Nutrition Label Maths: Per 100g, Per Portion and Reference Intakes

Food labels are full of numbers – grams per 100g, per portion, kilocalories and percentages of reference intakes. This course teaches the maths to read them confidently: scaling from 100g to your portion, calculating percentages of reference intakes, comparing products fairly, and using the traffic-light thresholds.
