Adventurer Bear Grylls’ healthy eating plan is absolutely nuts

We always knew Bear Grylls had balls — but this is ridiculous.

For many years, he lived as a vegan, existing on raw juices, vegetables and pulses.

But Grylls has now gone to the other extreme and lauded the health benefits of eating organs such as the liver, heart and even the testicles.

The adventurer, 48, said his diet was built around “grass-fed, good quality” red meat, raw dairy and fruit as well as organs. He steers clear of bread and pasta, and avoids processed foods.

The former soldier has even put his face to a dietary supplement range that includes “beef thyroid” and “beef lung”.

“The way I build all of my meals is around … good quality red meat,” he said in an online video. “I always throw in a bit of liver as well every few days.”

He said that he had been convinced by research that proved “we need red meat” and “how nutrient dense liver” is.

Grylls hailed the Ancestral Supplements range saying: “We need more organs than just the liver. We should be eating pancreas and heart and testicles.

“All that is so good ancestrally and naturally, but that combination is how I eat, how I try my best to stay strong. I hope it helps you.”
