The Relationship Between Nutrition and Dementia

Health Eating for Seniors  |  January 15, 2026

We begin the year with January, Alzheimer’s Awareness Month in Canada, which is why we want to do our bit to help improve the quality of life of people with dementia in Canada.

For anyone caring for a family member with dementia, it is important to keep in mind that nutrition is much more than just food; eating should have a purpose beyond satisfying hunger. 

Proper nutrition is a powerful tool that preserves cognitive function, stabilizes mood, and improves quality of life. When you face the daily challenges of home care for seniors, knowing which foods to prioritize and how to serve them can make a tangible difference. At Comfort Keepers Ottawa & Kanata, we understand that feeding a loved one with dementia goes beyond calories; it’s about providing nutrients, facilitating the experience, and reducing stress in the daily routine.

Why is nutrition a fundamental pillar of dementia care?

There is a famous saying that goes, “You are what you eat,” and research proves it: what we eat directly affects our brain health. For a person with Alzheimer’s, a proper diet can help:

Slow the progression of cognitive decline.

• Improve energy levels and stabilize mood, reducing agitation or apathy.
• Strengthen the immune system, which is crucial for preventing common infections.
• Prevent muscle loss (sarcopenia) or weight gain, maintaining a healthy muscle-to-fat ratio.

As a family caregiver, you already carry a huge responsibility in all aspects of life. Our goal with this guide is to ease some of that burden by providing you with clear, practical, evidence-based information so that mealtime is a moment of connection and well-being, not stress.

Key Nutrients for Proper Brain Function: What to Look For and Where to Find Them

These are the essential components to consider including in the diet, according to leading organizations such as the Alzheimer’s Society of Canada.

1. Antioxidants

As their name suggests, antioxidants combat oxidative stress. One of the main characteristics of brains with dementia is that they are particularly vulnerable to cellular damage, and antioxidants play an important role in combating this.

Foods with the most antioxidants include berries (blueberries, strawberries, raspberries), dark green leafy vegetables such as spinach, and other foods such as nuts, cocoa, and beans.

2. Omega-3 fatty acids

Omega-3 is essential for preserving neurons and reducing brain inflammation, as well as slowing cognitive decline.

One of the best sources of omega-3 is fatty fish (salmon, mackerel, sardines). It is also found in ground flaxseed, chia seeds, and walnuts.

Omega-3 supplements are also available, but you should only take them if they have been prescribed by your trusted doctor.

3. B vitamins (especially B12, B6, and folate)

These are critical for reducing levels of homocysteine, an amino acid linked to the risk of cognitive decline and cardiovascular disease.

They can be found in foods commonly found in the Canadian diet, such as eggs, chicken, legumes, asparagus, cereals, and bananas.

Simple Strategies for Overcoming Common Feeding Challenges for Seniors with Dementia

We know that theory and reality are often different. Here are some challenges we frequently encounter at Comfort Keepers Ottawa, along with our suggestions:

Case 1: “Loses interest in eating or forgets that they have eaten.”

This is very common. We recommend establishing strict routines with set schedules. Offer “mini-meals” or nutritious snacks every 2-3 hours (a handful of nuts, a piece of cheese, half a smoothie) instead of three large meals. Keep food in plain sight as a visual reminder.

Case 2: “Has difficulty chewing or swallowing (dysphagia).”

It is important not to force them to eat something that is difficult for them; instead, modify the texture without sacrificing nutrition. Thick, nutritious purées (such as lentil soup with spinach) are ideal. Thicken liquids if necessary. At Comfort Keepers Ottawa & Kanata, our caregivers are trained in safe feeding techniques and in identifying signs of choking.

Case 3: “They forget how to use cutlery or become agitated during meals.”

Simplify the process as much as possible. Use a single plate with compartments, adapted cutlery with thick handles, and straws for liquids. Serve one food at a time to reduce overstimulation. Stay calm and patient; mealtimes should be peaceful.
