Recently, as interest in immunity has grown, 'beta-glucan' has been drawing a great deal of attention. Beta-glucan is also a major component of chaga mushroom. But are the beta-glucan in health functional foods, which are easily found on the market, and the beta-glucan in chaga mushroom really the same?
To state the conclusion first, the efficacy of beta-glucan differs greatly depending on 'where it is derived from' and 'what structure it has.' Today, let's look into the secret of beta-glucan and why consuming it as nature intended is important.
1. Yeast vs. Chaga Mushroom: The Decisive Difference by Raw Material
Beta-glucan is a type of polysaccharide that exists in the cell walls of mushrooms, yeast, grains, and so on. However, not all beta-glucan helps immunity. The key that awakens immune cells is precisely a specific structure called 'beta-1,3/1,6-glucan.'
Many health functional foods on the market mainly use beta-glucan extracted from 'yeast.' This is because yeast is easy to mass-produce and inexpensive. However, yeast-derived beta-glucan has short branches in its molecular structure and takes a relatively simple form.
On the other hand, the beta-glucan of medicinal mushrooms like chaga boasts a far more complex and massive structure. Its long branches are tangled together, and its molecular weight is large, so in aqueous solution it forms a 'triple helix structure' in which three strands of chains are twisted together. Our body's immune cells evolved to recognize precisely this three-dimensional triple helix structure as an 'invading enemy (pathogen).'
In other words, the more complex and three-dimensional the structure, the more strongly immune cells respond, and the greater our body's ability to defend itself becomes. Even though the beta-glucan of yeast and mushrooms share the same name, the influence our body receives is entirely different.
2. The Regret Brought by Artificial Manufacturing Processes
Then what about the high-purity beta-glucan that comes out as a health functional food? It is easy to think, 'Wouldn't higher purity be better?' but there is a trap here.
To extract the beta-glucan present in yeast cell walls, some factories use strong acids or alkaline solutions, boil it at high temperatures, or go through a process of breaking it down with powerful ultrasound. Such processes may be effective at increasing purity by removing impurities, but they cause the core of beta-glucan — the 'triple helix structure' — to come undone.
It is just like a rope that had been firmly twisted coming untied. Beta-glucan whose structure has come undone cannot properly bind with immune cells, making it difficult to fully produce the expected immune-activating effect. Even if the content figures on the ingredient list are high, the ability to actually work inside our bodies may be lower.
Also, in the case of some products, excipients such as 'maltodextrin' are mixed in to create the product's form. Such additives can rapidly raise blood sugar or interfere with the activity of beneficial bacteria in the gut, so it should be noted that a product taken for health may actually place a burden on gut health.
3. The Wisdom of Nature, the 'Entourage Effect' of Chaga Mushroom
Chaga mushroom in its natural state does not simply contain beta-glucan alone. Enduring the harsh cold of Siberia and absorbing the nutrients of birch trees for more than 15 years, it possesses a mass of ingredients unique to chaga called the 'chromogen complex.' Within this complex, beta-glucan whose triple helix structure is fully preserved is densely intertwined together with betulinic acid derived from birch, triterpenoids such as inotodiol, melanin and polyphenols that are powerful antioxidants, and various essential minerals.
When these various ingredients act together, the 'entourage effect (synergy effect)' appears, in which 1 plus 1 is not 2 but 10.
In a health functional food with only a single ingredient extracted, such cooperative action cannot be expected. Helping and complementing one another to maximize efficacy is possible only within the complex ingredients made by nature, and chaga mushroom is truly nature's gift that allows us to make the most complete use of beta-glucan, the byword for immunity.
The Wisdom of Seeing the Forest, Not the Tree, and a Wise Choice
We often focus only on the content numbers of a specific ingredient. But our bodies are not as simple as machine parts. Rather than taking beta-glucan alone, separated out by itself, our bodies show a healthier and more balanced response when we take it together with the various ingredients nature has blended.
Beta-glucan with its 'triple helix structure' — the core of immunity — still alive, and the natural state in which countless helpers that assist it are present together. This is precisely why we should pay attention to nature's complex ingredients rather than artificially refined products. For the choice of health, we need the wisdom to look first at the harmony of nature contained within, rather than at the numbers.
