Antioxidants and Immunity:

Antioxidants like catalase and peroxidase depend heavily on iron to work effectively against free radicals. Iron also affects cytokine production in cells, lymphocyte cytokines which are an important part of the immune system.


Lack of iron makes cells resistant to insulin and prevents the conversion of blood sugar to energy. High insulin along with lack of blood sugar conversion both contribute to heart disease, type-2 diabetes and obesity risk.
