Macronutrients
Tremoços are exceptionally nutrient‑dense. Dried lupin seeds contain about 30–40 % protein and roughly 30–37 g of dietary fibre per 100 g. This means that nearly half of the bean’s dry weight is protein, making it one of the richest plant‑based protein sources available. Lupin flour maintains a similar profile with about 40 % protein and 37 g fibre per 100 g. Even more concentrated, lupin protein isolates made by alkaline extraction can contain more than 70 % protein.
Most of the carbohydrates in tremoços are non‑digestible fibre, leaving virtually zero net carbs. The beans are low in fat and contain primarily unsaturated fatty acids.
Vitamins, Minerals & Phytochemicals
In addition to protein and fibre, tremoços provide significant amounts of B‑group vitamins, particularly folate and thiamine, as well as minerals like calcium, iron, magnesium, phosphorus, potassium and manganese. They also contain antioxidants and phytochemicals such as polyphenols and carotenoids that may offer additional health benefits.
Health Benefits
- Satiety & Weight Management: The combination of protein and fibre promotes fullness and may help with weight control.
- Cardiometabolic Health: Consuming whole lupin beans can improve glycaemic control and lower blood pressure, helping reduce cardiovascular and metabolic risks.
- Gut Health: Prebiotic fibres support a diverse and healthy gut microbiota, improving digestion and nutrient absorption.
- Gluten‑Free & Plant‑Based: Tremoços are naturally gluten‑free and suitable for vegan and vegetarian diets, offering a complete amino acid profile when combined with grains.
- Low Glycaemic Index: With almost no digestible carbohydrates, tremoços have a minimal impact on blood sugar, making them ideal for low‑carb and ketogenic diets.
Caution: Tremoços are related to peanuts and soybeans. Individuals with legume allergies should exercise caution. Raw lupin seeds contain bitter alkaloids and must be properly soaked and cooked before consuming.
