We continue with the “a mushroom a week” project. This time, we will talk about the shiitake mushroom, naturally cultivated on oak logs, just as we have been doing at FungiNatur for over 10 years.

If you’ve ever heard of shiitake but don’t really know what makes it special, this article is for you. We’ll tell you about its origin, why it’s considered a superfood, its health benefits, and most importantly, how to distinguish a high-quality shiitake naturally grown on oak logs from industrially cultivated ones. Plus, you’ll discover how to easily incorporate it into your diet and why FungiNatur’s shiitake is a unique and superior choice.
A mushroom with history and a curious name

Shiitake is far from a modern invention. It has been cultivated in Asia for over 1,000 years, particularly in China and Japan, where it has always been highly valued for both its flavor and nutritional properties.
Its name comes from Japanese and has a simple explanation: “shii” refers to a type of tree similar to oak, where it naturally grows, and “take” means mushroom. So, literally, “shiitake” means “mushroom of the shii tree.”
What’s even more fascinating is that in ancient China, this mushroom was considered a food for longevity. It is said that emperors consumed it regularly, believing it helped them live longer and stay strong. And based on what we know today about its benefits, they might not have been wrong.
What makes FungiNatur’s shiitake special

Now, not all shiitake mushrooms are the same. Most of those sold in supermarkets are grown on substrates enriched with sugars, yeasts, and agricultural residues, in a completely industrialized process. This means they grow quickly but lose some of their most beneficial properties.
At Fungi natur, we are committed to a more natural and traditional cultivation method: we grow our shiitake on oak logs, in the open air, within our own forest, and without rushing the process. This method mimics their natural environment, allowing the mushrooms to better absorb the nutrients from the wood. As a result, our shiitake has a richer flavor, a better texture, and enhanced health benefits.
How to distinguish a naturally grown shiitake from an industrial one?

If you have ever compared traditionally grown shiitake to industrially cultivated ones, you’ve probably noticed some clear differences. Here are some key points to help you identify them:
appearance and texture:
- shiitake grown on oak logs has a more robust, meaty, and appetizing appearance. Its cap is thicker and has a firm texture, making it more flavorful when cooked.
- industrial shiitake tends to be thinner, lighter in color, and less appealing. It is softer to the touch and often loses consistency when cooked.
aroma and flavor:
- oak-grown shiitake has a more intense and natural aroma, with deep earthy notes. Its flavor is richer and more concentrated.
- industrial shiitake has a much weaker aroma and a milder taste, making it less interesting in cooking.
nutritional differences:
- If analyzed in a lab, shiitake grown on oak logs would show higher concentrations of polysaccharides (such as lentinan), more antioxidants, and a greater number of bioactive compounds compared to industrially grown shiitake.
- This means that, beyond the visual differences, oak-grown shiitake is far superior in terms of health benefits.
in summary; if you are looking for a mushroom with authentic flavor and all its properties intact, shiitake grown on oak logs is the best choice.
The properties of shiitake: much more than just a mushroom

- Boosts the immune system: It contains beta-glucan polysaccharides, especially lentinan, which help strengthen the immune system. These compounds stimulate the production of defensive cells, making the body better prepared to fight infections and viruses.
- Anti-inflammatory and antioxidant properties: The antioxidants present in shiitake help neutralize free radicals, reducing oxidative stress and inflammation in the body. This can be key to preventing premature aging and chronic inflammatory diseases.
- Regulates cholesterol levels and protects the heart: Shiitake is a great source of eritadenine, a natural compound that helps reduce LDL (bad) cholesterol levels and improve blood circulation. Additionally, its fiber content supports fat metabolism regulation, reducing the risk of cardiovascular diseases.
- A natural source of vitamin D: Shiitake is one of the few plant-based foods that contain ergosterol, a precursor to vitamin D. When exposed to sunlight, this compound converts into vitamin D2, which is essential for bone health and immune function. It is an excellent option for those who do not consume dairy products or have a vitamin D deficiency.
- Supports gut microbiota: It provides fiber and prebiotic compounds that promote the growth of beneficial bacteria in the intestine, helping improve digestion and strengthening the digestive system.
- Boosts energy and vitality: Thanks to its content of B vitamins, minerals like zinc and selenium, and plant-based proteins, shiitake is an excellent food for those looking to stay active and improve physical and mental performance.
- May contribute to cancer prevention: Lentinan and other compounds found in shiitake have been studied for their potential effect in inhibiting the growth of tumor cells. While it is not a treatment on its own, regular consumption may be a valuable complement to a healthy diet.
How to enjoy it in your daily life

If you’ve never tried it, here are some simple ideas:
- Sautéed with garlic and ginger – A classic with an Asian touch.
- In soups or broths – Perfect for cold days.
- In omelets or scrambled eggs – Adds extra flavor and nutrients.
- As an infusion or in powdered form – Ideal for easily enjoying all its benefits.
How much to take?
Fresh: 50 to 100 grams per day.
