Research has only begun to unearth the potential in understanding the human microbiome, but the outlook is amazing. Innovative startups and research labs are developing solutions that use bacterial samples from your gut to profile your body's reaction to the foods you eat. In the not too distant future, expect to see a world where our "gut type" can be catalogued similar to our blood type. Armed with such personalized and actionable information, consumers will demand better products and services from the food and drink industry, presaging significant advances in human health and nutrition.
