Are you a junk-food junkie? Here’s what you need to know.
It’s the 21st century and “junk food” has gone global. For better or for worse (mostly worse), junk food is now available all over the world. We see it most everywhere we go — in grocery and convenience stores, fast-food restaurants, on television — usually looking very appealing. But just what are the facts about junk food?
“Junk food” generally refers to foods that contribute lots of calories but little nutritional value. Of course, what’s considered “junk food” depends on whom you ask. Some might say pizza is junk food, for example. But I personally don’t think so, since it contributes real food with nutrients, like cheese and tomato sauce. Add whole-wheat or part whole-wheat crust, plus veggies as a topping, and I’d say pizza completely exits the junk food category.
One problem with junk foods is that they’re low in satiation value — that is, people don’t tend to feel as full when they eat them — which can lead to overeating. Another problem is that junk food tends to replace other, more nutritious foods. When people drink lots of soda, for example, they are usually not getting plenty of low-fat dairy or other healthful beverages like green tea or orange juice. When they’re snacking on chips and cookies, they’re usually not loading up on fruits and vegetables.
Most “junk food” falls into the categories of either “snack food” or “fast food.” And then there are things like breakfast cereals. They seem innocent enough, but some of them could definitely be considered “junk food,” as they mostly contain sugar or high-fructose corn syrup and white flour or milled corn. Continue reading »
