Many store-bought coleslaw dressings contain sugar, and mayonnaise made from unhealthy oils, additives, and preservatives. These ingredients may also contain gluten and dairy which can be no good for people with sensitivities to these food. The ingredients will determine the coleslaw’s health. Though it does contain vegetables if it's laden with a lot of unhealthy fats, sugar, and preservatives it’s not the best food in terms of health. When in doubt check out the label. If the ingredient list is a paragraph long, contains added sugar and has a warning that it contains dairy, wheat, or gluten it may not be the best choice. The quality of the coleslaw is important too. If it looks wilted or has been sitting in the store for a long time don’t buy it. The health of store-bought coleslaw depends on the ingredients and visual appearance of the slaw. Sometimes making your own is a better option.
