May promote blood sugar regulation

Oyster mushrooms not only support heart health but may also assist control blood sugar. Taking powdered P. ostreatus decreased post-meal blood sugar levels, according to research including 22 participants with and without type 2 diabetes. According to the authors, the mushrooms boosted the body's utilization of sugar while blocking several proteins that raise blood sugar levels. Eating 150 grams of cooked P. ostreatus every day for seven days lowered fasting blood sugar by 22% and post-meal blood sugar by an average of 23%, according to a 2007 research on 30 hospitalized type 2 diabetics.

Participants' fasting and post-meal blood sugar levels increased on average by 13 and 20 percent, respectively, after stopping the mushroom therapy for a week. Blood pressure, cholesterol, and triglyceride levels of individuals were all considerably lower after the therapy. In addition, therapy with 3 grams of powdered P. ostreatus powder per day for three months significantly decreased hemoglobin A1c (HbA1c), a measure for long-term blood sugar management, in a trial of 27 men with type 2 diabetes and high blood pressure. According to a review published in 2020, the mushroom's high content of beta-glucans, a kind of fiber that slows down carbohydrate digestion and absorption, may be responsible for these possible blood sugar-lowering benefits.
