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. Rainer J Klement from the University Hospital of Wurzburg reviewed the evidence of 162 scientific papers regarding the subject of carbohydrate restriction and cancer.

Dr. Klement found:
  • Cancer, which might be considered a disease of civilization, was very rare among uncivilized hunter-gatherer societies. Their diet was mainly meat and fat, whereas modern diets have quickly changed to easily digestible carbohydrates derived mainly from grains. Our genes have not had time to adapt to the new carbohydrate foods, and diseases of civilization have ensued.
  • Reducing the amount of dietary carbohydrates could stop, or at least delay, the emergence of cancer, and that growth of already existing cancer could be slowed down.
  • Most carbohydrates are converted into glucose by the body. Most cancer cells depend on glucose for growth as their ability to use fats or ketone bodies has been impaired.
  • High carbohydrate diets cause a rise in insulin and insulin like growth factor levels which promote cancer growth.
  • Ketone bodies that are elevated when insulin and blood glucose levels are low, have been found to stop cancer cells growing.

Dr. Klement concludes that the evidence presented in the review shows that reduction of the high carbohydrate intake in modern diets may play an important role in cancer prevention.
