In a
previous post I questioned that dietetics is a science, because it seems to
follow quite often what can be considered alternatives of fashion, and I gave
some examples. In this article I’m going to add a few more, along with a general
consideration.
- The expiration date of yogurts. A few years ago, there were several books
published and speeches made, asserting that yogurt should never be eaten
just one day after its expiration date. Of course, no expired food should ever
be used to help poor people. However, any quality expert knows that
expiration dates always include a safety margin that can sometimes be
quite long (days, weeks, or even months). Therefore, some kinds of very recently
expired food are probably within that safety margin and can be eaten
without problems. Not to mention the fact that there are products (such as
yogurts) that don’t need an expiration date, as their substance is not
spoiled, even though it may lose nutritional or flavor properties. This is
why lately, in this type of products, there is no longer talk of an expiration date, but of a preferred consumption date.
