Dose Response Effects of Pecan Consumption on Blood Lipid Profiles in Adults with Excess Body Weight and/or Dyslipidemia: A Randomized Controlled Trial

Background: Consuming ≥20% of daily energy from pecans improves blood lipids and reduces dyslipidemia but exceeds dietary recommendations. The benefits of lower doses remain unclear. Objective: Examine the effects of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on fasting and postprandial blood lipids in adults with excess body weight […]

Valorization and Environmental Impacts of Pecan Waste: A Critical Review

Pecan (Carya illinoinensis) cultivation generates a substantial number of byproducts, particularly nutshells, which are often discarded despite being rich in bioactive and structural compounds. These agro-industrial residues, comprising nearly 50% of the total nut mass, contain high levels of phenolics, flavonoids, dietary fiber, and lignocellulosic matter, making them suitable for circular economy applications. This review […]

Effect of different drying methods at temperatures on nutrition quality of pecan

There are fewer reports on the nutritional quality of pecans subjected to drying temperatures. In this study, we explored the effects of four drying temperatures (freeze-drying (FD), low-temperature drying (LD), medium-temperature drying (MD), and high-temperature drying (HD)) on the nutritional quality of pecans (Carya illinoinensis). The results demonstrated that MD significantly increased (p < 0.05) the content […]

Nutrient Displacement Associated with Replacing Intake of Usual Snacks with Pecans: An Exploratory Analysis of a Randomized Controlled Trial

Background: The effect of instructions to replace usual snacks with nuts on nutrient displacement is unknown. Objectives: This analysis aimed to investigate nutrient displacement and changes in food pattern component intake that occur with instructions to consume 57 g/d of pecans in place of usual snacks in adults at increased risk of cardiometabolic diseases after […]

Mitigating tropical cyclone susceptibility in pecan (Carya illinoinensis) orchards

The production of tree nuts such as almonds, walnuts, pistachios, and pecans is a globally important agricultural industry. Climate risk posed to tree nut orchards was recently brought to light by a series of severe tropical cyclone impacts to the primary pecan-producing areas of Georgia, USA which caused $1.2 billion USD in losses. Understanding how […]

Pecan Consumption Improves Cardiometabolic Risk Factors in Overweight and Obese Adults

Objectives: Tree nut intake benefits cardiometabolic health, but polyphenol-rich pecans have been less studied. The aim of this dissertation was to evaluate the cardiometabolic effects of consuming pecans in place of usual snacks compared to usual intake in adults at risk for cardiometabolic diseases. Methods: This was a 12-week parallel randomized controlled trial in which […]

Study on techno-functional properties of pecan flour with different lipid content

Pecan flour, obtained from the solid residue left after walnut oil extraction, is rich in proteins, dietary fiber, and phenolic compounds with antioxidant properties. This study evaluates the techno-functional properties of pecan flour with varying lipid contents. Key parameters include color (L*, a*, and b* values), bulk density, oil absorption capacity (OAC), water absorption capacity […]

Pecan Intake Improves Lipoprotein Particle Concentrations Compared with Usual Intake in Adults at Increased Risk of Cardiometabolic Diseases: A Randomized Controlled Trial

Background: Pecan consumption consistently improves lipoproteins, but less research has investigated the effect of pecans on lipoprotein subfractions. Objectives: The aim was to investigate the effect of substitution of usual snack foods with 57 g/d of pecans on lipoprotein particle subfractions and apolipoproteins compared with continuing usual intake after 12 wk. Exploratory analyses evaluated effects […]

Consuming Pecans as a Snack Improves Lipids/Lipoproteins and Diet Quality Compared to Usual Diet in Adults at Increased Risk for Cardiometabolic Diseases: A Randomized Controlled Trial

Background: The vascular and cardiometabolic effects of pecans are relatively under-studied. Objectives: The aim was to examine how substitution of usual snack foods with 57 g/day of pecans affects vascular health, risk factors for cardiometabolic diseases and diet quality, compared to continuing usual intake in individuals at risk for cardiometabolic diseases. Methods: A 12-week single-blinded, […]
