Several types of mushrooms have been shown to have health benefits, but the one with the most evidence of benefits is the shiitake mushroom. Shiitake mushrooms are a rich source of beta-glucans, a type of fiber that has been shown to help boost the immune system, lower cholesterol levels, and improve heart health. They are also a good source of vitamins B and D, and minerals such as selenium and copper. Reishi mushrooms are also believed to have a number of health benefits, including improving immunity, reducing stress, and regulating blood sugar levels. Maitake mushrooms have been shown to have anti-tumor properties and may also help regulate blood sugar levels. In addition to shiitake, reishi, and maitake mushrooms, other types of mushrooms that are commonly consumed for their health benefits include cordyceps, agaricus, and lion's mane. However, it's important to note that the health benefits of mushrooms can vary depending on the species and how they are prepared and consumed. As with any food, it's best to consult with a doctor or registered dietitian for personalized advice.
