Genetic testing has gained a lot of popularity in the past decade through ancestry companies who can test your DNA and track your family’s history. But genetic testing can be used for a lot more than seeing where you came from, and can be used a lot more proactively as well. Genetic testing can tell you how your body functions, right down to the cellular level, and can help you understand how your body processes nutrients, how it metabolizes caffeine, how well it handles inflammation, and much more. It can help you look forward to a healthy future as well as backwards to your ancestors.
