The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

This paper reviewed the literature on the association of vitamin D and peripheral arterial disease.

The review found:
(a) People with lower vitamin D levels are more likely to develop peripheral arterial disease.
(b) Higher amputation rates are observed among patients with peripheral arterial disease and lower vitamin D levels.
(c) Vitamin D deficiency is significantly associated with increased risk of cardiovascular adverse events.

This study shows that vitamin D deficiency could be an independent risk factor for the development of peripheral arterial disease.

By far the richest source of dietary vitamin D is cod liver oil. The second richest source of vitamin D is lard. Other foods containing vitamin D include: Butter, egg yolk, liver, organ meats and seafood. Vitamin D is virtually absent from all plant food.
