Eating a simple, healthy diet can give you the energy your body needs as its healing, and may help relieve some aches and pains, bloating, or GI issues. Oatmeal is one of the simplest things to make, but you can get creative with different toppings each day.
Here is a recipe from Cookie and Kate that gives a great suggestion to toast your old-fashioned oats before cooking! I'd recommend selecting Bob's Red Mill Gluten-Free Rolled oats. Please note, that not all oatmeal is gluten-free, so look for those options especially if you have gluten allergies or have celiacs disease.
Also, consider using milk-alternatives like Oatmilk or Coconut Milk instead of regular milk.
And spice things up with rotating through a variety of toppings like:
cinnamon
a dash of maple syrup
seeds like flaxseed, hempseed, pumpkin seeds, sunflower seeds, chia seeds
mixed nuts like cashews, almonds, walnuts, pecans
berries like strawberries, blueberries, raspberries (frozen berries work great, too!)
sliced apples or bananas
yogurt or nut butters for extra protein
