As a former nutritionist, of the independent research persuasion, I've always been a proponent of "live" foods in general - raw, naturally fermented, even raw animal products such as eggs, some fish (raw or marinated), raw dairy (where available) and some meats all from highest quality sources - organic, pastured, etc. Largely in the Weston Price tradition. I've shied away from many of the foods with higher microbial content in recent years, but am considering gradually adding in small amounts of naturally fermented veggies such as sauerkraut, like a probiotic supplement. My CFS research has focused mainly on Dr Chia's work and I haven't delved into the researchers who focus mainly on diet and the gut. So I'm wondering if there is a consensus about how a person with CFS who naturally has gut issues should generally approach foods and supplements that have a high microbial content, whether these should generally be used with caution if one hasn't gone through specific testing.
