Omega-3 Reduced Food Intake and DNA Damage in Mice on a Junk-Food Diet
This study looked at mice fed a “cafeteria diet” — a mix of high-fat, high-sugar, processed foods meant to mimic a typical Western diet — for 16 weeks, which led to weight gain, higher blood sugar, insulin resistance, and signs of DNA damage (genomic instability).
After the initial 16 weeks, some groups of mice received omega-3 supplementation or were switched to a standard diet for an additional 4 weeks. Researchers then measured body weight, blood markers, and DNA damage.
Mice given omega-3 while remaining on the cafeteria diet ate less food, gained less body fat, and showed lower blood sugar and less DNA damage compared to cafeteria-fed mice without omega-3. The researchers concluded that these improvements were largely explained by the omega-3 group eating less and carrying less body fat, rather than a direct effect of omega-3 itself.
What this means for you
In this animal study, omega-3 supplementation was linked to eating less and having less body fat on a junk-food-style diet, which in turn was associated with better blood sugar control and less DNA damage — suggesting that omega-3’s benefits here may work partly by helping to naturally reduce food intake and fat accumulation. As this was a mouse study, more research is needed to know whether the same pattern applies to people.
