Most chicken nuggets from fast food restaurants contain 50 percent or less chicken. Along with the chicken, they contain fat, blood vessels, nerves, bone and cartilage. Many are a combination of chicken pieces rather than low-fat white meat chicken, and most are high in salt, sugar, fat and calories.
Most chicken nuggets are made from these less expensive parts than the healthy white meat of a chicken. While these chicken pieces are not harmful, they are not healthy food.
Most chicken nuggets from fast food restaurants contain chemical additives and preservatives that are unhealthy for consumption. Some nuggets contain as many as 30 ingredients along with chicken. Some nuggets contain dimethylpolysiloxane, an ingredient used in Silly Putty, and propylene glycol, an ingredient in antifreeze. Ingredients like these have been designated safe by the Federal Drug Administration, but critics believe that simply means that these additives have not be found to be unsafe.
Many nuggets also contain artificial ingredients that experts believe should not be in food. Nuggets also contain salt, sugar and monosodium glutamate, which causes headaches, sweating and flushing. Many people are surprised to find that nuggets contain added sugar, and one order of chicken nuggets from McDonald's contains over one-third of the daily recommended amount of salt in an adult diet.
