So I looked up the Vitamin A contents of Heinz ketchup and Kraft Singles (the highly processed "cheese" used in fast food cheeseburgers). Each say 2% RDV per serving, that's roughly 20mcg per serving. I'm not sure below what level constitutes deficiency. Perhaps that small amount is enough.

Hitting 4-6% of the recommended daily value over a sustained time is likely severe deficiency.

  Hitting 50% over time is noticeably inadequate at a population level. https://academic.oup.com/jn/article/132/9/2920S/4687708 https://academic.oup.com/jn/article/132/9/2920S/4687708
