Specific nutrient requirements for all product categories according to PNC nutrient density classification.

Category Reference quantity Nutrients to limit Criteria for nutrients to limita Stepwise class levels Food groups and/or NTEs (and notes)
Class IV Class III Class II Class I
Refreshment beverages 355 ml (12 fl oz) Calories (kcal) 40 NA
Calorie limit meets the definition of low-calorie drinks in most markets
Saturated fat NA
iTFA (g/100 g) ≤ 0.1
Added sugars (g/100 ml) ≤ 3 ~7 ≤ 5 ≤ 3 0
Sodium (mg/kcal) ≤ 1.0
Savory or sweet snacks 30 g: Savory snack, nut bars, cookies, nut clusters
40 g: Grain-based or fruit- based bars
80 g: Cakes and muffins
Calories (kcal) ≤ 200 ≥1 Food group
Snacks considered at 10% of daily calories = 200 kcal. Upper limit of saturated fat intake at 10% total dietary energy.
For snacks 10% energy from saturated fat = 1.1 g per 100 kcal

Nuts, seeds, nut butters 30 g Calories (kcal) ≤ 200 NA Nuts and seeds are considered a plant-based protein source thus is intrinsic in the category
Calorie cap of 200 kcal meets recommended levels and limits amount of fat and saturated fat that occur naturally in these foods
Saturated fat (g/100 kcal) Prefer nuts/seeds w/ low-saturated fat ≤ 1.7 ≤ 1.4 ≤ 1.1 ≤ 0.8

Dairy and convergence beverages 240 ml Calories NA NA NA NA NA Dairy: FGE should be dairy; NTE should be calcium and 20% of ref amount of calcium
Convergence: ≥ 2 FGEs, can be a combination with ≥12 FGE each Food groups vary by Class level*
Calories are limited by the amount of added sugar and fat. Sweetness will come from 100% juices where possible
