Summary: The study demonstrated that the positions and intensities of C-C and C=C stretching bands in Raman spectra depend on the length of the polyene chain and type of isomer. Experimental Raman spectra of beta-carotene powder matched well with DFT simulations for the all-trans form. Additionally, the presence of conjugated double bonds in a polyene structure leads to shifts in peak positions towards lower wavenumbers with increased intensities.

Summary: Plant-based foods are rich in bioactive compounds that are beneficial for skin health, such as vitamin C and polyphenols. Studies have shown a positive correlation between higher intake of certain fruits and vegetables and skin health. While plant-based dietary interventions show promise in promoting skin health, further research is needed to address issues such as intake quantity, quality, and mechanisms of action.

Summary: Despite evidence of the health benefits of consuming fruits and vegetables, many adults in the United States do not meet recommended intake levels. To address this, an accurate and convenient method for estimating dietary intake of fruits and vegetables is needed. Skin carotenoid levels measured by spectroscopy-based devices have shown promise as a proxy for fruit and vegetable intake, but there are factors that may affect these levels independently of actual intake.

Summary: This study evaluated the relationship between dietary carotenoid intake and S-Klotho plasma levels in older adults. The results showed a positive association between total carotenoid intake and S-Klotho levels, especially for alpha-carotene, beta-carotene, and lutein with zeaxanthin.

Summary: Lycopene, a pigment belonging to the group of carotenoids, is a powerful antioxidant that protects human health by inhibiting cancer cell proliferation, delaying cell cycle progression, and reducing cell transformation. Its beneficial properties are demonstrated through various molecular and cellular mechanisms in recent scientific studies.

Summary: Skin carotenoid status (SCS) measured by resonance Raman spectroscopy (RRS) and plasma carotenoids can serve as biomarkers for dietary carotenoid and fruit and vegetable (FV) intake in middle-aged and older Singaporeans, taking into account potential confounders like socio-demographics and nutritional factors.

Summary: Antioxidants play a vital role in defending against aging and chronic disease. The concentration of cutaneous carotenoids in the skin serves as a biomarker for antioxidant intake, and biofeedback can effectively improve cutaneous carotenoid levels. A study involving 44 adults found that providing biofeedback measurements, along with additional fruit juice intake, led to increased carotenoid levels over time. Therefore, biofeedback may offer a cost-effective method for monitoring and improving individual antioxidant status.

Summary: In this meta-analysis of 15 studies, a positive and statistically significant correlation was found between RRS-assessed skin carotenoids and plasma/serum carotenoids. The results indicated similar correlations in adults and children, with an overall correlation of 0.68 and 0.66, respectively.

Summary: The Veggie Meter (VM) has two modes, single-scan and averaging, which were tested on 92 healthy volunteers. Both modes showed high intra-class correlation coefficients (ICC); however, the averaging mode had lower coefficient of variance. Bland-Altman analysis revealed systematic errors between VM-1 and other three VMs. By using linear regression compensation, the error between VM-1 and the other three VMs in the averaging mode could be reduced, and the averaging mode showed higher accuracy than the single-scan mode. The reliability of the VMs was confirmed by low coefficient of variation and high ICC.

Summary: The current study investigates the effects of artificial UV-B radiation on the growth, proteins, pigments, and antioxidant enzymes in cyanobacterial strains. The results show increased production of phycocyanin and carotenoids under UV-B exposure in certain strains. Additionally, UV-B radiation affects the levels of non-enzymatic antioxidants and the expression of enzymatic enzymes. The study highlights the prominent antioxidant and radical scavenging properties of cyanobacteria in defense against UV-B induced cell damage.

Summary: The human gastrointestinal tract contains a diverse range of microbial species, which play a role in regulating gut barrier homeostasis, immune system stimulation, and neurological health benefits through the gut-brain axis. Dietary changes can significantly affect the gut microbial population, and positive changes can be made by changing dietary style. Dietary antioxidants, such as those found in food, have been found to have a positive impact on gut microbial populations, which can help alleviate gut microbial dysbiosis and contribute to the development of gut microbe-targeting therapeutics for various diseases. This review discusses the health benefits of major dietary antioxidant groups, and the interaction between gut microbiota and these antioxidants through pre-clinical and human dietary interventions.

Summary: Consumers are seeking greater functionality from food and beverage products, with polyphenols from roselle calyces and sweet basil leaves potentially providing therapeutic or preventive effects against chronic and infectious diseases. Analysis of roselle-basil drink samples showed that adding sweet basil leaves slightly decreased vitamin C and lycopene content but increased total carotenoid and antioxidant activities. Samples stored at higher temperature exhibited higher antioxidant activities, indicating that roselle-basil drink with added sweet basil leaves may serve as a health drink.
