The Claim
In healthy men consuming cholesterol-free diets, intake of omega-6 polyunsaturated fat does not significantly reduce high-density lipoprotein cholesterol levels when compared to intake of saturated or monounsaturated fat.
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.
In healthy men eating diets with no cholesterol, consuming omega-6 polyunsaturated fats does not lower HDL cholesterol levels more than consuming saturated or monounsaturated fats.
See the scientific wording
In healthy men consuming cholesterol-free diets, omega-6 polyunsaturated fat does not significantly reduce high-density lipoprotein cholesterol compared to saturated or monounsaturated fat, suggesting that the beneficial effect of polyunsaturated fat on LDL cholesterol is not offset by a reduction in protective HDL cholesterol.
When omega-6 fats are eaten, the liver makes more of a protein that helps carry good cholesterol in the blood, and less of a protein that moves cholesterol away from good cholesterol particles, so the good cholesterol levels stay stable.
What the research says
1 studyWhen men ate more omega-6 fats (like vegetable oils) instead of butter or olive oil, their 'good' cholesterol didn't drop—even though their 'bad' cholesterol went down. So, omega-6 fats help lower bad cholesterol without hurting the good kind.
