Mediterranean (MED) diet is a rich source of polyphenols, which benefit adiposity by several mechanisms. We explored the effect of the green-MED diet, twice fortified in dietary polyphenols and lower in red/processed meat, on visceral adipose tissue (VAT).MethodsIn the 18-month Dietary Intervention Randomized Controlled Trial PoLyphenols UnproceSsed (DIRECT-PLUS) weight-loss trial, 294 participants were randomized to… Continue reading The effect of high-polyphenol Mediterranean diet on visceral adiposity: the DIRECT PLUS randomized controlled trial

Acute feeding with almonds compared to a carbohydrate-based snack improves appetite-regulating hormones with no effect on self-reported appetite sensations: a randomised controlled trial
Early satiety has been identified as one of the mechanisms that may explain the beneficial effects of nuts for reducing obesity. This study compared postprandial changes in appetite-regulating hormones and self-reported appetite ratings after consuming almonds (AL, 15% of energy requirement) or an isocaloric carbohydrate-rich snack bar (SB).MethodsThis is a sub-analysis of baseline assessments of… Continue reading Acute feeding with almonds compared to a carbohydrate-based snack improves appetite-regulating hormones with no effect on self-reported appetite sensations: a randomised controlled trial
Association between vitamin D supplementation and COVID-19 infection and mortality
Vitamin D deficiency has long been associated with reduced immune function that can lead to viral infection. Several studies have shown that Vitamin D deficiency is associated with increases the risk of infection with COVID-19. However, it is unknown if treatment with Vitamin D can reduce the associated risk of COVID-19 infection, which is the… Continue reading Association between vitamin D supplementation and COVID-19 infection and mortality
Effect of honey on cardiometabolic risk factors: a systematic review and meta-analysis
ContextExcess calories from free sugars are implicated in the epidemics of obesity and type 2 diabetes. Honey is a free sugar but is generally regarded as healthy.ObjectiveThe effect of honey on cardiometabolic risk factors was assessed via a systematic review and meta-analysis of controlled trials using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation)… Continue reading Effect of honey on cardiometabolic risk factors: a systematic review and meta-analysis
Association of Dietary Intake of Flavonols With Changes in Global Cognition and Several Cognitive Abilities
APOE-ɛ4, late life cognitive activity, physical activity, and smoking, total flavonol intake was associated with slower decline in global cognition β estimate=0.004 (95% CI=0.001, 0.006), episodic memory β=0.004 (95% CI: 0.002, 0.006), semantic memory β=0.003 (95% CI: 0.001, 0.007), perceptual speed β=0.003 (95% CI: 0.001, 0.004), and working memory β=0.003 (95% CI: 0.001, 0.005) and… Continue reading Association of Dietary Intake of Flavonols With Changes in Global Cognition and Several Cognitive Abilities
Low-Energy Dense Potato- and Bean-Based Diets Reduce Body Weight and Insulin Resistance: A Randomized, Feeding, Equivalence Trial
AbstractWe evaluated the effect of diets low in energy density (1 kcal/g) and high in either potatoes (Potato) or pulses (Bean) on blood glucose control in participants with insulin resistance. We hypothesized that the Potato and Bean diets would have equivalent effects. This was an 8-week randomized, parallel design, controlled feeding study comparing Potato and… Continue reading Low-Energy Dense Potato- and Bean-Based Diets Reduce Body Weight and Insulin Resistance: A Randomized, Feeding, Equivalence Trial
Dysregulated amino acid sensing drives colorectal cancer growth and metabolic reprogramming leading to chemoresistance
Background and AimsCRC is a devastating disease highly modulated by dietary nutrients. mTORC1 contributes to tumor growth and limits therapy responses. Growth factor signaling is a major mechanism of mTORC1 activation. However, compensatory pathways exist to sustain mTORC1 activity following therapies that target oncogenic growth factor signaling. Amino acids potently activate mTORC1 via amino acid… Continue reading Dysregulated amino acid sensing drives colorectal cancer growth and metabolic reprogramming leading to chemoresistance
Mono-(2-ethyl-5-hydroxyhexyl) phthalate promotes uterine leiomyoma cell survival through tryptophan-kynurenine-AHR pathway activation
Uterine leiomyomas (or fibroids) represent the most common tumor affecting up to 80% of reproductive-age women. Epidemiological studies consistently indicate a positive association between exposure to endocrine-disrupting phthalates and leiomyoma risk; however, the underlying mechanisms remain unclear. Here, we demonstrate that the ubiquitous environmental pollutant mono-(2-ethyl-5-hydroxyhexyl) phthalate [MEHHP, the major metabolite of di-(2-ethylhexyl) phthalate] promotes… Continue reading Mono-(2-ethyl-5-hydroxyhexyl) phthalate promotes uterine leiomyoma cell survival through tryptophan-kynurenine-AHR pathway activation
Effects of a Low-Carbohydrate Dietary Intervention on Hemoglobin A1cA Randomized Clinical Trial
Importance Low-carbohydrate diets decrease hemoglobin A1c (HbA1c) among patients with type 2 diabetes at least as much as low-fat diets. However, evidence on the effects of low-carbohydrate diets on HbA1c among individuals with HbA1c in the range of prediabetes to diabetes not treated by diabetes medications is limited.Objective To study the effect of a behavioral intervention promoting a low-carbohydrate diet… Continue reading Effects of a Low-Carbohydrate Dietary Intervention on Hemoglobin A1cA Randomized Clinical Trial
