For a number of years now, we have subscribed to a little magazine called Nutrition Action Healthletter, published by The Center for Science in the Public Interest (CSPI). It is very affordable, has no advertisements (love that), and is a more factual/scientifically based presentation of food and healthy living information. In other words, straightforward information, without hype. You won't find any Oprah testimonials here (or any other for that matter) or much "new agey," experiential, drama. I would recommend it.
Deceptive advertising of "healthy" foods is often revealed. They usually have one or two comparative articles per issue which are usually pretty interesting. For example, one month they might compare the fat and sodium content of common main dishes at various well-known chains. In the one that arrived this week they compare various brands of hummus, salsa, guacamole, and bruschetta.
Anyway, to address the leading question...
For some reason, I have been on a guacamole kick the past month or so. There's only one other person in the family who will even consider touching the stuff, which means, it's pretty much all mine. It's has probably just been in the past 10 to 15 years that I even knew what the stuff was, let alone ate it. And just this spring that it has become a regular part of my diet. This was partly due to the discovery of a super easy recipe for it, that I'm sure has more sodium than would be acceptable by the standards of the above mentioned article. Not to mention the health detriments of the corn chips that are the preferred vehicle for guacamole consumption.
