Best Protein Sources: Quality, Not Just Quantity
When it comes to protein, how much you eat matters — but so does what kind. Protein quality varies, and understanding the difference helps you get more from every gram. Here's a clear guide to the best protein sources and how to choose them.
Complete vs Incomplete Proteins
Protein is made of amino acids, nine of which are "essential" — your body can't make them, so they must come from food.
- Complete proteins contain all nine essential amino acids in good amounts. Mostly animal sources
- Incomplete proteins are missing or low in one or more. Mostly plant sources — but combining different plants covers the gaps
The Best Animal Protein Sources
These are complete and highly "bioavailable" (easily used by your body):
- Chicken and lean poultry — high protein, low fat
- Lean beef — protein plus iron, zinc and B12
- Fish and seafood — protein plus, in oily fish, omega-3s
- Eggs — often considered a "gold standard" for protein quality
- Dairy — Greek yoghurt, cottage cheese, milk; whey and casein are dairy-derived
The Best Plant Protein Sources
Excellent in a varied diet:
- Soy (tofu, tempeh, edamame) — one of the few complete plant proteins
- Legumes — lentils, chickpeas, beans
- Quinoa — a complete plant protein
- Nuts and seeds — protein plus healthy fats
The key with plant proteins is variety — eating a range across the day covers the full amino acid profile.
What "Quality" Means in Practice
For most goals, prioritising complete, whole-food proteins at each meal is the simplest winning strategy. That's exactly how we build our meals — around quality whole-food proteins like chicken and beef, delivering 30g+ of high-quality protein per serve.
Frequently Asked Questions
Is animal protein better than plant protein?
Animal proteins are complete and highly bioavailable. Plant proteins work well too, especially when varied to cover all amino acids.
What's the highest-quality protein?
Eggs, dairy, lean meats and fish rank highly for both completeness and bioavailability.
Can vegetarians get enough quality protein?
Yes — by combining sources (e.g. legumes plus grains) and including soy and dairy or eggs if eaten.
What proteins do your meals use?
Quality whole-food proteins, prepared fresh — chicken, beef and more.
