Pecan-enriched diet improves cholesterol profiles and enhances postprandial microvascular reactivity in older adults

Daily consumption of 68 g of pecans for 4 weeks resulted in greater reductions in fasting total cholesterol, low-density lipoprotein (LDL) cholesterol, non-high-density lipoprotein cholesterol, LDL particle number, and LDL medium compared to a nut-free diet. Postprandial triglyceride levels were suppressed with pecan consumption, and improvements in microvascular reactivity were observed. Fasting macro- and microvascular function remained unaffected. The findings suggest that pecan consumption may contribute to improved vascular health and reduced cardiovascular risk in older adults.

Daily pecan consumption, either as part of the diet or as a substitution for isocaloric foods, resulted in suppressed postprandial lipid peroxidation and elevated postprandial TAC. Fasting γ-tocopherol levels also increased in both pecan groups. These findings suggest that regular pecan consumption has a protective effect against oxidative stress following a high-fat meal in adults at risk for CVD.

Randomised Controlled Trial
The abstract outlines a randomized, parallel, controlled trial where 41 healthy adults aged between 50 and 75 were split into two groups. One group consumed 68 grams of pecans every day for four weeks, while the other group avoided all nuts. Blood samples were obtained from all participants before and after the intervention during fasting and at intervals of 30, 60, and 120 minutes after a meal high in saturated fats. Changes were observed in various parameters, including malondialdehyde - a marker for lipid peroxidation, total antioxidant capacity (TAC), glucose, and insulin levels.
The study revealed no significant variances in fasting or post-meal TAC, glucose, or insulin for the pecan consumers compared to the control group. However, there was a noticeable tendency towards a change in fasting lipid peroxidation driven by a minor reduction for the pecan group compared to the control group. Moreover, post-meal lipid peroxidation was suppressed in the pecan group, distinctly different from the control group's results. These outcomes propose that a diet enriched in pecans for one month can provide protection against post-meal oxidative stress in older adults.
Clinical Trials
Clinical trials are research studies that involve people and are conducted to evaluate the safety and efficacy of new treatments or interventions, such as drugs, medical devices, or behavioural therapies.
