Everyone loves Dairy Queen's blizzards, but do you know how unhealthy they are for you? The blizzards contain ingredients like corn syrup, hydrogenated oil and additives like artificial flavors and preservatives. These ingredients are much more harmful than you think. Eating foods with corn syrup in it for just a period of six weeks can cause your brain to not function properly. You could lose ability to learn, comprehension skills, and memory. Blizzards also contain way to many calories for one meal. Some of the blizzards they sell make up half the recommended number of calories for a whole day! The one with the least calories is the "Butterfinger Blizzard" (470 calories) and that's a size small. A large "Butterfinger Blizzard" contains 990 calories. The FDA says that any ice cream product over 400 calories is considered high. Blizzards also contain a high amount of fat. A small "Butterfinger Blizzard" has about 25% fat and 50% saturated fat. A large has 54% fat and 105% saturated fat. The FDA considers fat levels high if they are over 20%. The only positive thing about a Dairy Queen blizzard besides the taste is that it does contain some healthy nutrients like iron, vitamin A and calcium. The amount of vitamin A in a small "Butterfinger Blizzard" is 15%, iron 10%, and calcium 30%. While these are good things, it doesn't make blizzards that much better. They are defiantly more unhealthy for you than healthy.
