Here’s a detailed list of the best high-protein foods at Aldi UK, based on value, convenience, and protein per 100g. I’ve added measured values (from UK food labels) where possible. All items are regularly stocked in Aldi stores as of 2025.
🥩 Meat & Fish

✅ Bonus Tips to Shop Smarter at Aldi
- Look for “Protein Kick” labels — Aldi often uses this branding on yoghurts and ready meals.
- Compare per 100g, not just per serving — especially on yoghurts and bars.
- Go frozen when you can — especially chicken and fish, it’s often cheaper and lasts longer.
