This is in response to the request by Karen Foard, but I felt others
might like the answer in case it hasn't been mentioned.
The article is the the December 1997 issue of "Medicine and Science in
Sports and Exercise" (vol. 29, #12).
The title is "Effect of Exercise on Milk Immunoglobulin A".
The authors are Richard Gregory, Janet Wallace, and Barry King.
I couldn't find a local source for it, so am having it sent to me from
our provincial nurses' association.
