A study slated to be published in October was mentioned in CBC news yesterday for its less-than-surprising conclusion: Consumers who make a "healthier" food choice are more likely to splurge on side dishes, beverages, or desserts that more than make up the difference - in calories and unhealthy ingredients.
I could discuss at length the psychological factors that make a dieter reach for a coke or chocolate bar after they've been "good" by ordering a low-fat sub instead of a burger - but you know all that already.
What this kind of study highlights, for me, is the extent to which claims by fast-food restaurants that they serve healthier fare (Subway's low-fat subs, McDonald's salads) are little more than a way to trick consumers into buying more - and how easily we fall for it.
I also noticed that the CBC article makes little mention of the actual (as opposed to advertised) merits of the "health foods" in question. Are "healthy" fast food options really better? Is a sub made on preservative-enriched white bread any healthier than a big mac... or only lower in calories? Food for thought.
