Myths vs facts: MY FOODBOOK and fertility

The question of myths vs facts regarding MY FOODBOOK and fertility requires honest assessment. MY FOODBOOK is a personalized diet book based on DNA test results offered by MyBody-X. It provides general dietary recommendations targeting genetic variants (e.g., carbohydrate metabolism, lipid metabolism). However, there are no specific, validated studies showing that such a DNA-based diet book improves fertility. The evidence for nutrigenetic diet personalization is overall weak (PMID:37813841). Fertility is influenced by many factors: hormonal status, age, lifestyle, diet, weight, stress, and medical conditions like PCOS or endometriosis. A balanced, nutrient-rich diet is certainly beneficial, but personalization via a single gene panel is not scientifically robust. Additionally, IgG-based food intolerance tests (like NutriCheck) are rejected by medical societies as diagnostic tools. MY FOODBOOK may serve as a motivational guide, but claims that it directly boosts fertility are more marketing than evidence-based medicine. Consumers should maintain realistic expectations and not rely solely on such a book.
