Healthy young adults can boost their working memory by increasing their intake of omega-3 fatty acids, according to a new study. During a six-month trial of people 18 to 25, "We found that members of this population can enhance their working memory performance even further, despite their already being at the top of their cognitive game," said researcher Bit Moghaddam, PhD.

Most similar studies have been done with elderly patients or people with medical conditions. Blood tests and memory tests prior to the study showed that the omega 3s the participants were getting from their diet had positive effects on their working memory. But after taking the daily supplement for six months, participants' scores on a test that required keeping track of letters and numbers had improved further.
