Walnut Consumption Alters the Gastrointestinal Microbiota, Microbially Derived Secondary Bile Acids, and Health Markers in Healthy Adults: A Randomized Controlled Trial.

Background: Epidemiologic data suggest that diets rich in nuts have beneficial health effects, including reducing total and cause-specific mortality from cancer and heart disease. Although there is accumulating preclinical evidence that walnuts beneficially affect the gastrointestinal microbiota and gut and metabolic health, these relations have not been investigated in humans. Objective: We aimed to assess […]

Effect of short term hazelnut consumption on DNA damage and oxidized-LDL in children and adolescents with primary hyperlipidemia: a randomised controlled trial.

Children with primary hyperlipidemia are prone to develop premature atherosclerosis, possibly associated with increased oxidative stress. Nutritional therapy is the primary strategy in the treatment of hyperlipidemia and associated conditions. Dietary interventions with bioactive-rich foods, such as nuts, may contribute to the modulation of both lipid profile and the oxidative/antioxidant status. Our study aimed to […]

Better diet quality relates to larger brain tissue volumes: The Rotterdam Study.

OBJECTIVE: To investigate the relation of diet quality with structural brain tissue volumes and focal vascular lesions in a dementia-free population. METHODS: From the population-based Rotterdam Study, 4,447 participants underwent dietary assessment and brain MRI scanning between 2005 and 2015. We excluded participants with an implausible energy intake, prevalent dementia, or cortical infarcts, leaving 4,213 […]

Metabolic influence of walnut phenolic extract on mitochondria in a colon cancer stem cell model.

PURPOSE: Walnut phenolic extract (WPE) reduces proliferation and enhances differentiation of colon cancer stem cells (CSCs). The present study investigated the metabolic influence of WPE on the mitochondrial function of colon CSCs to determine its underlying mechanism. METHODS: CD133+CD44+ HCT116 colon cancer cells were selected by fluorescence-activated cell sorting and were treated with or without […]

Nuts and Cardiovascular Disease.

There is compelling evidence showing that nut intake confers protection against cardiovascular disease (CVD). We conducted a review of the literature with respect to observational studies and randomized trials completed in the past ≈25 years that examined nut intake and CVD endpoints. We included findings from major cohort studies, a large intervention trial, and numerous […]
