The new boxes of Total cereal proudly exclaim:
"NOW! The most calcium and Vitamin D of any leading cereal!"
(Although I couldn't find a photograph of these boxes, the slightly outdated one on the left boasts the 100% calcium claim).
A cup of this retooled version provides a day's worth of calcium (1,000 milligrams) -- too bad our bodies can only metabolize approximately 500 milligrams at a time.
In other words, that bowl of cereal actually provides, at most, half a day's worth of calcium.
Not bad by any means, but not quite what the food label says.
I am also concerned about a cereal that attempts to provide a day's worth of iron and calcium in the same serving, since high amounts of calcium (anything above 300 milligrams, per the research literature) are known to interfere with the absorption of
non-heme iron.
