Cultivating Plants for Optimal Gut Microbiota Health Enhancement

In the realm of human health, the microbiome plays a pivotal role. This diverse community of microorganisms, residing in our digestive tract, on our skin, and throughout our airways, supports digestion, nutrient absorption, immune system function, metabolism, and even influences mood and brain function [1][2][3][5].

A healthy microbiome, established early in life, can significantly reduce the risks for chronic illnesses such as autoimmune diseases and metabolic disorders [3]. One of the ways to foster a healthy microbiome is through gardening and consuming fresh produce from healthy soil.

Gardening exposes humans to a rich diversity of environmental microbes, especially those found in healthy soil. When people garden or consume fresh vegetables from healthy soil, they ingest diverse microorganisms that can enrich and diversify their own microbiome. This microbial exchange supports the robustness of the gut microbial community and, consequently, overall health [2][4].

Moreover, gardening promotes contact with the living soil microbiome—a complex ecosystem that sustains plant health, nutrient cycles, and indirectly human health by maintaining the quality of food grown in that soil [2][4].

Some examples of edible plants that are beneficial for the gut microbiome include Fagopyrum esculentum (buckwheat), Vicia faba 'Crimson Flowered' (broad bean), Hemerocallis 'Ariadne' (day lily), Rubus fruticosus 'Loch Tay' (blackberry), Malus domestica 'Laxton's Superb' (apple), and many native wildflowers. These plants, when incorporated into our diets, can provide prebiotic fibre, plant protein, polyphenols, and mucilage, all of which support a healthy microbiome [2].

In creating an edible garden, there's no need to stick to regimented lines. We can mix edibles and colorful vegetables among existing ornamental plants. A diverse mix of plants is essential for supporting our microbiome, and consuming at least 30 different plants per week is recommended [6].

Chicory, musk mallow, and bistort are some of the favorite edible wildflowers for a wide range of growing conditions. These wildflowers, along with other plants like Helianthus annuus 'Alchemy' (sunflower), Malva moschata (musk mallow), Ribes nigrum 'Big Ben' (blackcurrant), Bistorta officinalis 'Superba' (bistort), Cichorium intybus (chicory), and many others, can be incorporated into our diets to boost our microbiome and overall health.

Research indicates that gardeners typically possess more diverse and healthier microbiomes than non-gardeners [7]. This could be due to the increased exposure to diverse soil microbes and the consumption of a wider variety of plants.

In no-dig gardening, a thick layer of overlapping cardboard and 10cm of compost or wood chips is used to build soil, provide a habitat for the soil microbiome, and suppress weeds. This method of gardening can help maintain a healthy soil ecosystem, which in turn supports a diverse and healthy microbiome.

In conclusion, gardening and consuming a diverse range of edible plants can significantly contribute to a healthy microbiome. Eating a wide variety of plants is essential for our health, and incorporating these practices into our lives can lead to better health outcomes.

1. Gardening, especially with healthy soil, can introduce diverse environmental microbes into a person's microbiome, promoting a healthy gut community and overall well-being.
2. Consuming fresh produce from gardening, such as buckwheat, broad beans, day lilies, blackberries, apples, and various native wildflowers, can provide essential nutrients that support a healthy microbiome.
3. Incorporating a variety of plants into our diet, ideally at least 30 different plants per week, is essential for maintaining a healthy microbiome and overall health.
4. Some wildflowers, like chicory, musk mallow, bistort, and sunflowers, are great choices for boosting the microbiome when incorporated into meals.
5. A study on gardeners found that they typically possessed more diverse and healthier microbiomes than non-gardeners due to increased exposure to diverse soil microbes and consumption of various plants.
6. No-dig gardening, using a thick layer of cardboard and compost or wood chips, helps maintain a healthy soil ecosystem, which in turn supports a diverse and healthy microbiome.
