Economic costs of childhood stunting to the private sector in low- and middle-income countries.

Background: Stunting during childhood has long-term consequences on human capital, including decreased physical growth, and lower educational attainment, cognition, workforce productivity and wages. Previous research has quantified the costs of stunting to national economies however beyond a few single-country datasets there has been a limited number of which have used diverse datasets and have had a dedicated focus on the private sector, which employs nearly 90% of the workforce in many low- and middle-income countries (LMICs). We aimed to examine (i) the impact of childhood stunting on income loss of private sector workforce in LMICs; (ii) to quantify losses in sales to private firms in LMICs due to childhood stunting; and (iii) to estimate potential gains (benefit-cost ratios) if stunting levels are reduced in select high prevalence countries.

The effect of increasing intakes of plant protein on the protein quality of Canadian diets.

The 2015 Canadian Community Health Survey was used to investigate the protein content and protein quality of the diets consumed by adults (≥19 years) when plant protein is increased. Individuals ( = 6498) were allocated to quartiles of increasing proportions of protein from plant foods (Quartile 1: 0-24.9%; Quartile 2: 25%-49.

Faba bean meal, starch or protein fortification of durum wheat pasta differentially influence noodle composition, starch structure and in vitro digestibility.

Faba bean (Vicia faba L.) flour, starch concentrate (60% starch), protein concentrate (~60% protein) and protein isolate (~85% protein) were added to replace one-quarter of durum wheat semolina to enrich the nutritional quality and physiological functions of durum wheat (Triticum turgidum L.) pasta.

An examination of contributions of animal- and plant-based dietary patterns on the nutrient quality of diets of adult Canadians.

Dietary guidance and Canada's 2019 Food Guide encourage increased consumption of plant-based foods as a source of dietary protein. However, there is an absence of recent data on protein and nutrient intakes and quality of Canadian dietary patterns that might occur with increased plant protein intakes. This study compared food sources and nutrient intakes of Canadian adults within groups of increasing plant protein-containing diets.

Faba bean protein flours added to pasta reduce post-ingestion glycaemia, and increase satiety, protein content and quality.

The hypothesis that adding faba bean (FB) flour and its macronutrient concentrated flours to pasta reduces postprandial glycaemia and increases satiety was tested in 54 young adult males. Each consumed a serving of pasta made from durum wheat semolina (DWS) alone, or DWS flour with 25% of flours from whole FB (FBF), starch concentrate (FBS), protein concentrate (FBPC), or protein isolate (FBPI). Post-consumption measurements included postprandial blood glucose, insulin, C-peptide, GLP-1 and PYY, and subjective appetite, over 120 min.

Increased milk protein content and whey-to-casein ratio in milk served with breakfast cereal reduce postprandial glycemia in healthy adults: An examination of mechanisms of action.

This study describes the effects on glycemic response and the underlying mechanisms of action of increasing the protein concentration and decreasing the casein-to-whey ratio in milk when consumed with a high glycemic breakfast cereal. Twelve healthy men and women, aged 18 to 30 yr and with a body mass index of 20 to 24.9 kg/m, consumed (in random order) milk beverages (250 mL) containing either 3.

Acute decrease in plasma testosterone and appetite after either glucose or protein beverages in adolescent males.

Objective: Chronic testosterone blood concentrations associate with food intake (FI), but acute effects of testosterone on appetite and effect of protein and glucose consumption on testosterone response have had little examination.

Methods: In a randomized, crossover study, twenty-three adolescent (12-18 years old) males were given beverages containing either: (a) whey protein (1 g/kg body weight), (b) glucose (1 g/kg body weight) or (c) a calorie-free control (C). Plasma testosterone, luteinizing hormone (LH), GLP-1 (active), ghrelin (acylated), glucose, insulin and subjective appetite were measured prior (0) and at 20, 35 and 65 minutes after the consumption of the beverage.

Maternal fat-soluble vitamins, brain development, and regulation of feeding behavior: an overview of research.

Recent research shows a link between vitamin intake during pregnancy and offspring health. Inadequate intakes of water-soluble vitamins during pregnancy lead to obesity and characteristics of the metabolic syndrome, concurrent with altered developments in food intake regulatory pathways. Few studies, however, have reported on the effects of fat-soluble vitamins (A, D, E, and K) on the development of food intake regulatory pathways.

Hypersensitivity reaction to components of parenteral nutrition in pediatrics.

Very rare cases of hypersensitivity reactions to various constituents of parenteral nutrition (PN) have been reported in children. Adverse effects associated with PN administration have centered on metabolic, infectious, and mechanical complications. Here we describe three cases of hypersensitivity to components of PN.

Role of maternal vitamins in programming health and chronic disease.

Vitamin consumption prior to and during pregnancy has increased as a result of proactive recommendations by health professionals, wide availability of vitamin supplements, and liberal food-fortification policies. Folic acid, alone or in combination with other B vitamins, is the most recommended vitamin consumed during pregnancy because deficiency of this vitamin leads to birth defects in the infant. Folic acid and other B vitamins are also integral components of biochemical processes that are essential to the development of regulatory systems that control the ability of the offspring to adapt to the external environment.

High vitamin A intake during pregnancy modifies dopaminergic reward system and decreases preference for sucrose in Wistar rat offspring.

High multivitamin (HV) content in gestational diets has long-term metabolic effects in rat offspring. These changes are associated with in utero modifications of gene expression in hypothalamic food intake regulation. However, the role of fat-soluble vitamins in mediating these effects has not been explored.

A gestational diet high in fat-soluble vitamins alters expression of genes in brain pathways and reduces sucrose preference, but not food intake, in Wistar male rat offspring.

High intakes of multivitamins (HV) during pregnancy by Wistar rats increase food intake, body weight, and characteristics of the metabolic syndrome in male offspring. In this study, high-fat soluble vitamins were fed in combination during gestation to test the hypothesis that they partially account for the effects of the HV diet. Pregnant Wistar rats (14-16/group) were fed a recommended multivitamin diet (1-fold all vitamins) or high-fat soluble vitamin diet (HFS; 10-fold vitamins A, D, E, and K) during pregnancy.

Methyl vitamins contribute to obesogenic effects of a high multivitamin gestational diet and epigenetic alterations in hypothalamic feeding pathways in Wistar rat offspring.

Scope: High multivitamin (HV, tenfold AIN-93G) gestational diets fed to Wistar rats increase food intake, obesity, and characteristics of metabolic syndrome in the offspring. We hypothesized that methyl vitamins, and specifically folate, in the HV gestational diet contribute to the obesogenic phenotypes consistent with their epigenetic effects on hypothalamic food intake regulatory mechanisms.

Methods And Results: Male offspring of dams fed the AIN-93G diet with high methyl vitamins (HMethyl; tenfold folate, vitamins B12, and B6) (Study 1) and HV with recommended folate (HVRF) (Study 2) were compared with those from HV and recommended vitamin (RV) fed dams.

A high multivitamin diet fed to Wistar rat dams during pregnancy increases maternal weight gain later in life and alters homeostatic, hedonic and peripheral regulatory systems of energy balance.

High multivitamin (10-fold, HV) and high folic acid (Fol) diets fed to pregnant Wistar rats increase body weight and characteristics of the metabolic syndrome in their offspring. Our objective was to determine the effects of a HV maternal diet on dams and whether methyl vitamins contribute to these effects. Pregnant Wistar rats were fed AIN-93G diets containing either (1) recommended multivitamins (RV, control), (2) HV, (3) HV with recommended Fol (HVRF; 1-fold Fol), or (4) RV with high methyl group vitamins (HMethyl; 10-fold Fol, vitamin B12 and B6).

Increasing vitamin A in post-weaning diets reduces food intake and body weight and modifies gene expression in brains of male rats born to dams fed a high multivitamin diet.

High multivitamin gestational diets (HV, 10-fold AIN-93G levels) increase body weight (BW) and food intake (FI) in rat offspring weaned to a recommended multivitamin (RV), but not to a HV diet. We hypothesized that high vitamin A (HA) alone, similar to HV, in post-weaning diets would prevent these effects of the HV maternal diet consistent with gene expression in FI and reward pathways. Male offspring from dams fed HV diets were weaned to a high vitamin A (HA, 10-fold AIN-93G levels), HV or RV diet for 29 weeks.

High folate gestational and post-weaning diets alter hypothalamic feeding pathways by DNA methylation in Wistar rat offspring.

Excess vitamins, especially folate, are consumed during pregnancy but later-life effects on the offspring are unknown. High multivitamin (10-fold AIN-93G, HV) gestational diets increase characteristics of metabolic syndrome in Wistar rat offspring. We hypothesized that folate, the vitamin active in DNA methylation, accounts for these effects through epigenetic modification of food intake regulatory genes.

High Folic Acid Intake during Pregnancy Lowers Body Weight and Reduces Femoral Area and Strength in Female Rat Offspring.

Rats fed gestational diets high in multivitamin or folate produce offspring of altered phenotypes. We hypothesized that female rat offspring born to dams fed a gestational diet high in folic acid (HFol) have compromised bone health and that feeding the offspring the same HFol diet attenuates these effects. Pregnant rats were fed diets with either recommended folic acid (RFol) or 10-fold higher folic acid (HFol) amounts.
