Re: yogurt - In the book that really frames the diet, Breaking the Vicious Cycle, it's like the core food. Not that you eat a lot of it, but it's involved in a lot of recipes. Fermentation for 24 hrs as opposed to 8-12 (depending on taste preference for tartness) gets you a lot more beneficial bacteria. The intro diet according to BtVC is here. The intro diet according to the SCD Lifestyle site is mostly just the chicken soup w/ all veggies removed after cooking except carrots, which are supposed to be pureed before being added back in. I tried blending them, but that didn't work well, so I'm just mashing them now. From the base of this soup, you start adding in cooked fruits (apple or pear sauce), then you can start adding in pureed squash, then you go as you need to to test foods and see what sits okay with your digestion.
I'm not sure how the bacteria content in fermented veggies, kombucha, or water kefir compares to this yogurt, in terms of composition and quantity. I'll have to do some poking around for dairy-free SCD recommendations.
Re: C25k - Do you think it'd be better to run in the morning, when I wake up, or the evening, before or after dinner? I'm usually really hungry after work.
