Special advice for the elderly.
They will need gradual introduction of whole foods
They might need digestive enzyme support. (Ox bile, pepsin, probiotics, fermented food)
They need much less food than you think.
I'm saying, give this a try for a few weeks. See if you and your loved ones get healthier. Even by a little bit. If it works, stick to it. If it doesn't, go back to your old ways.
