Cooked starchy foods may impair male fertility

When starchy foods are cooked at high temperatures, such as french fries and potato chips, a reaction between asparagine and glucose can lead to the production of acrylamide.

Acrylamide is a known carcinogen.

A recent study has found that rats given 20 mg of acrylamide/kg body weight per day for 28 days had a decreased sperm count as well as an increased dead sperm count.

Animals that received Vitamin E with the acrylamide had similar effects, but to a lesser degree.

The incorporation of Vitamin E also seemed to promote recovery.
