Nutrition Labeling--Exemptions

Under NLEA, some foods are exempt from nutrition labeling such as food which is only bought for immediate consumption such as food sold in hospital cafeterias , airplanes , and food service vendors such as small cookies.

Ready to eat told even if it is not for immediate consumption but it is cooked just right there such as baked goods ,deli and candy
