Myths vs facts: MY FOODBOOK and Haut

Myths vs facts: MY FOODBOOK and skin. Many believe a DNA-based nutrition plan ("foodbook") can directly cure skin issues like acne or wrinkles. Fact: Genetic variants such as rs1800012 (collagen metabolism) may offer clues about skin properties, but evidence for personalized nutrition as a standalone solution is weak. A foodbook provides hypotheses, not diagnoses. Studies indicate that factors like cortisol (stress) and intestinal permeability ("leaky gut") affect skin – yet these are not reliably measured in typical foodbooks. Clinical validation is lacking. Bottom line: A foodbook can motivate healthier eating, but it is not a medical skin therapy. For real skin concerns, consult a dermatologist.
