Ginger has been proposed as an adjuvant treatment for chemotherapy-induced nausea and vomiting. ⋯ Ginger supplementation might benefit chemotherapy-induced vomiting as well as fatigue. Due to clinical heterogeneity, this systematic review update found no association between ginger and chemotherapy-induced nausea and other chemotherapy-induced nausea and vomiting-related outcomes. The results of this systematic review and meta-analysis provide a rationale for further research with stronger study designs, adequate sample sizes, standardized ginger products, and validated outcome measures to confirm efficacy of ginger supplementation and optimal dosing regimens.

We conducted a systematic review and dose-response meta-analysis of prospective studies to summarize findings on the associations between intakes of soy, soy isoflavones, and soy protein and risk of mortality from all causes, cancers, and cardiovascular diseases. ⋯ Soy and its isoflavones may favorably influence risk of mortality. In addition, soy protein intake was associated with a decreased risk in the mortality of breast cancer. Our findings may support the current recommendations to increase intake of soy for greater longevity.

Meta Analysis
The Associations of Fruit and Vegetable Intakes with Burden of Diseases: A Systematic Review of Meta-Analyses.
Low fruit and vegetable intakes are recognized risk factors for noncommunicable diseases. This systematic review summarizes published meta-analyses of global burden of diseases attributable to low fruit and vegetable intakes, and the best relative risk estimates. ⋯ This systematic review supports existing recommendations for fruit and vegetable intakes. Current comparative risk assessments might significantly underestimate the protective associations of fruit and vegetable intakes.

Sugar-sweetened beverage (SSB) consumption among children and adolescents is a determinant of childhood obesity. Many programs to reduce consumption across the socioecological model report significant positive results; however, the generalizability of the results, including whether reporting differences exist among socioecological strategy levels, is unknown. This systematic review aimed to examine the extent to which studies reported internal and external validity indicators defined by the reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) model and assess reporting differences by socioecological level: Intrapersonal/interpersonal (Level 1), environmental/policy (Level 2), and multilevel (Combined Level). ⋯ Adoption, implementation, and maintenance reporting did not vary among levels. Interventions to reduce SSB consumption in children and adolescents across the socioecological spectrum do not provide the necessary information for dissemination and implementation in community nutrition settings. Future interventions should address both internal and external validity to maximize population influence.
