Scientific research on nutrition and natural approaches and resources in cancer. Studieabstracten study and analysis.
Here we list articles and studies or research on cancer in relation to nutrition. With some additional comments other as we found on the Internet. We will complement these articles regularly, but that takes time and we want very carefully. We have tried to research and articles in logical and more or less alphabetical order. Often an article in the name of nutrient - vitamin etc. But sometimes in diets or diet in cancer or cancer type out the first named, including bladder cancer and vitamins in the BA. So take the name of one nutrient or use search to start because of various cancers are also often important studies and articles that are not all in this list.
If there are people who can give us tips like please send us remarkable investigations and we post on the site. (See also reading list ( This list compiled by physician-biologist Erik Valstar has exceeded 1500 and are all randomized trials) and cancer rates ). In addition, a recommendation to information on proven effects of diet and nutritional supplementation in cancer of the book: Nutritional intervention in cancer, a signal to the conventional oncology. Because physician-biologist Dr Engelbert Valstar. The book costs 16.95 and the ISBN number is 90 5860 192 7.
Chlorophyll from spinach offsets carcinogenic effect of heme, a lot of fabric and especially common in red meat
March 8, 2005: Source: Carcinogenesis. 2005 Feb; 26 (2) :387-93. Epub 2004 in November 1918. Dutch researchers from Wageningen prove again that animal haem iron and organic = common in red meat - colon cancer causes. In this new study, they demonstrate that spinach chlorophyll and more specifically to the substance's carcinogenic effect on heme can lift. However, there is an objection to the quantities of spinach or other green leafy vegetables daily would be needed to eliminate this carcinogenic effect. A man was one pound per day to eat spinach to the carcinogenic effect of heme from an everyday piece of red meat, pork or beef, to compensate. Therefore, it seems easier to just not eat red meat any more. Chicken is not suspicious and fish is even good as prevention of cancer. In the Algemeen Dagblad on Tuesday, March 8 is an article about this study and below the abstract of the study.Green vegetables, red meat and colon cancer: chlorophyll Prevents the cytotoxic and hyperproliferative effects of haem in rat colon.

Diets high in red meat and low in green vegetables are associated with Increased risk of colon cancer. This association Might Be Partly due to the heme content of red meat. In rats, dietary haem is metabolized in the gut to a cytotoxic That factor increases colonic cytotoxicity and epithelial proliferation. Green vegetables containerization chlorophyll, a magnesium porphyrin structurally analogous to haem. We studied whethere green vegetables inhibit the unfavourable colonic effects of haem. First, Were rats fed a purified control diet or purified diets supplemented with 0.5 mmol haem / kg, spinach (chlorophyll concentration 1.2 mmol / kg) or haem plus spinach (n = 8/group) for 14 days. In a second experiment, we studied a group That Also Received haem plus purified chlorophyll (1.2 mmol / kg). Cytotoxicity of faecal water was Determined with a bioassay and colonic epithelial cell proliferation was Quantified in vivo by [methyl-(3) H] thymidine incorporation Writing newly synthesized DNA. Exfoliation of the colonocytes was as Measured Amount of rat DNA in feces. Both studies in heme Increased cytotoxicity of the colonic contents approximately 8-fold and proliferation of the colonocytes "almost 2-fold. Spinach or an equimolar Amount of chlorophyll supplement in the haem diet inhibited heme synthesis effects Completely. Clearly haem inhibited exfoliation of colonocytes, an effect counteracted by spinach and chlorophyll. Finally, size exclusion chromatography showed That chlorophyll prevented formation of the cytotoxic haem metabolite. We concluded green vegetables That May Decrease Colon Cancer Risk becauses chlorophyll Prevents the detrimental, cytotoxic and hyperproliferative colonic effects of dietary heme.
