Cut Back on Added Sugar

Trim added sugars from foods and especially drinks, without chasing a zero-sugar ideal.

Evidence suggests…

Evidence suggests reducing added sugars, especially sugary drinks, is a sensible target, though formal sugar guidelines rest on relatively low-quality evidence. We grade this B: cutting liquid sugar is well justified, while strict thresholds are not firmly established.

How to do it

Cut one source of added sugar per week, starting with sugary drinks

This is the evidence-based dose. A shorter session still counts, it just gives partial benefit rather than the full effect.

Common misconceptions

'Sugar is a toxic, addictive drug.' Overstated; the issue is excess, not poison.
'Natural sugars like honey are health foods.' Still added sugars with modest effects.
'You must quit sugar entirely.' Moderation beats all-or-nothing.

What we won't claim

Do not claim any food, diet, or supplement cures, treats, or prevents any disease

When to seek a professional

Signs of disordered eating (food/weight preoccupation, restriction, bingeing, purging, compulsive exercise) -> qualified eating-disorder professional
Diagnosed medical condition (diabetes, chronic kidney disease, heart failure, GI disease) -> registered dietitian or physician
Pregnancy or breastfeeding -> prenatal provider or registered dietitian
Unintentional weight loss, difficulty swallowing, or persistent GI symptoms -> medical evaluation
