“…The dos sponse relationships between the percentage of energy from almonds in the Step 1 and changes in TC, LDL-C, Apo-B, and in HDL-C are shown in Figure 26. Rajaram et al [84], in a crossover, controlled RCT, randomly assigned 25 he adults (14 women and 11 men, mean age 41 years, mean body weight 71 kg) to o three heart-healthy 2000 kcal diets for 4 weeks each: (1) nut-free control diet (<30% e from fat), (2) low almond diet (10% of energy, 34 g almonds/day, 35% total energy fat), or (3) high almond diet (20% of energy, 68 g almonds/day, 39% total energy from consumed as snacks or incorporated into foods such as pizza or salads. Serum E-se (a cell adhesion molecule expressed by endothelial cells) decreased as the % energy almonds increased (p < 0.0001).…”

This comprehensive narrative review of 64 randomized controlled trials (RCTs) and 14 systematic reviews and/or meta-analyses provides an in-depth analysis of the effect of almonds on weight measures, metabolic health biomarkers and outcomes, and the colonic microbiota, with extensive use of figures and tables. Almonds are a higher energy-dense (ED) food that acts like a lower ED food when consumed. Recent systematic reviews and meta-analyses of nut RCTs showed that almonds were the only nut that had a small but significant decrease in both mean body mass and fat mass, compared to control diets. The biological mechanisms for almond weight control include enhanced displacement of other foods, decreased macronutrient bioavailability for a lower net metabolizable energy (ME), upregulation of acute signals for reduced hunger, and elevated satiety and increased resting energy expenditure. The intake of 42.5 g/day of almonds significantly lowered low-density lipoprotein cholesterol (LDL-C), 10-year Framingham estimated coronary heart disease (CHD) risk and associated cardiovascular disease (CVD) medical expenditures. Diastolic blood pressure (BP) was modestly but significantly lowered when almonds were consumed at >42.5 g/day or for >6 weeks. Recent RCTs suggest possible emerging health benefits for almonds such as enhanced cognitive performance, improved heart rate variability under mental stress, and reduced rate of facial skin aging from exposure to ultraviolet (UV) B radiation. Eight RCTs show that almonds can support colonic microbiota health by promoting microflora richness and diversity, increasing the ratio of symbiotic to pathogenic microflora, and concentrations of health-promoting colonic bioactives. Almonds are a premier healthy snack for precision nutrition diet plans.

Background Avocados are a rich dietary source of monounsaturated fatty acids, carotenoids, and phenolic compounds. Clinical studies have demonstrated that oral consumption of carotenoids improved skin aging. However, no studies have investigated whether oral intake of avocado will reduce skin aging. Objectives We therefore performed this pilot study to assess whether oral consumption of one avocado daily for 8 weeks can reduce skin aging in healthy overweight women assessing skin physical characteristics and resistance to UVB radiation. Methods Thirty‐nine female participants (age 27–73 years) with Fitzpatrick skin type II‐IV were randomly assigned to consume either one avocado daily or continue habitual diet for 8 weeks. Facial skin elasticity, firmness, pigmentation, sebum, and hydration were determined using a cutometer on the forehead and under eye. Minimal erythema dose (MED) was determined by standardized protocol at inner arm. Results Elasticity and firmness were increased at forehead comparing 8 weeks to baseline in the avocado group. Comparing avocado to control, change in firmness marker from baseline to week 8 indicated a significant increase in forehead skin firmness in the avocado group. We did not observe any change in hydration, pigmentation, sebum, and UVB resistance between the avocado and control group, although changes in melanin and erythema were observed in both groups over time. Conclusions Our findings suggest that daily oral avocado consumption may lead to enhanced elasticity and firmness of the facial skin in healthy women. Further studies of other skin locations are required to establish the connection between avocado consumption and skin aging.

“…In addition to UV inducing local and systemic inflammatory processes, PI-MED testing may serve as an indirect assay of systemic inflammation levels. For example, a number of studies have demonstrated that consuming certain nutritional supplements with antioxidant properties, thought to ameliorate systemic inflammation, also reduces erythema response to UV [34][35][36][37] and decreases UV-induced pro-inflammatory cytokines in the skin and blood 32 , suggesting that the body's general inflammatory environment can be indirectly assessed via UV-induced erythema response. Thus, PI-MED offers a relatively inexpensive procedure for assessment (especially repeated assessment) of peripheral inflammatory tone compared to blood-based and salivary protocols.…”

“…PI-MED offers real-world validity as the UVB inflammatory challenge is analogous to exposure from the sun, a common environmental stressor. In addition to offering a specific measure of inflammation in the skin, evidence suggests the cutaneous response is influenced by systemic factors [e.g., 32 , [34][35][36][37] ], thus suggesting PI-MED is also an indirect measure of general inflammatory tone.…”

Affective immunology of the skin is a growing area; however, established protocols for measuring individual differences in cutaneous inflammation are lacking. To address this, we present a preliminary validation of Precision Implementation of Minimal Erythema Dose (PI-MED) testing as a method for measuring cutaneous inflammation. PI-MED is a recently adapted protocol, optimized for reproducibility and individual differences research, that uses ultraviolet (UV) light to evoke cutaneous erythema, or inflammatory skin reddening. PI-MED’s novel UV dosage schedule produces standardized erythema responses across different skin pigmentation types and shows strong internal consistency within person and good test–retest reliability across 8–10 weeks. In line with predictions, increased PI-MED erythema was associated with heightened anhedonia, across several measures, beyond influences of non-affective covariates. While future work should further refine the dosage schedule for the lightest and darkest skin types, overall, evidence supports PI-MED as a protocol for inducing and measuring individual differences in cutaneous inflammation. Further, PI-MED-induced erythema can expand psychoneuroimmunology research by offering a complementary assessment for general inflammatory tone. This work adds to a growing body of evidence demonstrating a distinct relationship between inflammation and anhedonia.
