Lablab Bean: Top Health Benefits, Nutrition and Cooking Guide .

Imagine a single food that provides complete plant-based protein, strengthens your immune system, stabilises blood sugar, and can grow in drought conditions where most crops fail. That food exists — and chances are, you have not heard enough about it.

Lablab Bean, scientifically known as Dolichos lablab or Lablab purpureus, has been a dietary staple in Bangladesh, India, and across sub-Saharan Africa for thousands of years. Known locally as shim in Bangladesh and val in India, this versatile legume goes by many names — Hyacinth Bean, Indian Bean, Egyptian Bean, and Bonavist Bean. Despite its long history and remarkable nutritional profile, lablab bean remains largely unknown in Western nutrition circles.

That is changing rapidly. Food scientists, agronomists, and nutritionists around the world are now recognising lablab bean as one of the most promising crops for the future — a climate-resilient superfood that can help address both personal health goals and global food security. If you are already exploring our Future Superfoods Collection, you will know that the next generation of powerhouse foods often comes from rediscovering ancient crops. Lablab bean is a perfect example.

In this comprehensive guide, we cover everything you need to know: its full nutritional profile, evidence-backed health benefits, how to cook it, and why researchers are betting on it to feed the future.

What Is Lablab Bean? A Quick Overview

Lablab bean is a tropical legume belonging to the Fabaceae family. Specifically, it is a fast-growing, climbing vine that produces pods containing flat, oval seeds in shades of white, cream, brown, or purple, depending on the variety. Importantly, both the young pods and the mature dried seeds are edible and widely used in cooking.

The plant is extraordinarily adaptable. For instance, it can grow in poor soils with minimal rainfall, fix atmospheric nitrogen (which improves soil fertility), and tolerate heat that would destroy other crops. As a result, these qualities make it especially valuable in tropical and semi-tropical regions of Asia, Africa, and South America.

In Bangladesh, lablab bean (shim) is a winter vegetable enjoyed in curries, stir-fries, and dals. Similarly, in India, it is a common ingredient in coastal cuisines. In addition, in East Africa, it has been a reliable protein source for rural communities for generations. However, despite this widespread traditional use, modern nutrition science is only beginning to fully document its health potential.

Complete Nutritional Profile of Lablab Bean

One of the most impressive things about lablab bean is the sheer density of nutrients it packs per serving. To give you an accurate picture, here are the values for both raw dried beans and cooked beans separately — an important distinction that is often overlooked.

Nutritional Values of Raw Dried Lablab Bean (per 100g)

Nutrient	Amount
Protein	25–28 g
Dietary Fiber	20–22 g
Carbohydrates	55–60 g
Total Fat	1.5–2 g
Calcium	100–120 mg
Iron	6–7 mg
Folate (Vitamin B9)	350–400 mcg
Vitamin A	15–20 mcg RAE
Vitamin C	5–8 mg
Phosphorus	350–400 mg
Potassium	1,200–1,400 mg

Nutritional Values of Cooked Lablab Bean (per 100g)

Nutrient	Amount
Protein	8–10 g
Dietary Fiber	5–7 g
Carbohydrates	20–25 g
Iron	2–3 mg
Calcium	35–45 mg
Calories	115–130 kcal

Note: Nutrient values drop after cooking due to water absorption and heat. However, cooking also removes anti-nutritional compounds like phytates and lectins, making the remaining nutrients far more bioavailable. Always eat cooked lablab beans for maximum safety and digestibility.

Why the Protein Content Matters

What sets lablab bean apart from many plant proteins is that it contains all nine essential amino acids, making it a complete protein source — a quality typically associated with animal products. This is why it earns a place among the best protein-rich plant foods for vegans and vegetarians. With 25–28 grams of protein per 100g (dried), it rivals chickpeas and lentils in protein density while offering superior iron and calcium content.

Moreover, lablab bean contains minimal fat and zero cholesterol. Thus, it makes an excellent choice for heart-healthy diets.

 

7 Evidence-Based Health Benefits of Lablab Bean

1. Supports Heart Health

Lablab bean is exceptionally heart-friendly. It’s high soluble fibre content actively binds to LDL (“bad”) cholesterol in the digestive tract and helps remove it from the body. Studies on legume-rich diets consistently show reduced risk of cardiovascular disease, and the lablab bean contributes to this effect significantly.

The potassium in lablab bean also plays a key role in blood pressure regulation. Potassium counteracts the effects of sodium in the diet, helping to relax blood vessel walls and maintain healthy blood pressure levels. With zero cholesterol and minimal saturated fat, it is one of the most heart-supportive foods you can include in your weekly meals.

2. Manages and Prevents Type 2 Diabetes

Lablab bean has a low glycemic index (GI), which means it causes a slow, gradual rise in blood sugar rather than a sharp spike. This makes it especially valuable for people managing Type 2 diabetes or those at risk of developing it.

The combination of complex carbohydrates, dietary fibre, and protein in lablab bean slows down digestion and glucose absorption. This helps keep blood sugar stable throughout the day and reduces the need for sudden insulin surges. Replacing high-GI foods like white rice or refined bread with lablab bean is a practical, delicious way to manage glycemic load.

3. Boosts Immune System Function

Lablab bean is rich in antioxidants, including flavonoids, polyphenols, and Vitamin C, all of which actively protect cells from oxidative stress and free radical damage. Free radicals are unstable molecules that contribute to ageing, chronic inflammation, and the development of diseases, including cancer.

Its folate content is also critical for immune function, as folate supports the production and maintenance of new cells — including the white blood cells that form the foundation of your immune response. If you are looking to strengthen your immunity through food, lablab bean deserves a regular place in your diet alongside other immune-boosting plant-based foods.

4. Supports Digestive Health

The dietary fibre in lablab bean acts as a prebiotic — it feeds the beneficial bacteria living in your gut. A healthy gut microbiome is linked to improved digestion, better mood, stronger immunity, and even reduced risk of colon cancer.

Regular consumption of lablab bean prevents constipation, reduces bloating, and promotes regular bowel movements. For anyone dealing with digestive issues, introducing this fibre-rich legume gradually into your diet — starting with small portions and increasing over time — can make a noticeable difference.

5. Aids Weight Management Naturally

Few foods are as satisfying per calorie as legumes — and lablab bean is among the best. The combination of high protein and high fibre makes it extremely filling. When you eat a meal containing lablab beans, you feel full for longer, which naturally reduces overall calorie intake throughout the day.

At approximately 115–130 kcal per 100g cooked, it delivers serious nutritional value without the calorie load. It is also virtually fat-free and cholesterol-free. For anyone following a calorie-controlled plan, our Healthy Diet Guides on Runnar Hut have several lablab bean-based meal ideas that keep you full without going over your targets.

6. Strengthens Bones and Prevents Anaemia

With 100–120 mg of calcium per 100g (dried), lablab bean is a meaningful contributor to bone health — particularly for people who do not consume dairy. Calcium works together with phosphorus to maintain bone density and prevent osteoporosis over time.

Its iron content (6–7 mg per 100g dried) is equally impressive. Iron is essential for the production of haemoglobin, the protein in red blood cells that carries oxygen around your body. Iron deficiency is the most common nutritional deficiency worldwide, and lablab bean offers a powerful plant-based solution. For best iron absorption, pair it with a Vitamin C source — a squeeze of lemon juice on your bean curry works perfectly.

7. Essential Nutrition for Pregnant Women

Folate (Vitamin B9) is one of the most critical nutrients during pregnancy, as it prevents neural tube defects in developing babies. Lablab bean is an outstanding source of folate, with 350–400 mcg per 100g (dried) — nearly the full recommended daily intake for adults in a single serving.

Beyond folate, the iron, calcium, and protein in lablab bean make it an ideal food during pregnancy and breastfeeding. It supports both maternal health and healthy fetal development in one affordable, accessible package.

How to Cook Lablab Bean: Step-by-Step Guide

Cooking lablab beans from dried form requires a little preparation, but the process is simple once you know the steps.

Important Safety Note

Raw lablab beans contain cyanogenic glycosides — compounds that can release cyanide in the body if consumed raw. They also contain lectins and phytates that inhibit nutrient absorption and cause digestive discomfort. Always soak and thoroughly cook lablab beans before eating. Never consume them raw or undercooked.

Preparation Steps

Step 1: Soak overnight. Rinse dried beans under cold water to remove any dust or debris. Cover with plenty of cold water — beans will expand to nearly double their size — and soak for 8–12 hours or overnight. This step reduces cooking time, removes some anti-nutritional compounds, and makes the beans easier to digest.

Step 2: Drain and rinse. Discard the soaking water and rinse the soaked beans thoroughly with fresh water. The soaking water contains leached anti-nutritional compounds and should not be used for cooking.

Step 3: Boil vigorously. Place beans in a pot with fresh water at a ratio of 1:3 (beans to water). Bring to a rolling boil and cook for at least 30–40 minutes until completely tender. A pressure cooker reduces this to 12–15 minutes. The beans should be soft enough to crush easily between two fingers when done.

Step 4: Season and serve. Once cooked, season with your favourite spices. Lablab bean has a mild, earthy flavour that absorbs seasonings beautifully.

Why Scientists Are Calling Lablab Bean a Future Superfood

Food security is one of the defining challenges of the 21st century. Climate change is making traditional growing conditions more unpredictable, and conventional crops like wheat, rice, and maize are increasingly vulnerable to drought, heat stress, and soil degradation.

Lablab bean thrives in exactly the conditions where other crops fail:

Drought resistance: The deep root system of lablab bean allows it to access subsoil moisture unavailable to shallow-rooted crops. It can survive extended dry periods that would destroy chickpeas or soybeans.

Soil improvement: As a legume, lablab bean fixes atmospheric nitrogen through root bacteria, naturally fertilising the soil. Farmers who grow it as a rotation crop often reduce their fertiliser costs significantly.

Low input requirements: It grows well in poor soils without heavy irrigation or chemical inputs — making it accessible to smallholder farmers in developing countries.

Whole-plant utility: The entire plant is useful. Pods are eaten as vegetables, dried seeds as protein-rich pulses, leaves as animal fodder, and the plant itself as green manure.

Affordability: Unlike imported superfoods, lablab bean is locally grown across Asia and Africa, making it affordable and accessible to communities that need nutrient-dense food the most.

Researchers at institutions including the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) are actively developing improved lablab bean varieties with higher yields and enhanced nutritional profiles. The scientific consensus is clear: lablab bean is not just a traditional food — it is a critical crop for a sustainable food future.
