Strong Opposition
Older male rats get fatter than younger ones when they eat lots of sugary, processed carbs—and giving them DHA (a fish oil ingredient) doesn’t stop it, which means the extra weight gain isn’t caused by brain inflammation that DHA usually affects.

Dietary DHA prevents cognitive impairment and inflammatory gene expression in aged male rats fed a diet enriched with refined carbohydrates.
