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. Jennifer Lin, an Assistant Professor of Medicine at the Harvard Medical School, examined the association of intakes of different types of fat with the risk of colon cancer. She and her colleagues analyzed the diets of 37,547 women over 8.7 years.

Dr. Lin found:

  • Women who consumed the most saturated fat had an 8% reduced incidence of colon cancer compared to the women who ate the least.
  • Women who consumed the most cholesterol had a 21% reduced incidence of colon cancer compared to the women who ate the least.
  • Women who consumed the most red meat had a 34% reduced incidence of colon cancer compared to the women who ate the least.
  • Women who consumed the most vegetable fat had a 21% increased incidence of colon cancer compared to the women who ate the least.

This study shows that dietary cholesterol, animal fats and red meat give protection from colon cancer, whereas vegetable fats (margarine, sunflower oil etc.) increase the risk of colon cancer.
