Now we have fat-blocking soda. The “science” to this claim is that a non-digestible starch called dextrin, which is classified as fiber is added to regular Pepsi. Dietary fiber does help to absorb dietary fat, so technically, this is true. Despite the flimsy connection, this kind claim is not illegal in Japan.
The Japanese approval process is lenient for these kinds of fortified foods, and this soda certainly won’t harm anyone — it’s safe. But don’t expect this on US shelves anytime soon. The FDA regulates foods and beverages and monitors health claims made by these products. The FDA prevents soda and candy from being fortified with nutrients. (Fiber is a nutrient).
The bottom line is, as you well know — when it sounds too good to be true, it probably is.
