The second area of content is the science of nutrients: what each nutrient does for the body, where it is found, and what happens if you get too little or too much. It splits into macronutrients (needed in large amounts) and micronutrients (needed in small amounts). This page maps the area and links to a focused answer page for each nutrient.

The macronutrients

Protein
Needed for growth, repair and making enzymes, hormones and antibodies; built from amino acids, with the high and low biological value distinction and protein complementation. See Protein.
Fats and oils
The most concentrated source of energy, carrying fat-soluble vitamins and providing essential fatty acids, with the saturated versus unsaturated distinction and cholesterol. See Fats and oils.
Carbohydrates
The body's main source of energy, split into simple sugars and complex starch, plus free sugars and dietary fibre. See Carbohydrates.

The micronutrients and water

Vitamins. Fat-soluble vitamins A, D, E and K and water-soluble B group and C vitamins, their functions, sources and deficiency effects, and how cooking affects them. See Vitamins.

Minerals and water. Calcium, iron and sodium, their functions and sources, and the importance of water and hydration. See Minerals and water.

How this area is examined

Principles of nutrition is assessed in Component 1, the written exam worth 50% of the GCSE, and is applied in Component 2 when you analyse dishes. Expect questions that link a nutrient to its function, name sources, explain deficiency or excess, and apply nutrition to a named person or meal.

How to study this area

Principles of nutrition rewards precise, structured learning.

  1. Learn each nutrient as a set. Function, sources, and the effects of too little and too much.
  2. Master the key distinctions. HBV versus LBV protein, saturated versus unsaturated fat, simple versus complex carbohydrate.
  3. Know the headline micronutrients. Vitamin C, vitamin D, calcium, iron and sodium, with their deficiency conditions.
  4. Link nutrients to foods. Connect each nutrient back to the commodities in Area 1.
  5. Practise applying nutrition. The exam sets nutrition in the context of real people and meals, so rehearse that style.
