Scientists discover that eating fish makes you smarter, helps you sleep better


An apple a day might keep the doctor away, but one seafood meal per week could provide lifelong benefits including a higher IQ and better sleep. A new study conducted by scientists at the University of Pennsylvania demonstrated a clear link between the consumption of omega-3 fatty acids — most commonly found in fish — and heightened intelligence, as well as higher quality sleep.

The research was largely based on a huge sample study of over 500 children between the ages of 9 and 11. The children, of whom 54% were boys and 46% girls, provided information on their eating habits, including how often they consumed fish. Then they were asked to take an IQ test, and when the resulting data was matched up with their questionnaire responses, it became clear that a link exists between higher IQ and consumption of fish.

Similarly, the parents of the children in the study were asked to submit answers regarding each child’s sleep quality. The length of sleep, frequency of daytime napping, and other factors were included in the questionnaire. The data supported the notion that omega-3s, even when only consumed occasionally, do promote better sleep.

The study builds upon past research into omega-3s that linked the fatty acids to better quality sleep and higher intelligence, though no previous studies managed to link them all together at once. – READ MORE
