Final takeaway

Rather than assuming less salt is always better, consider discussing your individual sodium needs with a healthcare provider based on your specific health profile — DiNicolantonio's arguments throughout this genuinely contested book challenge conventional low-sodium consensus, but this remains an area of genuine ongoing scientific debate warranting individualized, professionally-guided consideration rather than uncritical adoption of either conventional or contrarian dietary sodium guidance.
