Is There Such a Thing as "Junk Food"?
A number of nutrition professionals bristle at the term junk food. After all, it is the overall eating plan that counts, not the stray high-sugar, high-fat, low-nutrient item that gets indulged in here or there. However, there are nutritional consequences to choosing items like soda and chips over healthier foods.
Health Effects of Junk Foods
Not surprisingly, the more junk foods that make up one's diet, the more calories consumed; also, the more fat and saturated fat eaten, and the less fiber. Moreover, as junk food in the diet goes up, the consumption of vitamins A , B6 , B12 , C , folate , calcium , and iron go down. The lower the blood levels of many of those nutrients, too. Furthermore, people who eat more junk food have lower levels of the good HDL-cholesterol that works to clear plaque from the arteries. And they have higher levels of homocysteine, a blood chemical that may be associated with increased heart disease risk.
Fats and Sweets Get All the Attention
Advertising may also be fueling the desire for less nutritionally desirable choices by placing more attention on these products. While we do not see advertisements for carrots, we often see advertisements for chips and soda.
Studies have shown that children are heavily influenced by food advertising. For example, researchers at the Rudd Center for Food Policy & Obesity at Yale University found that children who view more advertisements for junk food end up eating more of this type of food.
Many Americans are eating double cheeseburgers, sugar frosted flakes, soft drinks, candy bars, and other high-fat, low-nutrient foods on a daily basis. The whole debate about the term junk food may prompt us to take a closer look at what we are eating and what our children are eating.
These foods give us a lot of pleasure, but they should not be eaten every day. We should eat less of these foods and choose healthier options whenever possible. Choosing to include more fruits, vegetables, and whole grains can help to improve our overall health.
