Macro partitioning
Moderate dietary fructose consumption (≤50g/day or ~10% of energy) does not have deleterious effects on lipid and glucose control, and consumption up to 100g/day does not influence body weight.
You do not need to fear moderate amounts of fructose (up to 50g/day, or about 10% of your calories). It does not inherently cause weight gain or metabolic issues at this level. The problem arises from excessive consumption and overall caloric surplus, not the fructose itself. Focus on total energy balance rather than demonizing specific sugars.
It has been considered that moderate fructose consumption of ≤50g/day or ~10% of energy has no deleterious effect on lipid and glucose control and of ≤100g/day does not influence body weight.
Why this rating
Based on a comprehensive review of epidemiological, acute, and chronic human studies, though the author notes limitations in some specific trials.
