Your lower incidence of getting ill could be due to better absorption of Vitamin C. Vitamin C and glucose have similar molecular structures. Insulin moves BOTH glucose and ascorbic acid into cells. Due to their structure similarities, sugar molecules and glucose molecules are in competition with each other to penetrate your cells. Both vitamin C and glucose enter cells using a critical protein known as the Glut-1 receptor. Naturally your Vitamin C levels would likely be higher if you are following a low carb diet.
In light of this competition, it follows that the higher your dietary carbohydrate (glucose) intake, the higher your vitamin c requirements. -Dr Nam Mburu
