Fruit position within the canopy affects kernel lipid composition of hazelnuts.

BACKGROUND: The aim of this research was to study the variability in kernel composition within the canopy of hazelnut trees. RESULTS: Kernel fresh and dry weight increased linearly with fruit height above the ground. Fat content decreased, while protein and ash content increased, from the bottom to the top layers of the canopy. The level […]

Dietary energy density and body weight changes after 3 years in the PREDIMED study.

The association of dietary energy density (ED) and overweight is not clear in the literature. Our aim was to study in 4259 of the PREDIMED trial whether an increase in dietary ED based on a higher adherence to a Mediterranean dietary pattern was associated with 3-year weight gain. A validated 137-item food-frequency questionnaire was administered. […]

An on-site, ultra-sensitive, quantitative sensing method for the determination of total aflatoxin in peanut and rice based on quantum dot nanobeads strip.

An on-site, ultra-sensitive, and quantitative sensing method was developed based on quantum dot nanobeads (QDNBs) and a test strip for the determination of total aflatoxins (AFTs) in rice and peanuts. The monoclonal antibody against AFT (mAbAFT) was homemade and labeled with QDNB. After the pre-coating of the AFT antigen on the test line (T line), […]

Association Between Dietary Factors and Mortality From Heart Disease, Stroke, and Type 2 Diabetes in the United States.

Importance: In the United States, national associations of individual dietary factors with specific cardiometabolic diseases are not well established. Objective: To estimate associations of intake of 10 specific dietary factors with mortality due to heart disease, stroke, and type 2 diabetes (cardiometabolic mortality) among US adults. Design, Setting, and Participants: A comparative risk assessment model […]

Protective Effect of Juglans regia L. Walnut Extract Against Oxidative DNA Damage.

Walnuts (Juglans regia L.) are relevant components of the Mediterranean diet providing important macronutrients, micronutrients and other bioactive constituents including unsaturated fatty acids, proteins, fiber, vitamins, minerals, phytosterols and polyphenols. Although the walnut beneficial effects in human health are widely recognized by a lot of epidemiologic studies very little is known regarding its effect on […]

Replacing American snacks with tree nuts increases consumption of key nutrients among US children and adults: results of an NHANES modeling study.

BACKGROUND: Replacing typical American snacks with tree nuts may be an effective way to improve diet quality and compliance with the 2015-2020 Dietary Guidelines for Americans (DGAs). OBJECTIVE: To assess and quantify the impact of replacing typical snacks with composite tree nuts or almonds on diet metrics, including empty calories (i.e., added sugars and solid […]

Dried Plum Ingestion Increases the Osteoblastogenic Capacity of Human Serum.

In cell culture studies, dried plum (Prunus domestica L.) polyphenols increased osteoblast alkaline phosphatase (ALP) activity, mineralized nodule formation, and the expression of the bone marker genes runt-related transcription factor 2 (RUNX2) and osterix. The purpose of this study was to determine whether human serum collected 1 and 2 h after dried plum ingestion influenced osteoblast […]

Comparing Thermal Process Validation Methods for Salmonella Inactivation on Almond Kernels.

Ongoing regulatory changes are increasing the need for reliable process validation methods for pathogen reduction processes involving low-moisture products; however, the reliability of various validation methods has not been evaluated. Therefore, the objective was to quantify accuracy and repeatability of four validation methods (two biologically based and two based on time-temperature models) for thermal pasteurization […]

Impact of processing conditions on the phytoprostanes profile of three types of nut kernels.

The goal of this work was the identification and quantification of phytoprostanes (PhytoPs) in three types of nuts: "Walnut", "Macadamia", and "Pecan". This study represents a first approach to the relationship between the quantitative and qualitative PhytoP profiles in the "Macadamia" and "Pecan" nuts subjected to fried salt or fried honey processing. The kernels were […]

Influence of controlled atmosphere on thermal inactivation of Escherichia coli ATCC 25922 in almond powder.

Heat controlled atmosphere (CA) treatments hold potential to pasteurize Salmonella enteritidis PT 30 in almonds. Nonpathogenic Escherichia coli ATCC 25922 was used as a surrogate species of pathogenic Salmonella for validation of thermal pasteurization to meet critical safety requirements. A controlled atmosphere/heating block system (CA-HBS) was used to rapidly determine thermal inactivation of E. coli […]
