Omega-3s May Help Reverse Brain Effects of a High-Fat Maternal Diet in Offspring
This animal study looked at rat offspring whose mothers ate a high-fat diet during pregnancy and nursing. Previous research had shown that this kind of maternal diet leads to depression-like behavior and changes in myelin (the protective coating around nerve fibers) in the brain’s prefrontal cortex, effects that can last into adulthood.
Researchers wanted to know if giving the offspring an omega-3-enriched diet after weaning, continuing into adulthood, could reverse these effects. They measured behavior using a standard swimming test for depression-like symptoms and examined myelin-related proteins and brain cells using several lab techniques.
The omega-3 diet reduced the depression-like behavior seen in offspring of high-fat-fed mothers, without changing their general activity levels. It also restored normal levels of key myelin proteins (MOG and MAL) and normalized the number of myelin-producing brain cells in several brain regions. These effects were stronger in males than in females, with females showing more limited improvement.
What this means for you
This early-stage animal research suggests that omega-3 intake later in life may help offset some brain and behavioral changes linked to a mother’s high-fat diet during pregnancy, though these findings come from rats and would need to be confirmed in humans before any conclusions can be drawn for people.
