An article by the BBC on “The world’s most nutritious foods” ranks the healthfulness of foods on the basis of an article at the supposedly scientific PLOSone journal, titled “Uncovering the Nutritional Landscape of Food”. That study is based on a dataset that entirely ignores antioxidant-content of foods. Antioxidant-content has come to be recognized during recent decades as constituting perhaps the most important factor in nutrition. It’s probably even more important than vitamin-content and than mineral-content and than protein, carbohydrate, and fat content. So, the basis upon which the article’s ranking was done is the factors that were known about, in 1950, to be important, but that are now known to be far less determinative of a person’s health and longevity than are foods’ anti-oxidant contents. Neither the article nor its underlying dataset even so much as just mentions “oxidant” anywhere. The authors of the BBC and PLOSone articles and of the underlying dataset were apparently entirely ignorant of the findings in nutritional research during the past 60+ years — findings about antioxidants, which have transformed our understanding of nutrition. (Furthermore, there were many other important methodological flaws producing that PLOSone ranking, not only its ignoring antioxidants.)
This is not unusual.
(Incidentally, “ORAC Values: Antioxidant Values of Foods & Beverages” is a ranking of foods on the basis of antioxidant-contents, as measured by ORAC; and this is likely a far more accurate indicator of the relative healthfulness of foods than is the ridiculous BBC-PLOSone ranking — but far fewer people are being exposed to it.)
Here’s another example of the untrustworthiness of news-media and of other allegedly nonfiction presentations, even in many ‘scientific’ journals — but this one will be an example from what has become overwhelmingly the world’s leading encyclopedia: Wikipedia.
