Intake of Watermelon and Watermelon Byproducts in Male Mice Fed a Western-Style Obesogenic Diet Alters Hepatic Gene Expression Patterns, as Determined by RNA Sequencing.

Background: Consumption of watermelon has been associated with beneficial effects on metabolism, including reductions in systolic blood pressure, improved fasting blood glucose levels, and changes in hepatic metabolite accumulation.

Objectives: In the present study, we investigated the impact of consumption of watermelon flesh (WF), watermelon rind (WR), and watermelon skin (WS) on hepatic gene expression patterns in an obesogenic mouse model.

Methods: Hepatic RNA was isolated and RNA sequencing was performed following a 10-week feeding trial during which C57BL/6 J mice were provided either a low-fat diet (LF), high-fat diet (HF; controls), or HF plus either WS, WR, or WF.

Intake of Watermelon or Its Byproducts Alters Glucose Metabolism, the Microbiome, and Hepatic Proinflammatory Metabolites in High-Fat-Fed Male C57BL/6 J Mice.

Background: Watermelon intake has demonstrated effects on blood pressure regulation along with other health benefits.

Objective: We hypothesized that intake of whole watermelon and products made from watermelon rind (WR) and watermelon skin (WS) would remediate metabolic complications in C57BL/6 J male mice fed a diet modeling a Western-style diet.

Methods: Ten-week-old male C57BL/6 J mice were provided either a low-fat (LF) diet [10% fat (by energy), 8% sucrose (by energy) and no added cholesterol], a high-fat (HF) diet [45% fat (by energy), 20% kcal sucrose (by energy), and 1% (w/w) cholesterol], or an HF diet plus WS, WR, or watermelon flesh (WF) for 10 wk.

Taste Detection Thresholds of Resveratrol.

Resveratrol is a polyphenol that is associated with numerous health benefits related to heart disease, cancer, diabetes, and neurological function. The addition of this compound to food products would help to deliver these health benefits to the consumer. However, bitterness associated with resveratrol may impart negative sensory qualities on the food products into which resveratrol is added; thus, decreasing consumer acceptability.
