The Association of Measures of the Micro- and Macro-Vasculature with Selenium and GPx Activity in a Young Bi-Ethnic Population: The African-PREDICT Study.

J Am Coll Nutr 2019 Mar 1:1-9. Epub 2019 Mar 1.

a Hypertension in Africa Research Team (HART) , North-West University , Potchefstroom , South Africa.

Objective: Selenium plays an important physiological role as component for antioxidant selenoproteins such as glutathione peroxidase (GPx). Since oxidative stress contributes to hypertension development, it is likely that selenium deficiency may contribute to the burden of cardiovascular disease. To better understand the involvement of selenium and GPx in the early development of cardiovascular disease, we investigated in young, healthy black and white African men and women whether measures of the micro- and macrovasculature are related to selenium and GPx activity.

Personalized Nutrition in Disrupting Cancer - Proceedings From the 2017 American College of Nutrition Annual Meeting.

J Am Coll Nutr 2019 Jan 4;38(1):1-14. Epub 2018 Dec 4.

o Weill Cornell Breast Center, Weill Cornell Medicine.

Cancer is a major public health problem and is the second leading cause of death in the United States and worldwide; nearly one in six deaths are attributable to cancer. Approximately 20% of all cancers diagnosed in the United States are attributable to unhealthy diet, excessive alcohol consumption, physical inactivity, and body fatness. Individual cancers are distinct disease states that are multifactorial in their causation, making them exceedingly cumbersome to study from a nutrition standpoint. Read More

Serum and Erythrocyte Biomarkers of Nutrient Status Correlate with Short-Term Α-Carotene, Β-Carotene, Folate, and Vegetable Intakes Estimated by Food Frequency Questionnaire in Military Recruits.

J Am Coll Nutr 2019 Feb 6;38(2):171-178. Epub 2018 Nov 6.

c Military Performance Division of the US Army Research Institute of Environmental Medicine , Natick , MA , USA.

Objective: Food frequency questionnaires (FFQs) estimate habitual dietary intake and require evaluation in populations of interest in order to determine accuracy. Thus, the purpose of this study was to determine agreement between circulating biomarkers and FFQ estimated dietary intake in a military population consuming all meals in a dining facility over 12 weeks.

Methods: 2014 Block FFQs were administered and fasted blood samples were drawn to assess nutritional biomarkers at the end of a 12-week training period in male (n = 141) and female (n = 125) Marine recruits undergoing initial military training. Read More

J Am Coll Nutr 2018 Nov 6:1-10. Epub 2018 Nov 6.

c Exercise Science and Nutrition Laboratory , Texas A&M University , College Station , Texas , USA.

Objective: This study examines the long-term effects of ingesting hydrolyzed beef protein versus carbohydrate on indirect markers of immunity during 10 weeks of endurance training in master-aged triathletes (n = 16, age 35-60 years).

Methods: Participants were randomly assigned to either a hydrolyzed beef protein (PRO, n = 8) or nonprotein isoenergetic carbohydrate (CHO, n = 8) condition, which consisted of ingesting 20 g of each supplement, mixed with water, once a day immediately post workout, or before breakfast on nontraining days. Salivary human neutrophil peptides (HNP1-3) were measured before and after performing an incremental endurance test to volitional exhaustion at both pre and post intervention. Read More

J Am Coll Nutr 2019 Feb 2;38(2):108-118. Epub 2018 Nov 2.

a Department of Otorhinolaryngology , Faculty of Medicine and Dentistry, Medical University of Warsaw , Poland.

Objectives: Chronic rhinosinusitis (CRS) is a disease that represents a challenging therapeutic problem. Vitamin D and its receptors (VDR) are involved in the regulation of the immune system and may play role in CRS. Objectives of this study were to assess the relationships between the total concentration of vitamin D (25VD3) in sera, vitamin D receptor (VDR) expression, 1α-hydroxylase expression, and clinical data, including age, gender, Sino-Nasal Outcome Test (SNOT-22), computerized tomography (CT) scan, allergy status, and vitamin D supplementation in CRS patients with (CRSwNP) and without nasal polyps (CRSsNP), and in a control group.

a Nutrition and Dietetics Department, Faculty of Allied Health Sciences , Chulalongkorn University , Bangkok , Thailand.

Resistant maltodextrin is a non-viscous dietary fiber that is fermentable in the colon by colonic bacteria. The objective of this review is to summarize the studies of resistant maltodextrin and its effect on metabolic profile, such as blood glucose, lipid profile, and body weight. Several studies support the idea that resistant maltodextrin may improve blood glucose, insulin sensitivity, lipid profile, and obesity. Read More

e Cellular and Molecular Research Center, Department of Pharmacology , Qazvin University of Medical Sciences , Qazvin , Iran.

Objective: The role of gut microbiota in the pathogenesis of several neurodegenerative disorders, including Alzheimer's disease (AD), via the gut-brain axis has recently been demonstrated; hence, modification of the intestinal microbiota composition by probiotic biotherapy could be a therapeutic target for these conditions. The aim of this study was to assess the effects of a probiotic formulation (Lactobacillus helveticus R0052 and Bifidobacterium longum R0175) on inflammatory and memory processes in lipopolysaccharide (LPS)-induced rats, one of the animal models used in peripherally induced neuroinflammation and neurodegeneration.

Methods: Rats were randomly divided into four groups (Control, LPS, Probiotic + LPS, and Probiotic). Read More

From Food for Survival to Food for Personalized Optimal Health: A Historical Perspective of How Food and Nutrition Gave Rise to Nutrigenomics.

J Am Coll Nutr 2019 Jan 3;38(1):84-95. Epub 2018 Oct 3.

a Department of Nutrition and Dietetics, Faculty of Health Sciences , Istanbul Yeni Yuzyil University , Istanbul , Turkey.

Human nutrition has progressed impressively from the hunter-gatherer mode to that of promising personalized nutrition for health optimization through advanced and sophisticated omics technologies. The contemporary major diseases, while having strong genetic components, do not conform to Mendelian genetics; hence, their expression/manifestation is not controlled by a single gene. Noncommunicable diseases such as obesity, cancer, type 2 diabetes mellitus, and cardiovascular disease are attributed to a series of chronic anomalies closely related to dietary, among other, environmental factors, and consistent deregulation of one or more groups of genes (polygenic).

Egg Intake Has No Adverse Association With Blood Lipids Or Glucose In Adolescent Girls.

J Am Coll Nutr 2019 Feb 3;38(2):119-124. Epub 2018 Oct 3.

a Preventive Medicine and Epidemiology, Department of Medicine , Boston University School of Medicine , Boston , Massachusetts , USA.

Objective: Longitudinal data on cardiometabolic effects of egg intake during adolescence are lacking. The current analyses aim to evaluate the impact of usual adolescent egg consumption on lipid levels, fasting glucose, and insulin resistance during late adolescence (age 17-20 years).

Methods: Data from 1392 girls, aged 9 to 10 at baseline and followed for 10 years, in the National Heart, Lung, and Blood Institute's National Growth and Health Study were used to examine the association between usual egg intake alone and in combination with other healthy lifestyle factors and late adolescent lipid levels, fasting glucose, and insulin resistance, measured as homeostasis model assessment of insulin resistance (HOMA-IR).
