&gt; spinach has more other nutrients per calorie<p>Erm .. so? One can&#x27;t survive on spinach alone, so I don&#x27;t see this as a reason not to eat potatoes, or other starches.<p>&gt; im not going to turn potato into muscle, i will turn chicken into muscle.<p>Well, why not? Every single whole plant food has a complete amino acid profile and sufficient protein (5-10% of calories).
