Why Should We Even Care About Vitamin A?

Does the thought of having night blindness, called nyctalopia, scare you? Basically night blindness is having difficulty seeing when lights are low. I wouldn't want that and I'm sure you wouldn't either. We want to see! You also would not want this, having foamy patches on the conjunctiva of your eye. There is a fancy name for this condition called Bitot's Spots. In addition, there is another situation of the eye that would be uncomfortable to have, that would be having dry eyes. Can you prevent all this from happening? There is a good possibility you can.

Vitamin A deficiency can place you in any of the above conditions. In order to prevent yourself from being deficient in vitamin A, indulge in pre-formed vitamin A called beta carotene. Beta carotene is the precursor to vitamin A. Your eye health will be in tip top shape when you have an adequate daily intake of beta-carotene rich foods such as pumpkin (tis the season!), carrots, dark leafy greens, spinach, orange juice, sweet potatoes, and cantaloupe. The beta carotene will be better absorbed well in your body when you don't dip down too low in your fat intake. Without adequate fat, you won't be able to absorb vitamin A as well as the other fat soluble vitamins that our bodies need.

So as you are enjoying your pumpkin soup this season, just know that your eyes are thanking you, so that you can see the world clearly!
