Some truth in it, which can start you thinking. Many people have read Jack London’s stories of the Gold Rush in the Canadian Far North, so descriptive of the long winters and hardships etc. The fact is, he was only in the area for a few months. Contracted scurvy from poor food choices (and probably too much alcohol), got sick with his teeth falling out, and had to be transported back to the Lower 48 via steamboat from St Michaels, Alaska, way down the Yukon River.
Also the Athabascan Indians of Interior Alaska often starved in the winters. Their food was the original “Atkins Diet”–berries (IF they gathered and dried them during autumn), fish (again, usually dried for winter when the ice was too thick to catch any–we’re talking 4ft thick in winter), and game (usually lean, IF they could locate any.) I suspect much of it was from malnutrition (lack of vitamins, minerals and carbs) and not always lack of snowshoe hares and the occasional winter moose. Once the white men introduced alcohol, many Native cultures starved and spiraled down, due to not taking the time and hard work to prepare for winter. (In the late 1800’s the Inuit of the coast were almost wiped out due to “The Sleeping Time” when everyone drank themselves into a coma instead of prepping for winter.)
We see a lot of diabetes among the people of India, simply because they eat mostly white rice.
That is why one of our preps is multivitamins with minerals. Can tide you over when certain things are scarce. And plan to have some perennial fruits/veggies/herbs that supply our needs.
Several other things in the article were also food for thought. Nuclear plants, for instance. We just have to do what we can to survive, and trust God for the rest. Life is terminal anyway, sooner or later.
