Why is this so important? Well, high blood glucose is a serious situation that the body has to rectify as a priority. High levels of blood glucose cause circulatory problems and damage to the inside wall of blood vessels. And a high level of blood glucose triggers the release of the hormone insulin, which is required to lower blood glucose levels.
Insulin enables the body’s cells to use some of the glucose, but if there is too much glucose insulin converts the excess glucose into fat (triglycerides). This explains why low-fat /high-carbohydrate diets increase blood triglyceride levels.
It is worth mentioning that the presence of a high level of insulin, in response to the high glucose level, by definition, blocks the ability to burn body fat. Insulin is a fat storing hormone. This is one reason my people who follow a low-carbohydrate diet tend to lose more body fat.
When the level of triglycerides is high we also find a low level of HDLs - the so called ‘good cholesterol’. Again, every single dietary trial completed has found that a low-fat / high-carbohydrate diet reduces HDL levels.
We can really start to appreciate the topsy turvy world we live in where HDLs are called ‘good’ and at the same time low-fat diets are promoted as healthy - the very diet that is the best way to reduce HDL ‘good cholesterol’ levels. Just one of the many fundamental inconsistencies associated with the lipid hypothesis.
