MONDAY, July 1, 2002 (HealthDayNews) -- If you like to eat fish, there's a new study that suggests its health benefits may be greater than previously known.

Researchers studying neighboring tribes in Africa -- one that ate a diet high in fish and the other that was primarily vegetarian -- report that the fish eaters had lower levels of a hormone associated with appetite.

The study, published in tomorrow's edition of Circulation, says that levels of leptin, released when hunger is satisfied, were lower in the fish eaters, regardless of body weight. Researchers say they think that when levels of leptin get too high, the body ignores the signal it sends to stop eating.

Although the findings are similar to other studies, researchers say that any practical application of them is unclear.
