You become sick repeatedly
When the body is faced with nutrient deficiencies, the immune system will be naturally weaker because they do not have the necessary ingredients to fight infections. Dr. Moore argues that red blood cells help carry oxygen to the spleen. Spleen is a key to fighting infections. If the body does not have enough iron, it can not stop infections. Red blood cells also carry oxygen to the lymph nodes, which includes white blood cells that fight infections. If you have iron deficiency, your body will not produce enough white blood cells, which will cause you to become ill.
