Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess whether it is possible to carry out a research project with a nutritional intervention in senior's residence. Life in a small community is very different and above all unique, which could be an asset in a research setting.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To ensure its functioning, the brain needs a lot of energy. However, during aging, it has difficulty properly using its main fuel, sugar. The brain then becomes "starved". This energy deficit is part of the vicious circle leading to memory problems. The brain, like a hybrid car, can run on two fuels, sugar and ketones. Providing alternative fuel to the brain, in the form of ketones, and thus offsetting the energy it needs, could improve its functioning and help prevent or improve memory problems.

There are several ways to increase ketones in our body such as certain dietary oils, natural health products, physical activity or certain diets. Reducing the amount of sugar in our diet is also a strategy that can increase ketones. A low-sugar diet is already widely used in the prevention of several important diseases, including type 2 diabetes and even Alzheimer's disease.

This study will assess the feasibility of a community intervention project in a seniors' residence with the eventual overall objective of slowing the progression or onset of AD and related health indicators, through a dietary modification.

This feasibility study will last 6 months. The basic characteristics of interested participants will be collected. The global spheres of evaluation are the following: metabolic profile, cognition, quality of life and nutritional status. Glucose measurements will be taken continuously via a sensor over two weeks during the project.
