It depends-a healthy snack can come in many different forms. think of snacks as a way to keep your hunger from taking over between meals, sustain your energy throughout the day and sneak in nutrients (think fibre, protein, calcium and iron) that you might not be fitting into meals. when choosing snacks, choose the option that works with your lifestyle, and be flexible. some days, a homemade whole-food snack will work, some days a good quality protein bar eaten on the go is your only option. think outside of the box and use the criteria mentioned in questions 1 and 2 to make the best choice.
