“…30 GT metabolite, 2,7,8-trimethyl-2-(b-carboxuethyl)-6-hydroxychroman (g-CEHC), significantly inhibited cyclooxygenase-2 activity in lipopolysaccharide-activated macrophages and IL-1b-treated epithelial cells although g-CEHC was easily excreted. [30][31][32] Previous studies suggested that GT has a potential role in regulation of oxidative stress and inflammation at low dose (33 mg/kg body weight) in murine models. 30,31 Because of its strong nucleophilic properties, GT may be a more potent pro-apoptotic agent than AT in trapping ROS in colon cancer.…”

Gamma tocopherol has shown ameliorative effect on diabetic wound healing by regulation of inflammation, oxidative stress, and apoptosis demonstrated by nuclear factor kappa B, nuclear factor (erythroid derived 2)-like 2, and sirtuin-1. AbstractDelayed wound healing is one of the major diabetic complications. During wound healing process, the early inflammatory stage is important for better prognosis. One of antioxidant nutrient, gamma-tocopherol (GT) is considered to regulate inflammatory conditions. This study investigated the effect of GT supplementation on mechanism associated with inflammation, oxidative stress, and apoptosis during early cutaneous wound healing in diabetic mice. Diabetes was induced by alloxan injection in ICR mice. All mice were divided into three groups: non-diabetic control mice (CON), diabetic control mice (DMC), and diabetic mice supplemented with GT (GT). After two weeks of GT supplementation, excisional wounds were made by biopsy punches (4 mm). Diabetic mice showed increases in fasting blood glucose (FBG) level, hyper-inflammatory response, oxidative stress, and delayed wound closure rate compared to non-diabetic mice. However, GT supplementation reduced FBG level and accelerated wound closure rate by regulation of inflammatory response-related proteins such as nuclear factor kappa B, interleukin-1b, tumor necrosis factor-a, and c-reactive protein, and oxidative stress-related markers including nuclear factor (erythroid derived 2)-like 2, NAD(P)H dehydrogenase quinone1, heme oxygenase-1, manganese superoxide dismutase, catalase and glutathione peroxidase and apoptosis-related markers such as sirtuin-1, peroxisome proliferator-activated receptor gamma coactivator 1-, and p53 in diabetic mice. Taken together, GT would be a potential therapeutic to prevent diabetes-induced delayed wound healing by regulation of inflammatory response, apoptosis, and oxidative stress.

“…In the analysis, we considered three main groups and 14 subgroups of this category of food. We compared our results with the other studies published in the scientific literature on the Australian [ 66 ], Spanish [ 67 , 68 ], American [ 69 , 70 ], Korean [ 71 , 72 ], UK [ 61 ], and Dutch [ 73 ] populations. Such a comparison was made for energy and those nutrients whose supply in the Polish diet is 20% and more.…”

The aim of our study was to analyse vegetables, potatoes and their products as sources of energy and nutrients in the average diet in Poland. Representative data of the 2016 Household Budget Survey from 36,886 households were used. This is the largest study sample in Poland, so we generalized the conclusions to the whole population using the statement ‘average diet’. We analysed three main product groups: vegetables, vegetable products, and potatoes and potatoes products, dividing them into 14 subgroups (e.g., tomatoes, cabbage, carrots, other vegetables, and mushrooms). The percentages of energy, protein, carbohydrates, total fat, nine vitamins (thiamine, riboflavin, niacin, vitamin B6, folate, vitamin C, vitamin A, vitamin D, and vitamin E), seven minerals (calcium, phosphorus, sodium, potassium, iron, magnesium and zinc), and fibre from the analysed food subgroups are presented. Additionally, the influence of household characteristics on the supply of energy and nutrients from each subgroup of vegetables, potatoes, and their products was evaluated using cluster analysis. In the analysis, R programme and Kohonen neural networks were applied. Our study showed that vegetables, potatoes, and their products provide 7.3% of daily dietary energy supply. Vegetables contribute more than 20% of the supply of six nutrients: vitamin C (51.8%), potassium (32.5%), folate (31.0%), vitamin A (30.6%), vitamin B6 (27.8%), and magnesium (20.2%), as well as fibre (31.8%). Cluster analysis distinguished three clusters that differed in nutritional supply from vegetables, potatoes, and their products. Educational level, income measured by quintile groups, village size, socio-economic characteristics, urbanization degree, and land use were the most important factors determining differences between clusters.

“…Several epidemiological studies have shown that high intakes of carotenoids are associated with relatively low risks of chronic diseases including cardiovascular disease and certain types of cancers [ 6 - 8 ]. Korean adults obtain their vitamin A mainly from plant foods [ 10 ]. Therefore, higher intakes of carotenoids of Korean adults may play an essential role in potent antioxidant concentrations and modulating the pathogenesis of several chronic degenerative diseases [ 29 ].…”

“…Recently, Noh et al [10] reported that Korean adults obtained over 80% of vitamin A from plant foods. Although average vitamin A intakes of Koreans are over the Recommended Nutrient Intakes (RNI) given as µg RE [9], the vitamin A status of Koreans may not be acceptable.…”

“…The new equivalency factor by the IOM makes very little difference in assessing the adequacy of adult diets whose intake of animal products of vitamin A already exceeds their recommendations of vitamin A, while for adults who obtain most of their vitamin A from carotenoids of plant products, this new conversion factor, µg RAE, for provitamin A carotenoids makes an important difference in estimating their dietary vitamin A intakes. Recently, Noh et al [ 10 ] reported that Korean adults obtained over 80% of vitamin A from plant foods. Although average vitamin A intakes of Koreans are over the Recommended Nutrient Intakes (RNI) given as µg RE [ 9 ], the vitamin A status of Koreans may not be acceptable.…”

Dietary intakes and plasma concentrations of retinol and carotenoids were estimated in assessing the vitamin A status of Korean adults living in Seoul and the metropolitan area. Three consecutive 24-h food recalls were collected from 106 healthy subjects (33 males and 73 females) aged 20-59 years. Fasting blood samples of the subjects were obtained and plasma retinol and carotenoids were analyzed. The daily vitamin A intakes (mean ± SD) were 887.77 ± 401.35 µg retinol equivalents or 531.84 ± 226.42 µg retinol activity equivalents. There were no significant differences in vitamin A intakes among age groups. The retinol intake of subjects was 175.92 ± 129.87 µg/day. The retinol intake of the subjects in their 50's was significantly lower than those in their 20's and 30's (P < 0.05). Provitamin A carotenoid intakes were 3,828.37 ± 2,196.29 µg/day β-carotene, 472.57 ± 316.68 µg/day α-carotene, and 412.83 ± 306.46 µg/day β-cryptoxanthin. Approximately 17% of the subjects consumed vitamin A less than the Korean Estimated Average Requirements for vitamin A. The plasma retinol concentration was 1.22 ± 0.34 µmol/L. There was no significant difference in plasma retinol concentrations among age groups. However, the concentrations of β-carotene, lycopene, and lutein of subjects in their 50's were significantly higher than those of in their 20's. Only one subject had a plasma retinol concentration < 0.70 µmol/L indicating marginal vitamin A status. Plasma retinol concentration in 30% of the subjects was 0.70- < 1.05 µmol/L, which is interpreted as the concentration possibly responsive to greater intake of vitamin A. In conclusion, dietary intakes and status of vitamin A were generally adequate in Korean adults examined in this study.
