Kanker risico’s voor bekende voedingsmiddelen

Men verwacht niet dat gewone, alledaagse voedingsmiddelen giftige stoffen bevatten. Als we de toxiciteit ten opzichte van kraanwater bepalen ziet dat er anders uit en blijken hoge RR-waarden voor te komen!

Note: The items listed above are for illustrative purposes only, and are not intended as a guide for safe behavior. Relative risk is based on experiments subjecting rodents to very high dosages. The risk of these items to humans, in the quantities given above, is thought to be trivial. Source: Bruce N. Ames, Renae Magaw, Lois Swirsky Gold, “Ranking Possible Carcinogenic Hazards,” Science, Vol. 236, April 17, 1987, pp. 271-236.

1 The underlying measure of risk used here is a HERP value: Human Exposure dose divided by Rodent Potency dose. The measure of rodent potency is the milligrams of substance per kilogram of rodent body weight necessary to produce cancer in one-half the rodents, given daily exposure over the rodents’ lifetime. Human exposure is measured by the daily consumption indicated in the table per kilogram of human body weight. In the table above, the HERP values have been normalized with respect to the HERP value for water. A value of 100,000 means that the human exposure dose per kilogram of weight is exactly equal to the amount of the substance per kilogram of weight necessary to produce cancer in one-half of the rodents.

  • I've alllllllways said that asking smokers "do you want to quit?" and reporting the results of that question, as is, is horribly misleading. It's a TWO part question. After asking if one wants to quit it must be followed up with "Why?" Ask why and the majority of the answers will be "because I'm supposed to" (victims of guilt and propaganda), not "because I want to."
