In the world of plant-based foods, beans reign supreme. In fact, beans are so beloved that there’s even a children’s song promoting their benefits: “Beans, beans, the magical fruit!”

But why are beans so lauded? As it turns out, beans are good for us in all sorts of ways. Not only are they a humble food, often inexpensive to buy and easy to prepare, but they also carry plenty of nutritional benefits.

Beans form an important part of vegetarian and vegan diets largely because they are an excellent source of protein and minerals like calcium and iron. But people who eat meat can also stand to benefit from the fibre in beans, and they contribute to a healthy, varied diet.

Dr Emily Leeming, author of Genius Gut: The Life-Changing Science of Eating for Your Second Brain, tells Yahoo UK: "Beans are packed full of fibre, more than most fruits and vegetables. Most of us in the UK are severely lacking in how much fibre we’re eating, only having just over half of the 30g we need a day.

"For every 7g more of fibre you eat, equivalent to about half a can of chickpeas, is linked to a lower risk of heart disease by 9% and type II diabetes by 6%, and just a third of a can of chickpeas, equivalent to 5g of fibre, is linked to a 5% lower risk of depression.

"Adding beans onto your plate is one of the easiest ways to up your fibre intake for your health. Fibre is essential to feed our healthy gut bacteria that live in our lower intestine, helping them to produce special molecules that support your health across your body, including your brain."

Some types of beans may even be good for our mental health. Botanist Nadia Mohd-Razman spoke of her mission to get Britons eating more broad beans. She told the Observer that broad beans should be more of staple in meals across the country, and is campaigning to promote British broad beans.

Mohd-Razman, a researcher from Cambridge University, said that broad beans contain high levels of levodopa, or L-dopa, a compound that "has been shown to be very effective in treating the condition known as anhedonia, which is essentially the inability to feel or experience pleasure".

"We have a major problem with growing numbers of young people experiencing mental health problems in the UK today, and helping them eat a proper, healthy diet is going to be crucial in tackling this. The broad bean will be our first line of attack," she told the publication.

Broad beans are also sometimes also known as fava beans. According to Hodmedod, which supplies British-grown beans, grains, seeds, and more, fava beans are the dried beans of the Vicia faba species of the legume family, which is the same species as the fresh green broad beans many Britons may be more familiar with.

Broad beans are usually picked fresh, while fava beans are the fully mature fruit of smaller seeded varieties that are left to dry and blacken before they are harvested.

Ricotta and Pesto Butter Beans. (Joe Woodhouse / Bold Bean Co)

Serves: 2-3

Ingredients:

  • 700g jar Queen Butter Beans

  • 250g ricotta (or burrata or stracciatella cheese)

  • Zest of 2 lemons, plus juice to taste

  • Freshly ground black pepper

For the pesto:

  • Large handful of pine nuts, toasted (or walnuts)

  • 30g basil

  • 1 garlic clove

  • 25g Parmesan or vegetarian hard cheese

  • 4-5tbsp olive oil, plus extra to serve

Method:

  1. To make the pesto, add the pine nuts, basil, garlic and cheese to a blender or food processor, along with four tablespoons of the olive oil. Blitz until you have an oozy, puree-like consistency; you may need to add more oil to bind the mixture together.

  2. Next, prepare the beans. In winter, we like serving this as a brothy bean base, so we recommend saving some of the bean stock and warming through the beans in a pan.

  3. For summer, we like it lighter, so simply drain and rinse the beans and don't bother to warm through.

  4. Spoon the beans onto your serving plate and dollop over the ricotta.

  5. Drizzle over the pesto and scatter over the lemon zest, plus a small squeeze of the juice if you like a real zing.

  6. Finish with some cracked black pepper and a final drizzle of olive oil for extra indulgence.

Fava Bean Shakshuka. (The Cook & Him / Hodmedod)

Serves: 2

Ingredients:

  • 1 cup (160g) dried Split Fava Beans

  • 2 cups (500ml) vegetable stock

  • Drizzle olive or rapeseed oil

  • 1 red onion, peeled and diced

  • 1 pepper, seeds removed and flesh roughly diced

  • 4 small cloves of garlic, peeled and crushed

  • 1x400g can peeled whole plum tomatoes

  • 4 sun-dried tomatoes

  • 2tbsp tomato puree

  • 1tbsp coconut sugar

  • 2tsp smoked paprika

  • 2tbsp balsamic vinegar

  • About 1tsp chilli flakes (optional)

  • 10 cherry tomatoes, halved

  • 4 medium organic free range eggs

  • Fresh basil to garnish (optional)

Method:

  1. To cook the fava beans simply put 1 cup split fava beans and 2 cups vegetable stock into a medium saucepan and gently bubble for 30-40 minutes until soft but still with a little bite. Stir frequently to prevent the fava beans sticking to the saucepan. If they start to bubble dry just top up with some more water or vegetable stock.

  2. Pour a drizzle of olive or rapeseed oil into a large frying pan along with the diced onion and peppers and crushed garlic and gently saute for 5 minutes, stirring occasionally till softened.

  3. Add the can of whole peeled tomatoes and ½ can of water.

  4. Then add the cooked fava beans (see note below), sun dried tomatoes, tomato puree, coconut sugar, paprika, balsamic and optional chilli flakes. Stir well then gently bubble for 2-3 minutes.

  5. Stir in the halved cherry tomatoes.

  6. Make a well in one quarter of the mixture. It won't be a completely empty well because of the liquid from the sauce, just push the veg aside to make a rough hole.

  7. Crack in an egg and repeat this with the other 3 eggs in different parts of the pan.

  8. Cover with the lid and cook for another 2-3 minutes until the eggs are set but not overcooked.

  9. Serve immediately garnished with a few basil sprigs and crusty bread.

Warm Carlin Pea 'Hummus'. (Jenny Chandler / Hodmedod)
Warm Carlin Pea 'Hummus'. (Jenny Chandler / Hodmedod)

Serves: 4

Ingredients:

For the 'hummus':

  • 4 tbsp extra virgin olive oil

  • 250g Cooked Carlin Peas, home cooked or from the can

  • 1 heaped tsp Fermented Wholegrain Naked Barley or Fava Bean Umami Paste

  • ½ orange, juiced

  • 1 tsp sherry vinegar, or red wine vinegar can be substituted

  • Salt and pepper, to taste

  • 1 clove garlic, finely sliced

For the salad:

  • ½ red onion, spiced

  • 2 tbsp vinegar (can be substituted with wine, cider, or sherry)

  • ½ tsp salt

  • 1 small head of radicchio or chicory

  • 1 medium beetroot, sliced finely, ideally on a mandolin

  • 2 carrots, roughly chopped

  • 2 oranges, peeled and segmented or sliced

  • 2 handfuls of walnut halves

  • A splash of extra virgin olive oil

  • Black pepper

Method:

  1. Heat the garlic in the olive oil in a small pan until it just begins to colour. The idea is just to reduce the garlic’s bite, bring out the aromas and infuse the oil, you’re not frying so gently does it.

  2. Now add the oil and garlic to a blender with the drained peas (save the cooking/can water), half of your fermented barley (or other source of Umami flavour) and the orange juice.

  3. Blend to a purée, smooth or textured (that’s your choice). Taste and add the remaining fermented barley, vinegar, salt and pepper to taste.

  4. If the purée feels too stiff do add a splash of the cooking/can water to loosen.

  5. When ready to serve you can warm through the “hummus” in your garlic oil pan and then spread onto a serving plate with the back of a spoon.

  6. For the salad, place the sliced red onion in a small bowl with the vinegar and salt, massage it with your finger tips for a few seconds and then set aside to soften and turn a glorious fuchsia pink.

  7. Arrange the remaining ingredients on top of the warm pea purée, top with the onion and then add a drizzle of olive oil, the vinegar from the onion bowl and plenty of freshly ground black pepper.
