Why Lupin?
One small bean. A remarkable nutritional profile. Here's the science behind why lupin is unlike anything else in your pantry.
Lupin vs. The Competition
Per 100g dry weight — lupin stacks up against the most popular protein and fibre sources.
| Nutrient | Lupin★ Best | Chickpeas | Lentils | Soy | Oats |
|---|---|---|---|---|---|
| Protein (g) | 40 | 19 | 26 | 36 | 17 |
| Dietary Fibre (g) | 30 | 17 | 11 | 9 | 10 |
| Net Carbs (g) | 2 | 45 | 40 | 20 | 56 |
| Glycaemic Index | ~15 | 28 | 32 | 15 | 55 |
| Fat (g) | 9 | 6 | 1 | 20 | 7 |
| Calories (kcal) | 371 | 364 | 352 | 446 | 389 |
More Protein Than Chicken
Lupin contains up to 40g of protein per 100g — more than chicken breast (31g), more than most legumes, and comparable to whey protein. Unlike many plant proteins, lupin contains all essential amino acids, making it a complete protein source. It's ideal for athletes, vegans, and anyone looking to increase their daily protein intake without relying on animal products.

3× More Fibre Than Oats
With over 30g of dietary fibre per 100g, lupin contains three times more fibre than oats and nearly double that of chickpeas. This fibre is predominantly prebiotic — meaning it selectively feeds beneficial gut bacteria like Bifidobacterium and Lactobacillus. Regular consumption supports a healthy microbiome, reduces bloating, improves bowel regularity, and may lower the risk of colorectal disease.

Stabilise Blood Sugar Naturally
Lupin has one of the lowest glycaemic index scores of any food — approximately 15. This means it causes minimal blood glucose spikes after eating, making it an exceptional ingredient for people managing type 2 diabetes or insulin resistance. Multiple clinical studies have shown that replacing high-GI foods with lupin significantly improves post-meal glucose and insulin responses.

Feed Your Gut Microbiome
Lupin's unique prebiotic fibre — primarily beta-glucans and oligosaccharides — acts as fuel for beneficial gut bacteria. Studies show that regular lupin consumption significantly increases populations of Bifidobacterium, which are associated with reduced inflammation, improved immunity, and better mental health. A healthy gut microbiome is increasingly linked to outcomes far beyond digestion — from mood to metabolic health.

The Low-Carb Flour Alternative
Lupin flour contains just 2g of net carbs per serve — compared to 70g+ in wheat flour. This makes it the ideal flour substitute for anyone following a low-carb, ketogenic, or diabetic-friendly diet. You can replace up to 30% of regular flour in most recipes with lupin flour to dramatically cut carbohydrates while adding protein and fibre — without sacrificing texture or taste.

Support a Healthy Heart
Clinical trials have shown that regular lupin consumption reduces LDL (bad) cholesterol and total cholesterol levels, while maintaining or improving HDL (good) cholesterol. Lupin's high arginine content supports healthy blood vessel function and blood pressure regulation. Its combination of fibre, protein, and bioactive compounds makes it one of the most heart-protective foods available.
