There's been quite a flurry of food news lately, the most recent being reports that ever-increasing amounts of dyes in prepared food may be injurious. Duh. C'mon, didn't we already go through a big scare about red dye number something-or-other, decades ago? What makes this such a big revelation now?
Part of it, I suppose, is that the use of dyes has increased considerably. Another part may be that, while we might expect that the bright blues and reds in a bag of M&M candies are produced with dyes, it's somewhat less intuitive to divine that the nice pink color of your strawberry yogurt also comes from dye, not fruit.
How injurious? A lot will depend on how much prepackaged food you eat. The Washington Post pictured five common affected foods. We don't buy any of them, nor most of the others that are cited as examples. Buy fresh and cook your own meals, and this dye problem will disappear. Otherwise, maintain a healthy skepticism about any packaged foods you buy. But then you were already doing that, weren't you?
