A Breakdown of Macronutrients: Protein

Protein is a building block for healthy cells in the body and an important nutrient to get enough of during cancer treatment and recovery. That’s because protein helps with healing after treatment and keeps your immune system strong.

Protein rich foods include fish, poultry, eggs, and dairy products along with plant-based options like beans, lentils, nuts, seeds, soy foods and dairy alternatives.

The chart below shows the average amount of protein in a serving of various foods. Your Iris Registered Dietitian and Licensed Nutritionist can help you determine how much protein you need daily.

Aim to spread your protein intake throughout the day. This helps your body to absorb and use protein in the most efficient way. Here’s an example of how you can eat protein at each meal/snack in a day:

  • Breakfast: Steel-cut oatmeal, eggs, or peanut butter toast for breakfast

  • Lunch: Tuna sandwich or lentil soup

  • Snack: Plain Greek yogurt with fruit and nuts

  • Dinner: Baked fish, chicken or tofu with vegetables and a whole grain.

If it is difficult to eat protein rich foods try making a homemade smoothie that includes ½ to 1 scoop of protein powder. For recipe ideas, see Supplementing with Smoothies During cancer care.
