157 Lactose Intolerance Lactose maldigestion is the inability to digest and absorb lactose, the main carbohydrate/sugar in milk. Lactose maldigestion can result in symptoms of lactose intolerance, such as abdominal distension, gas, abdominal cramping, and diarrhea. Lactose intolerance is NOT an allergic (immune) reaction and individuals with lactose intolerance can usually tolerate a small amount of lactose in their diets. Milk Protein Allergy Food allergens are proteins that can provide an immune response (rash, itching, runny nose, nausea, vomiting, diarrhea) in some individuals. The proteins in milk are casein and whey. Individuals with a milk-protein allergy should avoid all milk-protein-containing ingredients. Storage Times/Temperatures for Adult Nutritional Products TEMPERATURE GUIDELINES Our general recommended storage temperatures are between 32 and 95 degrees F. The most desirable temperature range for storage is between 55 degrees F and 75 degrees F. Prolonged exposure to temperatures below 32 degrees F or to direct heat above 95 degrees F could affect the physical consistency of the product. While the product within the sealed package is of sound nutritional quality, a change in the consistency of the product could temporarily affect the appearance, flavor, and other sensory attributes. We therefore do not recommend use of product exposed to adverse temperatures.
