Artificial intelligence could help work out the best diet for every individual

Is broccoli or beetroot the best option for your personal health? Which foods are likely to trigger the biggest glucose spikes or cholesterol surges in your blood? Custom diets are the next frontier in nutrition science – and artificial intelligence (AI) will play a key role in figuring out what each of us should, and shouldn't, be eating. An ambitious program called Nutrition for Precision Health (NPH) kicked off in the US in January 2022 when the National Institutes of Health (NIH) awarded $170 million to fund institutions across the country to conduct a five-year study with 10,000 participants. CNN spoke to Holly Nicastro, program director in the NIH office of nutrition research and coordinator of NPH, about the aims and scale of the project and how AI can benefit our health by helping to devise optimal diets for every individual.
