Today I ran a Google search on the phrase “than a quart of milk” and discovered that the misinformation I wrote about several years ago is still persisting.
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 of calcium per cooked cup. Cows milk has about 300 mg of calcium per cup. See the USDA Free Online Nutrition Database
My guess is that somebody accidentally a zero somewhere.
At the time I wrote this post that cookbook author’s site was still 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. In print. Somebody made a mistake somewhere and cookbook authors have been perpetuating this misinformation down the line.
Bottom line: do not not trust cookbook authors ( or athletes ) for nutrition information.
They enough of an interest in food to remember some things they have heard about nutrition, but they don’t have enough interest to look things up and be sure of what they are talking about in regards to nutrition.
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
