Mushrooms themselves do not produce heat in the human body. They are a food source, and their consumption does not inherently generate heat. However, the metabolic processes that occur in your body when you digest and metabolize food, including mushrooms, can lead to a slight increase in body temperature. This increase in body temperature is part of the thermic effect of food (TEF) or diet-induced thermogenesis.
When you eat, your body expends energy to digest, absorb, and metabolize the nutrients in the food, which can lead to a temporary, modest rise in body heat. This effect is similar for all types of foods, not just mushrooms.
It’s important to note that the increase in body temperature due to eating is generally not significant and is a normal part of the body’s energy expenditure processes. Any notion of “heat” produced by mushrooms or other foods should not be confused with the idea of foods causing a significant increase in body temperature, as seen in the case of fever or external heat sources.
