Level 5 - mechanism / opinion, no new human data
Narrative review of mechanistic, animal, and human literature without systematic search methodology

What was done
The authors synthesized findings from recent studies examining how dietary patterns (high-fat and high-carbohydrate diets) and non-dietary exposures (food additives and antibiotics) alter gut microbiota, impair intestinal barrier function, and facilitate lipopolysaccharide translocation into the bloodstream across human and animal models.
What was found
The abstract reports no numerical findings, effect sizes, or quantitative metrics. It states qualitatively that high-fat and high-carbohydrate diets increased intestinal permeability, elevated systemic lipopolysaccharide levels, and induced gut dysbiosis, with food additives and antibiotics further exacerbating barrier disruption and microbial alterations.
Why it matters
This review outlines the mechanistic connections linking diet, additives, and antibiotics to metabolic endotoxemia and systemic low-grade inflammation. It highlights gut barrier integrity as a common pathway in the development of obesity, type 2 diabetes, and inflammatory bowel disease.
Limits
This is a narrative review without a systematic search protocol, predefined study inclusion criteria, or formal risk-of-bias assessment. Findings combine evidence from animal models and human studies without distinguishing their relative contributions, and no sample sizes or quantitative results are provided in the abstract.
