The deeper explanation
The answer in detail
Genes, gut microbes, sleep, activity, medication and metabolic health alter digestion and blood-sugar responses. Individual variation does not erase the value of broad dietary evidence.
Why it matters
Diet influences lifelong health, while the food system determines whether healthier choices are affordable and convenient.
The public system around two people respond differently to the same meal
Pharmaceutical incentives, diagnostic capacity and household income affect who receives effective care and how quickly evidence becomes practice.
The consequences reach public budgets and workplaces: prevention can reduce later costs, while unequal access shifts illness and lost work onto families and communities.
