The Food and Nutrition Board of the National Research Council has recently revised and extended its list of recommended dietary allowances, RDA, for individuals in the US, in view of new nutritional knowledge and the uses to which these RDA are put. In addition to being guides to human needs for nutrients, the RDA have become guides for regulatory agencies that are responsible for nutrition labelling, for regulations designed to ensure nutritional quality of foods and for development of new food products.

Encouraging socio‐economic development in developing countries has resulted in many changes in the lifestyle of communities. Changes in dietary patterns are one of the main outcomes from the rapid socio‐economics advancement, for example excessive intake of fat, high‐protein diet (animal protein), salt and preservatives. Chronic diseases such as diabetes, coronary artery disease, hypertension and cancer are mostly related to diet. With the community becoming more nutrition and health conscious, one of the challenges faced is to make sure that the information and knowledge on diet and healthy lifestyle gets across to the community. This paper presents a model of web‐based diet system (WebDIET) that attempts to make diet information and menu plans that are customised to local preference more accessible via the use of Internet. The system is to be used by dieticians who serve as administrators and the public who are the end users. The dietary standard adapted in developing the system is Recommended Dietary Allowances (RDA) for Malaysia. The Malaysian Dietary Guidelines was also referred as it emphasises on Malaysian diet. The system consists of six modules namely Authentication Module, Menu Plan Module, Diabetic Menu Plan Module, Food Selection Module, Disease Info Module and Feedback Module. Diabetic menu plan module models the reasoning process employed by dieticians in suggesting menu plans. The planning task is solved using an artificial intelligence technique through the case‐based reasoning (CBR) approach. CBR, generally describes, the process of solving the current problem based on the proposed solution of similar problems in the past. Nearest Neighbour Algorithm was used to compute the similarities in weighted average. Tools used for the development of the system are Microsoft Visual Interdev, Microsoft FrontPage 2000, while HTML, VBScript and JavaScript are the scripting languages used to develop the system.

The purpose of the study was to assess the nutritional and health status of Saharia and non-Saharia women.

The present study was undertaken to compare the nutritional status of Saharia versus non-Saharia women in Baran district, Rajasthan. The sample comprised married non-pregnant and non-lactating (NPNL) women (aged 18-35 years) from three groups, that is, Saharia (n = 100), non-Saharia (Meena tribe, n = 100) and general category (n = 30). The general category women, or reference group, were selected as the control group belonging to the same region. The data included general profile, physical measurement, biochemical hemoglobin estimation, dietary and nutrient intake assessment.

The mean hemoglobin value in Saharia (8.3 ± 1.4 g/dl) and Meena (8.1 ± 1.4 g/dl) women was found to be significantly lower (p < 0.01 at 99 per cent confidence level) than that of the reference group (9.5 ± 1.4 g/dl) and much below the standard value of 12 g/dl. Chronic energy deficiency (BMI < 18.5) was more prevalent in Saharia women (68 per cent) followed by Meena (∼24 per cent) than reference women (7 per cent). Only 29 per cent Saharia women were under normal BMI and majority of the reference group women (77 per cent) and Meena women (72 per cent) had normal BMI (18.5-24). Nutrient and dietary intake of both the tribal women groups were low when compared with suggested levels. In Saharia and Meena women, magnesium and thiamine were significantly higher (p < 0.01) and other nutrients were significantly lower (p < 0.01) than recommended dietary allowances.

Anemia is prevalent in all categories of women. Women’s health is poor especially among Saharia women who are still striving hard to meet the national health standards. A multidimensional approach is required to uplift the health status. Hemoglobin levels of all the women were found to be very low.

The purpose of this paper is to describe methodology and practices undertaken during a pilot study on food composition of Turkish traditional foods (TTF).

The pilot study was conducted under the European Food Information Resource Network (EuroFIR) Project for the systemic investigation of traditional foods. As a partner country of the EuroFIR, Turkey has selected five traditional foods, tarhana soup, yoğurtlu kebap (kebab with yoghurt), hamsi buğulama (anchovy stew), pastırma, and baklava. The traditional recipes of the selected foods were recorded by field studies. Nutritional composition of foods was determined by chemical analyses.

Information on the identification, sampling, sample handling, and analysis was collected for each of the selected foods. The food composition data were evaluated by using EuroFIR standards, and the recommended dietary allowances (RDA) for nutritents. Five TTF were meeting with various nutrient recommendations.

This pilot study on the systemic investigation of traditional foods would be an example for further traditional food studies in Turkey and would enable the generation of reliable, representative and sufficient quality data on TTF.

Pomegranate (Punica granatum L.) fruit is highly valued for its delicious edible arils and health benefits. In this study, a comparative study on elemental composition of seven pomegranate cultivars was determined in the fruit rind, mesocarp and arils.

The concentrations of major elements (N, P, K, Ca, Mg, S, Cl and Na) and trace elements (Mn, Fe, Cu, Zn, B, Ni, Co, Cr, Pb, Cd, Se, Al, As, Li, Sr, Ti and V) were determined using an inductively coupled plasma optical emission spectrometry (ICP‐OES) calibrated with different concentrations of standard solutions of the minerals.

The highest amounts of N, P, S and Cl were found in Bhagwa cultivar, while Arakta, Ruby and Wonderful had the highest amount of Mg, Ca, and Na, respectively. P, Fe, Zn, Ti, V were more in quantity in the edible portion, while the other mineral elements were in larger proportions or in some cases were only found (Co, Al, As) in the non‐edible fractions of fruit. Among the major mineral elements investigated, P had the highest covering of the RDA, ranging from 6.78 to 8.53 per cent contribution to the RDA, followed by K (4.530‐4.95 per cent RDA), S (1.25‐1.54 per cent RDA), Ca (1.04‐1.54 per cent RDA), Mg (4.33‐5.26 per cent RDA), and Na (0.15‐0.17 per cent RDA).

Knowledge of the relative contributions of mineral elements in the edible fruit part (arils) to RDA will assist in nutrition planning against mineral deficiency.

Pomegranate fruit contains edible and non‐edible portions, and this study provided the first detailed report on the distribution of a wide range of trace and major mineral elements in the three parts of the fruit. This study also showed that the edible portion (arils) of pomegranate fruit is a good dietary source of essential nutrients such as K, Ca, Mg, and Se, while the non‐edible parts may provide valuable sources of minerals for other food and bioprocess industries.

An adequate variety of food necessary to provide a proper nutritional balance has always been a topic of prime concern for social economists. Moral and political concern caused the initiation of a series of studies focusing on the magnitude and causes of undernutrition. This article addresses concerns about some economic and health consequences of undernutrition and discusses some adverse health effects that may be associated with improper food balances. Findings suggest that a high percentage of undernutrition in the USA is concentrated in areas where social and economic deprivation is most prevalent, and shows that a complex of factors in the culture of poverty appear to be linked to undernutrition and non‐organic retardation. Two farm work crews were tested over a year with the objective of gaining more information about their dietary habit and nutritional status. Dietary deficiencies expressed as Bitot Spots (27.7 per cent) Visible Caries or ulceration (21.6 per cent) were found consistently among workers in the study sample population. Using F statistics and controlling for sex, male workers were found to be more adversely affected by dietary deficiencies than female workers.

Malnutrition affects one out of every three individuals living in developing countries. This disturbing state of affairs causes untold suffering. Little attention has been paid to the general food consumption within households in the developing countries. This study therefore aims to focus on the food consumption of urban households in Osun State, Nigeria.

One‐hundred‐and‐fifty‐eight nuclear households were purposively selected, which contained an average of four to six household members. Structured interview Schedule was used to collect information on the socioeconomic characteristics of the respondents, while a chart designed to collect information on daily individual food intake was also used. Statistical techniques like frequency count and percentage were used in data quantification of socioeconomic characteristics, while food composition table was used to analyse the Recommended Dietary Allowance met by the respondents.Findings – The results indicated that the body mass index (BMI) of women between the age range of 21 and 40 was 17.89, which implied mild malnutrition, while women who are 40 years and above had BMI of 18.64 which was marginal, whereas, their male counterparts of the same age ranges were normal with BMI of 23.69 and 20.81, respectively. Other age groups in the households had relatively normal BMI.

The limitation of the research was that it only assessed nuclear households in urban areas. Future study could include extended and polygamous households in both urban and rural areas.

This research established the facts that women of reproductive age tend towards being malnourished as a result of inadequate nutrients intake and this could be corrected through effective nutrition education.

The association between nutrition and cognitive test performance among school children is limited in developing countries, including Ghana. This paper aims to investigate the relationship between nutrient intake and cognitive competence in the context of abstract reasoning among school-aged children in the Tamale Metropolis.

The present cross-sectional study recruited 596 children aged 9–13 years from government-owned and private primary schools in Tamale Metropolis. Dietary intake was assessed by using three-day repeated 24-hour recall. Cognition was assessed by the Raven’s Coloured Progressive Matrices (RCPM) test, made up of 36 questions and used as a continuous variable, whereby higher scores indicated better cognition.

The majority of the children did not meet the recommended dietary allowances for protein (55.5%) and fibre (94.0%) and estimated adequate requirement for energy (86.6%), folate (72.8%), vitamin E (90.6%) and zinc (74.8%). More girls (55.1%) performed poorly in the cognition test than the boys (45.7%) (p = 0.029). Between-subject effects determined using univariate and multivariate analyses indicated age (p = 0.002), dietary folate (p = 0.016), vitamin C intake (p = 0.011), combined age and dietary folate (p = 0.049) and combined age and dietary vitamin C (p = 0.022) significantly affected cognition scores. Girls had lower odds (AOR = 0.7, p = 0.021, 95%CI = 0.5–0.9) of scoring above the 50th percentile in cognition test than boys.

The current nutrient intakes of the children were inadequate. The children performed poorly in Raven’s cognition test of abstract reasoning, and this was associated with being a girl.

To the best of the authors’ knowledge, this study is the first to investigate nutrient intakes and RCPM test performance among children in Northern Ghana. Thus, the findings of the study provide relevant information needed by stakeholders to implement nutrition programs in basic schools, aimed at ensuring optimal nutrition achievement among school children for improved cognition.

Rice landraces are essential for supplying beneficial traits for developing improved rice varieties with better nutritional quality. Nevertheless, in a yield-driven environment, grain nutritional quality has been ignored especially that of rice landraces. Given this, the purpose of this study is to evaluate the content and nutritional variability of rice landraces from Manipur.

Thirty-three most popular rice landraces were collected as dry paddy samples from Manipur and transported to the National Institute of Nutrition, Hyderabad, by air. All the paddy samples were processed and analyzed for 35 nutrient parameters using standard methodologies.

The mean nutrient content of Nagaland brown rice was: protein 7.5 ± 0.8, fat 3.0 ± 0.3, TDF 5.5 ± 0.4 and ash 1.2 ± 0.2 g/100g. The range of water soluble-vitamin content in mg/100g, was 0.1–0.43 for Thiamine and for Niacin 2.1–3.5, while the content in µg/100g was 40–64 for Riboflavin, 0.5–3.9 for Pantothenic acid and 20–118 for Pyridoxine. A relatively large coefficient of variation was observed for iron (25%), manganese (28%), copper (32%), calcium (13%) and phosphorus (11%). Manipur rice landraces have significantly higher total dietary fiber and lower phytate contents than modern varieties. Milling led to steep losses of nutrients, and limiting to 5% milling substantially improves nutrient retention in milled rice.

Future nutrition interventions should use rice with superior nutrient quality to improve nutrient intakes. Manipur rice landraces conserved over generations can broaden the genetic base of breeding stocks especially in the face of climate change.

The paper presents comprehensive nutritional data of 33 rice landraces from the state of Manipur, India. The results indicate large nutrient variability even within these 33 rice landraces with important traits such as high total dietary fiber and low phytate contents. The study highlights the importance of conserving the existing rich genetic material of Manipur rice landraces to develop varieties that combine higher yields with stress tolerance and superior grain nutritional value to improve the food and nutrient security.

The purpose of this paper is to assess physical activity and nutrient intake and their association with obesity in apparently healthy middle-aged adults in Akuse, a rural community in the Eastern region of Ghana.

This cross-sectional study assessed demography and anthropometry, nutrient intakes using a 3-day repeated 24 h dietary recall and physical activity using the global physical activity questionnaire (GPAQ). Data were entered into Microsoft excel and analyzed with SPSS version 25.

There were 118 respondents (55 males, 46.6% and 63 females, 53.4%) in the study with mean age of 45.62 ± 6.88 years. About 90% of respondents were physically active based on WHO physical activity recommendation. Prevalence of overweight/obesity was higher among inactive participants compared to active participants and sitting/reclining hours was significantly (p-value = 0.042) associated positively with BMI after a bivariate correlation analysis, suggesting that physical activity plays a role in obesity. About one in five respondents were obese. Mean energy intake exceeded RDA for females. Sodium intake far exceeded RDA for both males and females, putting the population at potential risk of hypertension.

This study demonstrates the need for intensifying health education and other obesity prevention interventions to curb the rising obesity prevalence in rural communities.

The study revealed that overweight/ obesity in this rural community is higher than previously reported for rural Ghana.
