Ms. Cross,

Your article is actually dangerous in saying we should ignore cholesterol. All the medical literature supports the cholesterol hypotheses. Here is a question for you - what is the single type of food that elevates serum cholesterol the most? Hint - it is not exogenous cholesterol which dont do nothing to alter serum cholesterol levels. Knowing one's lipid numbers is critical and in the grand scheme are more important than homocysteine levels (which are rrely .measured). I am an anti-statinist, so IMO, diet and exercise is the best way to deal with an elevated LDL.

As to homocysteine, it is no medical secret. It has been known about since the late 60s - see reference. Unfortunately, the significance of what was then a theory, now a fact, was ignored - not uncommon in medical practice.


Instead of worryng about dietary sources of the necessary B vitamins, it is much more effective, consistent and feasible with daily supplementation of these vitamins. No mess, no fusss, consistency guaranteed. Two of the missing subjects taught in medical schools are the use of supplements and the teaching that aging is a disease process amenable to intervention.

I find it sad that to promote one useful concept (All the medical literature supports the deleterious role of homocysteine), you put readers at risk with your deplorable title. Cholesterol is one substance we should not forget. In fact, the qualification of cholesterol has advanced in exciting ways with measuring lipoprotein size and measuring LpA (see reference)


You are enthusiastic and intelligent - you seem though to have an anti-cholesterol bias ignoring its well-and-thoroughly documented role in vascular disease.
