Nutrition in Disguise: Development and Palatability Testing of Novel Food Products

Study Overview
=================
Brief Summary
-----------------
Nutrition in Disguise is focused on developing and testing the acceptability of nutrient dense food products appropriate for older adults and specifically those living in long term care.

Detailed Description
-----------------
Project Description: The overall goal of this research is to develop food recipes that are rich in vitamins, minerals and other food components known to support the physical and mental health of older adults. A variety of enhanced food recipes will be initially designed for older adults living in residences with applicability to pre-frail and frail older adults living in the community. It is hypothesized that the nutrient (protein and vitamins and minerals) density and anti-oxidant (i.e. phytochemical) potential of menus used in residential environments can be improved in a cost-effective manner with the inclusion of several enhanced food recipes designed for this population. This will be achieved by identifying high nutrient ingredients that can be incorporated into recipes of foods that are highly consumed by this segment. Initial work will summarize what is known from existing literature about micronutrient deficiencies and interventions with vitamins, minerals and antioxidants to improve the health of older adults. Foods commonly consumed that can be enhanced to promote their nutritional density (e.g. more nutrients in less calories) will be identified and recipes developed and tested with older adults living in the community and in residences. Products that pass this testing will then be introduced into a residence menu rotation to determine if they are well accepted by residents. A cost benefit of introducing these new products into a residence menu will be demonstrated by showing the gains in nutritional quality of the menu for the cost of producing these products in the home. Relevance to the field of food innovation: Currently, older adults, especially those who are frail or live in residences, do not consume adequate nutrition to optimize their health. Micronutrient inadequacies are a potential problem. Research to date suggests that diet can also be supportive for delaying frailty and slowing the progression of dementia. Yet, food choices and offerings can be low in nutrition. Cost effective, innovative recipes that used common ingredients to reach nutrition goals for older adults are needed. Anticipated outcomes: Up to 10 enhanced recipes that have been developed for residences will be developed and tested for palatability. Knowledge tools will be created for home chefs on how to incorporate nutrient dense ingredients into recipes and how to use the information gained in this project for menu planning.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Palatability Scale | Participants rate the palatability of the enhanced recipe sample using a five point scale (liked very much to disliked very much) with questions on flavour, texture, appearance, overall liking and ask if the participant woudl eat this product again | 19 months |
