Does Lactic Acid affect the gastrointestinal system?

[Bikingmomof3]

Lara bars and Clif Nectar bars have no soy.

Clif Shot Bloks have no soy, and are like easy-to-swallow-and-chew gummi bears.

(no gluten, either! Regular Clif bars have oats in 'em, which make me sick sick sick)

Thank You! I am writing these down. I have not personally tried Lara or Clif Shot bloks, but I like The Nectar bars and so does my son. I will look for the other two. Thanks.
