The etiology of uninvestigated reflux is largely unknown. Although diet has been associated with uninvestigated reflux, the role of dietary patterns is not clear yet. The aim of this study was to investigate dietary patterns in relation to uninvestigated reflux among Iranian adults. ⋯ Although the present study showed no statistically significant associations between major dietary patterns and the risk for uninvestigated reflux, relative positive associations were found between uninvestigated reflux and adherence to either fast food or traditional dietary patterns, suggesting that these contribute to the risk for developing reflux.

Randomized Controlled Trial
Effects of Rubus occidentalis extract on blood pressure in patients with prehypertension: Randomized, double-blinded, placebo-controlled clinical trial.
Black raspberry (Rubus occidentalis) is known for improving vascular function. However, there has been no study evaluating its effects on 24-h systolic and diastolic blood pressure in prehypertensive patients. The aim of this study was to examine those effects. ⋯ The use of black raspberry significantly lowered 24-h BP in prehypertensive patients during the 8-wk follow-up. Black raspberry used as a dietary supplement could be beneficial in reducing SBP in prehypertensive patients.

To systematically review the published evidence regarding the association between Mg intake and serum concentrations with MetS and, if possible, to summarize the results using a meta-analysis. ⋯ The present systematic review and meta-analysis found an inverse association between Mg intake and MetS. However, the inverse association for serum Mg levels was highly heterogeneous and sensitive. The link between Mg status and MetS should be confirmed by prospective cohort studies controlling the association for other nutrients related to MetS risk.
