We searched Medline, Embase, CENTRAL and trials registries for RCTs comparing higher with lower LCn3, ALA, omega-6 and/or total PUFA, that assessed cancers over ≥12 months.

Many people–including many health experts–believe that omega 6 fats are considered an ‘essential fat’ and necessary in our diets. The fact is, omega 6 fats, which are polyunsaturated fatty acids—or PUFA’s, are made up primarily of linoleic acid, which is actually very harmful to our health.

We searched Medline, Embase, CENTRAL and trials registries for RCTs comparing higher with lower LCn3, ALA, omega-6 and/or total PUFA, that assessed cancers over ≥12 months. Random-effects meta-analyses, sensitivity analyses, subgrouping, risk of bias and GRADE were used. We included 47 RCTs (108,194 participants).
