When our digestive ability is weak, we don’t get all of the nutrition contained in the foods we eat. This is because food, including proteins and minerals, must be fully broken down by stomach acid in order for our body to be able to use it.

In fact, poor digestion of protein is one of the largest causes of muscle loss as we age: our digestive system isn’t working as well as it was when we were younger, and so not enough protein is being broken down for our body to use.

But it’s not just our cells that need this nutrition.

Specific bacteria in our colon are responsible, in whole or in part, for the creation of the neurotransmitters serotonin and GABA, the happy, calming neurotransmitters.
