PCR has enabled personalised genome testing. An industry has sprung up offering consumers tailor-made products and services based on information in their genome. For example, nutrigenomics is a specific form of consumer genomics linking genetic information to information about foods that might be better or worse for particular conditions, like inflammatory bowel disease.
Food for thought:
How could you be sure the products are really useful? How could you be sure the product claims are scientifically reliable?
