Genetic Link Found Between Starch Consumption and Dental Health Risks

Cornell study reveals how variations in the AMY1 gene influence oral bacteria and cavity risk after eating starchy foods.

Research from Cornell University highlights that the AMY1 gene, which affects starch digestion, plays a role in cavity and gum disease risk.
Individuals with higher AMY1 copy numbers break down starch more efficiently, fostering bacterial growth linked to dental issues.
The study found that starch consumption alters oral bacteria composition, with some species thriving in high-AMY1 environments.
AMY1 copy numbers vary widely among populations, influenced by historical diets rich in starch due to agricultural practices.
Findings suggest that personalized dental care may be beneficial, focusing on genetic predispositions to starch-related oral health risks.
