Fish Is Brain Food
"The old claim that eating fish makes you smarter or improves brain function."
Backed by real, substantial nutrition science. DHA, an omega-3 fatty acid found in fish, is a major structural component of brain cell membranes, and the brain's ability to communicate between cells depends on it. Children of mothers who ate more fish during pregnancy show measurable improvements in verbal intelligence and motor skills, and in older adults, higher omega-3 levels are linked to larger brain volume and up to a 50% lower risk of developing dementia. One honest caveat: while fish itself shows real benefit, taking fish oil supplements instead hasn't consistently shown the same protective effect in clinical trials, suggesting it isn't simply about the isolated compound.
