Soaring in Space with Canada's Food Guide
Duration: 70 minutes
Canada's Food Guide recognizes that healthy eating is more than the foods you eat and involves:
- Being mindful of your eating habits
- Cooking more often
- Enjoying your food
- Eating meals with others
The guide also encourages making it a habit to eat a variety of healthy foods each day by:
Foods packaged or processed in the following ways are best for space flight:
- Eating plenty of vegetables and fruits, whole grain foods, and protein foods
- Making water your drink of choice
- Using food labels
- Limiting foods high in sodium, sugars, or saturated fats
- Being aware of food marketing
The guide shows how your plate could be divided to encourage healthy eating: half consists of vegetables and fruits, a quarter is whole grains, and the remaining quarter is protein.
Astronauts aboard the International Space Station (ISS) have three meals and one snack per day. They must consume between 1900 and 3200 calories depending on their height, weight, and specific needs. Astronauts can choose their foods for each meal and snack. With this in mind, astronauts need to plan or be mindful of the foods they consume during the day to make sure their diet is balanced and healthy.
Although astronauts have a hectic work schedule, occasionally they eat meals together and may swap foods from their home country. Crewmembers may celebrate holidays together by eating a traditional meal associated with that holiday. Even when there is no special occasion, eating as a group is a fun way to relax!
CSA astronauts are scheduled one hour for lunch, which includes preparation and clean- up time. For breakfast and dinner they have more flexibility, as these meals are outside their normal working hours.
Although many meals available on the ISS come pre-prepared in a rehydratable or retort package, astronauts can get creative with their meals and try to "
cook" something from scratch. A common creation is burritos. To do this, they use tortillas, condiments, and various food items. See below for David Saint-Jacques and one of his crewmates creating pizzas on the ISS.
Limiting sodium and processed foods while aboard the ISS is difficult. Foods which are high in sodium and are processed often have a long shelf life, which is desirable for ISS missions because the ISS does not have a food refrigerator or freezer. However, foods sent to the ISS must have as little sodium as possible while still keeping the food palatable and with a long shelf life.
Nutrition guidelines for astronauts are based on the nutrition guidelines for people living on Earth; however, due to the unique environment of space, it can be difficult to meet those guidelines all the time. Once they return to Earth, astronauts can also return to following the healthy eating guidelines for Canadians as described in Canada's Food Guide.
Participants shall navigate through Canada's Food GuideFootnote * and identify aspects of the guide which can be applied to them and to astronauts aboard the ISS. Afterwards, participants shall play a mix-and-match game to solidify their understanding.
|Introduction to lesson and CFG||5 minutes|
|Explanation of activities||5 minutes|
|Individual Canada's Food Guide activity||30 minutes|
|Group activity||30 minutes|
To familiarize the participants with Canada's Food Guide
By the end of the activity, participants will be able to
- Identify four main messages of Canada's Food Guide
- Create a healthy-eating goal based on Canada's Food Guide recommendations
- Identify two examples of how astronauts can meet Canada's Food Guide recommendations
- Internet access (laptops, tablets, etc.)
- Background information
- Activity 1 worksheet
- Activity 2 instructions and mix-and-match cards
Activity 1: Participants will work individually to complete the activity worksheet about Canada's Food Guide. Participants will need access to the Internet via laptop, tablet, or computer. After the allotted time or when the participants are finished, they can complete Activity 2.
Activity 2: In small groups, participants will use the knowledge gained from Activity 1 to correctly match descriptions and situations on the ISS with the corresponding Canada's Food Guide recommendation.
