What happens if we don’t get enough?
You will wonder why we need to eat all these. What’s the need of this Vitamin? Once you read through the importance of the Vitamin A, you will realize how crucial it is for our body & what its deficiency can do? Vitamin A plays a role in a variety of functions throughout the body, such as:
- Vision – It can’t improve your distance vision or help you see more clearly, but a deficiency can certainly harm your vision in several ways. One form of vitamin A in your body, retinal, helps nerves transmit the image of what you see to your brain. When you are in a dark situation (such as driving at night) and light flashes (such as oncoming headlights), certain compounds in the visual cycle are bleached out and need to be refreshed by having a good supply of retinal available. If a person is deficient in vitamin A it takes much longer for their eyes to adjust to be able to see again. Another way vitamin A helps your vision is by maintaining the moisture of your mucous membranes.
The deficiency of the Vitamin A can cause blindness in the eyes, the hardness in the lungs are not able to fight infections whereas the damage to the intestine & stomach causes severe digestive problems. The deficiency can prove fatal.
What happens if we exceed the dose?
Just as deficiency is dangerous for the body, too much is not too good also. Being vegetarian secures you from exceeding the dose of Vitamin A, because the body has control to converts Vit A from beta carotene as required. But have caution while having non veg , specially read meat and liver, cause having them excessively might cause overdose.
