The Effects of Varying Ratios of Minerals and Vitamins to Calories Consumed during Food Intake Restriction on Physical Condition of Rats and Man: Information from a Rat Experiment and Literature Review
Abstract
In order to determine whether on a restricted caloric intake a higher ratio of minerals and vitamins to calories consumed than normal for ad libitum food intake is desirable, an experiment with rats was conducted and a literature review performed. Male, adult rats received a semipurified diet with two mineral-vitamin levels and two levels and kinds of fat. Under the experimental conditions, at a 40% of average ad libitum food intake, a higher ratio of minerals and vitamins to calories consumed than that normal for ad libitum food intake did not result in a significant difference in treadmill running performance. However, the relatively higher mineral-vitamin level increased water consumption significantly. The rats receiving 15% of calories from corn oil ran significantly longer than the groups receiving 41% of calories from butter. Literature reports indicate that during complete caloric deprivation additional mineral and B-vitamin intake often is beneficial. Extracellular water loss during the first days of caloric restriction has been reported to be positively correlated with the Na content of the diet prior to the period of restriction.
