Very interesting. I'm 45 and recently became chronically constipated. I determined that I had somehow killed off my gut bacteria and began a treatment of eating nothing but cruciferous salads each day, supplementing with probiotics (with as many bacterial strains as I could get). I was eating yogurts regularly, but none of those contained enough bacterial variety (you need many more strains to maintain health).

This restored me to perfect function and taught me that my gut microbiome was fucked up for years, even decades.

I cannot believe how good I feel and how perfectly my digestive system functions now. When the constipation hit I thought I was literally dying. Even a 100% raw vegetable diet was not digesting properly and would takes days to exit at first. Any carbs or bread at all would jam me up completely.

I have been maintaining perfect gut function since then by avoiding alcohol and eating a wide range of raw vegetables and cruciferous salads to feed the bacteria. However, I'm able to digest anything now, effortlessly. Remarkable.
