“…Some studies suggested that stress factors indicate the elevated synthesis of carotenoids (Kim et al, 2012). Others show that polyphenol content increases during UV-stress to protect the plant tissues from damages (Ozzard et al, 2008). Similar results were obtained from measurements performed on fruits exposed to insect invasions (Felton et al, 1994;Hemingway & Laks, 1992).…”

“…malignant tumours, non-alcoholic fat liver, autoimmune diseases etc.) (Felton et al, 1994;Geösel et al, 2011;Ozzard et al, 2008) can be developed by the damages in DNA and the structural and functional proteins evoked by these reactive substances (Bagchi et al, 2000). Because of this, many studies investigated how efficient the different foods are (e.g.…”

“…UVB-treated white button mushrooms were chosen for the purpose of this study since nowadays they have become one of the novelty mushroom products with their increased vitamin D content, representing a natural source of this vitamin of high importance for the human nutrition (Ozzard et al, 2008). The other object is Sedum hybridum, a commonly applied species on green roofs, especially extensive green roofs for its exceptional tolerance for climatic conditions and high decorative value (Szőke et al, 2012).…”

Abstract.Investigation of stress level might be facilitated also in plant and horticultural sciences, but currently mainly morphological parameters are in use. Antioxidant activity routinely measured in food-oriented researches and several studies indirectly indicated that stress factors can influence this parameter. Our aim was to assess the potential direct indicator role of antioxidant activity in stress conditions. We measured the effects of UVB and soil-delivered stress on Agaricus bisporus and Sedum hybridum. Our results indicate that UVB slightly decreases, while the inadequate soil conditions increase antioxidant activity; hence these measurements are suitable for determining the level of stress in different living samples.

Bioavailability of vitamin D2 from UV-B-irradiated button mushrooms in healthy adults deficient in serum 25-hydroxyvitamin D: a randomized controlled trial

Background/Objectives: Mushrooms contain very little or any vitamin D 2 but are abundant in ergosterol, which can be converted into vitamin D 2 by ultraviolet (UV) irradiation. Our objective was to investigate the bioavailability of vitamin D 2 from vitamin D 2 -enhanced mushrooms by UV-B in humans, and comparing it with a vitamin D 2 supplement. Subjects/Methods: Fresh mushrooms were irradiated with an UV-B dose of 1.5 J/cm 2 , increasing vitamin D 2 content from o1 to 491 mg/100 g and made to an experimental soup. In this 5-week, single-blinded, randomized, placebo-controlled trial, 26 young subjects with serum 25-hydroxyvitamin D (25OHD) p50 nmol/l were randomly assigned into three groups ((a) mushroom, (b) supplement and (c) placebo). They received during winter (a) 28 000 IU (700 mg) vitamin D 2 via the experimental soup, or (b) 28 000 IU vitamin D 2 via a supplement or (c) placebo, respectively. Results: After 2 weeks, serum 25OHD was significantly higher in the mushroom than in the placebo group (P ¼ 0.001). The serum 25OHD concentrations in the mushroom and supplement groups rose significantly and similarly over the study period by 3.9 nmol/l (95% confidence interval (95% CI): 2.9, 4.8) and by 4.7 nmol/l per week (95% CI: 3.8, 5.7), respectively. Conclusions: We are the first to demonstrate in humans that the bioavailability of vitamin D 2 from vitamin D 2 -enhanced button mushrooms via UV-B irradiation was effective in improving vitamin D status and not different to a vitamin D 2 supplement. This trial was registered at http://germanctr.de as DRKS00000195.

Few Americans meet the recommendations of the Dietary Guidelines for Americans and many do not know how to apply food and nutrition information to develop a personal approach to preventing diet/lifestyle-related diseases. In a time of rapid technologic advancement and rewards for innovation, a critical opportunity in food and nutrition science exists for improving health and reducing disease risk. The National Center for Food Safety and Technology (NCFST) recently established the Health Promoting Foods research platform to support the availability of safe food by using emerging technologies for improving food quality and consumer choice. A workshop convened with leading regulators and nutrition, genetic, medical, toxicological, behavioral, and consumer scientists to: discuss challenges facing personalized nutrition and health, develop strategies to overcome challenges using innovations in food and information technology, and define and prioritize a short- and long-term research agenda for the research platform. The workshop included presentations and in-depth discussions on the state of the science in genomics, behavior, food, and information technology. Workshop participants identified gaps, intersections, and new opportunities for delivering individualized food-based solutions that would be more accessible, affordable, and convenient. The research agenda, which was developed within a framework of providing information and guidance to the food and associated industries, supporting the process for health-related claims, building consumer confidence in data and food-health information, and providing a pathway for implementation of the US Dietary Guidelines for Americans and other public policies, reflects the commitment of the community, government, food industry, health organizations, and academia to improving health.
