Meta-analysis or Systematic Review

Critically low

Examined relationship (observational studies) or effect (intervention studies) of vegetarian-based with a non-vegetarian-based control dietary patterns; outcomes included: CRP; studies conducted in human populations of all ages; observational based: could include cross-sectional, case-control, prospective cohort, retrospective cohort designs and adhered to a vegetarian-based diet for >/= 1 y; intervention based: could include RCT, non-RCTs, pre-post designs and follow a vegetarian-based diet for > 4 wk

Not published in English; conference abstracts, editorials, book series, errata, conference proceedings; did not complete between-group analysis or provide raw data to allow these to be calculated; animal or cellular models; Analyzing consumption of single foods or food groups rather than dietary patterns; used drugs that could alter biomarkers outcomes; Assessing antibodies to food antigens rather than disease or general blood-immunoglobulins; any type of meat allowed in the vegetarian-based groups (fish); examined a single diet component/supplement only; Intervention studies: used a lifestyle intervention with diet intervention; used intervention diets containing any type of meat; did not report to control/discourage meat intake

This systematic literature review aimed to determine if vegetarian-based eating patterns in humans are associated with or able to modulate, inflammation or immune biomarkers compared with those following non-vegetarian dietary patterns. A meta-analysis explored the effect of vegetarian-based eating patterns on common inflammation and immune biomarkers compared with non-vegetarian dietary patterns.
