This is part 10 of my review in Layman's terms of the book 'The Art and Science of Low carbohydrate Living' By Jeff S. Volek, PhD, RD & Stephen D. Phinney, MD, PhD
note: This again is a very long and informative chapter, so I have split the review of this chapter into two parts as with the Insulin Resistance chapter.
A doctor will give a prescription as soon as your Cholesterol rises by the smallest amount, even though in the last decade the lesson has been, total cholesterol is not the only thing to look at with health. This chapter is about dietary intervention and helping to reduce heart disease. Statin drugs may reduce LDL;s (Low density lipoproteins) but the proof is not there that it reduces the risk of cardiovascular disease, is the wrong target being aimed at?
Lipoproteins are particles traveling through the blood stream delivering lipids to the cells. In the center of teach particle are the lipids, fat substances like cholesterol, triglycerides, phospholipids and proteins that are surrounded by a water-soluble substance so it can travel easily through to watery blood.
LDL-C (low-density lipoproteins)- carries these particles from the liver to organs throughout the body
HDL-C - (high-density lipoproteins) - does the opposite, the particles travel back to the liver to be disposed of.
Between 1950 and 1970 it was assumed saturated fats caused high cholesterol which caused heart disease, this hypothesis still stands after over 40 years, is it correct?
LDL Response to a Low Carbohydrate Diet
In studies LDL's can rise , fall or stay the same on a low carb diet, but the question is, is this a problem! Quite often the LDL will rise and this is why many doctors will recommend a low fat diet which without Statin use the LDL's will do the same , rise , fall or stay the same. Now I have completely confused you!
Factors to consider;
1/ A study in 1994,' the Lyon Diet Heart Study', revealed after 27 months (at which time the study was abruptly cancelled) showed a dramatic decrease in mortality in the group on a high fat diet as opposed with the participants on the "American Heart Association' diet (low fat). Even though there was the massive benefit for reduced heart disease (on high fat-low carb) there was no advantage to lowering the LDL
