The Inuit are the indigenous people of Greenland as well as northern Canada and Alaska. Since the 1970s, we have been told that the Inuit’s traditional high-fat, low-carbohydrate diet is healthy. Today, advocates of the “keto” and “Paleo” diets make false claims about the Inuit diet. In reality, the Inuit who were eating their traditional diet did not go into ketosis unless they were fasting. Also, the Inuit have always had a short lifespan. That fact was obvious to the earliest Europeans who studied them.
The food industry has been urging me to eat fish. The supplement companies have been urging me to take fish oil supplements. They claim that omega-3 fatty acids prevent heart attacks. Some people even claim that pregnant women need to eat fish or fish oil. But in reality, green plants are an excellent source of the essential omega-3 fatty acid. This could explain why people who rarely if ever eat fish can have healthy hearts and healthy brains. In fact, the healthiest populations are the ones that eat very little fat of any kind and lots of vegetables.
