Given these limitations, and to obtain consistent agreement within the studies appraised in future systematic reviews, one should consider investigating the entire Bacteroidetes and Firmicutes phyla and not only particular species. We found no significant changes in this gene in the small intestine and liver Supplementary Figure 14A and B. Today, more than ever before, it has become clear that obese children are prone to become obese adults, with higher chances of developing severe comorbidities, such as dyslipidemia, metabolic syndromes, cardiovascular diseases, and type 2 diabetes.
