Ferrous fumarate/calcium carbonate interactions affecting electrolyte status of physically active humans: Nutritional knowledge, attitudes and food practices among competitive athletes, recreational athletes and non-participants
Abstract
The objective of the first study was to determine ferrous fumarate/calcium carbonate interactions affecting sodium, potassium, and chloride status of physically active humans consuming laboratory diets containing ferrous fumarate and calcium carbonate supplementation. The 56 day study was divided into four experimental periods of 14 days each: 30 mg ferrous fumarate plus 900 mg calcium carbonate, 30 mg ferrous fumarate, 900 mg calcium carbonate and no supplement were given. Calcium supplementation resulted in significantly higher potassium retention (p $<$ 0.05) and numerically lower sodium and chloride retention. The combination of calcium and iron supplementation resulted in the lowest urinary sodium to potassium ratio. The objective of the second study was to compare nutrition knowledge, attitudes and food practices of competitive athletes, recreational athletes and non-participants. All students enrolled in an Introductory Nutrition class in which sports nutrition was stressed, were asked to participate in the research study. The results from assessment of food group consumption using the food guide pyramid indicated that consumption of foods from the grain group, vegetable group, fruit group, dairy group, and meat group were not significantly different among the groups, however, competitive athletes consumed significantly more fats, oils and sweets than recreational athletes and recreational athletes consumed more than non-participants (p $<$ 0.01). The total mean scores on the nutrition attitude and knowledge questionnaire were not significantly different, however, combined athletes (competitive athletes and recreational athletes) had significantly lower scores on some of the nutrition knowledge questions (p $<$ 0.05).
