New research suggests that tailoring diets to an individual’s DNA profile could aid in managing blood sugar levels and reducing the risk of type 2 diabetes, especially among high-risk individuals. A pilot study involving 148 participants combined genetic profiling with personalised dietary advice, resulting in significant improvements in blood glucose control compared to traditional dietary interventions.
While highlighting the potential benefits of using genetic data to customise health interventions, further extensive trials are required to validate these findings. Diabetes, a chronic disease affecting blood glucose handling, includes a reversible prediabetes stage. Lifestyle changes, such as improved diet and exercise, can significantly reduce the progression from prediabetes to type 2 diabetes. However, these measures can be costly and labor-intensive. Genetic markers are recognised for their potential in predicting an individual’s susceptibility to chronic diseases related to diet.
