Physiological studies of whey protein in older people, with a focus on feeding behaviour, nutrition, obesity, type 2 diabetes mellitus and post-prandial blood pressure

description: Australia’s population is ageing. Health problems are more prevalent in elderly than younger people, and lead to much of the health expenditure and health resource allocation in this and other countries. Nutritional problems are common in the elderly and often contribute to the development and worsening of health problems in older people. A particular problem is the interacting effects of under-nutrition, reduced dietary protein intake, anabolic resistance to dietary protein (the need for greater intakes to produce the same benefits, particular on muscle mass and function) and consequent muscle loss, reduced function, and in some cases the development of sarcopaenia. Both type 2 diabetes (T2D) and obesity are prevalent in older people – and often coexist. Dietary measures are key to the management of both conditions, in older as in younger adults. Protein supplements either alone or in combination with other macronutrients are increasingly recommended to, and used by, older people, to prevent and/or manage these problems. Whey protein is often used alone or as part of these supplements, as it is has particularly beneficial effects on muscle anabolism. There remain gaps in our knowledge of the effects of whey protein ingestion in older people. This thesis comprises clinical studies designed to fill some of those gaps. The studies in this thesis from five clinical trials involved assessing responses to oral whey protein ingestion particularly whey protein concentrate on feeding behaviour, nutrition, obesity, T2D and blood pressure (BP) in older and younger people with a focus on older people. Dietary protein supplementation may play a role in the management of these conditions. The principal outcomes assessed were appetite; food intake; gut hormone release; gastric emptying rate; circulating glucose, glucagon and insulin concentrations; BP and heart rate (HR). Chapter 1: Introduction focusses on rising burden of ageing in Australia and other developed countries; nutri…
