This research examines how β-glucans, natural compounds found in mushrooms and other fungi, can help boost the immune system and potentially fight cancer. While these compounds don’t directly kill cancer cells, they work by enhancing our body’s natural defense mechanisms. Impact on everyday life: • Provides scientific support for the traditional use of medicinal mushrooms in supporting immune health • Offers potential natural complement to conventional cancer treatments • Helps explain how certain dietary components may contribute to better health outcomes • Suggests new directions for developing safer cancer treatments with fewer side effects • Demonstrates the importance of quality control in natural health products
