Tofu is a 2015 British online documentary series created by Russell T Davies and presented by journalist and YouTube host Benjamin Cook, available on All 4, Channel 4's video-on-demand service. The sister series to Channel 4's Cucumber and E4's Banana, Tofu is a documentary series that focuses on a range of sex attitudes in the twenty-first century from the viewpoint of everyday people. Like Cucumber and Banana, the name of the series refers to the same urological scale of hardness of the male erection which starts at tofu, goes through peeled banana and ends at cucumber from a European study that inspired Davies.
