A type of medicinal mushroom, agaricus is often touted as an all-natural immune-booster. Indeed, there's some evidence that agaricus may help stimulate the immune system and even help strengthen your defense against some forms of cancer. However, since most of this evidence comes from animal-based research and test-tube studies, it's too soon to recommend agaricus for cancer defense.
To keep your immune system strong, it's important to follow a diet rich in antioxidants and omega-3 fatty acids, exercise regularly, get plenty of sleep, and keep your stress in check.
