Lactic acid in foods/bev

[Ivanko]

I was looking at some diet soda and noticed the second from last ingredient was "lactic acid". I looked it up and apparently lactic acid is in a lot of foods, including casein/milk/cotage cheese.

Does ingesting lactic acid in food cause the same effects as lactic acid produced from exercise?
