I'm trying to find more information on the idea of taking a break from probiotics (kefir and other fermented foods/supplements) for several days each month. Have you heard of this before? Can we find any reputable information or even helpful anecdotal research on this? I remember reading in a few places a while ago that the Tibetans would take about 10 days off of milk kefir each month, to give the body a break and allow it to work for itself.
It makes sense that the probiotics (or anything) could stop working for us if the body gets used to them. I found that milk kefir helped me (with digestion and immunity) a lot for awhile, and then when I didn't take a break for months, I got pretty sick and felt I needed to go off it. I'm not sure if it's sufficient to rotate fermented foods, or just take everything sporadically, or if it's best to take a break from all probiotics for at least a few days per month. I like my daily milk kefir as a protein snack but want to know if I should take this break thing seriously.
The research on Kefir is that it is a transient bacteria so it needs to be a regular in the diet. Having said that I see no problem taking a break for up to 10 days. I would do it during a stable time where I am not traveling or coming into contact with new environments. Generally I let my body tell me. I find that every once in awhile I just stop and then after 3 – 10 days I miss it, so I start taking it again.
