Chemical-induced cancer protection against

There are no reported feeding studies showing protection by broccoli against chemically induced cancers in animal models. However, there is an abundant... 

In some experimental studies, L-tryptophan has been observed to have a protective or inhibitory effect against chemically induced cancers. A possible explanation appears to rely on the ability of tryptophan or its metabolite to enhance the activities of many enzymes, some of which are...

Correlations exist between manganese toxicity and exposure to other toxic substances in the environment, such as ozone [540-542] against which the element offers some protection against radical oxidative damage, or susceptibility to chemically induced cancer [543], cadmium [544,545], other trace elements [546], and alcohol [547]. Lysosomes in the brain have been found to play a role in manganese toxicity [548], and mechanisms for pulmonary clearance of soluble and insoluble forms of the element manganese have been discussed by Drown et al. [549].

Dietary fiber has been suggested to play a protective role against chemically-induced toxicity (1) and against colon cancer (2). However, the mechanism(s) by which dietary fiber modulates chemical toxicity or colon cancer has not been well studied. The fiber fraction of the diet is resistant to mammalian digestive enzymes and consequently dietary fiber is not absorbed from the small intestine (3). However, certain types of dietary fiber specifically fermentable fibers, including the pectic substances and hemicelluloses, are readily digested by the intestinal microflora (4,5). Pectic... 

Both p-carotene and vitamin A can inhibit growth in a large range of human cancer cell lines (Krinsky, 1993 Niles, 2000). Several animal studies have shown that vitamin A deficiency promotes the development of spontaneous and chemically-induced tumors, whereas dietary supplementation with vitamin A can prevent chemically-induced tumor development (Niles, 2000). Likewise, p-carotene protects against tumor development in animal models (Krinsky, 1993 Cooper, 2004 Russell, 2004). Nevertheless, P-carotene is preferred for human studies because blood and tissue levels increase in proportion to dietary intake, whereas vitamin A level does not increase in a linear manner because of homeostatic regulation high levels of vitamin A are toxic (Cooper, 2004).
