Pronto is offering three iced lattes regular, matcha and cocoa. All are said to have 25 to 50 times the amount of probiotic culture of a regular yogurt. That is from the small print which is very difficult to read. I am not at all sure what they use as a baseline, what type of lactic acid bacteria it is or if it is alive or not. I somehow doubt that many lactic acid bacteria could survive the steaming process to make genuine latte.
In any case, this product makes the popular link between beauty (based on measures of skin health) and lactic acid bacteria. プロント
