Head home.</p> <p>That&rsquo;s the <strong>correct clinical judgment</strong>. But from the perspective of precision nutrition, 5.5% has already entered &ldquo;watch&rdquo; territory.</p> <h2 id="clinical-standards-versus-precision-nutrition-ideals">Clinical standards versus precision nutrition ideals</h2> <table> <thead> <tr> <th>Marker</th> <th>Clinical medicine</th> <th>Precision nutrition</th> </tr> </thead> <tbody> <tr> <td>HbA1c normal</td> <td>Under 5.7%</td> <td><strong>5.0–5.3%</strong></td> </tr> <tr> <td>HbA1c pre-diabetic</td> <td>5.7–6.4%</td> <td>Caution above 5.4%</td> </tr> <tr> <td>Fasting glucose normal</td> <td>Under 100 mg/dL</td> <td><strong>80–90 mg/dL</strong></td> </tr> </tbody> </table> <p>This gap stems from different <strong>measuring sticks</strong>.</p> <p>Clinical standards are designed to determine <strong>the presence or absence of disease</strong>.
