How Nutrigenomics Fights Childhood Type-2 Diabetes & Weight Issues

People vary in responses to food. What can scientists and researchers tell most family members about "healing nutrition" information to combat childhood type-2 diabetes or weight issues? How do you explain individualized, tailored, and customized nutrition in plain language to parents, children, and food retailers and to your own healthcare practitioner? Is it a scientific fact, metabolic reality, common sense, or cultural practice that reports of eating a lot of meat by a metabolic-typed carbohydrate type person might turn to fat, whereas eating mostly vegetables and fruits by a protein-type person might turn to fat because the carbohydrate-type person may be a slow oxidizer of sugar but the protein-type person may be a fast oxider of sugar? (Sugar perhaps would hit the bloodstream faster, causing spikes in insulin due to possible insulin resistance.) Tests can determine how you metabolize foods.Would a nutrigenomics-oriented genetic test of specific markers give clues? Or would measuring the insulin response after eating sweets reveal sugar spikes that a fasting glucose blood test might not show on paper?What's out there to learn about dangerous eating, food misinformation, and healing foods? Is it true that one person's dangerous foods are another person's healing foods based on metabolic and genetic body types? Is it true that specific foods turn into fuel for one person but become fat for another individual?
