SugarAssignment.com is a reference site about sugar: the chemistry, the metabolism, the food science, and what the published research does and doesn’t establish about health effects.

Who writes this

One person, not a medical organisation. I am not a physician, a dietitian, or a research scientist, and nothing here is written or reviewed by one. If you see a claim on this site that matters to a decision you’re making about your health, check it against the primary source or ask someone qualified.

I mention this plainly because the alternative — a vague “our editorial team” or an invented medical reviewer — is how a lot of health content on the web pretends to an authority it doesn’t have.

Where the information comes from

Pages cite named studies with their journal and year wherever a specific claim depends on one. Where the evidence is weak, contested, or observational, the pages say so rather than rounding it up into a stronger claim. Sugar is a topic where overstatement is the norm in both directions, and the aim here is to report what the studies actually measured.

Numbers for foods and products come from manufacturer nutrition labels and USDA FoodData Central. Chemistry and metabolic pathways come from standard biochemistry references.

Corrections

Some of the citations on this site have been wrong. In August 2026 I audited the referenced studies and found several that were misattributed — a prospective cohort described as a randomised trial, a review described as a primary study, effect sizes reported in the wrong units, and two citations that could not be verified against any source and were removed. Those are corrected, and the process is ongoing for the remainder of the corpus.

If you find an error, please report it and I will fix it. That offer is genuine, and the correction history above is the evidence that it is.

What this site is not

It is not medical advice, and it is not a substitute for talking to a clinician. It does not diagnose anything or recommend a treatment. If you are managing diabetes, pregnancy, kidney disease, or any other condition where sugar intake matters clinically, your care team’s guidance supersedes anything written here.
