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.

The study investigated the association between vitamins B12 and B6 with breast cancer. The dietary habits of 712 women with breast cancer were compared with 712 women without breast cancer.

The study found:
  • Women with the highest vitamin B12 had 64% less breast cancer than women with the lowest vitamin B12.
  • Women with the highest vitamin B6 had 30% less breast cancer than women with the lowest vitamin B6.

The best dietary sources of vitamin B12 are liver, turkey, fish, beef, lamb and eggs.

Excellent dietary sources of vitamin B6 are liver, eggs, turkey, pork and fish.
