Our cells are stimulated by proteins in our bodies. These proteins can come from other cells as messages. They can come from our brains as a result of stress or how we think. They can also come from our diet. All food that was living (plant or animal based) is made of protein. These proteins trigger a reaction at the cell’s surface that will result in an epigenetic change. This change will express a gene or set of genes or prevent them from being expressed. The resulting expression builds a new protein that can then go a trigger another cells epigenetics. This programming is very complex. This video shows how this cycle of life works.
