My nutrient analysis at NutritionData suggests that the un-supplemented Ketogenic Mediterranean Diet may be deficient in manganese. Here’s a summary of manganese physiology.
The role of manganese in human health is unclear. It is involve in detoxification of superoxide radicals and is found in several enzymes. Deficiency may cause a scaly dermatitis (skin rash) and lipid abnormalities. Deficiency is very unusual, but may be seen in highly restricted diets.
Despite decades of practing medicine, I’ve never seen a case of manganese deficiency. Maybe I’ve missed it. But I’ve never seen any physician in my circle of colleagues diagnose it either.
