"Eat unprocessed foods to calibrate your salt needs Because salty and sweet taste pathways interact inside the brain, processed foods that combine both flavors make it nearly impossible to accurately sense how much salt you are actually consuming. Huberman recommends that anyone trying to optimize sodium intake do so "in the context of a fairly pure, meaning unprocessed, food intake background," adding that "the closer foods are to their basic form and taste, the more quickly you're going to be able to hone in on your specific salt appetite and salt needs." Switching predominantly to whole foods for even a few weeks gives the nervous system a clean baseline for tuning sodium intake to individual biology.
