Weeds: Real Nutrition, for Free

Reading time: about 4 minutes | First published 25th Jul, 2020 | Updated 21st Aug, 2024

If you’re walking over chickweed and dandelion in your lawn or ignoring a nettle patch by the garden wall as you hop in the car and drive to the grocery store and pharmacy, you’re passing up opportunities for a quality of nutrition that no plastic wrapped package or bottle of capsules can ever provide.

When our grandparents were told, “eat your veggies,” that was good advice. But nowadays there are veggies, and then there are other veggies. In terms of nutrition, they’re not all created equal.  

Imagine a graph that measures nutrition. At the bottom there is relatively little, and at the top there’s lots.

graph comparing nutrition in supermarket veggies, heirloom vegetables, and wild edibles or weeds

On this graph, I'd place supermarket vegetables at the bottom, heirloom varieties of vegetables and herbs from home gardens, community gardens, and small, diverse farms in the middle, and wild/undomesticated edibles (many of them known as “weeds") at the top.

Supermarket veggies - where did the variety and nutrition go?

The food plants we see in the supermarket represent a tiny sliver of all the food plants there are. 

There are over 20,000 species of edible plants in the world. Fewer than 20 of them now provide 90% of our food."

Besides being a very narrow selection of the plant foods available to us, supermarket vegetables are the least nutritious veggies you could be eating. They almost ( through no fault of their own) shouldn't be called by the same name/ 

One of the reasons for this is that they’re bred for appearance and shelf life rather than nutrition or vigor. Another is that they’re usually grown in mono-cultures using synthetic, petroleum-based inputs, in impoverished soil that has nothing to offer them in the way of real nutrition. 

But hey, so long as there’s a pharmacy next door to the supermarket we should be right – we can make up with pills for what’s lacking in the veggies…

Heirloom veggies from gardens and small, diverse farms – a big step in the right direction

Just in case you dislike pills as much as I do, let’s explore some more options.

Heirloom food plants grown in home and community gardens or on small farms that focus on diversity, nutrition, and soil health, are a big step in the right direction.

These veggies would never cut it on a supermarket shelf, because this is "real food." Real food means that:

  • you get to enjoy odd shapes, sizes, colors, and quirkiness – these veggies weren’t bred for consistent appearance;
  • you have to eat it or put it in a jar quickly – these veggies weren’t bred for keeping ability;
  • before you eat it or process it you might want to pick out the caterpillars and shake off the spiders – these veggies come from an environment that’s wriggling, kicking, and teeming with life.

You'll get far more nutrition out of these veggies because they grew in a nourished and nourishing environment.

A real food diet

Eating veggies grown in home and community gardens and on small farms might also help you sleep a little easier, knowing that these veggies help you answer "yes" to questions like these:

"Am I making food choices that directly support the communities and ecosystems that  are feeding me?"

"Does whoever is selling this food care about its impact; are they behaving like a responsible citizen?"

"Was it grown nearby and will I be eating it in it's natural season?"

Answering yes to as many of these kinds of questions as you can moves you closer to what I call a real food diet. That is, a diet based on choices that nourish not only you and your family, but also food-growing families and communities and our living planet.

Wild plants take it up another notch

Wild plants--wild edibles or "weeds"--take nutrition up another notch again, because they have a few attributes that domestic plant foods don't have.

Wild plants still have all their wild vigor -- something a bit like what we call the "hybrid vigor" that occurs in cross-bred animals. They can thrive in much more challenging conditions than the plants we've bred selectively for appearance and shelf life, and they pass on some of that vitality and vigor to us when we eat them.

The picture above is of narrow leafed plantain (Plantago lanceolata) persisting in a pavement crack.

Just a weed, right?

Well.

The plantains (there's the narrow leafed and also a broad leafed variety - Plantago major) can be used as first aide for bee stings and minor wounds, they also benefit gut health and skin health, and you can put the young leaves in a salad and the older leaves and the seeds in any veggie dish, soup, or stew.

Not too shabby for a weed in a pavement crack. 

Obviously the one in the pic is looking a bit crushed and you'd want to look around for a happier one if you needed food or medicine, but I chose that picture to make a point: wild plants are tough. They can handle adversity. They take advantage of opportunities and they have ways of hanging on through hard times, ready to burst forth with new life again when the conditions improve. 

A match made in nature, a very long time ago

Archeologists loosely agree that humans began to domesticate first animals and then plants about 10 to 12,000 years ago. In contrast, we were eating wild plants for about 2 million years before that.

Some of the plants we’ve relied on for all of the time we've been human were here before us. Dandelions, for example, are thought to have evolved over 30 million years ago1.  And archeological evidence suggests that at least 45,000 to 80,000 years ago, our ancestors were eating edible and medicinal herbs such as yarrow and camomile2.

In other words, our fore-mothers were relying for nourishment and health care  on the same wild edibles that we now call weeds a long, long time before we began to domesticate the plants we find in supermarkets today.

The wild plants most useful to humans consistently follow people around. (Think of dandelions in lawns, plantain along the roadsides, and amaranth in gateways.)

Wild edibles--called "weeds" whenever they grow where they haven't been explicitly invited to grow--follow us around, colonizing and stabilizing the soil where-ever we've exposed, compressed, or depleted it. And while they're holding and healing our soils they're offering free nutrition to us too, if we choose to gather and use them. 

Our people have a name for [plantain]: White Man’s Footstep. ... It arrived with the first settlers and followed them everywhere they went. It trotted along paths through the woods, along wagon roads and railroads, like a faithful dog so as to be near them.”

Robin Wall Kimmerer, "Braiding Sweetgrass" 

Weeds can help us redevelop the strengths we gradually lost as we made the shift from wild plants to supermarket veggies

As I’m sure you’ve noticed, dandelions are still going strong. They’re still popping up through cracks in the pavement, laughing at the chemicals people spray on their lawns, brightening our days with their sunny flowers, and offering their gifts of food, medicine, and perspective.

"Dandelions have work to do. They are every man’s flower, a poor man’s medicine, a starving man’s food. Despite war and climate change, the rise and fall of civilizations, dandelions have been going strong for 30 million years."

Lilli-anne Buffin, "On Dandelions" 

The wild, edible plants that insist on following us around, with all their vigor and tenacity, are full of bio-available nutrients that our bodies can easily assimilate. If we're willing to relearn how to recognize and gather them, and reacquaint our domesticated pallets with their bitter, tart, or astringent tastes, they're a concentrated source of real nutrition, abundantly full of synergistic vitamins, minerals, and healing compounds. And they’re readily available, for free.

Dandelion leaves, flowers, and seed head. Chickweed is growing beside it.

This picture is of dandelions and chickweed in one of our veggie garden areas. I found a study (scroll down to find tables 7 and 8, here) that showed that chickweed, dandelion, and other wild greens collected in urban and industrial areas outranked kale for nutrition.

(A note on smoothies, since I know that smoothies are one way people like to make use of edible greens. I know this won't endear me to the raw foodies 😉 but here it is: blending up raw plants doesn't break open the plants' cell wall -- meaning that the nourishment therein is unavailable to the human digestive tract. To get the full benefit from eating plant foods you need to cook, ferment, freeze, or dry them first. More on this in the third article in this series.)

Is there a catch to eating weeds? If there is, it's not too onerous. It's that we will have to develop and use some initiative and persistence -- just as the weeds do. (Perhaps they're showing us how.) By paying attention to them and learning to use them again, we can be better nourished and we'll also be redeveloping some of the strengths we gradually lost as we made the shift from wild plants to supermarket veggies.

Wild edible greens harvested in industrial, mixed-use, and high-traffic urban areas ... are abundant and highly nutritious. ... Tested species were safe to eat after rinsing in tap water. ... Wild greens could contribute to nutrition, food security, and sustainability in urban ecosystems.”

  • Hi dear friends.
    I am known as the ‘weed eater’ I can live very humbly and frugally from mother nature.
    I forage beautiful fresh organic leaves, funghi and fruit just walking around my community.
    Chickweed, fat hen, blackberry, Lilli Pilli fruit etc.
    I live in southern Australia ~ Tasmania ~ where we have abundant native foods to forage.
    Enjoy

  • Your article made me smile 🙂 I love the way you related the attributes of weeds to improve your own life.

  • Great article. There are indeed a lot of edible wild plants. I keep discovering them in my property, Parque Bambú, in Ecuador. http://www.bospas.org
    Thanks for your input, keep writing.

    • Thanks for the encouragement and the link, Piet.

  • Hi Kate,
    thanks! We have been promoting our “weeds” for a long time, and more and more people are waking up to these plants’ nutritional value. I repeatedly tell my neighbours, why would we want destroy nature’s diversity and resilience in order to grow a small selection of plants, break our backs, when we can just go pick food? This is the link to our latest illustrated report.

    Best from the islands of Zanzibar, Antje

    • Hi Antje, why indeed? Crazy isn’t it. Thanks for the link!

  • Mary Jeffery says:

    You are absolutely positively correct.
    Your message needs to be broadcast everywhere.
    Silly humans… oblivious to the free nutritious food that would flourish if it wasn’t poisoned, paved-over, sodded, and despised.
    Thank you!!

    • You’re welcome, Mary, thanks so much for commenting.

  • Great article Kate! It’s so liberating knowing some wild edibles, I love that once you know your weeds you can see food EVERYWHERE. I’ve been introducing dandelion seeds to our land lately. I think they prefer a damper climate but I’m hoping they’ll take off in some of the shadier parts.

    • Hi Erika, there were no dandelions here when we came, either. In our case I think its a bit too wet. But I’ve been dropping seeds around, and they’re getting going slowly but surely. Thanks for commenting!

  • Yes weeds are great. I picked some ribwort (narrow leaved plantain) this morning to dry for using in skin healing lotion together with dandelion flowers and calendula. These useful weeds also attract beneficial insects. I find their lush green leaves make an attractive border so I mow a path between and let the ribwort and dandelion form a border. Chickweed is a common addition to my meals and the chickens love them too of course. If I’m making a green smoothie I can easily make up the bulk of it with fresh wild greens and balance it with fruit. I have a permaculture garden and as the seasons change I love to observe the wild or volunteer plants that pop up and seek to identify them and their uses.

    • You’re messing up the system, Marian, don’t you know you’re supposed to get your smoothie ingredients from the grocery section, your chicken food from a bag, and your insect control from a spray bottle? Just kidding, of course. Thanks for your comment and your lovely descriptions.

  • Weeds, weeds, weeds – they’re coming up in my garden and in lots of conversations I’m having lately! I usually only harvest and eat my favourite weeds, maybe it’s time for me to widen my selection… Thanks Kate!

    • You’re welcome, Bel. Thanks for the comment!

  • Terry Laybourne says:

    I am currently in the process of creating a food forest using the principles of permaculture. Your article adds another dimension to what I am creating. Thank you.

    • I’m glad it was helpful, Terry and thanks for the comment.

  • Exellent article, thank you! alas I live in the hot wet tropics where I’m still trying to find out what’s edible and what not… what’s growing in our supermarket is exactly the same as in yours!

    • Hi Refugio, I’m glad you liked the article. I’m not sure from your comment whether you’re saying that where-ever we live in the world the supermarkets stock the same foods because of the globalization of food systems, or if you’re referring to our similar climate and therefore similar food plants. Whichever meaning you intended, I agree with both!

  • Lately I’m focusing on increasing the minerals in my diet, and I’m looking mainly to leafy greens, both domestic and wild, to help me do it – I’ll share more about exactly how I’m going about it in the next post.

    • Great article Kate with the comparison made clear! The Townsville Permaculture Club has a great brochure on edible greens that grow really well in the dry tropics but I gave a talk on edible weeds based largely on what my migrant parents gave us to eat growing up! Stand outs (besides the wonderful Dandelion) are Purslane, Emilia and Milk/Sow Thistle. Isabell Shipard is a great authority (“Self-Sufficiency”)

      • Thanks for your comment, Milena. I received a book voucher for my birthday recently, and Isabell Shipard’s herb and self-sufficiency books are at the top of my list. Does the Townsville Permaculture Club have a website where I could find the brochure you mentioned?

        • I can email you a digital copy. perhaps if you send an email to me I can then reply
