✦ Synopsis

Zhang et al. 1 found an inverse association between intake of fresh or dried mushrooms and breast cancer in both premenopausal and postmenopausal Chinese women.

Several phytochemicals could be implicated in the reduction of breast cancer risk by mushrooms. One that deserves consideration is vitamin D2. It is known that mushrooms are naturally rich in ergosterol, generating vitamin D2, when exposed to ultraviolet light B (UVB), even postharvest. 2 This ergocalciferol is bioavailable and also increases the serum 25(OH) vitamin D2 levels 3 in humans.

A protective effect of vitamin D in breast cancer risk was observed in some studies. Intensity of UVB irradiance, higher serum vitamin D levels and higher intake of vitamin D have been associated with decreased risk of breast cancer in women. [4][5][6] It would be interesting to know the content of ergocalciferol in the mushrooms ingested by the women in Zhang's study, as well as their serum 25(OH)vitamin D2 levels.

1,25-(OH) 2 D 3 (1,25) and 24,25-(OH) 2 D 3 (24,25) mediate their effects on chondrocytes through the classic vitamin D receptor (VDR) as well as through rapid membrane-mediated mechanisms, which result in both nongenomic and genomic effects. In intact cells, it is difficult to distinguish between g
