New Tools bring New Discoveries
New Tools - New Discoveries: The development of electron microscopes allowed us to see the minute detail of tissues in ways never before imagined. If body cells were in fact little mechanical machines that might have served us well. In surgery, which is a mechanical sort of process we know how far micro-surgery has developed.
So we saw deformed structures in cancer cells, and cholesterol in the blood vessels around the heart, and we jumped to conclusions about the causes of cancer and cardiovascular disease that are now being questioned.
Truth from science? Science can never be a source of unchanging truth. In the course of my life scientific understanding of many things have changed. However, with the internet, everyone can learn what the best new science is, and where there is disputed science too. It's better if we can use knowledge to reduce the barriers to our success. Many of the things we know and believe, and have acted on, are no longer scientifically valid. It's up to you to update your knowledge.
Old Nutritional Science: There was a research roadblock caused by the wide acceptance of the low-fat high-carbohydrate diet for 40+ years. When you are young, your body is carbohydrate tolerant, you can eat sugar and other carbohydrates with abandon and your body will cope with the excesses you subject it too.
Disputed Science: There is a long history of long and bitter battles in science to establish a better form of knowledge. We won't call it "scientific truth." In nutrition in the last 50 years there have been a growing list of outstanding professionals who have tried to stand against "the machine" and until now most of them have lost. But that can't continue. Denial of want we know is making too many people sick, and in all developed countries it's imposing a crippling cost on the health budget. That will stop.
Saturated fats were supposed to make people fat and clog the arteries. That's untrue. In the absence of insulin, saturated fats become the main fuel for your body. Vegetable oils were supposed to reduce our cholesterol and make us more healthy. Some of the modern vegetable oils produced for that purpose are cancer causing, especially if used for cooking. We are supposed to eat a low-fat high-carbohydrate diet, "a little bit of everything," and we were told fruit, vegetables and healthy whole grains were the best foods. That idea too is currently being challenged.
After fifty years of striving for low cholesterol, we discover that cholesterol doesn't matter. Higher HDL-Cholesterol is protective, and LDL-Cholesterol itself is probably harmless. Very small high-density particles may or may not be important.
However, “eating a little bit of everything in moderation” tends to get out of hand. We eat too many “healthy carbohydrates” and develop an intolerance for them. (Like a drug addiction.) Over the years we've produced too much insulin, created inflammation throughout our bodies, and become increasingly insulin resistant. Tell tale signs are increasing weight, high blood pressure, high fasting triglycerides, and low HDL cholesterol.
Given the size of that problem, in developed societies affecting about 75% of us, most traditional nutritional research is disappointing for me. The easy sources of funding, promotes research to reinforce the status quo, but you can see from the last 30 year results, it's going nowhere.
Banting Diet and Athletic Performance
For athletes, carbohydrate loading, suppresses fat oxidation for days, not just a few hours. Carbohydrates give you energy-dense glucose, and builds glycogen supply, but that's only 2000 kcal, and when that's burnt you are done. You “hit the wall.” Fat oxidation is disabled by your dietary practice.
The body stores about 40,000 kcal of fat fuel, and 2000 kcal of carbohydrate fuel.
Entering a long distance event, while in ketosis, gives you ready access to the 40,000 kcal of fat fuel, so your can run for hours, and glycogen is conserved so you are protected from “hitting the wall.”
