The 11 Healthiest Beans and Legumes Compared

Last updated on March 22, 2026 at 07:54 pm

If there is one food group I would tell anyone to eat more of — without hesitation, regardless of their dietary approach — it is legumes.

I have several personal reasons to be consistent about this, and I’ll be honest about all of them because I think they’ll resonate with more people than you might expect.

I have a chronic iron deficiency — something that requires ongoing attention, particularly as someone who does a lot of sport and wants to keep energy levels high. I’ve had kidney stones made up of oxalate, which means I need to be mindful of high-oxalate foods and focus on low-oxalate sources of key nutrients. And having crossed into my forties, I am increasingly intentional about building and maintaining muscle — which means protein is a priority at every meal, and plant-based protein sources have become central to how I eat.

Legumes tick all three boxes simultaneously. They are among the best plant sources of iron. They are low in oxalate, making them safe and beneficial for anyone with a history of kidney stones. And they are protein-rich, with a quality and amino acid profile that genuinely supports muscle building and recovery.

Chickpeas are a permanent fixture in my kitchen — I keep them dried in a large jar, soak them overnight, and cook a big batch at the start of the week. Edamame is my go-to gym snack, ready in minutes from the freezer. And lentils, black beans, and butter beans rotate through soups, grain bowls, and stews throughout the week.

In this article I’ll walk through the 11 healthiest beans and legumes, explain what makes each one nutritionally valuable, and give you the practical knowledge to use them confidently in your own kitchen.

Beans and legumes — what’s the difference?

Legumes is the broader term — it refers to any plant in the Fabaceae family, including the plant itself, its pods, and its seeds. Beans are a specific type of legume seed. So all beans are legumes, but not all legumes are beans. Lentils, peas, and peanuts are legumes but technically not beans.

For practical kitchen purposes the distinction rarely matters. What matters is that the entire family — beans, lentils, peas, chickpeas, edamame — shares the same impressive nutritional profile and deserves a regular place on your plate.

Why legumes deserve a place in your kitchen every single week

The nutritional case for legumes is genuinely exceptional. A regular serving delivers:

Protein — a quarter cup of cooked legumes contains roughly the same protein as a small piece of meat or chicken, with no saturated fat and far more fibre
Iron — one of the best plant-based sources available, particularly important for anyone with low iron levels or anyone who eats little red meat
Fibre — both soluble and insoluble, feeding your gut microbiome, supporting digestion, and keeping you genuinely full for hours
Complex carbohydrates — slow-releasing energy that stabilises blood sugar rather than spiking it
Magnesium, potassium, zinc, and folate — minerals essential for heart health, bone density, immunity, and cell repair
Low oxalate content — making them an excellent choice for anyone managing kidney stone risk or following a low-oxalate diet
Virtually no fat — and what fat is present is predominantly unsaturated

For heart health, the magnesium and potassium in legumes help regulate blood pressure, and the fibre actively reduces LDL cholesterol. For blood sugar management, legumes have one of the lowest glycaemic indices of any carbohydrate-containing food — the American Diabetes Association specifically recommends them. And for gut health, legumes are among the most valuable prebiotic foods available, feeding the beneficial bacteria that underpin immunity, mood, and overall wellbeing.

A note on iron absorption from legumes

This matters to me personally, so it’s worth explaining properly. Legumes contain non-haem iron — the plant form of iron, which is less readily absorbed by the body than haem iron from meat. However, there are two things that significantly improve absorption:

Soaking dried legumes overnight — this reduces the phytic acid content that inhibits iron absorption, meaning you extract meaningfully more iron from soaked and cooked dried legumes than from canned ones. This is exactly why I always use dried rather than canned where possible.
Eating vitamin C-rich foods alongside — a squeeze of lemon on your lentil soup, tomatoes in your chickpea stew, or a handful of fresh parsley on top all significantly enhance iron absorption. It’s a simple habit that makes a real difference.

A note on legumes and kidney stones

If you have a history of oxalate kidney stones — as I do — you’ll know that managing oxalate intake is an ongoing consideration. The good news is that most legumes are either low or moderate in oxalate, making them one of the safest and most nutritious food groups for anyone on a low-oxalate diet. Lentils, chickpeas, and most beans are well tolerated. The ones to be more mindful of are peanuts and soybeans in large amounts — but edamame in moderate portions, as a snack, is generally fine.

A note on legumes for muscle building after 40

This is something I think about a lot. Once we pass 40, muscle mass naturally begins to decline — a process called sarcopenia — unless we actively counter it through resistance training and adequate protein intake. I train regularly at the gym, and making sure I eat enough protein at every meal is a genuine priority.

Plant-based protein absolutely supports muscle building — the research is clear on this, and it is something we cover in depth in the Plant-Based Athlete course. Legumes are one of the cornerstones of that approach. Edamame and lentils in particular are protein-dense enough to anchor a post-workout meal. Combined with a whole grain like quinoa — which is also a complete protein — you have everything your muscles need to recover and grow.

The 11 healthiest beans and legumes

1. Chickpeas — the most versatile legume in my kitchen

My absolute staple. I soak a large batch of dried chickpeas overnight every week and cook them on Sunday alongside my grains. They go into everything — roasted with olive oil and smoked paprika as a crunchy snack, blended into hummus, tossed through a freekeh grain bowl, added to vegetable soups, or stirred into a tomato-based stew with spinach and spices.

Nutritionally they’re exceptional: high in protein and fibre, rich in iron, folate, and phosphorus, with a low glycaemic index and strong prebiotic properties. One of the most complete and affordable whole foods you can buy.

2. Lentils — the fastest legume to cook

Lentils are the weeknight hero of the legume world — unlike most dried beans, they require no soaking and cook in just 20–30 minutes. Red lentils dissolve into a creamy dahl or soup. Green and brown lentils hold their shape beautifully for salads and grain bowls. Black (beluga) lentils have a wonderful earthy depth and look stunning on a plate.

Lentils are among the richest plant sources of iron — particularly valuable for anyone with low iron or anyone eating little red meat. High in folate, protein, and both types of fibre, a bowl of lentil soup is one of the most nourishing, filling, and affordable meals you can make.

3. Edamame — the gym snack that actually works

Edamame are young, immature soybeans — harvested before they harden — and they are my go-to post-gym snack. A small bowl of edamame straight from the freezer (steamed in minutes) delivers around 11g of protein per 100g alongside fibre, vitamin K, folate, and manganese. Quick, satisfying, and nutritionally serious.

Unlike most legumes, edamame contains all nine essential amino acids, making it a complete protein — the same quality as animal protein, from a plant source. For anyone focused on muscle recovery and building, this is worth knowing.

4. Black beans — the heart health legume

Black beans have a rich, slightly earthy flavour and a creamy texture that works beautifully in Mexican-inspired dishes, grain bowls, and soups. Their deep colour comes from anthocyanins — the same antioxidants found in blueberries — which contribute to cardiovascular protection. High in protein, fibre, and folate, with research showing meaningful reduction in heart disease risk with regular consumption.

5. Kidney beans — the filling staple

The backbone of a good chilli and wonderful in rice dishes and hearty salads. High in fibre, protein, magnesium, potassium, and iron. Their deep red colour comes from antioxidant compounds that support cardiovascular health.

One important practical note: raw or undercooked kidney beans contain a compound called phytohaemagglutinin which can cause nausea and digestive upset. Always cook them thoroughly — if using dried, boil vigorously for at least 10 minutes before reducing to a simmer.

6. Navy beans — the fibre champion

Small, white, and mild in flavour, navy beans contain more fibre per serving than almost any other food — around 19g per cooked cup. This makes them exceptional for digestive health, cholesterol management, and sustained satiety. They’re the traditional bean for baked beans and work beautifully in soups, stews, and puréed dips. Their mildness makes them easy to incorporate without changing the flavour of a dish.

7. Pinto beans — the gut-friendly bean

The most widely consumed bean in the US and a staple of Mexican cooking — eaten whole, refried, or mashed. A slightly nutty, earthy flavour with a creamy texture when cooked. High in fibre and protein with particularly strong benefits for digestive health and bowel regularity. Their folate content makes them valuable during pregnancy, and their complex carbohydrates provide long, steady energy.

8. Lima beans (butter beans) — the creamy one

Butter beans — as they’re known in Europe — have a distinctively creamy texture and a mild flavour that absorbs other flavours beautifully. They’ve been a staple in South American cooking for thousands of years and work wonderfully in Mediterranean-style dishes with olive oil, herbs, and vegetables, or simply mashed as a side with a drizzle of good olive oil and a squeeze of lemon.

9. Peas — the underrated legume

Fresh or frozen peas are one of the most overlooked sources of plant protein — yet a cup provides around 8g of protein alongside meaningful amounts of vitamins C and K, manganese, and fibre. Frozen peas are one of the most nutritious convenience foods available. Add them to pasta, soups, grain bowls, or simply warm through with a little butter and mint as a quick side dish.

10. Adzuki beans — the digestion-friendly bean

Small, deep red beans widely used in Asian cooking, particularly in Japan and China where they’re often made into a sweet paste. High in protein and fibre, easy to digest — making them a good choice for anyone with a sensitive gut — and they absorb slowly into the bloodstream, making them excellent for blood sugar management. Their mild, slightly sweet flavour works in both savoury and sweet applications.

11. Alfalfa sprouts — the sprouted legume

Alfalfa is primarily eaten in its sprouted form — soaked for 3–5 days until the seeds sprout and develop a satisfying crunch and fresh flavour. Nutritionally concentrated, particularly rich in vitamin K and plant compounds with antioxidant properties. Sprouting your own at home is genuinely easy — just a jar, water, and a little patience. Add the sprouts to salads, sandwiches, or grain bowls for texture and a fresh nutritional boost.

How to get the most from dried legumes

I use dried legumes rather than canned as my default — and the main reason is iron. Soaking dried legumes overnight significantly reduces the phytic acid that inhibits iron absorption, meaning you get meaningfully more nutritional value from the same bean. It also improves digestibility and reduces cooking time.

The process is simple:

Soak overnight — cover generously with cold water and leave for 8–12 hours. I set this up the same evening I prep my chia pudding — it takes 30 seconds and sets the next day up well.
Rinse thoroughly before cooking — discard the soaking water completely.
Cover with fresh water — about twice the volume of beans — and bring to a boil.
Simmer until tender — lentils take 20–30 minutes, chickpeas 60–90 minutes depending on age and variety.
Season at the end — adding salt too early toughens the skins.
Add something vitamin C-rich to the finished dish — lemon juice, fresh tomatoes, or parsley — to maximise iron absorption.

Batch cook legumes on Sunday alongside your grains. A pot of cooked chickpeas or lentils in the fridge opens up multiple quick, nourishing meals during the week with almost no effort at the point when you’re actually hungry and time is short.

Canned legumes are a perfectly good backup — just look for no-added-salt versions and rinse well before using.

The bottom line

Legumes are one of the most nutritious, affordable, and versatile food groups available — and for anyone dealing with low iron, kidney stone history, or a focus on plant-based muscle building, they are not just a good choice. They are an essential one.

Start with the one or two that appeal most to you. Chickpeas and lentils are the easiest entry point for most people — endlessly versatile, quick to find, and genuinely delicious when cooked well. Soak dried legumes overnight when you remember. Keep a can in the cupboard for when you don’t. Batch cook a pot on Sunday. And add something with vitamin C to every legume dish — your iron levels will thank you.
