We performed a systematic review to summarize the available data focusing on overall maternal dietary intake rather than single foods and nutrients. Searches included PubMed, OVID Medline, Web of Science, and Embase up to November 28, 2024. Searches were not restricted by geographical location and included studies published in English only. The ROBINS\u2010I Cochrane tool was used to assess risk of bias. Meta\u2010analysis was conducted when \u22652 studies examined the same dietary pattern\u2010outcome\u2010age combination; a fixed\u2010 or random\u2010effects model was used based on\n                    <jats:italic>I<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    . When studies reported multiple effect sizes, a multilevel meta\u2010analysis accounted for within\u2010study clustering. We included 28 papers reporting on 29 diet patterns, indices, or diversity. Diet patterns included healthy and unhealthy diet patterns, healthy and unhealthy diet indices, and healthy and unhealthy diet diversity. Allergy outcomes were atopic dermatitis\/eczema, food allergy, allergic rhinitis, asthma, and allergic sensitization\/atopy. Only diet diversity during pregnancy showed a modest protective effect against food allergy (OR\u2009=\u20090.95 (0.92\u20130.99)). A pro\u2010inflammatory diet was linked to increased asthma\/wheeze risk in children under 5 (OR\u2009=\u20091.17 (1.04, 1.33)) and (OR\u2009=\u20091.18 (1.04, 1.34)) with high heterogeneity across studies. Modest evidence supports a protective role of diet diversity against food allergy and that pro\u2010inflammatory diets may increase early asthma risk in children. The Maternal diet index is the only index significantly associated with multiple allergy outcomes, and further studies in other cohorts are required.\n
