbsp, 6% DV)
Why It Matters for Longevity
Listed as a source of omega-3 ALA (0.31 g per 1 tsp) and vitamin E (1.1 mg per 1 tbsp, 6% DV) Plant oil with ALA omega-3 and vitamin E. Soybean oil has an omega-6 to omega-3 ratio of ~7:1; excessive use relative to olive oil may promote inflammation; canola or walnut oil provide better omega-3 balance (PubMed) Soybean oil vitamin E (primarily gamma-tocopherol) has antioxidant properties; however, high linoleic acid content may increase lipid peroxidation at cooking temperatures (PubMed)
How to Use It
Pairs well with vegetables, tofu, salad greens. Use as a oil in your daily meals according to the Longevity Diet guidelines.

Synergies
- Olive Oil (antagonism): Olive oil is the preferred cooking fat in Longevity Diet; soybean oil's high omega-6 content makes it a less favorable alternative - Omega-3-Fatty-Acids (complement): ALA in soybean oil contributes modestly to omega-3 status; best used sparingly alongside marine omega-3 sources - Walnut-Oil (complement): Both are plant-based omega-3 containing oils; walnut oil has a more favorable omega-6:omega-3 ratio
Flavor Profile
Taste: neutral, very mild. Aroma: neutral, faintly beany. Texture: liquid, light. Category: cooking oil.
The Science
- PubMed: Soybean oil has an omega-6 to omega-3 ratio of ~7:1; excessive use relative to olive oil may promote inflammation; canola or walnut oil provide better omega-3 balance - PubMed: Soybean oil vitamin E (primarily gamma-tocopherol) has antioxidant properties; however, high linoleic acid content may increase lipid peroxidation at cooking temperatures - Book claim (medium confidence): Listed as a source of omega-3 ALA (0.31 g per 1 tsp) and vitamin E (1.1 mg per 1 tbsp, 6% DV)
Key Nutrients
| Nutrient | Per 100g | Notes |
|---|---|---|
| ALA (omega-3) | 6.8 g | Plant form; ~5–15% conversion to EPA/DHA; lower efficacy than marine omega-3s |
| Linoleic acid (omega-6) | 51 g | Very high omega-6; unfavorable ratio when used as primary cooking oil |
| Vitamin E | 8.2 mg | Primarily gamma-tocopherol; antioxidant; degrades with high-heat cooking |
