Kris Moore-- First of all, I am not a doctor. However, when my doctor thought I might have LI, he said drink a glass of milk on an empty stomach. I had a very time day for the rest of the day. From then on, I drank 99% lactose free milk and chewed Lactaid tablets. My problems continued. I continued to report problems including experiencing 4 sinus infections per year and increasing frequency and lengthier periods of malaise. I eventually suggested to him that it had to be either dairy or sinuses. He sent me to a specialist who said my sinuses were totally clear. I then stopped all dairy (2 years ago this month). I have felt much better since then. I've had only one sinus infection in 2 years and that came with a deadly summer cold. As far as dairy is concerned, I get ambushed from time to time but generally do OK. My main points are these: doctors cannot determine what affects each and every person because we are all so different. Secondly, we know our bodies better than doctors. Thirdly, taking certain non-threatening steps is in your best interest. Therefore, I recommend that your friend's daughter stop using dairy for a few weeks. It won't cause any harm and poses no risk. As far as non-dairy foods, there are many alternatives available, and people on this list can help out. Don >Any suggestions? I have suggested that she stop dairy entirely, but the mom >is really reluctant to do this because she says her daughter is "a very picky >eater
