What to watch with MY FOODBOOK and Blutzucker?

Combining MY FOODBOOK (a digital food diary) with blood glucose monitoring (e.g., CGM) can help identify individual glycemic responses to meals. The evidence is moderate: studies show that continuous glucose monitoring paired with dietary logs improves blood sugar control in people with and without diabetes. However, individual variability is high – factors like daily stress, sleep, exercise, and gut microbiome influence glucose more than single DNA variants. Genetic markers such as PPARG (rs1801282) or TAS2R38 (bitter taste) have only small effects on insulin sensitivity or eating behavior. MY FOODBOOK is a commercial tool; its underlying algorithms are often not transparent. Be cautious not to fall into a 'glucose optimization trap' where every food is demonized. Use the data as guidance, not dogma. If values are abnormal or you have pre-existing conditions (e.g., diabetes), medical supervision is recommended.
