It is sometimes hard (or impossible) to completely remove sugar, as some items contain natural sugars e.g. even natural yogurt without added sugar contains sugar from sucrose. There was a diet that gained popularity in my country that was the "5% sugar" diet. Here on the labels of items there is always the per 100g reference, so if the sugar is <=5 on that column, you're good to go. So it's easy to stick to and it's interesting what gets filtered from eating in this way.
