All-Natural - This is the most meaningless and confusing label of them all. There are no regulations regarding foods labeled as "all-natural" except for meat and poultry, so basically a company can put that on most anything. Though you would think that something labeled "all-natural" would indeed contain ingredients that are in fact natural, many contain processed and chemically created ingredients. For example, I found High Fructose Corn Syrup which is derived chemically from corn starch in some "All-Natural" products, and HFCS is definitely something to avoid. Even "all-natural" meats and poultry can contain hormones and antibiotics!! The USDA requires "natural" meat and poultry to be free of artificial colors, flavors, sweeteners, preservatives and ingredients, but it does not regulate how the sources of those foods were raised.
Unless you see the USDA label, your best bet is to read the entire package and ingredient list to see what is in it!
