Vitamin A

Vitamin A is a fat soluble vitamin. Providing humans with healthy vision, bone growth, reproduction, immune system regulation, cell division and differentiation (which sends cells to our muscles, lungs, blood and brain) and with the prevention of diseases in the production of white blood cells. Vitamin A also promotes the healthy surface of the lining of the eyes, the urinary, respiratory and intestinal tracts, as well as helping skin and mucous membranes create a barrier against bacteria.

Vitamin A is a popular vitamin and can be found in many sources, including liver (of beef, pork, chicken, turkey and fish), carrots, broccoli leaves, sweet potatoes, kale, butter, spinach, leafy vegetables, pumpkin, collard greens, cantaloupe melon, eggs, apricots, papaya, mango, peas, broccoli and winter squash.

Considering the extensive list of Vitamin A sources it might surprise you to hear that Vitamin A deficiency is quite common, mainly in developing nations.

Increased predisposition towards Blindness - If you don't have enough Vitamin A in your diet, you have an increased predisposition towards blindness. Between 250,000 and 500,000 children in developing nations become blind from Vitamin A deficiency. Deficiency can also cause night blindness.

Increased predisposition towards cancer - A lack of Vitamin A in your diet can lead to you having a higher risk of contracting cancer especially in the lungs, head, neck and breast.

Effects on the immune system - Research has shown that a deficiency of vitamin A can leave you more susceptible to skin and respiratory infections.

Effects on cells - A deficiency of Vitamin A can lead to abnormal cell growth. This can lead to growth retardation and abnormal skin growth.

Vitamin A is fat-soluble, which means the excess amounts are harder to dispose of than water-soluble vitamins. Which means that if you intake too much Vitamin A toxicity can occur. Vitamin A toxicity can result in nausea, jaundice, irritability, loss of appetite, blurry vision, muscle pain, abdominal pain, weakness, headaches and an altered mental status.
