Raw vs. Cooked: Maximizing Nutrient Absorption

Understanding is spinach good for you raw or cooked depends on which nutrients you want to prioritize. Cooking spinach increases the bioavailability of certain nutrients while reducing others:

  • Vitamin K and calcium become more absorbable when cooked
  • Vitamin C decreases with cooking
  • Beta-carotene absorption increases by up to 500% when cooked
  • Oxalates (which can bind minerals) decrease with cooking

For optimal benefits, vary your preparation methods—add raw spinach to smoothies for vitamin C, and cook it with healthy fats like olive oil to boost absorption of fat-soluble vitamins.
