In her recent article for NPR, April Fulton largely discusses avoiding processed foods but she also has a few interesting at-home suggestions. She discusses how folks can try and cut out salt altogether for three weeks and then slowly add it back in. This will recalibrate the taste buds, so a little salt will start to go a very long ways. She also mentions adding salt to the finished product instead of using it throughout the cooking process.
Other Helpful Tips:
• Use unsalted butter in baking to control the amount of salt in the final product.
• Get excited about spices, and start to rely on them instead of salt. Experiment with Hungarian paprika, garlic, and interesting ground peppers.
• Get acquainted with unsalted nuts for snacking, cooking, and baking. You'll start to appreciate their natural flavors more than just what they're seasoned with.
• Read labels on lunch meats and cheeses: there's often an incredible amount of unexpected sodium in these sandwich-ready products.
