Gallocatechins are found in green tea, redcurrants, gooseberries, and marrowfatpeas. The consumption of these suggested reducing the risks of various cancers suchas those of the bladder, prostate, and oesophagus (Greenwell and Rahman 2015).Tea is one of the most popular beverages in the world, and most of the cultureswhose diets are rich in green tea have proportionately fewer cases of certain cancers(Sivakumar et al. 2010). Green tea (Camellia sinensis var. assamica) polyphenols,particularly the gallocatechins, are important antioxidants that offer chemopreventiveeffects against cancer (Takeo 2015). Another piece of research showed thatconsumption of green tea was closely related to a reduction in the risk of deaths dueto cancer (Jankun et al. 1997). Redcurrant (Ribes rubrum) in freeze-dried formshows preventive functions in terms of many cancer cell lines; this is expressedthrough cell cycle arrest and the interruption of gene expressions of cell divisionenzymes (Lim 2012). The potent inhibition of cancer cell lines such as stomach,prostate, intestine, and breast cancer cell lines offers promising anti-proliferativeprotection against cancer cell lines (Boivin et al. 2007).
