To investigate whether supplement dietary fibre improves compliance to very low calorie diets (VLCD), a nutritional powder providing 388 kcal/day was compared with a similar preparation containing 30 plant fibre per day. Twenty-two obese patients participated in the study. After three days on their habitual diet they were allocated at random according to a single blind design to VLCD either with or without dietary fibre for two weeks. Thereafter, they were crossed over to the other form of diet for two further weeks. All of the patients completed the study. Both of the groups had considerable weight losses which were similar (about 10 kg/4 weeks) and dietary fibre did not improve the result further. During the period with VLCD with fibre, hunger ratings were significantly lower than on diets with VLCD without fibre (fibre effect p less than 0.01). Bowel movements decreased from 1.9 per day on the habitual diet to 0.7 per day on VLCD without fibre but increased to 1.0 per day with the fibre supplement (fibre effect p less than 0.01). No differences were found between the effects of the two types of diet on satiety, consistency of the faeces and flatulence. The supplement of dietary fibre did not influence plasma concentrations of divalent cations such as calcium, iron or magnesium nor did it contribute to the lowering effect of VLCD on plasma glucose, cholesterol or triglyceride. It is concluded that supplementation of VLCD with dietary fibre may improve compliance by normalising hunger and increasing the number of bowel movements without impairing the absorption of divalent cations.

To examine whether supplement of dietary fibre may improve compliance to a very low calorie diet (VLCD) a nutrition powder providing 388 kcal/day (men: 466 kcal/day) was compared with a similar version containing plant fibre 30 g/day. Twenty-two obese patients entered the study. After a baseline habitual diet, they were randomized to two weeks of treatment in a single blind design to either VLCD with or without dietary fibre. Subsequently, they were crossed over for further 2 weeks of treatment. All patients completed the study. The two groups had similar weight losses (about 10 kg/4 weeks), and dietary fibre did not improve this result. During VLCD with fibre hunger ratings were significantly lower than during VLCD without fibre (fibre effect, ANOVA; P less than 0.01). Bowel movements decreased from 1.9/day on habitual diet to 0.7/day on VLCD without fibre, but increased to 1.0/day by fibre supplement (fibre effect, P less than 0.01). No effect of fibre supplementation to VLCD was found on satiety, consistency of faeces and flatulence. The supplement of dietary fibre did not influence plasma concentrations of divalent cations as calcium, iron or magnesium, nor did it add any lowering effect on plasma glucose, cholesterol or triglyceride to that of VLCD. In conclusion, the supplement of dietary fibre to VLCD may improve compliance by reducing hunger and increasing the number of bowel movements, without impairment of absorption of divalent cations.

An analysis conducted by WHO in 1991 and 1992 indicated that death rates from diseases related to diet and life-style (heart conditions, cancer, and diabetes) have increased significantly in many countries during the past 30 years, largely owing to changes in diet and life-style. 40 high-income countries have diet-related disorders, and as many as 80 middle-income nations may have both undernutrition and overnutrition problems. Undernutrition is widespread in some 50 low-income countries and is associated with a high incidence of stunting and micronutrient deficiencies (especially iron, iodine, and vitamin A). Diet-related deficiencies affect 2000 million people. WHO scientists reviewed data from 26 developed and 16 developing countries from the period 1960-89: 20 countries showed increases ranging up to 160% in death rates from diet-related and life-style-related causes. The biggest decreases were in Australia, Canada, Japan, and the USA where education advised people to limit intakes of fat, saturated fat, and salt as well as to increase exercise and reduce smoking. Data on food availability for 1988-90 showed that an estimated 786 million people in developing countries were chronically undernourished. Hunger and malnutrition affect many of the 123 million people living in 11 countries where the food situation is critical. Some 192 million children 5 years of age suffer from protein-energy malnutrition characterized by retardation of physical growth and lowered resistance to infections. 55 million of these underweight children are in south Asian countries. In these countries, about half of all deaths occur before 5 years of age, and the majority of these deaths are caused by diarrheal disease. It is estimated that up to 70% of diarrhea cases are food-borne in origin. There are 1500 million episodes of diarrhea annually in children 5 years of age, killing 3 million of them.

Dietary prescriptions meant to reduce the risk of adult diseases could retard growth and development in infants and young children. Parents who pay attention to their infant's hunger or satiety signals will avoid under-feeding or over-feeding their infant. A useful guiding principle is that, as long as overall growth compares favourably with the standards for age, it is likely that all is well. Nutrition priorities during infancy should reflect the promotion of growth and development rather than the prevention of diseases later in life. For this reason, fat restriction is not appropriate under 2 years of age. Don't overdo high-fibre foods. The decrease in iron deficiency anaemia in infants is probably due to the increased use of iron-fortified milk formulae and breakfast cereals. Children up to the age of 5 years need to consume foods which give them sufficient energy and nutrients. Above all, extreme dietary practices should be avoided.

A study of food insecurity and nutritional adequacy was conducted with a sample of 153 women in families receiving emergency food assistance in Toronto, Canada. Contemporaneous data on dietary intake and household food security over the past 30 d were available for 145 of the women. Analyses of these data revealed that women who reported hunger in their households during the past 30 d also reported systematically lower intakes of energy and a number of nutrients. The effect of household-level hunger on intake persisted even when other economic, socio-cultural, and behavioral influences on reported dietary intake were considered. Estimated prevalences of inadequacy in excess of 15% were noted for Vitamin A, folate, iron, and magnesium in this sample, suggesting that the low levels of intake associated with severe household food insecurity are in a range that could put women at risk of nutrient deficiencies.

The prevalence of anemia is high in adolescent girls in India, with over 70% anemic. Iron-folic acid (IFA) supplements have been shown to enhance adolescent growth elsewhere in the world. To confirm these results in India, a study was conducted in urban areas of Vadodora, India to investigate the effect of IFA supplements on hemoglobin, hunger and growth in adolescent girls 10-18 y of age. Results show that there was a high demand for IFA supplements and >90% of the girls consumed 85 out of 90 tablets provided. There was an increment of 17.3 g/L hemoglobin in the group of girls receiving IFA supplements, whereas hemoglobin decreased slightly in girls in the control group. Girls and parents reported that girls increased their food intake. A significant weight gain of 0.83 kg was seen in the intervention group, whereas girls in the control group showed little weight gain. The growth increment was greater in the 10- to 14-y-old age group than in the 15- to 18-y-old group, as expected, due to rapid growth during the adolescent spurt. IFA supplementation is recommended for growth promotion among adolescents who are underweight.

BACKGROUND: vertical banded gastroplasty (VBG) and gastric bypass Roux-en-Y (GBP) are adjunctive to lifelong commitment to energy restricted diet in the attempt by the severely obese to lose weight and maintain weight loss. METHODS: the outcome of 48 subjects (36 VBG and 12 GBP) is presented. RESULTS: 18 months nutritional counseling and follow-up indicated VBG and GBP to be equally effective in maintaining appreciable weight loss. Achievement of 'functional weight', such as minimum 50% loss of excess body weight for at least 12 months Post-operatively occurred in the majority of patients. Excess weight loss by GBP and VBG was 77% and 54% respectively during the first 6 months, with 7-15% additional loss during the next 12 months. BMI decreased from an average 43 to 27 kg m(2) after 12 months. During the first 3 months, energy intake was approximately 2930 kJ, increasing to;4605 kJ at 6 months, to; 5860 kJ at 12 months and then stabilizing. Intake of;50% of the Recommended Daily Allowance (RDA) for most vitamins and minerals was reached. Hemoglobin, iron, folic acid and thiamin values were in the normal range for the entire 18 months follow-up, while serum vitamin B12 levels decreased to deficiency levels during the same period. The pre-operative moderately elevated triglycerides, cholesterol, glucose and insulin levels returned to normal range, thereby alleviating the need for medication and reducing the risk of obesity-related morbidity. Most subjects were quickly satiated with small amounts of solid foods and did not report hunger feelings for the first 6 months post-operatively. The main significant changes in food preferences in the first 6 months were the decrease in starch-based products and the increase in semi-solid milk products and eggs. CONCLUSION: taken together these observations suggest that the subjects should be strongly advised to partake in structured counseling for an extended period of time.

There have been many remarkable advances in pediatric nutrition. Solid scientific evidence now supports certain fundamental assumptions long held in the pediatric community. For example, obesity in children has for some time been believed to have adverse health effects; recent large scale studies now confirm relationships between childhood obesity and specific morbidities. Likewise, the beneficial effects of human breast milk on growth and development have been the focus of recent prospective studies of full term and preterm infants. There has been active research in the area of formula intolerance and allergy, allowing practicing physicians to better counsel parents about dietary choices. Although many health problems are caused by the abundance of high fat and high calorie foods in the average US child's diet, a large number of children remain at risk for hunger in the United States. Other research provides important breakthroughs in our understanding of the impact of pediatric nutrition on lifelong health. Retrospective epidemiological studies have uncovered relationships between prenatal factors and health later in life. These studies have lead to ongoing prospective observational trials that should provide further information about the extent to which certain health factors are determined before birth. In addition, basic science research has revealed previously unknown mechanisms by which essential minerals, such as iron, are transported into the body. In sum, this section reviews exciting new information in the areas of childhood diet quality, obesity, breast milk, formula intolerance, and iron metabolism.

The goal of the present study was to examine the association of the Food Stamp Program with the food security and dietary intake of low-income children from Hartford, CT, who were enrolled in the Supplemental Food Program for Women, Infants, and Children (WIC). We compared the food and nutrition situation of low-income preschoolers who received food stamps (FS, n = 59) with that of those who did not receive food stamps (NFS, n = 40). Children were an average age of 2.7 +/- 0.6 y, and 95% were receiving WIC benefits at the time of the study. Groups were comparable in demographic characteristics, but the socioeconomic status of the FS group was lower than that of the NFS group (P < 0.05). Food security was assessed with the Radimer/Cornell hunger scale, and dietary intake was assessed with a single 24-h recall and a 14-item food frequency questionnaire. Multivariate analyses within the FS group indicated that a monthly duration of food stamps of <4 wk was a predictor of household food security (odds ratio 0.10, 95% confidence interval 0.02-0.56). Food stamp use was associated with above-median energy-adjusted intakes of vitamin B-6 (3.13, 1.16-8.45), folate (2.92, 1.09-7.81) and iron (3.72, 1.31-10.54). The NFS children were more likely to consume <8 mg iron/d (3.73, 1.09-12.80). These results suggest that the Food Stamp Program is associated with food security and preschoolers' micronutrient intake.

Achievement of Health-for-All, whereby people everywhere throughout their lives, have the opportunity to reach and maintain the highest attainable level of health is impossible whilst hunger, starvation, and malnutrition remain. Malnutrition covers a broad spectrum of ills, including undernutrition, specific nutrient deficiencies, and overnutrition; and it kills, maims, retards, cripples, blinds, and impairs human development on a truly massive scale worldwide. In the developing world in 1995, of the estimated 10.4 million deaths among children under 5 years of age, protein-energy malnutrition was an associated and causative factor in 5.1 million of these deaths (i.e. 49%). On the other hand, evidence has recently been compiled suggesting that of the more than 10 million cases of cancer that occurred in 1996, an estimated 30-40% (3-4 million every year) are preventable by feasible, appropriate diets, and by physical activity and maintenance of appropriate body weight. Malnutrition affects all age groups across the entire lifespan. From the moment of conception, throughout foetal life, iodine, folate and intrauterine nutrition have a profound influence on development, growth, morbidity, mortality, not only in utero and in early infancy, but on morbidity, physical and mental capacity throughout life. Despite significant improvements in world food supplies, health conditions, and availability of educational and social services, no population escapes malnutrition's grasp. All countries have significant population groups with some form of debilitating malnutrition. Malnutrition worldwide, includes a spectrum of nutrient-related disorders, deficiencies and conditions including the following major public health problems; Intrauterine growth retardation, protein-energy malnutrition, Iodine deficiency disorders, Vitamin A Deficiency, Iron Deficiency Anaemia and Overweight and Obesity (WHO, Website).
