Conditions
Summary
In a single-blind, randomised, placebo-controlled crossover manner, this study aims to assess the impact of a high-fat mixed meal containing a whey protein (WP)-enriched milk fat globule membrane (MFGM) powdered ingredient on markers of heart and brain health in the fed state among middle-to-older-aged, postmenopausal women living with overweight and at moderate risk for cardiovascular disease. Participants will attend two \~8 hour study visits, where they will consume a high-fat meal containing a WP-enriched MFGM powdered ingredient or a placebo WP-based powdered ingredient. Each visit will involve anthropometric measurements and periodic assessments of heart health, including blood pressure and blood vessel stiffness measurements, blood sample collections, as well as computer-based tests measuring mood and cognition (brain function) over a 6-hour postprandial period.

Interventions
Participants will consume a high-fat, mixed meal containing approximately 75 g of test fat (refined palm oil), supplemented with a whey protein-enriched milk fat globule membrane (providing \~5 g of milk polar lipids) powdered ingredient. The experimental and placebo meals will be isoenergetic and protein-matched, and will be administered in a randomised order, with a washout period of at least 21 days between sessions.
