Hi Welcome to the healthcare magic and thanks for asking your query here Yes if you consume lots of dairy product you may get diarrhea and abdominal pain specially if they are contaminated or not properly stored However Green color of stool may be due to diarrhea as Food may be moving through the large intestine too quickly, due to diarrhea. As a result, bile doesn t have time to break down completely leading to green stool Also Green leafy vegetables, green food coloring can also cause green stool As your diarrhea will improve color of stool will also improve If you don t get any improvement within 24 hours than i would strongly suggest you to visit your doctor to further evaluate the condition as diarrhea and abdominal pain may be related to many other medical conditions including gastroenteritis , Irritable Bowel Syndrome etc and you should get it checked with your doctor before taking any medicine I Hope it helps Thanks and get well soon
