A study published in the medical journal Acta Paediatrica reveals that eating fish on a regular basis increases the adolescent IQ.
According to Kjell Toren of Sahlgrenska University Hospital in Gothenburg, Sweden, the young 15-year-olds attained 7% higher cognitive test results than average when fish was consumed once a week. Test results increased by 12% when the teen participants ate fish more than once per week.
Several previous studies have demonstrated that omega-3 fats, which are abundantly found in certain fish, may promote brain development and function.
