London, 2001 (ResearchWire) - Food and drinks companies currently rate dairy products as the most important food and drink category for targeting senior consumers, scoring 3.7 on an importance scale of 1 to 5. This is because dairy products are high in nutrients and have been a major area of innovation in nutraceuticals. However, the importance of frozen foods is expected to rise substantially, reaching 4.6 by 2005, since they save on shopping trips for less mobile consumers.
