18. Genetic Adaptation to Processed Foods
The global shift toward highly processed foods is introducing new evolutionary pressures on human metabolism. As diets rich in sugars, fats, and additives become widespread, gene variants affecting obesity risk and metabolic health may undergo selection. Some researchers suggest that populations regularly exposed to processed foods could evolve adaptations for more efficient processing or resistance to negative health impacts. These metabolic changes may shape future generations, reflecting the deep interplay between our genes and modern lifestyles. Nature article
