Camp DASH Ancillary Studies

The Camp DASH study trial will compare the effect of two dietary patterns and two levels of sodium intake on blood pressure and blood lipids in adolescents in the upper third of distribution for blood pressure. The two dietary patterns are based on the Dietary Approaches to Stop Hypertension (DASH) trial in adults. Purdue University […]

Vitamin B12 and Perinatal Health: Elucidating Mechanisms and Biomarkers for Prevention of Birth Defects

Neural tube defects (NTDs) are one of the most common and severe birth defects in the United States and globally. Vitamin B12 deficiency and perturbations in one-carbon metabolism have been linked to common adverse pregnancy outcomes, including neural tube closure defects. Recent evidence from population studies have identified vitamin B12 deficiency as the leading nutritional […]

Impact of Fortification/Enrichment on Total Nutrient Intakes from Foods within Specific Groups by Socioeconomic Status

As part of its review every five years, the Dietary Guidelines Advisory Committee (DGAC) estimates the nutrient intake of the American population and identifies those nutrients of national concern. The Scientific Report of the 2015 DGAC identified “shortfall nutrients” and “overconsumed nutrients” and assessed which of those nutrients posed “substantial” public health concern. The aims […]

Novel Estimation of Energy Balance through the Calibration of Consumer Devices in Free-Living, Rural US Children

Children in rural areas are disproportionately affected by pediatric obesity. The American Heart Association has listed delivery of obesity treatment to rural families using mobile health (mHealth) as a major research priority. Improving the estimation of energy intake and balance is a priority for developing successful mHealth obesity treatment programs. The aims of this project […]

Dietary Patterns Associated with Cognition During Aging

In 2011, 15% of Canadians 65 and older were living with Alzheimer’s disease (AD), the most common form of dementia. Despite the fact that the cause of AD is not known, age and the presence of the epsilon 4 allele of apolipoprotein E (APOE4) are the most important risk factors.  Diet is central to health […]

Survival and Inactivation of Bacterial and Viral Pathogens in Model Low-Moisture Foods

Low-moisture food (LMF) products are often ingredients (e.g. nuts, dried fruits, cereal products, and chocolate) used in the manufacture of many food products. Because of this, they carry significant potential for the amplification of outbreaks and recalls over a wide variety of products. There has been worldwide recognition of the need to more seriously manage […]

Comparison and Analysis of Toxcast Data with In Vivo Data for Food-Relevant Compounds Using The Risk21 Approach

The IAFNS Food and Chemical Safety Committee invests in the training and education of future scientists and leaders in the fields of food and chemical safety and food toxicology by supporting a Summer Fellowship Program for doctoral students. This project focused on Comparison and Analysis of Toxcast Data with In Vivo Data for Food-Relevant Compounds […]

Demonstrating the Causal Beneficial Role of Microbes in Diet-Microbe-Host Interactions in Metabolic Disease

Over the past decade there has been an exponentially growing number of reports that describe changes in the microbial populations in response to dietary intervention. These changes in the microbiota are then associated with health outcomes with limited understanding of what changes in the microbial population really mean. Very few reports have demonstrated the specific […]

Listeria monocytogenes Thermal Resistance in Low-Moisture Foods: Role of Water Activity or Food Matrix

Low moisture foods (e.g., cocoa powder, dried milk powder, flour) have been increasingly involved in foodborne outbreaks. Foodborne pathogens such as Listeria monocytogenes can survive in low moisture foods and dry food processing environments for months, and even for years. However, there is a general lack of knowledge related to the behavior of L. monocytogenes […]

Exploring Nutritional and Metabolomic Pathways Linking Chronic Stress and Childhood Obesity

Chronic stress is a key risk factor for obesity and the accumulation of abdominal fat among children, which are harmful to long-term health. However, the mechanisms that underlie these relationships are poorly understood. This study will draw from a well-characterized cohort of children to provide some of the first data to explore two often-hypothesized, yet […]

Modeling the Impact of High-Oleic Soybean, Sunflower, and Canola Oils on Fatty Acid Intakes

Food production affords opportunities to select from a variety of commercially available fats/oils to achieve specific functional product characteristics. Widespread changes in the food supply, even if small for individuals, can shift population intakes and potentially modify cardiovascular risk. Modeling changes in advance of widespread commercial adoption can be used to predict the upper potential […]

Flavan-3-ols and Cardiovascular Disease Systematic Review and Meta-Analysis

Dietary flavonoids integrate a diverse range of polyphenolic compounds that occur naturally in plant foods. To date, the sub-class flavan-3-ols has received the most research attention, with the majority of nutrition studies focused on two dietary sources: tea and chocolate. It is not clear if the metabolic and cardiovascular health benefits may be attributed flavan-3-ols […]
