40 products · prices last checked 22 October 2026Built by an Accredited Practising Dietitian How it works
- Dry lentils and tinned legumes are the cheapest per gram of protein, but come with more calories than lean meat or fish.
- Tinned tuna and plain high-protein yoghurt give a good balance of low cost and low calories.
- 30 g is a comparison unit, not a recommendation. Protein needs vary from person to person.
