Genetic Mutation Linked to Reduced Sugar Cravings

A study reveals that variations in the sucrase-isomaltase gene may affect our preference for sugary foods.

Research led by the University of Nottingham identifies the sucrase-isomaltase (SI) gene as influencing sugar preferences.
Individuals with a non-functional SI gene consume significantly less sugar due to difficulty digesting sucrose.
The study involved 6,000 participants from Greenland and nearly 135,000 from the UK, highlighting genetic differences in sugar consumption.
Findings suggest potential for developing treatments targeting the SI gene to help reduce sugar intake and combat obesity and diabetes.
The research also connects genetic defects in sugar digestion with irritable bowel syndrome, affecting dietary habits.
