The potential role of plant-based foods in the promotion of skin health is an emerging area of nutrition research. Plant-based foods are rich in bioactive compounds, including vitamin C, vitamin E, beta carotene, polyphenols, and phenolic acids, which can contribute to oxidant defense, lower inflammation, and promote structural support of the skin. Epidemiological studies have associated higher intakes of select fruits and vegetables with positive skin health. Beneficial effects of certain fruits, vegetables, nuts, legumes, and polyphenolic-rich beverages on the skin have been reported, with each of these providing a unique phytochemical composition. Although most studies use extracts, this review will focus on data from whole foods and minimally processed products. Collectively, the evidence to date suggests a promising future for plant-based dietary interventions that promote skin barrier health and function. However, additional research is required to address issues such as the optimal quality and duration of intake as well as potential mechanisms. Studies in the above areas will help formulate specific targeted dietary recommendations.

Mangos are rich in β-carotene and other carotenoids, along with several phenolic acids that may provide oxidant defense and photoprotection to the skin. The objectives of this study are to investigate the effects of Ataulfo mango intake on the development of facial wrinkles and erythema. A randomized two-group parallel-arm study was conducted to assess 16 weeks of either 85 g or 250 g of mango intake in healthy postmenopausal women with Fitzpatrick skin type II or III. Facial photographs were captured at weeks 0, 8, and 16, and wrinkles at the lateral canthi and erythema at the cheeks were quantified. Skin carotenoid values were measured with reflection spectroscopy. Deep wrinkle severity decreased significantly in the 85 g group after 8 (p = 0.007) and 16 (p = 0.03) weeks compared to baseline measures. In contrast, those in the 250 g group showed an increase after 16 weeks in average wrinkle severity (p = 0.049), average wrinkle length (p = 0.007), fine wrinkle severity (p = 0.02), and emerging wrinkle severity (p = 0.02). Erythema in the cheeks increased with 85 g of mango intake (p = 0.04). The intake of 85 g of mangos reduced wrinkles in fair-skinned postmenopausal women, while an intake of 250 g showed the opposite effect. Further studies feeding 85 g of mangos are warranted.

Background: Children often consume up to 30% of calories from snacks that are usually low in nutrient value. Over time, poor dietary choices can contribute to an increased risk of obesity and related health problems. Purpose: Describe the development and utilization of the Self-paced Nutrition Activity on Choices for Knowledge (S.N.A.C.K.) nutrition education game to elicit and reinforce healthier snack choices by children aged 9 to 13 years. Methods: Children engaged in S.N.A.C.K. on a provided tablet for 15 to 25 minutes, at week 0 and 4. The game was self-paced, providing education about the Nutrition Facts Label, and consisted of three assessments to evaluate knowledge and application. Results: Data from 41 children, 59% normal weight, and 41% overweight/obese, were included in the analysis. Significant improvements in knowledge and utilization of the Nutrition Facts Label were observed immediately after education, with further advancement after a second session four weeks later. Discussion: In this study, children immediately improved, and sustained, their newly acquired nutrition knowledge with a single 15 to 25 minute session with S.N.A.C.K. Translation to Health Education Practice: Educators could incorporate this consistent and accurate education into their curriculum to reinforce a child’s nutrition knowledge over time.
