High dietary glycemic load (GL) has been associated with an increased risk for chronic diseases, including type 2 diabetes, coronary heart disease, and selected cancers. The aim of this study was to identify the main food and food group contributors to dietary GL in a representative sample of US adults to inform future interventions. ⋯ In this US cohort of white and black adults, sweetened beverages were major contributors to GL overall, especially in black participants. This information may help to inform future interventions targeting reduction in dietary GL.

It has been suggested that a greater dairy consumption is a contributing factor to a lower prevalence of metabolic syndrome (MetS) as a result of the possible actions of some milk nutrients. However, results remain controversial. The aim of this study was to examine the association between dairy consumption and MetS and its components. ⋯ A greater dairy consumption is associated with a lower prevalence of MetS, with calcium probably being the nutrient responsible for this association.

Although intake of minerals has been suggested to be beneficial against depression, epidemiologic data from free-living settings are limited. The aim of this study was to determine the cross-sectional associations between the intake of magnesium, calcium, iron, and zinc and the prevalence of depressive symptoms in Japanese employees. ⋯ Results suggest that higher dietary intake of magnesium, calcium, iron, and zinc is associated with lower prevalence of depressive symptoms in Japanese employees.

An association between dietary acid load and cardiovascular disease risk has been reported in epidemiologic studies; however, there are no reports to our knowledge of this association in patients with diabetic nephropathy (DN). Therefore, the aim of this study was to examine the association between dietary acid load, based on potential renal acid load (PRAL) and protein:potassium ratio (Pro:K) scores, and cardiovascular disease risk factors in individuals with DN. ⋯ We found that both PRAL and Pro:K were positively related to HbA1c in the setting of DN, whereas other biochemical and kidney-related markers varied with PRAL and Pro:K status. Future studies are warranted to clarify the clinical outcomes of dietary acid load in older populations as well as in patients with chronic kidney disease.

Dietary diversity is recognized as a key indicator of dietary quality. However, its association with blood antioxidant levels has not been investigated. The aim of this study was to assess the association of the dietary diversity score (DDS) with blood antioxidant status in women who attend the sports clubs of a municipality in western Tehran, Iran. ⋯ DDS is associated with blood antioxidant markers. Increasing the dietary diversity might be associated with a reduction in oxidative stress.
