Researchers developed a healthier cookie recipe by adding Tricholoma matsutake mushroom powder and colored rice flour to regular cookie dough. These additions increased the nutritional value, created better flavors and aromas, and slowed down how quickly the body digests the carbohydrates in the cookies. The best recipe combined 5% mushroom powder with 20% red rice flour, creating cookies that taste good while offering potential health benefits for people concerned about blood sugar and cholesterol levels.
