Guest guest Posted September 11, 2005 Report Share Posted September 11, 2005 This has many interesting data in it. Yes and I wonder why there may be a relationship between low BMI and cancer as suggested by:" In men, a U-shaped association between body mass index (BMI) and cancer occurrence was observed, suggesting a very low rather than high BMI has an impact on the total cancer risk in populations with a low average BMI"Tom Quote Link to comment Share on other sites More sharing options...

Guest guest Posted September 12, 2005 Report Share Posted September 12, 2005 Hi Tom: Yes. Here are a couple of possibilities. First, people with cancer lose weight. I don't know how long it takes for cancer to generate symptoms noticeable enough for the patient to visit the doctor, nor whether a patient with sub-clinical cancer starts to lose weight for quite some time before symptoms become evident. Only an oncologist could answer this question I think. (IOW the low BMI might be caused by the cancer, possibly, rather than the other way around.) Second, healthy slim people eat less than higher BMI individuals. Perhaps as well as consuming fewer calories many slim people (hopefully not us who track our nutrient intakes) are also not getting enough of the important cancer-protective nutrients. If low BMI, healthy people who are eating healthy foods and are getting the full RDAs for micronutrients are more susceptible to cancer in some way because of their low BMI, then it is something we would REALLY need to take a close look at. Certainly we know for sure that properly fed low BMI mice get 75% less cancer up to the human equivalent age of 100 years.
