Brief Summary:
Two of the most effective lifestyle-based approaches to reduce the risk of adverse health events and enhance quality of life with aging are exercise and a healthy diet. Currently, the Canadian recommended dietary allowance (RDA) for protein is 0.8 g/kg/day, however, several expert groups have advocated for a higher RDA of protein (~1.2 g/kg/day), along with more evenly distributed daily consumption, in older persons. Eggs are considered a nutrient-rich protein source but have recently been scrutinized. This study will compare a high-protein, egg-containing diet and a high-protein, non-egg diet in healthy older persons.

Condition or disease Intervention/treatment Phase
Aging Behavioral: Exercise Behavioral: Exercise plus diet (egg) Not Applicable

Detailed Description:
This study will examine the impacts of an egg-containing diet and a non-egg diet in healthy older persons. Briefly, participants (healthy persons, age 60-75 years old) will consume their normal diet or their normal diet plus 4 eggs completing a structured exercise program (designed to meet Canada's Physical Activity Guidelines) for a total of 12 weeks. Participants will be randomly assigned to the Egg or Control (non-egg) group. Before and after the 12-week intervention, participants' undergo assessments of diet-quality, muscle health, fitness, bone health, and vascular health.

    Handgrip strength

  3. Vascular health [ Time Frame: Pre- and post-intervention over 12 weeks ]
    Measures of arterial compliance

  4. Change in body fat mass [ Time Frame: Pre- and post-intervention over 12 weeks ]
