Challenges in Using the Dietary Reference Intakes to Plan Diets for Groups

NUTRITION REVIEWS, Issue 8 2005
Suzanne P. Murphy PhD
A recent report describes a new paradigm for planning the dietary intakes of groups, the goals of which are to achieve low prevalences of both inadequate and excessive intakes. However, there are many challenges involved in properly implementing these methods, and pilot studies are urgently needed. For individuals, the target for nutrient intakes is usually the Recommended Dietary Allowance (RDA); for nutrients without an RDA, the Adequate Intake (AI) can be used. Intakes should be planned so they do not exceed the Tolerable Upper Intake Level (UL). Several applications illustrating how to use the DRIs for planning the diets of individuals have been published, so this review will focus primarily on the methods that are recommended for planning the diets of groups.

Jana A. Hovland MS
BACKGROUND: Children in Appalachia are experiencing high levels of obesity, in large measure because of inferior diets. This study screened the dietary intake of third graders residing in 3 rural Appalachian counties in Ohio and determined whether the Food, Math, and Science Teaching Enhancement Resource Initiative (FoodMASTER) curriculum improved their dietary intake. METHODS: Dietary intake was measured for 238 third graders at the beginning of the 2007 to 2008 school year and for 224 third graders at the end of that year. The FoodMASTER curriculum was delivered to 204 students (test group). Intake was measured using the Block Food Frequency Questionnaire 2004. The final analysis included 138 students. RESULTS: The FoodMASTER curriculum did not significantly affect the diets of the students in the test group, as no significant differences in intake of macronutrients, specific nutrients, or food groups were found between the test and control groups. Majorities of students did not meet the Recommended Dietary Allowance or Adequate Intakes for fiber, calcium, iron, vitamin A, and vitamin E. The students as a whole did not meet the MyPyramid recommendations for any food group, and nearly one fifth of their calories came from sweets. Significant differences in percentages of kilocalories from protein and sweets and in servings of fats, oils, and sweets were seen between groups of higher and lower socioeconomic status. CONCLUSIONS: Energy-dense foods are replacing healthy foods in the diets of Ohio children living in rural Appalachia. The prevalence of poor dietary intake in Appalachia warrants further nutrition interventions involving programming for nutrition, such as future FoodMASTER curricula. [source]


Vitamin D in health and disease

PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 5 2010
Matteo C. LoPiccolo
Background/purpose: Investigations have revealed that vitamin D plays an important role in many areas of health and disease. Questions over whether sun avoidance and sunscreen use will decrease vitamin D levels may concern clinicians when counseling patients at risk for vitamin D insufficiency. A review of the role of vitamin D in health and disease, the impact of photoprotection and skin type on vitamin D levels, and recommendations for adequate vitamin D intake is provided to aid clinicians in counseling patients regarding these issues. Results: Review of the literature indicates that adequate vitamin D intake is associated with decreased risk of falls and bone fractures in the elderly, breast and gastrointestinal cancer risk, cardiovascular disease, and possibly all cause mortality, diabetes, and multiple sclerosis. While skin type does affect vitamin D levels, regular use of sunscreen is not associated with vitamin D insufficiency. Conclusions: Adequate intake of vitamin D is important for maintenance of good health, and may be achieved through diet and oral supplementation. Intentional or prolonged exposure to ultraviolet light should not be used as a means of obtaining vitamin D. [source]


Calcium intake and its relationship with adiposity and insulin resistance in post-pubertal adolescents

L. C. Dos Santos
Abstract Background, Dietary calcium intake has been described as being a negative contributor to adiposity. In adolescents, this relationship is not well established. The objectives of the present study were to compare the calcium intake of normal-weight and obese adolescents and to evaluate its relationship with adiposity and insulin resistance. Methods, A cross-sectional analysis of 96 post-pubertal adolescents; 47 normal weight and 49 obese, mean age 16.6 (SD ± 1.3) years. Body composition was assessed by dual-energy X-ray absorptiometry. Dietary intake was evaluated using a 3-day dietary record. The biochemical evaluation comprised the measurements of serum lipids, lipoproteins, glucose and insulin. Insulin resistance was calculated using the Homeostasis Model Assessment of Insulin resistance (HOMA-IR). Results, The mean calcium intake, adjusted for energy, was lower in obese adolescents, 585.2 (±249.9) mg, than in normal weight adolescents, 692.1 (±199.5) mg. Only 4% of adolescents had an adequate intake of calcium. Calcium intake was inversely associated with body trunk fat, insulin and HOMA-IR in the obese group. The quartile analysis of calcium intake provided evidence that girls in the highest quartile had decreased adiposity and insulin resistance. Conclusions, This study showed a negative relationship between calcium intake and body fat and insulin resistance, mainly in obese girls, and demonstrates the importance of an increased dietary calcium intake.

Frequency of under- and overfeeding in mechanically ventilated ICU patients: causes and possible consequences

Abstract Introduction, In critically ill patients enteral nutrition (EN) is frequently associated with underfeeding and intolerance, whilst parenteral nutrition (PN) has been associated with a greater risk of infectious complications and overfeeding. Materials and methods The adequacy of nutritional support provided to critically ill patients was prospectively recorded and compared with estimated requirements. The incidence of, and practices contributing to, under- (<80% of energy requirements) and overfeeding (>110% of energy requirements) were identified. Results, Overall patients received approximately 81% and 76% of prescribed energy and protein intakes respectively. Underfeeding occurred on 50.3% of days. Reasons for patients failing to achieve adequate intakes included, fasting for airway management procedures (21%) and gastrointestinal intolerance (14%). Overfeeding, although less common (18.6% of days), was more likely to occur in patients with a tracheostomy requiring prolonged mechanical ventilation (>16 days). The combination of oral and nasogastric feeding or use of nutrient-dense feeds were most frequently associated with overfeeding. Discussion, The overall adequacy of nutritional intakes in the present study was similar to those reported elsewhere. However, the incidence of overfeeding was greater than anticipated and occurred in patients already experiencing delayed weaning from mechanical ventilation. [source]


Drink consumption in British preschool children: relation to vitamin C, iron and calcium intakes

Objective To examine the impact of soft drinks, fruit juices, milk and tea consumption on vitamin C, iron and calcium intakes in a large, representative sample of preschool children in the UK. Design Secondary analysis of 4-day weighed dietary diaries. Sample 1675 children aged 1.5,4.5 years living in the UK in 1992/993. Results Fruit juice consumers, but not soft drink consumers, had higher vitamin C intakes and higher plasma ascorbate levels than nonconsumers (P < 0.001). However, overall intakes tended to exceed the RNI and 45% of children still had adequate intakes without the contribution of soft drinks and 56% without the contribution of fruit juice. Children who did not consume fruit juice or soft drinks were no more likely to have depleted levels of vitamin C than consumers. Tea drinkers had diets which were lower in iron and vitamin C than nonconsumers (P < 0.005). They had lower levels of haemoglobin (P < 0.05) but not ferritin. Children under 4 years old were less likely to meet the RNI for iron if they were tea drinkers (P < 0.005) but no more likely to be anaemic. Calcium intakes were significantly higher for whole milk consumers than for nonconsumers (P < 0.005) and 73% of overall calcium intake was predicted by quantity of all milks consumed. Whole milk consumers both under and over 4 years of age were significantly more likely to reach the RNI for calcium (P < 0.00005 and P < 0.05). Conclusions Preschool children's drinking has an impact on their intakes of vitamin C, iron and calcium. In particular, intakes of calcium are closely linked to the amount of milk consumed in this age group. [source]


Evidence of high sugar intake, and low fibre and mineral intake, in the gluten-free diet

Aliment Pharmacol Ther 2010; 32: 573,581 Summary Background, The only therapy for coeliac disease (CD) is a long-term gluten-free diet (GFD). Little is known about the detailed composition of such a diet. Aim, To clarify the nutritional composition of a GFD and to compare it with a non-GFD diet in representative non-CD populations. Methods, A total of 139 consecutive patients with CD were invited to fill in a prospective validated 5-day food diary, of whom data from 93 were analysed. Results were compared with data from the National Diet and Nutrition Survey of Adults and the UK Women's Cohort Study (UKWCS). Results, Individuals consuming a strict GFD generally had similar intakes of energy and nutrients to those of comparison populations, but a higher proportion of carbohydrate intake was obtained from nonmilk extrinsic sugars and intakes of nonstarch polysaccharides were low. Compared with the UKWCS sample, female patients adhering to a GFD had lower intakes of magnesium, iron, zinc, manganese, selenium and folate. In male patients, intakes of magnesium and selenium were particularly low. Conclusions, This study reinforces the need for clinicians to recognize that avoidance of gluten cannot be the sole focus of a gluten-free diet. Maintenance of adequate intakes of essential nutrients and in particular complex carbohydrates must also be the goal for patients. [source]
