While living on the International Space Station (ISS), astronauts are assessed to make sure they are receiving adequate nutrition. This is done through blood samples, food frequency questionnaires, comparing body mass before and after flight, using a food intake app, as well as an evaluation of any physical symptoms of nutrient deficiencies.

On the ISS, the food intake app allows astronauts to record their food intake by taking photos of the items, selecting the items on the interface, or creating an audio file where they describe the items consumed.

If an astronaut is not consuming enough calories or is becoming deficient in certain nutrients, their doctor will discuss options with them and get them back on track.

The food items available on the ISS are in single-serving packages; therefore, astronauts have to select multiples of the same package or mix-and-match with other items to create a fulfilling and balanced meal. For example, an astronaut could choose a package of rehydratable chicken and pair it with packages of spinach and rice.

On Earth, writing down the foods you eat can help you learn about your eating habits and determine if you are following the Canada's Food Guide recommendations. Additionally, comparing your plate to the Canada's Food Guide's plate is an effective way to see if you are consuming the recommended proportions of grains, protein, and vegetables and fruits.
