- Protein ProteinBuilds and repairs tissue, drives enzymes and hormones. Made up of amino acids — nine of which the body can't make itself.UK adult RI: 50 G/day1.60G1.60G3%
- Fat FatAll fats combined: saturated, monounsaturated, polyunsaturated, and trans. Carries fat-soluble vitamins (A, D, E, K) and contributes 9 kcal per gram.UK adult RI: 70 G/day0.20G0.20G0%
- Total carbohydrate Total carbohydrateAll carbohydrate combined: sugars, starches, and fiber. Calculated by subtracting water + protein + fat + ash from the food's total mass — hence "by difference".UK adult RI: 260 G/day29.3G29.3G11%
- Fiber FiberPlant carbohydrate the body can't digest. Feeds gut bacteria, slows sugar absorption, and supports regular digestion. UK adults: target 30 g/day.UK adult RI: 30 G/day1.40G1.40G5%
