The Claim
Among women aged 40–60, daily intake of partially hydrogenated vegetable oils is associated with higher systemic inflammation compared to daily intake of non-hydrogenated vegetable oils, despite comparable quantities consumed.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Women aged 40–60 who consume partially hydrogenated vegetable oils have higher levels of systemic inflammation than those who consume the same amount of non-hydrogenated vegetable oils.
See the scientific wording
Among women aged 40–60, daily intake of partially hydrogenated vegetable oils (mean 23 g/day) and non-hydrogenated vegetable oils (mean 22 g/day) are comparable in quantity, yet show opposing associations with systemic inflammation, suggesting that oil type, not just quantity, may influence inflammatory status.
Eating partially hydrogenated oils introduces trans fats into the body, which damage the lining of blood vessels and trigger immune cells to release inflammatory chemicals that spread through the bloodstream.
What the research says
1 studyWomen who ate more hydrogenated oils (like margarine) had much higher levels of body inflammation, while those who ate more regular plant oils (like olive or canola) had lower inflammation—even though both groups ate about the same amount of oil. This means what kind of oil you eat matters more than how much.
