How are MY FOODBOOK and blood sugar related?

MY FOODBOOK is a personalized nutrition program often based on DNA tests or food sensitivity tests. Its relationship to blood sugar is indirect and not well-supported by evidence. Some genetic variants (e.g., PPARG Pro12Ala, APOA5 rs662799) have small effects on insulin sensitivity or triglycerides, but they are insufficient to prescribe a specific diet. Most claims are marketing. Blood sugar is best managed through validated methods like continuous glucose monitoring, HbA1c, and dietary adjustments based on individual response. The evidence is weak; do not rely solely on a foodbook.
