Plant sterols and sterolins are plant fats found in all plant-based foods.  Sterolins are known as glucosides, which are molecular structures joined to the sterols. Sterolins are easily destroyed and without it the sterol does not have the same immune-enhancing benefits. Plants can never contain sterols alone. Sterols and sterolins allow the immune system to regulate itself: upregulating an underactive response and downregulating an overactive one. When we are exposed to stressors, our adrenal glands secrete the stress hormone cortisol, causing a corresponding drop in our anti-aging and immune enhancing hormone dehydroepiandrosterone (DHEA). Plant nutrients called sterols and sterolins effectively modulate cortisol, control Interleukin-6 and naturally increase DHEA to combat the pro-inflammatory effect of the imbalances in the body and thus enhances our immunity to fight a fair fight.
