The company that brought you milk chocolate, Maggi instant noodles and Rocky Road ice cream is worried about your health. 

Nestle SA, the world’s largest food company, has joined the trend for personalised nutrition with a blend of artificial intelligence, DNA testing and the modern obsession with Instagramming food. The programme, begun in aging Japan, could provide the Swiss company with a wealth of data about customers’ wellness and diet as it pivots toward consumers who are seeking to improve their health and longevity.
