Abstract
Abstract. Objectives: Food-based strategies remain the most sustainable solutions for combating micronutrient deficiencies. Crude palm oil being the richest natural source of β-carotene, the study aimed to assess the impact of crude palm oil fortified cookies supplementation on anthropometry, vitamin A and hematological status of school children. Methods: 444 children (boys-226, girls-218), aged 5-13 years from two Municipal Corporation of Delhi primary schools were enrolled. By draw of lot, children from one of the schools formed the experimental (n = 224; boys-119, girls-105) while other formed the placebo group (n = 220; boys-107; girls-113). Children from the experimental group received six crude palm oil fortified cookies providing 2152 μg of β-carotene while the placebo group received similar but non-fortified cookies each day for 50 school days. Anthropometry, vitamin A, and hematological status were assessed at baseline and post supplementation. Results: Post supplementation, the number of stunted subjects reduced significantly (p < 0.05) in the experimental group. There was a significant increase in plasma retinol (170.9%; mean change: 1.55 ± 1.30 μmol/L - experimental group vs. 0.45 ± 0.99 μmol/L - placebo group) and β-carotene (p < 0.01; median change from 0.55 to 0.76 μmol/L - experimental group vs. 0.59 to 0.55 μmol/L -placebo group) concentrations of the experimental group. The increase in hematological parameters (mean change in Hemoglobin: 1.64 g/dL in experimental group vs. 2.10 g/dL in placebo group) of both the groups were however, comparable. Conclusion: To address micronutrient deficiencies particularly in developing nations, the use of crude palm oil should be encouraged through supplementary feeding programs by way of ready-to-eat snacks.

Abstract
BACKGROUND/OBJECTIVES The consumption of antioxidant-rich cooking oil such as red palm olein may be cardioprotective from the perspective of subclinical inflammation and endothelial function. SUBJECTS/METHODS Using a crossover design, we conducted a randomised controlled trial in 53 free-living high-risk abdominally overweight subjects, comparing the effects of incorporating red palm olein (with palm olein as control) in a supervised isocaloric 2100 kcal diet of 30% en fat, two-thirds (45 g/day) of which were derived from the test oil for a period of 6 weeks each. RESULTS We did not observe a significant change in interleukin-6 (IL-6), in parallel with other pro-inflammatory (tumour necrosis factor-β, interleukin-1β, IL-1β, high sensitivity C-reactive protein, hsCRP) and endothelial function (soluble intercellular adhesion molecules, sICAM, soluble intravascular adhesion molecules, sVCAM) parameters. Interestingly, we observed a significant reduction in oxidised LDL levels (P < 0.0386) while on the red palm olein diet, together with the increase in plasma alpha tocopherol (P < 0.0002), alpha carotene (P < 0.0001) and beta carotene (P < 0.0001) concentrations compared with palm olein diet. CONCLUSION Red palm olein did not improve subclinical inflammation and endothelial function despite profound increase in antioxidant levels. The positive improvement in oxidised LDL merits further attention in this group of subjects at risk of developing cardiovascular disease.

Abstract
The fruit of the oil palm tree (Elaeis guineesis) is the source of antioxidant-rich red palm oil. Red palm oil is a rich source of phytonutrients such as tocotrienols, tocopherols, carotenoids, phytosterols, squalene, and coenzyme Q10, all of which exhibit nutritional properties and oxidative stability. Mutagenic, nutritional, and toxicological studies have shown that red palm oil contains highly bioavailable β-carotene and vitamin A and is reasonably stable to heat without any adverse effects. This review provides a comprehensive overview of the nutritional properties of red palm oil. The possible antiatherogenic, antihemorrhagic, antihypertensive, anticancer, and anti-infective properties of red palm oil are examined. Moreover, evidence supporting the potential effectiveness of red palm oil to overcome vitamin A deficiency in children and pregnant women, to improve ocular complications of vitamin A deficiency, to protect against ischemic heart disease, to promote normal reproduction in males and females, to aid in the management of diabetes, to ameliorate the adverse effects of chemotherapy, and to aid in managing hypobaric conditions is presented.

Abstract
In an effort to control the high prevalence of vitamin A deficiency in Ghana, which studies have shown to be of public health significance, a number of interventions are being pursued. Periodic, massive-dose supplementation strategy, developed as a short-term life-saving intervention, is currently under way, either as part of the polio eradication program or combined with the existing health delivery system, schools, or community-based infrastructures. This has been successfully accomplished, and therefore the stage is set for the design and implementation of a long-term, sustainable solution. This is important in order to make the transition from a subsidized periodic capsule-distribution effort to a more sustainable food-based intervention, which could supply other vital nutrients as well as vitamin A in the diet. This report describes a proposal for a food-based strategy against a backdrop of low consumption in spite of the relatively high availability of some vitamin A–rich foods in most parts of Ghana. The aim is to improve vitamin A status of vulnerable groups through increased production, availability, and consumption of vitamin A–rich foods. The proposal is therefore to undertake a range of food-based interventions that will include horticultural interventions that aim to increase production and availability of vitamin A–rich foods, such as dark-green leafy vegetables and orange-colored fruits and vegetables and tubers in the diet of Ghanaian households. There will also be a comprehensive behavior change and communication strategy, to raise awareness of the causes and consequences of vitamin A deficiency and the need for consumption of adequate vitamin A–rich foods at the household level. Further emphasis will be placed on efforts to promote consumption of red palm oil, since this oil is generally available and not subjected to acute seasonal shortages. A phased community-based program will be implemented in four districts during the next three years, with the aim of applying lessons learned to the rest of the country. The monitoring framework will cover the planning process, provision of services, utilization of services, and coverage of target groups. These dietary approaches offer long-term sustainable options for improving the quality of family diets and overcoming vitamin A deficiency.

Abstract
This review article points out that bananas are an important food for many people in the world. Thus, banana cultivars rich in provitamin A carotenoids may offer a potential food source for alleviating vitamin A deficiency, particularly in developing countries. Many factors are associated with the presently known food sources of vitamin A that limit their effectiveness in improving vitamin A status. Acceptable carotenoid-rich banana cultivars have been identified in Micronesia, and some carotenoid-rich bananas have been identified elsewhere. Bananas are an ideal food for young children and families for many regions of the world, because of their sweetness, texture, portion size, familiarity, availability, convenience, versatility, and cost. Foods containing high levels of carotenoids have been shown to protect against chronic disease, including certain cancers, cardiovascular disease, and diabetes. Because the coloration of the edible flesh of the banana appears to be a good indicator of likely carotenoid content, it may be possible to develop a simple method for selecting carotenoid-rich banana cultivars in the community. Research is needed on the identification of carotenoid-rich cultivars, targeting those areas of the world where bananas are a major staple food; investigating factors affecting production, consumption, and acceptability; and determining the impact that carotenoid-rich bananas may have on improving vitamin A status. Based on these results, interventions should be undertaken for initiating or increasing homestead and commercial production.

Abstract
This double-blinded, randomized, controlled study was designed to study the effect of dietary supplementation with red palm oil during pregnancy on maternal and neonatal vitamin A status. A total of 170 women were recruited at 16 to 24 weeks of gestation and randomly assigned to an experimental group that received red palm oil to supply approximately one recommended dietary amount (RDA) (2,400 μg) of β-carotene or to a control group that received an equivalent volume of groundnut oil. The women received the oils for a period of 8 weeks, starting at 26 to 28 weeks of gestation and extending to 34 to 36 weeks of gestation. The mean postintervention (34 to 36 weeks) levels of serum retinol were 1.20 ± 0.22 (SD) μmol/L (95% CI, 1.15–1.25) in women receiving red palm oil and 0.73 ± 0.15 μmol/L (95% CI, 0.69–0.77) in their infants; these levels were significantly higher than those in women receiving groundnut oil (1.07 ± 0.26 μmol/L; 95% CI, 1.01–1.13; p < .01) and their infants (0. 62 ± 0.17 μmol/L; 95% CI, 0.57–0.67; p < .001). A significantly lower proportion of women in the red palm oil group than in the control group had vitamin A deficiency (serum retinol levels < 0.7 μmol/L) after intervention (1.5% vs. 9.7%). The proportion of women having anemia was significantly lower (p < .01) in the red palm oil-supplemented group (80.6%) than in the control group (96.7%). The mean birthweight and gestational age of the infants did not differ significantly between the two groups. An increased risk of low birthweight (p = . 003) and preterm delivery (p = . 000) was observed with decreasing serum retinol levels in the third trimester of pregnancy. These results show that red palm oil supplementation significantly improved maternal and neonatal vitamin A status and reduced the prevalence of maternal anemia. Maternal vitamin A status in the later part of pregnancy is significantly associated with fetal growth and maturation. Hence red palm oil, a rich source of bioavailable vitamin A, could be used as a diet-based approach for improving vitamin A status in pregnancy.

Abstract
Cake rusks were prepared by using different combinations of normal and red palm oil fortified shortening to explore the possibility of red palm oil (RPO) fortified shortening to enhance the vitamin A status in human dietary intake. The replacement of normal shortening with RPO up to 50% level was the most acceptable, however, the use of RPO shortening beyond this limit showed a somewhat oily after taste. Carotenoid contents in flour, normal shortening, RPO shortening and egg were 3.57 ppm, 5.85ppm, 405.39 ppm and 5.13 ppm, respectively. Moisture content increased from 3.11% to 3.22% after 28 days of storage. During baking, loss of carotenoid contents ranged from 12.07% to 14.91%. A minimum carotenoid content of 7.19 ppm were found in the cake rusks (T1) prepared with 100% normal shortening (NS) while a maximum of 105.64 ppm was observed in (T5) 100% RPO in the freshly prepared product. The mean carotenoid content in T3 (50% RPO 50% NS) was 57.80ppm however it ranged from 6.94ppm (T1) to 102.34 ppm in (T5). A gradual decrease (7–10%) in carotenoid contents during 28 days’ storage was observed. There was significant increase (0.04–0.08 mg malonaldehyde/kg) in thiobarbituric acid number during storage. Results regarding sensory attributes reflect that T3 comprising of 50% RPO and 50% NS got the highest score. Furthermore consumer response in the acceptability study also showed that T3 treatment of cake rusk is suitable for commercialisation.

Abstract
Palm oil is the major oil produced, with annual world production in excess of 50 million tonnes. About 85% of global palm oil produced is used in food applications. Over the past three decades, research on nutritional benefits of palm oil have demonstrated the nutritional adequacy of palm oil and its products, and have resulted in transitions in the understanding these attributes. Numerous studies have demonstrated that palm oil was similar to unsaturated oils with regards to effects on blood lipids. Palm oil provides a healthy alternative to trans-fatty acid containing hydrogenated fats that have been demonstrated to have serious deleterious effects on health. The similar effects of palm oil on blood lipids, comparable to other vegetable oils could very well be due to the structure of the major triglycerides in palm oil, which has an unsaturated fatty acid in the stereospecific numbers (sn)-2 position of the glycerol backbone. In addition, palm oil is well endowed with a bouquet of phytonutrients beneficial to health, such as tocotrienols, carotenoids, and phytosterols. This review will provide an overview of studies that have established palm oil as a balanced and nutritious oil.

Abstract
Background The World Health Organization (WHO) classifies Guinea-Bissau as having severe vitamin A deficiency (VAD). To date, no national survey has been conducted. We assessed vitamin A status among children in rural Guinea-Bissau to assess status and identify risk factors for VAD. Methods In a vitamin A supplementation trial in rural Guinea-Bissau, children aged 6 months to 2 years who were missing one or more vaccines were enrolled, vaccinated and randomized to vitamin A or placebo. Provided consent, a dried blood spot (DBS) sample was obtained from a subgroup of participants prior to supplementation. Vitamin A status and current infection was assessed by an ELISA measuring retinol-binding protein (RBP) and C-reactive protein (CRP). VAD was defined as RBP concentrations equivalent to plasma retinol <0.7 μmol/L; infection was defined as CRP >5 ml/L. In Poisson regression models providing prevalence ratios (PR), we investigated putative risk factors for VAD including sex, age, child factors, maternal factors, season (rainy: June-November; dry: December-May), geography, and use of health services. Results Based on DBS from 1102 children, the VAD prevalence was 65.7% (95% confidence interval 62.9-68.5), 11% higher than the WHO estimate of 54.7% (9.9-93.0). If children with infection were excluded, the prevalence was 60.2% (56.7-63.7). In the age group 9–11 months, there was no difference in prevalence of VAD among children who had received previous vaccines in a timely fashion and those who had not. Controlled for infection and other determinants of VAD, the prevalence of VAD was 1.64 (1.49-1.81) times higher in the rainy season compared to the dry, and varied up to 2-fold between ethnic groups and regions. Compared with having an inactivated vaccine as the most recent vaccine, having a live vaccine as the most recent vaccination was associated with lower prevalence of VAD (PR=0.84 (0.74-0.96)). Conclusions The prevalence of VAD was high in rural Guinea-Bissau. VAD varied significantly with season, ethnicity, region, and vaccination status. Trial registration Clinicaltrials.gov NCT00514891

Abstract
Vitamin A deficiency is one of the most widespread nutritional deficiencies worldwide. Hundreds of millions of children and tens of millions of women living in Sub-Saharan Africa and Southeast Asia are at particularly high risk of the adverse health consequences associated with this largely preventable condition. Red palm oil comes from oil palms that are traditionally grown in tropical regions of West Africa and are now cultivated on a large-scale commercial basis in Southeast Asia. Red palm oil is the richest naturally occurring source of beta-carotene, a carotenoid that the human body can convert into usable vitamin A (retinol). This paper reviews a series of key intervention studies designed to investigate the impact of using red palm oil-based interventions to improve vitamin A status. These included studies from Africa, Asia, and Latin America in which red palm oil was used (or proposed for use) (1) as a dietary supplement, (2) as an in-home fortificant, (3) to fortify foods used for distribution in targeted supplementary feeding programs, and (4) to fortify staple food products. Overall, the results suggest that red palm oil is highly efficacious in improving vitamin A status among populations at risk of vitamin A deficiency. The time has come to move beyond trials of biological efficacy and focus on conducting operational research projects, effectiveness trials, and cost-benefit analyses that will help expand the use of red palm oil in areas where it is likely to be well accepted but remains underutilized as a dietary source of provitamin A.

Abstract
Prophylactic doses of 120 mg of iron (Fe) are commonly used to prevent Fe-deficiency anemia in vulnerable populations, especially in developing countries. Evidence shows that residual Fe in the large bowel may alter the normal antioxidant capacity of the fecal stream. Our objective was to evaluate the effect of dietary antioxidants from the Carotino Tocotrienol-Carotene Mixed Concentrate (CTCMC) on the depletion of fecal antioxidant capacity by oral Fe supplementation. In total, 17 healthy male adults participated in the 2 phases of the study, 5 in the pilot study and 12 in the definitive intervention trial. Participants received different treatments, separated by washout periods. These included: 120 mg Fe; 120 mg Fe and refined palm oil (FeOil); and 120 mg Fe in refined palm oil combined with 1 of 2 dosages (0.4 g and 0.8 g) of CTCMC/5 mL of refined palm oil (CTCB and CTCA treatments, respectively). Fecal samples were collected and analyzed to quantify the products of hydroxyl radical attack on salicylic acid (2,5 dihydroxybenzoic acid, 2,3-dihydrobenzoic acid, and catechol) at baseline and after active supplementation. Fe supplementation in either form (Fe or FeOil treatments) increased the concentrations of hydroxylated compounds in fecal samples. The production of hydroxylated compounds was significantly lower in treatments CTCB and CTCA than in the FeOil reference. Baseline antioxidant capacity state was virtually restored with dietary carotenoids and tocotrienols from the CTCMC. In conclusion, dietary antioxidants can reverse the depletion of fecal antioxidant capacity induced by oral Fe supplements.

Abstract
Recent recommendations on feeding malnourished children do not provide indication on the nature of dietary lipids. Our aim was to compare the effect of palm oil (mainly saturated and monounsaturated fatty acids) and soybean oil (mainly polyunsaturated fatty acids) on the recovery from malnutrition in guinea pigs. In a first experiment, guinea pigs received a balanced (control group) or a maize (malnourished group) diet for 7, 12, and 21 d. In a second experiment, after 12 d of malnutrition, guinea pigs received a rehabilitation diet containing palm or soybean oil. Both rehabilitation diets allowed a partial recovery from the severe weight loss induced by malnutrition. Thiobarbituric acid reactive substances content, measured in intestinal homogenates, increased in malnourished guinea pigs compared with control animals (40%, p < 0.05) and returned to near control values after rehabilitation with palm (10%) but not soybean (43%) oil diet. Intestinal short-circuit current, assessed in jejunal segments mounted in Ussing chambers, increased progressively during malnutrition (p < 0.001) and returned to near control values with both rehabilitation diets. Compared with control animals, the cell turnover (Ki-67 index assessed by immunohistochemistry detection of the Ki-67 antigen) decreased after soybean (-60%, p < 0.01) but not after palm oil. These results confirm that experimental polydeficient malnutrition induces oxidative stress and dysfunction in the intestine. They show a differential effect of palm and soybean oil on these intestinal measurements, suggesting that the composition of dietary lipids may be important in the treatment of malnutrition.

Abstract
Palm oil is an excellent choice for food manufacturers because of its nutritional benefits and versatility. The oil is highly structured to contain predominantly oleic acid at the sn2-position in the major triacylglycerols to account for the beneficial effects described in numerous nutritional studies. Oil quality and nutritional benefits have been assured for the variety of foods that can be manufactured from the oil directly or from blends with other oils while remaining trans-free. The oxidative stability coupled with the cost-effectiveness is unparalleled among cholesterol-free oils, and these values can be extended to blends of polyunsaturated oils to provide long shelf-life. Presently the supply of genetic-modification-free palm oil is assured at economic prices, since the oil palm is a perennial crop with unparalleled productivity. Numerous studies have confirmed the nutritional value of palm oil as a result of the high monounsaturation at the crucial 2-position of the oil's triacylglycerols, making the oil as healthful as olive oil. It is now recognized that the contribution of dietary fats to blood lipids and cholesterol modulation is a consequence of the digestion, absorption, and metabolism of the fats. Lipolytic hydrolysis of palm oil glycerides containing predominantly oleic acid at the 2 position and palmitic and stearic acids at the 1 and 3 positions allows for the ready absorption of the 2-monoacrylglycerols while the saturated free fatty acids remain poorly absorbed. Dietary palm oil in balanced diets generally reduced blood cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides while raising the high-density lipoprotein (HDL) cholesterol. Improved lipoprotein(a) and apo-A1 levels were also demonstrated from palm oil diets; an important benefits also comes from the lowering of blood triglycerides (or reduced fat storage) as compared with those from polyunsaturated fat diets. Virgin palm oil also provides carotenes apart from tocotrienols and tocopherols that have been shown to be powerful antioxidants and potential mediators of cellular functions. These compounds can be antithrombotic, cause an increase of the prostacyclin/thromboxane ratio, reduce restenosis, and inhibit HMG-CoA-reductase (thus reducing) cholesterol biosynthesis). Red palm oil is a rich source of beta-carotene as well as of alpha-tocopherol and tocotrienols.
