What you eat is like code: it signals your body to turn on health genes or disease ones …more

what it claims

Optimize your vitality and positively influence your gene expression by adopting a diet rich in phytonutrients, healthy fats, and spices, while strategically structuring the order of your meals to slow down sugar assimilation.

The concept of nutrigenomics, according to which food sends signals to our genes, is a serious field of study supported by research journals like that of ResearchGate (2025).

The concept of nutrigenomics, according to which food sends signals to our genes, is a serious field of study supported by research journals like that of ResearchGate (2025). Furthermore, the tip of saving chocolate for the end of the meal to regulate sugar assimilation and energy is solidly validated by randomized controlled trials (RCTs) published in Clinical Nutrition. Regarding rosemary for memory, small RCTs conducted by the University of Northumbria show slight positive effects on recall and attention. Nevertheless, the claim that this routine allows one to feel "40 years younger" is a purely subjective extrapolation and impossible to measure. Finally, the influence of diet on vitality is rooted in long-term consistency, not the isolated effects of a single typical day. This colorful and balanced plate, however, remains an excellent model for taking care of one's body on a daily basis.

What the graded evidence says

Effect
postprandial glucose incremental AUC (0-180 min) — ~53% lower with carbohydrate-last vs carbohydrate-first (T2D crossover, n=16); vinegar and post-meal walking each give small-moderate reductions
Measured on
mainly adults with type 2 diabetes or overweight; fewer data in healthy normoglycemic adults

What’s uncertain

Most trials are small, short-term, and done in people with diabetes. For someone with healthy blood sugar, a flatter curve is nice but hasn't been tied to weight or long-term outcomes. It never replaces total food quality and quantity.
