Have vegetables and fruit at every meal; they’re loaded with vitamins, minerals and phytonutrients. Plus, they’re low in calories and help you feel full because of their water and fibre content. Here’s another way to think about the power of produce: vegetables elbow out the more calorie-laden foods that tend to crowd your plate. If you pile on the veggies, you won’t have room for pasta. Think you’ll be sad missing out on mac ’n’ cheese? Maybe not: People in an Australian study who increased their fruit and vegetable intake reported improvements in overall life satisfaction. Shoot for two fist-size portions of produce at each meal, St. Pierre says.
