Some words and standards can indicate quality.  &quot;Pasture Eggs&quot; for example, are more expensive but also a better product.  Also, going to a farmer&#x27;s market and buying from producers directly instead of a supermarket is one way to shop for quality.<p>I wouldn&#x27;t want to use nutritionism as the definition of quality, because so far nutritionism has been too reductionist to capture the full picture.  There&#x27;s a wide variety of micronutrients that turn out to be useful, but are easily depleted from the soil in a monoculture.  Are you getting your Vitamin K12?  Selenium?  Zinc?  Copper?  Choline?  Are the animals you eat getting theirs?
