Becca's Digestion Tip Number Three: Cook minimally to preserve nutrients.
Best ways to cook:
Sauté in heat-resistant vegetable oils (canola, sunflower, safflower, sesame, or peanut oil) at a low to medium temperature. Steam. Bake. Stir-fry quickly at high temperature (also in a heat-resistant vegetable oil).
Worst ways to cook:
High-fat deep fry (fat heated at high temperatures can mutate into trans-fats). Boil (water soluble vitamin can leech out of into the boiling water). Barbecue (carcinogenic molecules develop on the surface of the food). Microwave (some research suggests that microwaves can create carcinogenic molecules, but the heath effects of microwaves are not well known).
With that said, none of these methods are terrible in moderation. Try cooking food in a variety of waves for better nutrient retention and to give food different textures!
