Today, I ran across the same factual error, with the exact same phrase, on a new cookbook author’s site. I Googled on “more calcium than a quart of milk” and found at least 5 other sites making this error. All these years later.
The USDA Nutrition Database is the standard for nutrition information. Almost all of the nutrition software out there, on and offline uses it. Now, in 2012, they have searches that can be bookmarked. Here you go, in case you are curious to see for yourself that quinoa does not have more calcium than a quart of milk:
It is just AMAZING that one person posting a factual error on the web, can spread that error for over 5 years and even have it published in hard copy books.
At least five years ago a cookbook author wrote on her web site that one cup of cooked quinoa has as much calcium as one quart of cow’s milk.
Well, quinoa has about 32 mg per cooked cup. Cows milk has about 300 mg per cup. My guess is that somebody jumbled a zero somewhere.
That website, which shall remain nameless ( I’m not out to bust on anyone ) is still up, uncorrected, years later. I have heard people claim to have contacted this author with information about her mistake.
Today, years later, I was reading a cookbook I’ve been into for the last month and the author wrote the exact same mistake. Somebody made a mistake somewhere and cookbook authors have been perpetuating this misinformation down the line.
Bottom line: do not not trust cookbook authors for nutrition information.
BTW, if you want calcium without the digestive discomfort of lactose intolerance, allergies and sex organ cancers of cow’s milk you can find plenty of calcium in these foods
