As one of the wealthiest nations in the world, it seems odd to worry about vitamin deficiencies in America. And yet, because we eat a diet so filled with processed foods, Americans often don’t ingest enough of the right kinds of vitamins and minerals.
Vitamin A is important for proper growth and development of our bodies. Vitamin A serves us in the manufacturing and activity of adrenal and thyroid hormones, nerve cell maintenance, immune function, cell growth, and maintaining skin health. In addition, Vitamin A is vital to our ocular health. There are four types of Vitamin A compounds in the human retina, and a deficiency can be one reason behind night blindness.
In addition to problems like night blindness and dry eyes, a vitamin A deficiency can also lead to dry hair, skin, and nails. We could have a problem with mucous membranes in our GI and respiratory tracts. Insomnia, fatigue, and the ability to get pregnant are all related to vitamin A deficiency.
There are two ways for us to get adequate vitamin A in our diet. By eating foods high in vitamin A like liver, kidneys, butter, and whole milk. Or, we can eat foods high in pro-vitamin A that our bodies then turn into vitamin A, like kale, spinach, collards, carrots, yams, squash and sweet potatoes.
