Oh yeah. Try an elimination diet that zeroes out sugar and you’ll see how hard it is to find anything on grocery stores that doesn’t have an added sweetener.
Yogurt, bacon, sauces are all sweetened (outside of high end speciality brands). Eggs, raw meat, and raw vegetables are basically the only way to avoid sugar.
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.
