I ate cheese every day for most of my childhood all through my early adult years. It was quite literally my favoriye food. Snack, meals, I had it all day long.
During a 2-year period, I started getting sicker and sicker to the point where I was missing work on a regular basis. Cut dairy out of my diet, and now I have no issues.
Lactose intolerance crept up on me like an assassin.
