Nutrients, balanced diets and health claims
≈ 48 minNutrients, balanced diets and health claims
A balanced diet supplies carbohydrates, proteins, fats, vitamins, minerals, fibre and water in amounts appropriate to a person's needs. Nutrients have distinct roles: carbohydrates and fats provide energy; proteins provide amino acids for growth and repair; vitamins and minerals support specific functions. A nutrition claim should be evaluated with serving size, evidence, individual needs and possible trade-offs rather than a single slogan such as 'fat is bad'.
