        In this study, Korean Hallabong produced in Jeju Island and coffee were grafted to prepare coffee containing Hallabong extract and the nutritional components were analyzed. As the amount of Hallabong extract increased, the water content and total polyphenol content increased. However, the crude flour, crude protein, and total flavonoid content decreased significantly. The selenium content per 100 g was 91.28 mg in the 1% Hallabong group, and the iron content was 6.84 mg in the 3% Hallabong group. As the content of Hallabong extract in coffee increased, the L-value (brightness) and b-value (yellowness) increased, but the a-value (redness) showed a tendency to decrease. In the case of DPPH(2,2-Diphenyl-1-picrylhydrazyl) radical scavenging activity, the group containing 9% of Hallabong extract showed the highest value at 47.20 μmol/g of TEAC. In particular, the ABTS(2,2’-Azino-bis(3-ethylbenzothiazoline- 6-sulfonate)) and DPPH radical scavenging activity were significantly increased from coffee powder containing 6% or more of Hallabong extract(p<0.05). The caffeine content decreased as the amount of Hallabong extract added to coffee increased. Therefore, when making powder coffee with Hallabong extract added, it is recommended to set the content of Hallabong extract to 6%.

        The purpose of this study was to develop a functional senior mixed soymilk for seniors and to provide functional senior-mixed soymilk to prevent disease outbreaks. The isoflavone content of senior soymilk was 0.15±0.01 mg/g. The β-glucan content of senior soymilk was 9.82±0.01 mg/g. The weight gain of mice were significantly higher in the high-fat diet group than in the other groups. The serum triglyceride content was high at 102.67±40.61 mg/dL in the high-fat diet group, but significantly lower at 83.00±42.43 mg/dL in the 20% senior soymilk group. Thus, the results of this study comprehensively suggest that food intake should be ingested for each life cycle with reference to the dietary reference intakes for Koreans. In particular, the elderly in their 50s and older are deficient in protein and weakened immune capacity, so it is imperative that they maintain their health through various foods such as soymilk, which is evenly nutritious.

        This paper defines the common features of synbiotics based on the definition of probiotics and prebiotics, and reviews the effectiveness of synbiotic food. The concept of synbiotics is defined as ‘a mixture of prebiotics and probiotics that have a beneficial effect on the host, as a dietary supplement that alters living organisms in the gastrointestinal tract and improves their survival.’ Synbiotic food contains ingredients with beneficial microbes that are expected to improve interactions between microbial and useful substances. Synbiotic foods may have anti-cancer and immune system-boosting effects. Improved digestion, healthier bowel movements, and overall increased intestinal health has been reported were reported after increasing the healthy microorganisms within the intestinal tract. In addition, depending on the type of food containing the symbiotic ingredients, more consistent weight control, improvement of cardiovascular health, and lower blood glucose levels may also be expected. Unlike previous studies, this review of synbiotics has shown that it is necessary for synergistic effects to take place among microorganisms and components to be further studied. Further research is needed on the safety and ingestion of microorganisms contained in synbiotics.

        Probiotics may be defined as microbial agents that can benefit humans and have been used primarily by mankind in fermented foods. A representative of probiotics is lactic acid bacteria (LAB), which has received attention recently due to its perceived health benefits. We reviewed research papers about Bifidobacerium and Lactobacillus, which are two of the most known of the LAB. Bifidobacerium alleviates diarrhea from various causes by improving intestinal microflora, and it has been reported that it reduces Helicobacter pylori bacteria known as the cause of gastric ulcer and stomach cancer. Bifidobacerium has also reported to be effective on immunization and allergy, reduce blood cholesterol, cancer, lactose intolerance. Lactobacillus alleviates diarrhea but has not fully demonstrated its effectiveness relative to other health issues. Several lactic acid bacteria and yeast are expected to act as probiotics, so, in the future, more research on the health benefits of lactic acid bacteria is needed.

        This study was conducted to investigate the characteristics of major prebiotics and the related studies, and to provide basic data for future research. Prebiotics are defined as ‘nondigestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon, and thus improve host health’. Well-known prebiotics are inulin, oligofructose, and galacto-oligosaccharide. Prebiotics assist in the health activity of lactic acid bacteria by acting as a substrate for lactic acid bacteria, with their unique physical and chemical properties. Bifidobacteria are known to be beneficial bacteria that prevent intestinal inflammation, maintain intestinal microflora balance, inhibit carcinogenesis, reduce cholesterol, and enhance immunity. However, Bifidobacteria, Lactobacillus, Bacillus, and Weissella are also found in animal-based fermented foods such as milk, cheese, yogurt, and salted fish. Prebiotics can act as a substrate for lactic acid bacteria, helping the activity of lactic acid bacteria and improving health. Therefore, the authors suggest that investigation into the category and effectiveness of prebiotics should be extended in the future through research.

        In this study, we analyzed the biochemical factors in lotus (Nelumbo nucifera) leaf, stem, and yeonjabang and their effects on serum factor levels in mice fed a high-fat (HF) diet. The loutus leaf showed 9.47±0.30% moisture content, 8.25±0.39% ash, 21.45±1.25% crude protein, and 2.21±0.13% crude fat content; the lotus stem showed 11.84±0.43% moisture, 10.21±0.64% ash, 17.55±0.92% crude protein, and 4.16±0.23% crude fat content; and the lotus yeonjabang showed 11.86±0.50% moisture, 6.81±0.51% ash, 18.71±1.02% crude protein, and 3.95±0.15% crude fat. Blood triglyceride levels were higher in the HF group (146.43±38.81 mg/dL), and lower in the HF+yeonjabang groups (98.00±17.18 mg/dL). In particular, blood triglyceride levels were significantly lower in the groups that had 10% dry yeonjabang powder added to the high-fat diet. The inclusion of excessive high-fat diet increased concentrations of serum insulin and leptin. Serum leptin concentrations were highest in the HF group mice (3.00±1.35 ng/dL), whereas they were significantly lower in the HF+yeonjabang groups by 1.34±0.52 ng/dL (p<0.05). Thus, addition of dry yeonjabang powder to the high-fat diet was more effective in regulating the levels of serum triglycerides and leptin in mice. Additional studies would help in the development of yeonjabang as a functional food.

        In this study, we determined the effect of the mulberry leaf powder on blood lipid metabolism and liver function improvement of mice fed a high fat diet. The mulberry leaf showed a moisture content of 10.74±0.56%, ash 9.67±0.56%, crude protein 25.24±1.02%, and crude fat 2.66±0.08%. In the group with high fat diet supplemented with mulberry leaf powder, serum low-density lipoprotein (LDL-cholesterol) and total cholesterol levels were significantly lower (p<0.05); also, serum phospholipid and aspartate amino transferase (AST) levels were significantly lower (p<0.05). Serum insulin and leptin levels were high in mice fed a high fat diet; however, addition of mulberry leaf powder 10% in the diet had no significant effect on blood insulin and leptin control. The results of the study suggested that various plant sterols in mulberry leaf improve lipid metabolism and liver function in ICR-mice.

        This study analyzed the antioxidant properties of Equisetum arvense and its effects on serum factor levels in mice fed a high-fat diet. The aim was to establish a new effective resource for biologically active materials. E. arvense stem and root extracts were obtained using deionized water at 95℃, and 70.5% ethanol at 85℃. These extracts were used to analyze the total phenolic compounds and antioxidant (ABTS, DDPH, and FRAP) activities. The effects of prepared ground samples were evaluated by feeding them to mice. E. arvense extracts showed strong antioxidant effects. The caffeic acid content was highest in the 70.5% ethanol extract of the vegetative stem, as determined by high-performance liquid chromatography. The blood concentrations of insulin and leptin were significantly lower in mice fed a high-fat diet supplemented with extracts of the root, reproductive stem, and vegetative stem of E. arvense than in mice fed only a high-fat diet. These results suggest that the polyphenolic compounds in E. arvense extracts exert various antioxidant effects. The stems and root of E. arvense can lower the blood levels of insulin and leptin, even after consumption of a high-fat diet.

        Taurine is an abundant amino acid in many animals, including humans. Relatively large amounts of taurine are found in leukocytes, heart, muscles, retinas, kidneys, bones, and liver. Taurine has antioxidant effects; it reacts with hydrogen peroxide to prevent oxidation of the cell membrane. Taurine enhances the effects of anticancer drugs, while also reducing side effects, and taurolidine, a taurine derivative, has been shown to exhibit anti-cancer effects without notable side effects in several types of cancer. Taurine aids in cholesterol metabolism by increasing the rate of synthesis of bile acids, and, thus, reduces triglyceride levels. In addition, taurine is involved in the growth and differentiation of nerve cells and is associated with some neurological disorders. Taurine aids in bone formation and prevents bone dissolution. Moreover, taurine prevents liver damage from a variety of drugs and, thus, protects the liver. Taurine is involved in the development and function of the retina and lens. It also has anti-atherosclerotic and anti-thrombotic effects that protect against cardiovascular disease. Taurine may have additional physiological functions, and warrants further investigation.

        Taurine is one of the most abundant free β-amino acids in the human body that accounts for 0.1% of the human body weight. It has a sulfonic acid group in place of the more common carboxylic acid group. Mollusks and meat are the major dietary source of taurine, and mother`s milks also include high levels of this amino acid. The leukocytes, heart, muscle, retina, kidney, bone, and brain contain more taurine than other organs. Furthermore, taurine can be synthesized in the brain and liver from cysteine. There are no side effects of excessive taurine intake in humans; however, in case of taurine deficiency, retinal abnormalities, reduced plasma taurine concentration, and other abnormalities may occur. Taurine enters the cell via a cell membrane receptor. It is excreted in the urine (approximately 95%) and feces (approximately 5%). Taurine has a number of features and functions, including conjugation with bile acid, reduction of blood cholesterol and triglyceride levels, promotion of neuron cell differentiation and growth, antioxidant effects, maintenance of cell membrane stability, retinal development, energy generation, depressant effects, regulation of calcium level, muscle contraction and relaxation, bone formation, anti-inflammatory effects, anti-cancer and anti-atherogenic effects, and osmotic pressure control. However, the properties, functions, and effects of taurine require further studies in future.

        Since Korean ancient times, powder of Rosa rugosa Thunberg has been used as a folk remedy. This study was conducted to verify the effects of Rosa rugosa Thunberg powder on in vitro antioxidant properties and serum lipid levels of high-fat diet-induced mice from a nutritional viewpoint. In the case of Rosa rugosa Thunberg powders, measurement of TPC, ABTS radical scavenging activity of trolox, DPPH radical scavenging activity, and measured value of FRAP were higher in ethanol extract than water extracts. For LDL-cholesterol concentration, mice fed 10% powder of Rosa rugosa Thunberg with high-fat diets showed a high numerical value compared with other groups (p<0.05). When testing for triglyceride concentrations in blood, mice fed 10% and 20% powder of Rosa rugosa Thunberg with high-fat diets showed the lowest numerical values (p<0.05). When testing for blood insulin concentrations, the high-fat diet group showed higher levels than compared to the control group (p<0.05). When testing for blood leptin concentrations, the high-fat diet group was 5.88±3.53 ng/dL, whereas mice fed 10% powder of Rosa rugosa Thunberg with high-fat diets showed a blood leptin level of 10.36±5.96 ng/dL (p<0.05). Therefore, results prove that powder of Rosa rugosa Thunberg reduces triglyceride concentrations in the blood, and could be used as an excellent natural antioxidant in the future.
