Not misleading at all!!

quote: "Your "challenge" is misleading and erroneous. Of course the human body (if healthy) *can* manufacture enzymes.

The point is that to do so requires an enormous amount of energy and is deleterious over the long run to the health and wellbeing of human body.

The less enzymes our food contains, the more our body's have to supply, and the greater the digestive stress on our body" endquote

To follow your logic and beliefs a bit further lets explore some things that msut occur for your statements to be true. If teh body conserves making enzymes based on what enzymes are present in the food itself there must be some feedback system. You are stating, indirectly, that teh body has the capability to detect which enzymes are present in the food and thus do not have to be made and also can detect which enzymes are not present in food and which must be made.

Starting with the salivary glands what is the detection (receptors) responsible for detecting enzymes in food? Where are these receptors located? What chemical messenger system is utilized to tell the salivary glands to produce or not produce amylase or lysozyme?

Now in the stomach what receptors are utilized to detect which enzymes should be made or which should not be made? What is the chemical messenger that is used to transmit this information to the cells lining the stomach which produce the enzymes secreted into the stomach? There has to be some communication and recognition for the system to work as you outline.

The same applies for the pancrease. How does the body determine which enzymes the pancrease should or should not make? How does the body differentiate between the thousands of proteins contained in a food source...plant or animal and decide which ones are digestive enzymes and which ones should be broken down for nutrients? What is the energetic cost of detecting and providing the chemical messenger to the proper organ and cells to prevent a enzyme from being produced?

This feedback system is critical for the body to be able to function as you claim. I have no knowledge of such a receptor system or its chemical messengers....please enlighten me how this is supposed to work!! References always appreciated. Tweet
