OPTIC SYSTEM FOR PILATES
Vitamin A is essential in the formation of visual purple which illuminates objects in dim lighting.
The retina stores vitamin A within four optic pigments; the one used in dim lighting is termed rhodopsin, or visual purple.
The other three optic pigments are collectively termed iodopsins and are required for normal daylight vision.
Vitamin A is also required for peripheral or side vision and correct colour vision. A deficiency of vitamin A can lead to poor vision and cornea disorders, and a prolonged deficiency may cause blindness.
2. DIGESTIVE SYSTEM
Vitamin A is required for the secretion of gastric juices, which are required for protein digestion. Low-protein diets may restrict the effective use of vitamin A.
For people having difficulty in digesting fats, a deficiency of this vitamin may persist.
Alcohol consumption causes a loss of vitamin A via the liver.
Sweet potato and pumpkin are excellent sources of vitamin A carotene.
