Vegetable noodles, also called "voodles," are full of brain-healthy phytonutrients, fiber, vitamins, and minerals. In this dish, you'll use sweet potatoes noodles. These tubers are loaded with vitamin C and vitamin A (or beta-carotene), an antioxidant that gives them their bright orange color and helps boost brain health.

You'll get a good dose of the B-vitamin, folate, from the sweet potatoes and tomato sauce in this dish. Folate has shown to be particularly protective for cognitive health and fending off dementia. The tomato sauce also provides lycopene—an important antioxidant.


  • 1 medium sweet potato, peeled, washed and cut into 2 or 3 pieces
  • 1 tablespoon extra-virgin olive oil
  • 1 clove fresh garlic, minced
  • 1-15 ounce can pureed tomatoes
  • 1 teaspoon dried oregano
  • 1 teaspoon cinnamon
  • 1 teaspoon red pepper flakes
  • Dash of salt and black pepper
  • 1/8 cup fresh Parmesan cheese, grated


  1. Preheat oven to 350F.

  2. Spiralize each of the sweet potato pieces and put in a bowl to the side.  

  3. On the stovetop over medium heat, add olive oil and garlic; heat for a minute.  Pour in the pureed tomatoes.  Stir and add the oregano, cinnamon, red pepper flakes, salt, and pepper.   Stir well and allow to heat through.  

  4. Pour marinara over sweet potato spirals and mix until well-coated.  Spoon it into an oven-safe dish and bake for 30-45 minutes or until the sweet potato is cooked to a soft texture. 

  5. Remove from oven. Sprinkle with cheese and serve immediately.
