In autophagy, “the body identifies old and defective cell components and marks them for destruction” (according to MentalFoodChain). This happens during fasting, for example, when the body does not have enough energy to maintain broken down cell parts. Coffee can also trigger autophagy. The prerequisite for this: You drink coffee without milk. According to the study from Graz, animal proteins can inhibit the autophagy processes.

“Vegetable protein, especially in soy and wheat, strongly stimulates autophagy. This is because these foods are very high in spermidine. A polyamine that stimulates autophagy. “

by the way: You can also find spermidine in these foods.
