Sensory Analysis of a Processed Food Intended for Vitamin A Supplementation.

ABSTRACT: Provitamin A and pre-formed vitamin A compounds are essential micronutrients for humans. However, vitamin A deficiency (VAD) affects the health status of nearly 50% of populations in Southeast Asia and sub-Saharan Africa and is especially pronounced in preschool children and pregnant women. The objective of this research was to determine an acceptable flavor/ingredient combination to produce a palatable food product that incorporates sweet potatoes, peanut paste, and chickpeas. We sought to determine the acceptability of the three product formulations and to determine the influence of demographic data on ratings for the sensory attributes of each sample. To address VAD issues, three formulations of a product incorporating sweet potato puree (to increase ?-carotene content), pure peanut butter (to provide fat for ?-carotene absorption), and chickpeas (to provide a complete protein source), were developed: (1) an unflavored control, and two formulations with added natural seasonings: (2) curry-flavored, and (3) pumpkin spice-flavored. Sensory analysis of the three products showed that the curry-flavored product received the highest acceptability in terms of overall liking, flavor, texture, and appearance (p < 0.001). Since the demographic effect was not statistically significant (p > 0.05), it is highly likely that the curry-flavored product can be implemented in other countries or areas with high acceptability.

Project description:BackgroundIn recent decades there has been a global rise in consumption of ultra-processed foods (UPFs) to the detriment of population health and the environment. Large corporations that have focused heavily on low-cost manufacturing and extensive marketing of UPFs to maximise profits have driven this dietary transition. The same corporations claim to serve the interests of multiple 'stakeholders', and that they are contributing to sustainable development. This paper aimed to test these claims by examining the degree to which UPF corporations have become 'financialised', focusing on the extent to which they have prioritised the financial interests of their shareholders relative to other actors, as well as the role that various types of investors have played in influencing their governance. Findings were used to inform discussion on policy responses to improve the healthiness of population diets.MethodsWe adopted an exploratory research design using multiple methods. We conducted quantitative analysis of the financial data of U.S. listed food and agricultural corporations between 1962 and 2021, share ownership data of a selection of UPF corporations, and proxy voting data of a selection of investors between 2012 and 2022. We also conducted targeted narrative reviews using structured and branching searches of academic and grey literature.ResultsSince the 1980s, corporations that depend heavily on manufacturing and marketing UPFs to generate profits have been increasingly transferring money to their shareholders relative to their total revenue, and at a level considerably higher than other food and agricultural sectors. In recent years, large hedge fund managers have had a substantial influence on the governance of major UPF corporations in their pursuit of maximising short-term returns. In comparison, shareholders seeking to take steps to improve population diets have had limited influence, in part because large asset managers mostly oppose public health-related shareholder proposals.ConclusionsThe operationalisation of 'shareholder primacy' by major UPF corporations has driven inequity and undermines their claims that they are creating 'value' for diverse actors. Measures that protect population diets and food systems from the extractive forces of financialisation are likely needed as part of efforts to improve the healthiness of population diets.

Project description:IntroductionIt has been suggested that vitamin D is effective to prevent mortality. However, there is no consistent conclusion that the effects of vitamin D supplementation on all-cause mortality are associated with duration of treatment. We conducted a meta-analysis regarding this issue in an effort to provide a more robust answer.MethodsA comprehensive search in a number of databases, including MEDLINE, Embase and The Cochrane Central Register of Controlled Trials, was conducted for collecting randomized controlled trials (RCTs) on vitamin D supplementation preventing mortality. Two investigators independently screened the literature according to the inclusive and exclusive criteria and the relative data were extracted. Data analysis was performed by using Review Manager 5.0 software.ResultsData from forty-two RCT s were included. Vitamin D therapy significantly decreased all-cause mortality with a duration of follow-up longer than 3 years with a RR (95% CI) of 0.94 (0.90-0.98). No benefit was seen in a shorter follow-up periods with a RR (95% CI) of 1.04 (0.97-1.12). Results remain robust after sensitivity analysis. The following subgroups of long-term follow-up had significantly fewer deaths: female only, participants with a mean age younger than 80, daily dose of 800 IU or less, participants with vitamin D insufficiency (baseline 25-hydroxyvitamin D level less than 50 nmol/L) and cholecalciferol therapy. In addition, the combination of vitamin D and calcium significantly reduced mortality and vitamin D alone also had a trend to decrease mortality in a longer time follow up.ConclusionsThe data suggest that supplementation of vitamin D is effective in preventing overall mortality in a long-term treatment, whereas it is not significantly effective in a treatment duration shorter than 3 years. Future studies are needed to identify the efficacy of vitamin D on specific mortality, such as cancer and cardiovascular disease mortality in a long-term treatment duration.
