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.

Dr Elizabeth Berry-Kravis notes that Fragile X syndrome (FXS) is associated with intellectual disability and behavioural dysfunction, including anxiety, ADHD symptoms, and autistic features.

Dr Berry-Kravis found that during the course of follow up of patients with FXS she noted that many patients had low cholesterol levels and low levels of high density lipoprotein (HDL) cholesterol.

She then initiated a systematic review of all cholesterol values present in charts from over 500 patients with FXS and revealed that total cholesterol, low density lipoprotein (LDL) cholesterol and HDL cholesterol were all significantly reduced in males with FXS compared with normal levels.

Dr Berry-Kravis findings reveal that low cholesterol levels are associated with Fragile X syndrome.
