Project description:IntroductionIn 1996, the US Food and Drug Administration (FDA) mandated folic acid fortification for all enriched cereal grains. This resulted in a reduction of neural tube defect (NTD)-affected pregnancies. However, Hispanic women continued to be twice as likely to give birth to a child affected by NTD compared to non-Hispanic White women. Some hypotheses explaining this difference focus on cultural variation in dietary intake of cereal grains. In 2016, the FDA approved voluntary folic acid fortification for corn masa flour products to focus on the Hispanic diet staple. This study investigates rates of NTDs in predominantly Hispanic-populated zip codes before and after the voluntary fortification of corn masa flour with folic acid.MethodsNormal pregnancies and those complicated by NTDs between 1/1/2016 and 9/30/2020 were identified using ICD-9 and ICD-10 codes in an all-payor claims database. The post-fortification period began 12 months after the fortification recommendation. The US Census data was used to stratify pregnancies in predominantly Hispanic zip codes (≥ 75% of households) vs. non-Hispanic zip codes. The causal impact of the FDA's recommendation was assessed by means of a Bayesian structural time series model.ResultsA total of 2,584,366 pregnancies were identified among females aged 15-50 years. Of these, 365,983 took place in predominantly Hispanic zip codes. Mean quarterly NTDs per 100,000 pregnancies did not significantly differ between predominantly Hispanic zip codes and predominantly non-Hispanic zip codes pre-FDA recommendation (184.5 vs. 175.6; p = 0.427), nor post-recommendation (188.2 vs. 185.9; p = 0.713). Rates of NTDs predicted to occur if no FDA recommendation had been made were compared to the actual rate post-recommendation: no significant difference was observed in predominantly Hispanic zip codes (p = 0.245) or overall (p = 0.116).ConclusionsRates of neural tube defects were not significantly reduced in predominantly Hispanic zip codes following the 2016 FDA approval of voluntary folic acid fortification of corn masa flour. Further research and implementation of comprehensive approaches to advocacy, policy, and public health are necessary to decrease preventable congenital disease rates. Mandatory rather than voluntary fortification of corn masa flour products may achieve more substantial prevention of neural tube defects in at-risk US populations.

Project description:There is widespread vitamin and mineral deficiency problem in Tanzania with known deficiencies of at least vitamin A, iron, folate and zinc, resulting in lasting negative consequences especially on maternal health, cognitive development and thus the nation's economic potential. Folate deficiency is associated with significant adverse health effects among women of reproductive age, including a higher risk of neural tube defects. Several countries, including Tanzania, have implemented mandatory fortification of wheat and maize flour but evidence on the effectiveness of these programs in developing countries remains limited. We evaluated the effectiveness of Tanzania's food fortification program by examining folate levels for women of reproductive age, 18-49 years. A prospective cohort study with 600 non-pregnant women enrolled concurrent with the initiation of food fortification and followed up for 1 year thereafter. Blood samples, dietary intake and fortified foods consumption data were collected at baseline, and at 6 and 12 months. Plasma folate levels were determined using a competitive assay with folate binding protein. Using univariate and multivariate linear regression, we compared the change in plasma folate levels at six and twelve months of the program from baseline. We also assessed the relative risk of folate deficiency during follow-up using log-binomial regression. The mean (±SE) pre-fortification plasma folate level for the women was 5.44-ng/ml (±2.30) at baseline. These levels improved significantly at six months [difference: 4.57ng/ml (±2.89)] and 12 months [difference: 4.27ng/ml (±4.18)]. Based on plasma folate cut-off level of 4 ng/ml, the prevalence of folate deficiency was 26.9% at baseline, and 5% at twelve months. One ng/ml increase in plasma folate from baseline was associated with a 25% decreased risk of folate deficiency at 12 months [(RR = 0.75; 95% CI = 0.67-0.85, P<0.001]. In a setting where folate deficiency is high, food fortification program with folic acid resulted in significant improvements in folate status among women of reproductive age.

Project description:Surveillance data have highlighted continued disparities in neural tube defects (NTDs) by race-ethnicity in the United States. Starting in 2016, the Food and Drug Administration (FDA) authorized voluntary folic acid fortification of corn masa flour to reduce the risk of neural tube defects (NTDs) among infants of Hispanic women of reproductive age. To assess the impact of voluntary corn masa fortification, cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 for Hispanic women of reproductive age with available red blood cell (RBC) folate concentrations were analyzed, with additional analyses conducted among Hispanic women whose sole source of folic acid intake was fortified foods (enriched cereal grain products (ECGP) only), excluding ready-to-eat cereals and supplements. RBC folate concentration (adjusted geometric mean) among Hispanic women of reproductive age did not differ between 2011-2016 and 2017-2018, though RBC folate concentration increased significantly among lesser acculturated Hispanic women consuming ECGP only. Concentrations of RBC folate for those born outside the U.S and residing in the U.S <15 years increased from 894 nmol/L (95% CI: 844-946) in 2011-2016 to 1018 nmol/L (95% CI: 982-1162; p < 0.001) in 2017-2018. Primarily Spanish-speaking Hispanic women of reproductive age who only consumed ECGP saw an increase from 941 nmol/L (95% CI: 895-990) in 2011-2016 to 1034 nmol/L (95% CI: 966-1107; p = 0.03) in 2017-2018. By subpopulation, we observed no significant changes in the proportion at risk of NTDs (<748 nmol/L) and no changes in the model-based estimated NTD rates following voluntary corn masa fortification. This analysis suggests that there is a remaining risk among Hispanics for folate sensitive NTDs, though continued monitoring of folate status in future NHANES data cycles will help inform the long-term efficacy of voluntary fortification of corn masa flour.

Project description:ObjectiveFolic acid supplementation during the periconceptual period has been shown to improve cognitive outcomes in children of women with epilepsy taking anti-seizure medications (ASMs). The dose of folic acid necessary to provide positive cognitive outcomes is unclear. In many countries including the United States, food is fortified with folic acid, but no data exist on how food fortification may affect cognition in children with fetal-ASM exposure. This study evaluated the effect of dietary folate from natural folates plus folic acid fortification, separate from folic acid vitamin supplements, on age-6 year IQ in children with fetal-ASM exposure.MethodsData from the Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) study were retrospectively analyzed for this investigation. Assessment of nutrient intake was conducted using the Block Food Frequency Questionnaire-98. The primary outcome of the present study was to assess association of maternal prepregnancy nutrient levels to child age-6 IQ.ResultsFolate from food alone without supplement was not associated with improvement of age-6 IQ in children with fetal ASM exposure (95% CI: -11.7-2.3, p = 0.187). Periconceptual folate supplement use was associated with a 10.1-point higher age-6 IQ (95% CI: 5.2-15.0, p < .001). Total combined folate from food plus supplement also showed that higher intake of folate was associated with higher age-6 IQ (Coefficient: 4.5, 95% CI: 2.0-6.9, p < .001). Six other nutrients from food and supplements were analyzed (Vitamin C, Vitamin D, Vitamin E, Omega 3, Gamma Tocopherol, and Vitamin B12) and had no significant association with age 6-IQ.SignificanceDietary content of folate, even in a country where food is fortified with folic acid, is not sufficient to provide improved cognitive outcomes for children of women taking ASMs during pregnancy. Folate supplementation is needed for significant improvement in cognitive outcomes, specifically age-6 IQ.

Project description:The present study demonstrated that defatted soybean flour (DSF) can sorb polyphenols from blueberry and cranberry juices while separating them from sugars. Depending on DSF concentration and juice dilution, the concentration of blueberry anthocyanins and total polyphenols sorbed to DSF ranged from 2 - 22 mg/g and 10 - 95 mg/g, respectively while the concentration of anthocyanins and proanthocyanidins in cranberry polyphenol-enriched DSF ranged from 2.5 - 17 mg/g and 21 - 101 mg/g, respectively. Blueberry polyphenols present in one serving of fresh blueberries (73g) were delivered in just 1.4 g of blueberry polyphenol-enriched DSF. Similarly, one gram of cranberry polyphenol-enriched DSF delivered the amount of proanthocyanidins available in three 240 ml servings of cranberry juice cocktail. The concentration of blueberry anthocyanins and total polyphenols eluted from DSF remained constant after 22 weeks of incubation at 37°C, demonstrating the high stability of the polyphenol-DSF matrix. LC-MS analysis of eluates confirmed DSF retained major cranberry and blueberry polyphenols remained intact. Blueberry polyphenol-enriched DSF exhibited significant hypoglycemic activities in C57bl/6J mice, and cranberry polyphenol-enriched DSF showed anti-microbial and anti-UTI activities in vitro, confirming its efficacy. The described sorption process provides a means to create protein-rich food ingredients containing concentrated plant bioactives without excess sugars, fats and water that can be incorporated in a variety of scientifically validated functional foods and dietary supplements.

Project description:BACKGROUND:In Mexico, the fortification of corn and wheat flours with iron, zinc, and folic acid and the restoration of B-vitamins is a mandatory program. However, the monitoring and evaluation (M&E) of this fortification process is not well understood. Thus, the purpose of the study was to understand the M&E of the food fortification program in Mexico, with an emphasis on technology research and development. METHODS:Open-ended exploratory interviews were conducted with food technology representatives (n = 9), food science academic faculty (n = 1), president of a private tortilla-making federation (n = 1), and representatives of the federal monitoring agency (n = 2). Interviews were transcribed and themes were identified using the content analysis methodology. Inter-rater reliability was assessed by calculating an intraclass correlation coefficient (ICC) between the raters (n = 3). RESULTS:A total of 49 codes were identified that resulted in three overarching themes, manufacturing/processing, monitoring logistics, and nutrition. Overall, there is a need for more robust internal and external M&E with Mexico's fortification program to improve the manufacturing/processing of fortifying the tortillas, the monitoring of this fortification program, and the impact the fortified tortillas have on the nutritional status of the Mexican population. The overall ICC was 0.87. CONCLUSIONS:The present study can be used to gain insight into Mexico's fortification program and to inform food fortification policymakers of best practices.

Project description:This paper comprehensively investigates various aspects of dietary behaviors relating to the usage of wheat flour and sociocultural preferences embedded within rural communities and aims to bridge health gaps resulting from zinc deficiency by introducing zinc bio-fortified and fortified flour in Pakistan. A household and a market study was conducted in Ghotki and Tando Muhammad Khan districts in Sindh, Pakistan. Various stakeholders involved in the wheat-flour industry including farmers, seed suppliers, owners of atta-chakkis and flour mills, grocers and flour merchants, bakers and hoteliers, consumers, and agronomists were interviewed to gauge their knowledge of bio-fortified and fortified wheat-flour. Wheat-flour is a staple food item in Pakistan, however, agricultural output in Pakistan varies across all provinces. Factors that hinder agricultural productivity include a shortfall of essential resources such as irrigation water, superior quality seeds and fertilizers, and machinery. Farmers use primitive methods of farming as they do not have access to modern technologies, information, or training. Wheat flour market vendors and consumers lack awareness of bio-fortified and fortified wheat flour products and believe the only way to create a customer-base is by ensuring that fortified wheat products are available to all and competitively priced compared to traditional options. Additionally, participants misconstrue the process of fermentation and perceive it as unhealthy. The lack of financial resources and awareness restricts adequate promotion of nutrient-rich food products amongst stakeholders involved in the wheat flour industry. Mass awareness campaigns, education and government incentives could bridge the gaps present and encourage wider adoption of bio-fortified and fortified wheat flour. Policy makers and communities can draw on the recommendations made in this paper to introduce and promote zinc bio-fortified and zinc-fortified flour in settings where zinc deficiency is prevalent.

Project description:Iron (Fe) deficiency is one of the most common nutritional disorders, and is mainly due to insufficient intake of bioavailable Fe. Chickpea (Cicer arietinum L.) was examined as a potential vehicle for Fe fortification. Fortificants (FeSO4·7H2O (ferrous sulfate hepta-hydrate), FeSO4·H2O (ferrous sulfate mono-hydrate) and NaFeEDTA (ethylenediaminetetraacetic acid iron (iii) sodium salt)) were applied by a spraying and drying method. At 2000 µg g-1 iron fortificant, the fortified split desi seeds (dal), desi flour and kabuli flour supplied 18-19 mg, 16-20 mg and 11-19 mg Fe per 100 g, respectively. The overall consumer acceptability using a nine-point hedonic scale for sensory evaluation demonstrated that NaFeEDTA-fortified cooked chickpea (soup and chapatti) scored the highest among the three fortificants. Lightness (L*), redness (a*) and yellowness (b*) of Fe-fortified products changed over time. However, no organoleptic changes occurred. Fe bioavailability was increased by 5.8-10.5, 15.3-25.0 and 4.8-9.0 ng ferritin mg-1 protein for cooked split desi seeds (soup), desi chapatti and kabuli chapatti, respectively, when prepared using Fe-fortified chickpea. Desi chapatti showed significantly higher Fe bioavailability than the other two. The increase in Fe concentration and bioavailability in fortified chickpea products demonstrated that these products could provide a significant proportion of the recommended daily Fe requirement.

Project description:Calcium intake is low in many countries, especially in low-income countries. Our objective was to perform a simulation exercise on the impact, effectiveness, and safety of a flour fortification strategy using the Intake Modelling, Assessment, and Planning Program. Modeling of calcium fortification scenarios was performed with available dietary intake databases from Argentina, Bangladesh, Italy, the Lao People's Democratic Republic (Lao PDR), Uganda, Zambia, and the United States. This theoretical exercise showed that simulating a fortification with 156 mg of calcium per 100 g of flour would decrease the prevalence of low calcium intake, and less than 2% of the individuals would exceed the recommended calcium upper limit (UL) in Argentina, Italy, Uganda, and Zambia. Bangladesh and the Lao PDR showed little impact, as flour intake is uncommon. By contrast, in the United States, this strategy would lead to some population groups exceeding the UL. This exercise should be replicated and adapted to each country, taking into account the updated prevalence of calcium inadequacy, flour consumption, and technical compatibility between calcium and the flour-type candidate for fortification. A fortification plan should consider the impact on all age groups to avoid the risk of exceeding the upper levels of calcium intake.

Project description:Flaxseed is a popular functional food ingredient that is widely used in various snack foods. In this study, we developed a Chinese steamed bread (CSB) enriched with flaxseed flour. We evaluated the relative nutritional quality of flours made from distinct parts of flaxseeds, and we investigated the effects of adding various amounts of flaxseed flour on the edible acceptance and nutritional quality of CSB. The results showed that with increased flaxseed flour, the crust and core of CSB became darker, hardness and chewiness increased, cohesiveness and springiness changed slightly, the essential amino acid and resistant starch (RS) content increased significantly. Chemical analysis indicated that the major volatile compounds of CSB were alcohols and nitrogen-containing compounds. The RS ranged from 34.89 ± 0.80 to 54.64 ± 0.23%. The antioxidant capacity increased nearly three-fold. In summary, our study showed that the addition of 10% flaxseed flour yielded CSB with increased nutritional value and popular edible acceptance.
