In order for us to have a healthy body and healthy nervous system, we must take certain minerals on a regular basis. Having a good, balanced diet will help in that, so the body can function optimally. Minerals like iodine and iron are essential for proper mental development and we must make sure that we get enough of them.
Lack of iodine can lead to a mental impairment and is one of the major causes of cretinism in infants. That is why usually table salt is getting enriched with iodine, so these cases of cretinism would be decreased and prevented. If you have a high blood pressure and do not use table salt, then you must make sure that you eat a lot of fish and other seafood which is rich with iodine. Iodine can also be taken through consummation of green vegetables or by tablets.
Iron is another mineral essential for our health. It produces the substance called hemoglobin, which is a pigment found in our red blood cells. Hemoglobin transports the oxygen we inhale throughout the whole body. Lack of iron in your body can lead to anemia. Anemia is a serious problem associated with lack of proper psychomotor functioning and cognitive problems. If you often feel tired, irritable, forgetful or nervous, it is advisable to visit a doctor and make a blood test through which you will see whether you need more iron in your body.
Iron can be obtained through many food sources such as beef, pork, fish, egg yolk, spinach, cereals and dried fruits. Sometimes lack of iron can be treated by taking various iron supplements or taking injections. Important thing to pay attention on is that iron supplements often need to be taken for longer periods of time in order to fully restore the missing iron reserves in the human body.
