In a recent study, 60 kids whose biopsies revealed a fatty liver took 250 mg of DHA (docosahexaenoic acid) per day, 500 mg of DHA per day or a placebo. After six months, doctors used ultrasound to measure liver-fat content. Compared to placebo, those who had taken either dose of DHA had less severe fat buildup in liver cells, greater insulin sensitivity and lower total blood fat levels. Doctors said prior studies had found DHA has anti-inflammatory and insulin-sensitizing effects and believe DHA stimulates the genes that control insulin sensitivity and blood sugar metabolism.
