Puffed corn - Nutritional Value
Puffed corn provides a significant amount of energy - 100 g provides 374.7 kcal. The caloric content of puffed corn increases significantly when butter or vegetable oil is added. For comparison - a cup of puffed corn weighs only 8 g. This treat is rich in carbohydrates, a large portion of which is dietary fiber. However, the fat content in puffed corn consists entirely of saturated fatty acids. The nutritional value of 100 g of puffed corn is as follows: - Energy value: 374.7 kcal, - Protein: 12.9 g, - Fat: 4.5 g, including saturated fatty acids: 4.5 g, - Total carbohydrates: 77.9 g, - Dietary fiber: 14.5 g.
Reduction in vitamin and mineral content
Popcorn is produced from corn, the seeds of which undergo a prolonged and intensive heat treatment, leading to a substantial decrease in the levels of vitamins and minerals present in the corn seeds.
Popcorn as a rich source of dietary fiber
In comparison to other snacks, popcorn is a very valuable source of dietary fiber and has a beneficial impact on the human body by enhancing the peristalsis of the intestines, facilitating evacuation, eliminating toxins, excreting excess cholesterol and triglycerides with stool, or delaying the absorption of glucose from the digestive tract.
Popcorn as a source of antioxidants
M. G. Coco and J. A. Vinson, in their study, demonstrated that popcorn contains substantial quantities of antioxidant compounds, including phenolic acids. A significant portion of these antioxidants is concentrated in the kernel and seed coating of the corn, and the amount of them is not diminished during the expanding process. The high polyphenol content in popcorn can be attributed to the use of specific corn varieties with a hard and less porous hull in its production. All of this allows the corn to explode and retain biologically active compounds.
Corn under the magnifying glass of a healthy snack
Corn, as a product rich in nutrients, appears to be an attractive snack option for those seeking a healthy lifestyle. The contained ferulic acid helps in reducing oxidative stress, which negatively affects human health, and in lowering blood pressure values. Furthermore, it positively affects the lipid profile and carbohydrate metabolism, making it an effective preventive measure against heart disease and diabetes.
Corn kernels as an unhealthy snack
Americans perceive popcorn as a product rich in whole grains. On one hand, it is understandable, since it is made from whole kernels of corn. However, on the other hand, it is a highly processed product with a low nutritional value. Additionally, it is consumed with a large amount of salt and often with added fat. Such a product delivers a considerable number of empty calories, which can have a negative impact on health. Nevertheless, popcorn as a good source of fiber and antioxidants is a better choice than other snacks.
