A control unit is attached to or embedded within a refrigeration appliance to monitor electric power voltage and / or frequency supplied by the mains. If the unit detects a sag or peak in either the voltage or frequency, the control unit either separates any high demand elements of the appliance from the mains to reduce demand in a sag or energizes the elements in a peak. When the control system separates the refrigeration compressor from the mains, a food spoilage monitoring system monitors the food storage compartments. This system utilizes food industry temperature and time algorithms to ensure the food does not spoil. If food spoilage could occur, the unit re-energizes the compressor to allow it to lower the temperature provided the power is sufficient to operate the compressor unit without damaging it. Once the sensed temperature is restored to a safe level, the unit separates the compressor from the mains.

The present invention uses market research data to access nutrient intakes of a population. Dietary collection using 24-hour recall generally does not reflect a pattern of “usual” intake behavior for a population group. To determine the impact of food consumption patterns on nutrient intake, a unique methodology using 14-day food diary was developed. The food industry has traditionally used detailed food records to track the consumption of specific branded food items and monitor the growth of food categories, but some of the most valuable databases available concerning longer-term (e.g., 14-day) food intake do not record portion size on an individual consumption basis. Other databases based on shorter-term (24-hour recall) survey periods record portion sizes but are not very representative of eating habits. The preferred exemplary embodiment integrates two such databases with a third data set providing detailed nutrient information for each of a wide variety of foods consumed to provide a combined database for processing nutrient intake reports using statistical analysis. This flexible system allows the user to categorize the population based on “usual” consumption of food categories, specific foods and / or specific brands of foods and determine dietary differences versus their “non-using” counterparts.
