- 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/day6.30g6.30g13%
- 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/day29.4g29.4g42%
- Carbohydrate 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/day1.40g1.40g1%
- 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/day1.50g1.50g5%
