High fibre mushrooms are the perfect microbiome fuel, contributing in big ways to human health and wellness. Making them heroes in our diets ensure that we are protected against pathogens, and that our immune system develops sufficiently to enable us to fully digest food to produce energy.
High in fibre mushrooms are the perfect microbiome fuel
Let’s talk gut fungi, flora and more. Like mushrooms, we all have them … and that’s a very good thing, because the microbiome is key to vibrant, healthy living!
So, what exactly is the human microbiome?
“The microbiome is the collection of all microbes, such as bacteria, fungi, viruses, and their genes, that naturally live on our bodies and inside us,” is the definition from the National Institute of Environmental Health Sciences in the US.“Although microbes are so small that they require a microscope to see them, they contribute in big ways to human health and wellness. They protect us against pathogens, help our immune system develop, and enable us to digest food to produce energy.”
How do we help these life-giving bugs do their rather significant job? According to the personal health programme ZOE, which is based in the UK,
“your diet is a key factor in determining which microbes are in your gut.”
Professor Tim Spector, a co-founder of ZOE and a leading microbiome researcher at King’s College London, stresses that
“there really is no one-size-fits-all approach to nurturing the beneficial microbes in the gut because we all have unique gut microbiomes.”
He does, however, have some tips for best supporting your microbiome:
• Eat more plant-based foods – and that definitely includes mushrooms – because gut microbes feed on fibre. From spices, through oils to coffee and greens and even dark chocolate, 30 different plants per week is the number recommended by Professor Spector for good gut health.
• Eat plants of different colours. “Not only are colourful plant foods rich in fibre, they also contain loads of polyphenols, which ‘good’ gut microbes love,” explains the prof.
• Try fermented foods, including sauerkraut, kimchi and yoghurt. These need to be true ferments and not vinegar-based pickles to be of benefit.
• Leave gaps between eating to give your gut bacteria time to rest and restore the gut lining – so, it may be best to cut down on snacking.
• Eat fewer ultra-processed foods, which can be high in sugar, which does not support gut health, and low in fibre, which is needed for optimal gut health.
What do mushrooms have to do with any of this?
Not only are mushrooms high in fibre, making them perfect microbiome fuel, but
“mushrooms act as prebiotics to stimulate the growth of gut microbiota, conferring health benefits to the host” concluded a 2017 scientific review in the US National Library of Medicine. In addition, a 2023 Chinese study published in the US National Library of Medicine found that “mushroom polysaccharides could promote human health by regulating gut microbiota, increasing the production of short-chain fatty acids, improving intestinal mucosal barrier, regulating lipid metabolism and activating specific signalling pathways.”“Mushroom polysaccharides,” it explained, “are a kind of biological macromolecule extracted from the fruiting body, mycelium or fermentation liquid of edible fungi.”
These
“polysaccharides are an important active ingredient of mushrooms, which are not absorbed by the gastrointestinal tract and can only be fermented by gut microbiota in the large intestine. Mushroom polysaccharides can also specifically change the composition and abundance of gut microbiota and maintain intestinal microecological balance.”
Of course we’re not referencing some obscure, hard to procure fungi here. These findings apply to the white button, portabellini and large portabello mushrooms easily found in South African supermarkets. In reality, the health benefits of common mushrooms are many and varied. A 2021 review of the bioactive compounds with health benefits of edible mushrooms hailed them as being
“well recognised for their nutritional importance such as high protein, low fat, and low energy contents.”
They are also known to be “rich in minerals such as iron, phosphorus, as well as in vitamins like riboflavin, thiamine, ergosterol, niacin and ascorbic acid. Furthermore, they contain bioactive constituents like secondary metabolites (terpenoids, acids, alkaloids, sesquiterpenes, polyphenolic compounds, lactones, sterols, nucleotide analogues, vitamins, and metal chelating agents) and polysaccharides, chiefly β-glucans and glycoproteins.
“Due to the occurrence of biologically active substances, mushrooms can serve as hepatoprotective, immune-potentiating, anti-cancer, anti-viral, and hypocholesterolemic agents. They have great potential to prevent cardiovascular diseases due to their low fat and high fibre contents, as well as being foremost sources of natural antioxidants useful in reducing oxidative damages.”

Mushroom Savoury Oats
Image and Recipe Credit: The South African Mushroom Farmers' Association
Serves 4
Ingredients:
4 large eggs
2 shallots, finely diced
500g mushrooms
2 Tbsp sherry vinegar
2 cups rolled oats
4 cups chicken stock, kept warm
50g parmesan cheese, finely grated
2 Tbsp butter
2 Tbsp micro herbs
2 spring onions, finely sliced
Extra parmesan, for garnish
Olive oil, for cooking
Salt and pepper, to taste
Method:
Bring a small pot of water to the boil.
Add the eggs and stir.
Cook for 6.5 minutes.
Remove the eggs and place in ice water to stop the cooking.
Peel and set aside - slice only just before serving.
Heat a drizzle of olive oil in a large saucepan over medium heat.
Add mushrooms and cook until golden.
Remove two spoonfuls for garnish.
Add shallots and cook until tender.
Pour in the vinegar and cook for a minute.
Add in all the oats and half the stock.
Stir constantly and bring to a simmer.
As the oats absorb the liquid, slowly add in the rest of the stock as you would to make a risotto, stirring the whole time.
Once all the liquid has been absorbed, add the cheese and butter.
Season to taste with salt and pepper.
Divide the oats among 4 warm bowls.
Garnish the tops with the reserved mushrooms.
Finish with the sliced eggs, spring onions and micro herbs.
Serve and enjoy!
