Potential database bug with Lutein+Zeaxanthin for turnip greens?
I noticed under "Antioxidants" that if I put one cup of kale or collards, I get a similar value for Lutein+Zeaxanthin (1315 and 1557 micrograms respectively) but if I put the same amount, one cup, of turnip greens, I get over 7000 micrograms. However, when I google around, it does not appear that turnip greens has a large (multiple) amount of Lutein+Zeaxanthin, it appears to have a similar amount. Just one example:
(I found others).
Is there something I don't know, or is this a bug in the database?
