I've been eating a large tub of plain unflavoured yogurt every day for the last 25 years. It's one of my diet staples. I usually mix it with oats or blueberries or just eat it by itself...Plain unsweetened unflavored yogurt is the best and most healthy...The biggest problem with yogurt is that many brands have added sugars, artificial sweeteners and all types of other unnecessary ingredients. Why do food companies add sugar or artificial sweetener, colourings and flavours to a fruit yogurt which already has naturally occurring sugars in it ??...Think about it, fruit already has sugar and is sweet, dairy has sugar in it and food companies dumping more sugar on top of sugar, or worse they put some chemical sweetener and flavour into it and corrupt a perfect food.
