What our evolutionary history can teach us about eating well

September 25, 2026 · 34 min

Show notes

These days, supermarket shelves are filled with thousands of different products all vying for our attention; the options are almost endless. However, if we look back in time, we find that our early ancestors simply ate what they were able to hunt and gather and eventually farm. Thanks to the huge number of options we now have available, many of us choose to follow diet plans of various kinds, be it veganism, low-fat, low-carb, or the paleo diet, but what can we learn from evolutionary history about what we should really be eating if we want to live longer, healthier lives?

In this episode we’re joined by Prof Daniel Lieberman, an author and evolutionary biologist based at Harvard University, to talk about his latest book, Fed Up – What Evolution Reveals about Food, Diet and Eating Well.

He tells us why many of us find it so difficult to eliminate certain foodstuffs from our diets over the long-term, how humans evolved to store more body fat than other mammals, and why the good news is that humans are perhaps nature’s ultimate omnivores.
