Modeling the survival kinetics of Salmonella in tree nuts for use in risk assessment.
Salmonella has been shown to survive in tree nuts over long periods of time. This survival capacity and its variability are key elements for risk assessment of Salmonella in tree nuts. The aim of this study was to develop a mathematical model to predict survival of Salmonella in tree nuts at ambient storage temperatures that […]
Prevalence, Level, and Types of Salmonella Isolated from North American In-Shell Pecans over Four Harvest Years.
In-shell pecan samples (500 g) were collected over four harvest seasons (2010 to 2014) from seven pecan shelling facilities located in five U.S. states. Four varieties of pecans were analyzed: Mexican Improved, Native Seedlings, Southern Improved, and Western Improved. Pecan samples (100 g) were sent to a third party laboratory for initial Salmonella screening. When […]
Bioavailability assessment of essential and toxic metals in edible nuts and seeds.
Bioavailability of essential and toxic metals in edible nuts and seeds has been assessed by using an in vitro dialyzability approach. The samples studied included walnuts, Brazil nuts, Macadamia nuts, pecans, hazelnuts, chestnuts, cashews, peanuts, pistachios and seeds (almond, pine, pumpkin and sunflower). Metals were measured by inductively coupled plasma-mass spectrometry in dialyzates and also […]
Development and inter-laboratory transfer of a decaplex polymerase chain reaction assay combined with capillary electrophoresis for the simultaneous detection of ten food allergens.
Food allergies cause health risks to susceptible consumers and regulations on labeling of food allergen contents have been implemented in many countries and regions. To achieve timely and accurate food allergen labeling, the development of fast and effective allergen detection methods is very important. Herein, a decaplex polymerase chain reaction (PCR) assay combined with capillary […]
Cor a 14 is the superior serological marker for hazelnut allergy in children, independent of concomitant peanut allergy.
BACKGROUND: Hazelnut is the most frequent cause of tree-nut allergy, but up to half of all children with hazelnut allergy additionally suffers from peanut allergy. Our aim was to identify diagnostic values of the most promising serological markers (Cor a 9 and Cor a 14) and to address the influence of concomitant peanut allergy and […]
Is a Cardio-Protective Diet Sustainable? A Review of the Synergies and Tensions Between Foods That Promote the Health of the Heart and the Planet.
There are many synergies between a diet that is healthy for the heart and one that is healthy for the planet, but there may also be tensions. We examined the Barilla Center for Food and Nutrition's double pyramid to describe the carbon, water, and ecological footprints of the components of a cardio-protective diet. Overall, fruits, […]
A systematic review and meta-analysis of nut consumption and incident risk of CVD and all-cause mortality
Dietary patterns containing nuts are associated with a lower risk of CVD mortality, and increased nut consumption has been shown to have beneficial effects on CVD risk factors including serum lipid levels. Recent studies have reported on the relationship between nut intake and CVD outcomes and mortality. Our objective was to systematically review the literature […]
Effects of tree nuts on blood lipids, apolipoproteins, and blood pressure: systematic review, meta-analysis, and dose-response of 61 controlled intervention trials
BACKGROUND: The effects of nuts on major cardiovascular disease (CVD) risk factors, including dose-responses and potential heterogeneity by nut type or phytosterol content, are not well established. OBJECTIVES: We examined the effects of tree nuts (walnuts, pistachios, macadamia nuts, pecans, cashews, almonds, hazelnuts, and Brazil nuts) on blood lipids [total cholesterol, low-density lipoprotein (LDL) cholesterol, […]
Mediterranean Diet and Invasive Breast Cancer Risk Among Women at High Cardiovascular Risk in the PREDIMED Trial: A Randomized Clinical Trial.
IMPORTANCE: Breast cancer is the leading cause of female cancer burden, and its incidence has increased by more than 20% worldwide since 2008. Some observational studies have suggested that the Mediterranean diet may reduce the risk of breast cancer. OBJECTIVE: To evaluate the effect of 2 interventions with Mediterranean diet vs the advice to follow […]
Phenolic content and anti-hyperglycemic activity of pecan cultivars from Egypt
CONTEXT: Pecans are commonly used nuts with important health benefits such as anti-hyperglycemic and anti-hyperlipidemic effects. OBJECTIVE: A comparative investigation of the antihyperglycemic and total phenolic content of the leaves and shells of four pecan cultivars growing in Egypt was carried out. The selected cultivars (cv.) were Carya illinoinensis Wangneh. K. Koch. cv. Wichita, cv. […]
