The quantitative nutrient-cluster definition of hyper-palatable foods, and how much of the US food supply meets it.
What the evidence says
- Three quantitative clusters define hyper-palatable foods: fat+sodium (>25% kcal fat, ≥0.30% sodium), fat+sugar (>20% kcal each), carbs+sodium (>40% kcal carbs, ≥0.20% sodium)[1]
- The paper measures composition, not eating. Its account of why these combinations matter is background, and hedged: ”preliminary research suggests that foods may be designed in ways that create hyper-palatability”, and combined ingredients ”may facilitate overconsumption despite satiety”[1]
- 62% of the 7,757 foods in the USDA FNDDS met hyper-palatable criteria; the authors conclude that ”a substantial percentage of foods in the US food system may be hyper-palatable”. The FNDDS is a database of foods, not weighted by sales[1]
- Fat+sodium is the most common cluster — 70% of HPF items (3,351/4,795) — then fat+sugar 25% (1,176/4,795), then carbs+sodium 16% (747/4,795). The clusters are largely distinct: fewer than 10% of HPF items meet more than one[1]
- 49% of items labeled “reduced or no” fat, sugar, salt or calorie still qualify as hyper-palatable (216/443) — and for the reduced-fat or reduced-calorie subset specifically it is 80% (102/127). Those items are only 5% of all HPF identified (216/4,795), so it is a real labelling gap and a small share of the problem[1]
- Hyper-palatable is not a synonym for calorie-dense: 49% of HPF items had low energy density (< 2 kcal/g), and the range runs from under 1.0 kcal/g to 8.4 kcal/g[1]
- What the paper found about unprocessed foods is narrower: ”The HPF criteria did not capture any fresh or raw fruits, meats, or fish”, and on that it says ”Initial evidence supports the HPF criteria as appropriately distinguishing HPF from foods that are naturally occurring and minimally processed”[1]
- Hyperpalatable foods drive “conditioned hypereating” — repeated exposure creates dopamine-mediated compulsive eating triggered by food cues (sight, smell, thought of food) before eating even begins[2]
