You literally can be healthy while eating zero sugar and zero carbs. Body needs a bit of glucose but it can make it from protein. And most definitely you don't need shove any fructose to your mouth, that's just useless poison causing fatty liver disease and other problems. The least problematic glucose you can eat is rice and such

Fruit in moderation is probably fine but definitely not juices or smoothies. That's just sugary water not much different from Coke
saying “zero” here is a fallacy since (like stated) you *will* get some carbs and sugar naturally from your food which our body needs to function properly, it sounds like you are confusing processed fructose with what occurs naturally in fruit (which also provide other nutrients & vitamins when eating the actual fruit itself vs just consuming the juice)

Fructose is fructose, safe in small doses, not required for survival.
