March is Nutrition Month – drawing attention to the connection between food and health. Eating sustainably is an important connection to health

What does it mean to eat sustainably?

The Food and Agriculture Organization of the United Nations offers the following definition1

Sustainable diets are those diets with low environmental impacts that contribute to food and nutrition security and to healthy life for present and future generations. Sustainable diets support biodiversity and ecosystems while also respecting culture, accessibility, affordability, nutritional adequacy, and safety to support human health. 

Here are 6 tips to help eat more sustainably:

1. Eat more plants and less meat

Compared to animal-based foods, plant-based foods require less land, energy and water to produce.2 Eating plant-based foods represents a way to eat more sustainably and have the added benefit of being healthy sources of protein, vitamins, minerals, and fibre – not to mention being easier on your wallet.

2. Purchase foods with minimal packaging

Conventional food production that uses typical packaging and distribution has been tied to an environmental burden.3 By purchasing foods with minimal packaging you reduce the stress on waste management services and manufacturers may be influenced to change their practices to address consumer preferences.

3. Buy foods in season and shop locally when possible

The distance food is transported is hard on the environment – fuel and food maintenance costs during transportation take a toll on the environment.3 It is less resource-intensive to produce foods during their natural growing season, and when you buy locally, you support the economic sustainability of your local community.

4. Waste less food

When we throw away food, we are throwing away natural resources and money.1 Consider decreasing food waste by:

i) Planning meals and incorporating any foods you already have in the fridge and pantry to reduce waste.
ii) Using frozen foods more often. One of the benefits of frozen foods is that you can use just as much as you need for a recipe.
ii) Use leftovers to create new meals and reduce waste.

5. Drink tap water

Drinking tap water, when the tap water is safe to drink, instead of bottled is an easy way to make an environmentally friendly choice. This reduces single-use plastic and minimizes emissions used to transport heavy bottled liquids.4

6. Grow your own food

Growing your own food is a great way to learn about food and sustainability.2 Kids love to help in the garden and watch how food grows.

Global Citizenship

Eating more sustainably is a responsibility for citizens of our plant and there are steps you can take today. By eating more plant-based, choosing foods with minimal packaging, buying local food in season, reducing food waste, drinking tap water, and starting a small garden, you can be on your way to eating more sustainably.

Sustainable eating is a commitment to human health for today and for generations to come.
