    High cholesterol low heart disease – The Sami Empty High cholesterol low heart disease – The Sami

    "(Of course, it is a paradox…. Paradox number 112, or thereabouts)

    As a nod to a regular contributor to this blog, who lives not far from the area, I thought I should write about the Sami. When I was younger we would probably have called the Sami ‘Eskimos’ – because anyone who lived north of the Arctic circle and dressed in fur was, clearly, an Eskimo. This term is now, I believe, a dread insult. A bit like calling a Scotsman an Englishman, or an Austrian a German. Or, I believe, a Canadian an American. Wars have been fought over less.

    The Sami, unlike the Inuit, who reside mainly in North America, live in the North of Scandinavia: Northern Sweden, Norway and Finland and suchlike. In what used to be called Lapland. However, we now call the Lapps, the Sami (please keep up), so do they live in Samiland?

    What I know about the Sami is that they obviously enjoy the cold, eating reindeer and smoking. They must do other things too, but I am not entirely sure what. This makes them very similar to the Inuit, who also enjoy: the cold, eating seals, caribou, and smoking. Neither the Sami, nor the Inuit, have the least interest in eating vegetables. I suppose there may be the occasional frozen carrot – or suchlike – from Iceland (that is a UK based joke).

    Apart from not eating vegetables, smoking, and eating lots of fat, the Inuit and the Sami have one other thing in common. You can probably guess what it is. Yes, they both – those that live a traditional lifestyle anyway – have a very low rate of death from heart disease.

    This came to my attention during an e-mail discussion I was having about whether the human brain required any glucose – at all. Those taking part were the usual suspects, Richard Feinman, Gary Fettke, Nina Teicholz, Jimmy Moore, Jason Fung, Tim Noakes etc. [Yes, good bit of name dropping there].

    The consensus was that the human brain could use Ketone bodies for much of its energy requirement. However, there was an absolute need for about forty grams of glucose per day. The final statement on this matter, the one everyone seemed to agree on anyway, was as follows:

    1)     The brain requires no dietary glucose. It has a requisite use of 40 grams/day, but these grams can easily be provided from glycerol, and normal ingestion of not particularly high amounts of protein in a high fat, zero carbohydrate diet.

    2)     But this is a time dependent situation. Short term fasting will not be a problem for most otherwise healthy people. However, more prolonged starvation will eventually kill you as the brain will pirate 40 grams of glucose/day from protein and lipid, until you have neither fat stores, nor adequate diaphragm or heart muscle left to survive.

    Don’t worry, there were about a thousand papers quoted in creating these statements, so the science seems robust. This discussion started because I had an interest in how hunter gatherers, who ate no carbohydrates, kept their brains going. What was the mechanism by which the Massai, Inuit and Sami, power their brains with glucose, if they don’t eat any carbohydrates?

    Well, it seems that you can get a certain amount of glucose from fat. Fat is made up of triglycerides, and each triglyceride contains three fatty acids and one glycerol molecule. Two glycerol molecules stuck together (by the liver) makes one glucose molecule.

    In short, pure fat does contain some glucose, which can be used to power the brain. However – assuming you are eating no carbs – the brain requires more glucose than can be provided by the glycerol held in triglycerides. Thus, you still need to convert some dietary protein into glucose. If you are not eating any food at all, the body will need to break down muscle to get at the protein required to synthesize glucose.

    To cut a very long story short, the end point of the discussion was an agreement that you do not actually need to eat any carbohydrates to remain heathy. The body, and the brain, can get all the glucose it requires from glycerol and dietary protein.

    The reason why I was interested in this issue was that ‘the absolute need for carbohydrates’ is a ‘fact’ that is thrown at me from time to time by ‘experts.’ I have always known they were wrong, because there are people e.g. the Massai, who never eat any carbohydrates, and remain far healthier than any expert I have ever cast my eyes upon. However, I wanted to be sure of the facts. ..."
