In a small cohort of MS patients, a high-vegetable/low-protein diet increased the abundance of fecal Lachnospiraceae that correlated with a decrease in IL-17+ CD4+ T cells and an increase in IL-10+CD14+ monocytes in the blood as well as a reduction in relapse rate compared to “western diet” MS patients (115). This evidence concerns the gene IL10 and myeloid sarcoma.
