Ten days to two weeks from the day you actually start the diet (depending on how your treatment has progressed at the time), you could test a natural probiotic, specifically homemade kefir or homemade yogurt – if you start one of these at that time, you should definitely use homemade products only and not a commercial type of yogurt or kefir.
Then two weeks later, or four weeks after finishing the detox, you can test commercially purchased organic non-sweetened Greek yogurt. Oikos and Fage are two excellent brands of organic Greek yogurt.
NOTE: Homemade kefir will be the most beneficial whole food supplement added throughout your treatment.
Regarding the kefir, can this be either milk or water kefir?
Also, I want to do this diet to the best of my ability (I will be starting Tuesday 17th April) but do i have to buy such expensive probiotic tablets? I really cant afford this. Is there any alternative?
