Scimex: An Australian-led study has shown, for the first time in mammals, the
diets that contribute to longevity and reproductive success in mice. The
researchers found that while a strict high carbohydrate and low protein
diet achieved greater longevity, diets that helped reproductive success
varied in their protein and carbohydrate ratios; with a healthy sperm
count requiring equal amounts of protein and carbs, and an optimal
reproductive cycle achieved on a higher carb diet in female mice.
