Vitamin A?

Can anyone tell me why the Vitamin A numbers have changed? I have been doing recipes and I like to make sure I get all the nutrients I need, I checked today my recipes and all of them say low in Vitamin A? Has Vitamin A been altered so people need more? Has some foods been said to not have as much Vitamin A? What is going on?

What is the point of using a tracker if they don't give you the right numbers? Tomorrow is every other nutrient going to be not enough? What's the point in tracking anything? Might as well just eat a decent amount of healthy food and not even look at the numbers. What's the point if they can't get the numbers right.
