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 study investigated the association between cholesterol levels and memory function. The study included 193 participants, aged 80 and older.

Regarding LDL cholesterol levels, the study found those with better memory function had significantly higher LDL cholesterol levels.

Dr Katsumata concluded: "LDL cholesterol, especially large, buoyant LDL may be required to maintain or support memory function among older people."
