Fish oils

A study has found that gerbils given a ‘cocktail’ of DHA, uridine and choline performed significantly better on learning and memory tests than untreated gerbils, and their brains had up to 70% more phosphatides (a type of molecule that forms cell membranes) than controls, suggesting that new synapses are forming. Some of the gerbils received all three compounds and some received only two; the improvements were greatest in those given all three. An earlier study had found that the treatment improved function in rats with cognitive impairment.

A mouse study has found that the diet of a pregnant mother, especially in regards to choline, can change the epigenetic switches that control brain development in the fetus. Pregnant mice received different diets during the period when a fetus develops its hippocampus. The genetic changes affected neurogenesis. The findings add to other research pointing to the effects of maternal diet on fetal development. Top sources of choline are eggs and meat. Fish and soy are also good sources.
