Let’s take a look at this article, which I find somewhat misleading.
First, the time periods the bread diets were evaluated were very short. What’s the long term effects of the different diets? Second, while there may be individual variation in, for example, glycemic response, fact is, your average person is not going to have their metabolic responses to bread types analyzed. You’ll get the most “bang for the buck” with respect to population health providing generally healthy guidelines. Third, whole wheat bread has advantages of white bread with respect to fiber (the long range effects of which on colon cancer risk is going to be measured in years/decades, not a week or two) and vitamin content.
When studies like this are reported without giving all the context, it gives the general public license to gorge on food that is likely not optimal for health - looking forward to an entire lifetime, not just for a week or two.
Now, that doesn’t mean the findings should be ignored. Maybe white bread isn’t as bad as it has been made at to be – but that needs to be evaluated over a long time frame. The bottom line though is that whole wheat has a number of advantages for the average person and I don’t see why that should be ignored. If you are going to eat a certain volume of bread, why not maximize fiber and various micronutrients?
