Research shows that the human body in Bangladesh produces less metabolism. This is due to a lack of protein. There is no protein in the body, but weight is high due to fat. In this state, the immune system is weak because metabolism is not produced. As a result, South Asian people are among the weakest in the world. And this has happened due to the dietary habits of the last 200 years. Before that, the health of people in Bangladesh or South Asia was much better. Mushroom is one of the best sources of protein and other nutrients that contains no cholesterol.
