through my journal for the foods high in Vitamin A and a measurement converter. The nutrition tracker is frequently stating that I am over for Vitamin A. At first I let it go, but it stuck in the back of my mind as Vitamin A is fat-soluable, it stores up in the body. Further examination in the SP Reference Guide for Vitamins states:
"Because vitamin A is stored in the body, large quantities can be very harmful. Symptoms of overdosing include headaches, dry scaly skin, liver damage, bone and joint pain, vomiting, appetite loss, nerve damage, and birth defects. The Tolerable Upper Intake Level for vitamin A is 3,000 micrograms for adult males and females...
Your body can get vitamin A in two forms: retinols and beta-carotene. Retinols are found in foods that come from animals such as meat, milk fortified with A, fish oil and eggs. Bete-carotene is found in red, yellow, and orange vegetables and fruits, and many dark-green leafy vegetables."
WHOA! I don't want any of that so let's find that converter! The SP nutrition tracker lists measures in IUs, whereas the Reference Section measures in mcgs.
While I search for the converter, I'm also look through my food journal to see if the bulk of my Vitamin A comes from animals or fruits and vegetables. The most harmful of the two sources is retinols, the animal source. If it turns out that the bulk of my Vitamin A is from retinols, I'll be hunting healty alternatives.
If you aren't tracking your Vitamin A on the nutrition tracker, perhaps you should be.
