A diet rich in phytosterols reduces testosterone levels and activity of enzymes that metabolize testosterone into more active forms. The study suggests a potential link between plant-based fats and lower rates of hormone-dependent cancers.
A study of 42 women found that maternal folate status during extended lactation was sustained by supplementing with 1 mg folic acid per day. This supplementation helped maintain plasma and milk folate levels as well as hematocrit, but had no effect on unsupplemented women.

A new University at Buffalo study found that body mass index, refined sugar, and saturated fat intake are directly associated with the formation of gallstones. Conversely, physical activity and a diet high in monounsaturated fat and insoluble dietary fiber were protective against gallstones.
A survey of consumers found that Americans prefer beef over emu due to its gamey flavor, although it is a healthier option. Emu was rated lower in tenderness and overall acceptance compared to turkey and beef.
