Both approaches entirely missing the diet and lifestyle connection and just scare people into restrictive and orthorexic diets and behavior.
Honey?
Jokes aside, there are a few natural sugar sources without fiber, like sugar cane (it has fiber, but we just spit it). I think we can all agree that eating too much honey or sugar cane juice would be bad for our health.
There's also sugars like inulin (https://en.wikipedia.org/wiki/Inulin), which are actually classified as soluble fiber because we can't digest them, so the bacteria in our digestive system does it for us. Inulin is a prebiotic, so it's actually healthy to eat in moderation.
