Derrick Lonsdale M.D., Fellow of the American College
of Nutrition (FACN), Fellow of the American College for Advancement in Medicine (FACAM) is a pediatrician and researcher into the benefits of certain nutrients in preventing disease and psychotic behavior. Thiamine is a special vitamin because as the cause of beriberi it is one of only four vitamins associated with a named pandemic deficiency disease. Of these four vitamins, only thiamine requires transport proteins to diffuse throughout the body. A thiamine derivative called TTFD is a thiamine precursor that does not require transport proteins to freely diffuse.

Child violence
In 2002 Lonsdale caused controversy when he linked child violence (children killing other children) to dietary deficiencies rather than the accepted social causes. Lonsdale put this down to 'high calorie malnutrition' where children overeat high calories foods that lack vital nutrients resulting in an upset to 'brain balance'. He pointed the finger at a range of 'normal' foods as well as generally accepted junk foods.Books
Lonsdale has written several books, including:- A Nutritionist's Guide to the Clinical use of Vitamin B-1.
