In this way, the total recommended amount of carbohydrate is 450 g. This amount is the minimal amount of carbohydrate needed to meet the needs of soldiers experiencing intense physical activity. Carbohydrate Needs for Cognitive Function. Although some studies described above have found essau carbohydrate may improve vigilance and reaction time, improvements in other sservice domains associated with carbohydrate consumption have not been found.

Hence, there is a lack of conclusive results on the effect of carbohydrate on cognitive performance. Also, most studies have relied on subjective methodologies that have not been validated for the scenarios of concern. The committee recommends that researchers seeking to determine the effects of carbohydrate on cognitive function develop and use tests that fall within the domain of neurocognitive functioning e. In summary, although some studies have found that carbohydrate may improve vigilance and reaction time, there isno conclusive evidence to recommend specific levels of carbohydrate to enhance cognitive function.

The type of carbohydrate in the food ration menu items should be a esday of complex and simple carbohydrates essaay that the food is palatable not too sweet. Fructose as a monosaccharide should be limited due to the association esay dietary fructose and diarrhea Skoog and Setvice, 2004. Because reports that consumption of 25 g of fructose as a monosaccharide for three consecutive days caused malabsorption symptoms in healthy adults Born et al. The supplemental carbohydrate should be available in easily digestible forms, such as powder to mix in with water to a 4-8 percent solution Coyle and Montain, 1992in carbohydrate gels, or in candy.

The authors concluded that such a delay is not optimal acaademic fluid replacement Murray et al. Therefore, the concentration and possibly type of carbohydrate should be an important consideration when developing acasemic carbohydrate beverage. As mentioned in the section above, academif carbohydrate delivered in fluid form should provide the most benefit to performance compared to carbohydrate alone Fritzsche et al. Although the consumption of high amounts of total dietary fiber is desirable to reduce the risks of chronic diseases, in the case of short-term missions, avoiding diarrhea and constipation and decreasing stool weight are of greater concern to the military.

Seevice, it is recommended that the range of dietary fiber in the assault ration be based on a minimum amount to avoid constipation to the extent possible and on estimates of the intake of young men in the US population. It is assumed that these amounts should prevent diarrhea and constipation. The estimated median intake and the 95th percentile intake from the Continuing Survey of Food Intake for Individuals in 1994-1996 CSFII, 1998 in the United States for men 19-30years old is 17.

The type of fiber servoce also important. Both viscous and nonviscous fiber typically found in foods of plant and vegetable origin are important IOM, 2002a. Beta-glucan might be included as an example of a nonviscous, fermentable fiber. Beta-glucan has been evaluated as an immunostimulant and can be fermented into short-chain fatty acids in the large bowel, servixe improves intestinal function i. Specific Requirements for Health Claims. The committee concluded that a mixture rather than a single source of fiber might be better tolerated physiologically and may help prevent constipation.

Therefore, the committee recommends that the amount provided include nonviscous, fermentable fiber e. Investigate the type of carbohydrate disaccharides versus starches that best enhances physical and cognitive performance. Confirm the effects of carbohydrate on performance and cognition academic essay service conditions analogous to the high-stress situations of military operations.

The ration should academic essay service a balance of dietary fatty acids between monounsaturated, polyunsaturated, and saturated fats, essaj at least 17 g linoleic acid and 1. This balance can be determined by food formulation criteria. There acwdemic no recognized benefit to modifying fatty acid type in the ration or to adding structured lipids. The primary reason for fat in the ration is to provide a readily digestible, palatable, energy-dense source of calories to help soldiers perform physically and cognitively demanding military operations.

Since appetite may be depressed under conditions of high-intensity physical activity and stress, maximal consumption of the ration is a primary goal. Fat provides a highly palatable source of calories that can be expected to promote ration intake. Among energy academic essay service, fat has been shown to be less satiating Gerstein et al. In addition, esssay studies indicated that greater satiety results from consumption of foods higher in protein and carbohydrate than fat see also Chapter 3. While the desire to increase ration consumption as much as possible would support the addition of a higher level of fat, increasing the fat content would result in a decrease in the amount of carbohydrate or protein acaademic the ration.

The committee believes that, although increasing consumption is desirable, satiety is only one of the many factors that influence consumption, and the exsay data do not yet provide an unequivocal answer. A better understanding of the influence of nutrient composition on satiety is needed before considering it as the basis for nutrient level recommendations.
