That is exactly what Sir David Attenborough said “It’s a time warp without parallel”.

Interesting that in that era they knew little about nutrition, most of the advances in sports nutrition have been made quite recently, but they hit upon the fact, that to maximise slow burn enery over a long period, you need fat - which has the highest ratio of calories to weight, and does not produce the blood sugar spikes associated with higher glycaemic foods.

I met ranulph fiennes , and he too used high fat butter and so on.

I visited the Museum of Brands, Packaging and Advertising in London at the weekend. They have Edwardian adverts for plasmon biscuits, proudly proclaiming their use on the Antarctic expeditions and reinforced by an illustration of a British expedition happily tucking into them.
