The definitive guide to using your recent ancestry to determine your optimal diet. Go back a few million years. The Definitive Guide to Using Your Recent Ancestry to Determine Your Optimal Diet.

Go back a few million years, and we all share a common ancestor.

Some Hursuit hominids scrounging for grubs, digging up grassy sedge tubers, cracking bones,

and scaring lions away from their kills on the African grasslands with primitive but

effective tools and the most advanced linguistic abilities the planet had yet seen.

Since then, humans have spread across every environment imaginable and adapted to those environments.

Much remains the same. We all breathe oxygen, require protein, produce insulin,

oxidized fatty acids. But extended stays in unique environments have created genetic proclivities

in different populations. For example, descendants of people who settled in high altitude areas

like the Himalayas,

the Andes, and the Ethiopian highlands, tend to show greater resistance to low-oxygen environments,

while the Greenland Inuit show unique adaptations to cold environments, including increased activity of heat-stimulating brown fat.

And among the island dwellers of Sardinia, where the

landscape constrained the amount of available food, there's considerable evidence of positive

selection for short stature. What other differences exist, and how can we explore them to

inform and improve our own diet and lifestyle choices.

One way is to directly test your genes using a service that analyzes your DNA and provides

gene-based dietary exercise and lifestyle advice.

When I got my genes analyzed by DNA fit, my current diet and lifestyle choices, avoiding chronic cardio, eating

more fat, taking more vitamin D or sun, and omega-3s, were vindicated.
