Ah, but what does a healthy person's digestive system look like? Its hard to know as most people's digestive systems have been artificially altered through ingestion of processed foods, pesticides, antibiotics, genetically modified foods, and high carbohydrate nutrient poor foods. One can go through the entire system, step by step, looking at the integrity of structure for each digestivecotgsn, proper biochemical production and microbiome composition. There are interventions to improve structural integrity, improve biochemistry and manipulate microbiome composition. Digestive enzymes are one such intervention. One can't regain health without good attention to optimizing digestive function, but this alone will not cure most of us. It may be a component of a cure, but there are another systems gone awry that need to be righted.
