March 24, 2017 at 11:20 am #39504 BT NutritionistKeymaster Hi Christine, Greek yoghurt is listed under dairy products. A serve size for a meal would be 1/2 a cup whereas a serve size for a snack would be 1/4 of a cup. Kindest Regards, BT Nutritionist 🙂 Author Posts You must be logged in to reply to this topic.
