Hello QDT listeners,
This week, Monica Reinagel explained the concept of a food matrix, and the way it affects our ideas of nutrition. It all started when a listener asked:
“Can you discuss the concept of food matrix and how it affects the nutritional attributes of foods we eat? I heard it discussed on a podcast—and it seems to provide a strong rationale for why a whole food diet might be better for us. Is there any validity to this concept?”
Foods are more than just a collection of nutrients. Those nutrients are delivered in what we are now referring to as a food “matrix.” The term is thrown around a lot these days, but it's not always used to mean the same thing. Sometimes, people are just referring to the level of processing involved. But it’s more than that.
José Miguel Aguilera writing for Critical Reviews in Food Science and Nutrition defines it this way: “The food matrix may be viewed as a physical domain that contains and/or interacts with specific constituents of a food (e.g., a nutrient), providing functionalities and behaviors which are different from those exhibited by the components in isolation or a free state.”
Translation: The whole is not always equal to the sum of its parts.
The format or matrix of a food can impact everything from the amount of energy that your body will extract from it (which we measure in calories), to how it tastes, to what it does to your blood sugar, to how full you feel after eating it. There are a lot of ways that the concept of a food matrix can change how we think of nutrition generally. For the full story on the research being done here, listen to the latest Nutrition Diva episode. If you prefer to read the transcript, you can click the transcript tab on that page.

| Elsewhere |
Richly emotive and darkly captivating, with elements of Shirley Jackson’s “The Lottery” and the imaginative depth of Margaret Atwood, Elsewhere by Alexis Schaitkin (Saint X) conjures a community in which girls become wives, wives become mothers and some of them, quite simply, disappear.
