The purpose of this study was to investigate the effects of dietary habits and nutrient intakes on skin condition of female university students. The subjects were 95 female university students in Daegu. This study examined anthropometric measurements, dietary intake, food intake habits and skin condition (moisture, elasticity, sebum (U-zone, T-zone), pores, evenness and melanin pigmentation. The subjects in this study had an average age of 21.4, an average height and weight of 161.2 cm and 52.9 kg, respectively, and the average body mass index (BMI) was 20.3 $kg/m^2$. The means of skin elasticity, pores, evenness, and melanin pigmentation were within the normal range of women in their 20s and the skin moisture state was slightly lower than the normal range, which showed a dry tendency. The sebum in the U-zone and the T-zone was lower than the standard values, which showed less secretion in both areas. The subjects with high nut intake showed a better skin pore state (p < 0.05). Those with a high intake of instant foods showed a sig-nificantly low skin moisture and a significantly higher sebum rate (p < 0.05). The group with high skin elasticity and the group with less melanin pigmentation showed a significantly low animal protein intake (p < 0.05). The group with high skin elasticity also showed a significantly higher vitamin A and niacin intakes as well (p < 0.05). The group with high skin evenness showed a significantly lower animal lipid intake and a significantly higher vitamin E intake (p < 0.05). In addition, those with high skin elasticity and evenness as well as low melanin pigmentation showed a tendency of high intake of antioxidant vitamins, such as vitamin A, carotene, vitamin C or vitamin E. In summary, a moderate intake of plant-based products and also the antioxidant vitamins within such products seems to have a beneficial effect on maintaining a healthy and good skin condition.

The importance of beneficial microorganisms, particularly probiotics, that coexist in the human body, is being increasingly recognized. Probiotics are representative health functional foods that provide health benefits to humans through the production of various metabolites, including short-chain fatty acids. However, the health benefits are strain-specific, and the use of each probiotic strain should follow guidelines that assure its safety. Accurate identification of the strain should be managed through genetic and phenotypic analyses of the strain. Besides, the functionality of probiotics should be disclosed in vitro and in vivo so that they can be used as legal functional ingredients (i.e., individual standards). In this review, we deal with the guidelines, including the technical factors related to probiotic strains. The common health effects of probiotic strains include proliferation of beneficial bacteria, control of harmful bacteria, and facilitation of bowel activities. Probiotics with various functionalities (e.g., body fat and cholesterol reduction, vaginal health, and improvement of skin's immune system) have been investigated as "individual standards of raw materials for health functional foods" provided by MFDS. In the future, various biotechnologies including synthetic biology can be applied to produce customized probiotics to improve human health.

This study aimed to determine the anti-obesity effect of adding Wolfiporia extensa Ginns (W) to fermented pollack skin products in an obesity-induced animal model. The experimental groups were the normal diet group (C), high-fat diet group (HF), dried pollack skin (H1), fermented pollack skin (H2), and W of 0.1 (F2-WL), 0.3 (F2-WM), and 0.5 (F2), respectively. It was confirmed that adding W to fermented pollack skin reduced blood triglycerides, total cholesterol, and LDL levels, while increasing HDL levels. Wolfiporia extensa Ginns was effective in controlling weight and improving blood lipids in a dose-dependent manner. In histological analysis, findings of fatty liver induced by a high-fat diet were improved by the addition of H2 and W. Size and density of fat globules in the epididymis were decreased. In addition, the concentration of TNF-α was increased in the high-fat diet group, but decreased by the addition of fermented pollack skin and W. In conclusion, adding fermented dried pollack skin and Wolfiporia extensa Ginns was effective for weight control and blood lipid improvement. Thus, the use of by-products in functional foods is expected to have a high value in the future.

This study was conducted to investigate the prevalence of obesity and the concerns with omega 3 fatty acid intakes in 100 men do regular exercising. Most subjects were 23~66 years old whose average height and weight were 170.0$\pm$0.5cm and 68.2$\pm$0.8kg, respectively. Prevalence of obesity was 7%, 41% and 41% by criteria of Bioelectrical impedance analysis, Skin fold thickness and Body mass index, respectively. According to this survey, 75% of the subjects prefered vegetable oil to animal fat, 55% of them prefered seaweeds to shellfishes and 76% of them prefered natural foods to processed foods for good health. 61% of the interviewed subjects had the experience of eating perilla oil and 49% of them chose the Mackeral that had contained omega 3 fatty acids. The reason that seaweeds were good for health was rather high vitamin and mineral content than low fat.

Fermented milk including yogurt, which has a long tradition of thousands of years, was first established in Korea in 1919, and the current market size has grown to over 90 billion dollars. Fermented milk, which began in the early days of liquid yogurt, appeared on the market as spoonable and drinking yogurt. Fermented milk began with research on intestinal health functions and lactobacilli, and gradually developed into various disease prevention studies such as gastrointestinal health, immunity improvement, skin beauty, and prevention of dementia. As a simple meal, it has a nutrient function element, which serves as a meal replacement, and is expanding its range from general foods to special-purpose foods and dietary supplements. Fierce market competition is taking place, and as a result, the domestic fermented milk market is developing through the development of various products for differentiation.

This study was conducted to determine the incidence of microorganisms associated with dressed broiler with intact skin and without skin at different frozen storage periods such as 0, 10, 20, 30 days and to demonstrate the role of packaging and pretreatment chilling on the changes of carcass quality. The values of total viable count (TVC), total coliform count (TCC), total streptococcal count (TStC) and total staphylococcal count (TSC) were determined for meat samples of thigh and breast and swab samples of visceral surfaces of the broilers with intact skin and without skin. It was observed that the values of TVC, TCC, TStC and TSC in both cases of dressed broiler with intact skin and without skin exceeded the International Commission on Microbiological Specification for Foods. However, numbers of microorganisms were considerably decreased during the frozen storage. Packing and prechilled conditions were generally better effective in decrease of the loads of microorganisms than without packing and prechilled conditions, and lower bacterial numbers were also found in dressed broiler with intact skin than that without skin. The highest sensory panel score was obtained at 10 days of frozen storage. These results, thus, indicate that usages of appropriate periods and conditions of frozen storage and packaging systems can minimize the potential health hazards associated with contaminants gaining access to the dressed or processed broilers and improve the quality and shelf life of dressed broilers.

Spirulina is known to be more useful abroad than in Korea because it contains more protein than Chlorella, the same microalgae. In the past, sources of animal protein were diverse, but since it takes a long time to receive protein along with environmental pollution, we thought that spirulina could attract attention as a new protein source. In this study, application cases were analyzed in foods in the fields of acorn cake, tofu, dumpling skin, fish cake, white bread, pound cake, salad dressing, and yogurt and so on. As a result of centrally analyzing antioxidant and sensory evaluation, it was confirmed that the results were effective enough to develop products in tofu, dumpling skin, fish cake, and pound cake. It is thought that development of food in other fields will be possible if an additive amount that can match the consumer's preference is found by supplementing the mixing ratio. If it is used as a main raw material for existing food rather than as a raw material for health functional food, consumer preference can increase and quality can be further improved, and it can be suggested as a good alternative for an aging society.

In human beings, it is known that there is a correlation between the occurrence of acne and the ability to suppress sebum. Sebosuppression may be related to the inhibition of sebocyte proliferation, differentiation, and lipogenesis in sebaceous glands. To investigate the skin sebosuppressive activity of green tea extract, the in vivo effects of its flavonoid compounds on the androgen-dependent stimulation of pigmented macules in hamsters and performed in vitro experiments with human primary sebocytes were examined. Our results imply a dual activity of skin sebosuppression by green tea flavonoids; some catechins including epigallocatechin-3-gallate (EGCG) and gallocatechin-3-gallate (GCG) may reduce the differentiation of sebocytes by inhibiting PPAR-${\gamma}1$ mRNA expression, whereas some flavonol glycosides including kaempferol may inhibit lipogenesis in sebaceous glands by decreasing levels of the mature form of sterol-sensitive response elements binding protein-1c (SREBP-1c). Therefore, green tea is a potentially effective material for use in the development of health foods or cosmetics for skin sebosuppression.
