Fresh pork belly is a highly popular meat in South Korea, accounting for 59 % of the approximately 100 g of meat per capita that is consumed daily. Fresh pork belly offers not only high-quality protein from the lean cuts but also substantial micronutrients including fat-soluble vitamins and minerals. However, fresh pork belly generally consists of about 30 % fat, with saturated fatty acids representing half of this value. Excessive consumption of saturated fatty acids increases total cholesterol, low-density lipoprotein-cholesterol, and triglycerides while decreasing high-density lipoprotein-cholesterol, raising concerns about an increased risk of hyperlipidemia, followed by cardiovascular diseases. In this review, we discuss the consumption and production trends in South Korea, the general characteristics, and health issues related to fresh pork belly to delineate the features of pork production and consumer welfare.

This study intended to compare the effects of the sugar-Omija extract tea (SO) and LuoHanGuo-Omija extract tea (LO) to blood glucose levels and metabolism among streptozotocin (STZ)-induced diabetic mice and to prove the positive effects of LuoHanGuo extract as a sugar substitute. According to the results, the rate of blood glucose increase and the blood glucose level was reduced, and the weight was increased. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride, low density lipoprotein cholesterol, and total cholesterol was decreased, and albumin, total protein, and high density lipoprotein cholesterol (HDL-C) was increased in the STZ/LO group as compared to the STZ group. Compared to the STZ/SO group, the rate of blood glucose increase and glucose tolerance was decreased. AST, ALT, and total cholesterol was decreased, and HDL-C level was high. In conclusion, the LO displayed hypoglycemic effect, prevented weight loss caused by diabetes, recovered liver function, and improved lipid metabolism. In addition, such positive effects were obviously shown during comparison with the experimental group treated with the SO. Therefore, the LO were considered as favorable food supplements that can be safely taken by persons with diabetes, obesity, hypertension, and heart disease; they have to control their sugar intake as well as their diet.

There have been growing interests in olive oil, which is attributed to the beneficial health effects of the Mediterranean diet. Numerous studies suggest that oleic acid, the major fatty acid in olive oil, may contribute to less incidence of coronary heart disease(CHD) in the Mediterranean area. Although the major effects of high monounsaturated fatty acid(MUFA) consumption on lowered plasma cholesterol are generally attributed to the consequential replacement of saturated fatty acid in diets, some studies have shown a modest cholesterol lowering effect of MUFA alone when it replaces dietary carbohydrate at an equal amount of energy. Furthermore, MUFA increases the level of the protective high-density lipoprotein cholesterol more than polyunsaturated fatty acid(PUFA) does when these two classes of fatty acids replace carbohydrates in the diet. It has been generally recommended that optimal dietary fat should be rich in MUFA, such as oleic acid, low in saturated fatty acids and provide adequate amounts of PUFA. However, no conclusive observations have been made yet mainly due to a difficulty in controlling the proportion of oleic acid without adjusting the levels of the other fatty acids to be constant, which could also affect plasma cholesterol levels. Recent findings also suggest that dietary PUFA results in higher tendency toward lipid peroxidation whereas with MUFA the susceptibility of low density lipoprotein to oxidative stress is reduced. More studies are needed to clarify the effects of MUFA on reducing the incidence of CHD.

Three herbal medicine recipes were tried on the animal model of diet induced hypercholesterolemia to screen for the lipid-lowering effect. The recipes adopted were based on the prescription for atherosclerosis-related symptoms by folk-medicine practioners. Hyperlipidemia was induced in rats by giving the high lipid/cholesterol diet for 7 days. Then, the recipes started with the normal diet. Blood was sampled at 1,2,3 and 5 week-points of the treatment, and levels of total cholesterol, triglyceride, high density lipoprotein and lower density lipoprotein were measured. Dae-shiho-tang decreased total cholesterol level significantly. Hwangryun-haedok-tang and Samhwang-sasim-tang slightly decreased total cholesterol level, although it was not statistically significant.

The lowering effect of cholesterol in Sprague Dawley rats was investigated with panaxydol which was purified from the petroleum ether soluble fraction(PESF) of Korean red ginseng. The level of total cholesterol(TC), Triglyceride(TG) and low density lipoprotein(LOL)-cholesterol in serum was reduced by $48\%,\;47\%\;and\;41\%,$ respectively while high density lipoprotein(HDL)-cholesterol was in creased up to $29\%$ as compared with their control values when the panaxydol(20 umoles. 5 mq/kq/day) was adminstered by intraperitoneal rout for 3 consecutive days along with a $1\%$ cholesterol diet. The hepatic ester cholesterol content which was increased in proportion to the cholesterol content of the diet in the control, clearly decreased with panaxydol administration to about $40\%$ regardless of the two diet cholesterol content. $1\%\;or\;2\%.$ A threshold of supression on the serum lipid levels in both administration routes was observed: the maximium suppression in i.p. and p.o. administration was observed to be at 5mq/kq b.w. and in the range of 50 - 100 mg/kg b.w., respectively. Panaxydol may reduce serum lipid and cholesterol levels by inhibiting cholesterol absorption and/or by modulating the cholesterol metabolism. at least in part.

Since the effects of cinnamon supplementation on lipid profiles are still controversial, this study conducted a meta-analysis of randomized controlled trials to assess the effect of cinnamon supplementation on lipid profiles. The study was designed and conducted according to the guidelines of the 2020 preferred reporting items for systematic reviews and meta-analysis (PRISMA) statements. A systematic and comprehensive search was performed in several databases from inception up to 11 November 2023. The meta-analysis on the impact of Cinnamon on lipid profiles indicates a non-significant overall effect on low-density lipoprotein (weighted mean differences [WMD], -2.48; 95% confidence interval [CI], -9.70, 4.72). However, significant reductions are seen with doses < 500 mg/day (-10.26), and non-significant increases with doses ≥ 500 mg/day (1.18). The overall effect on high-density lipoprotein is non-significant (WMD, 3.97; 95% CI, -7.877, 15.831), showing varying responses at different doses. Triglycerides exhibit a significant overall reduction (WMD, -6.88; 95% CI, -12.62, -1.15), particularly in the < 500 mg/day group. The overall effect on cholesterol is non-significant (WMD, -4.314; 95% CI, -15.011, 6.384), with diverse responses at different doses. High heterogeneity underlines the importance of standardized study designs and further exploration of dosage-specific effects. Findings from this study suggest that cinnamon supplements might be beneficial to modulate the blood lipid profile.

계란의 난황으로부터 유래한 IgY의 분리와 정제과정이 흐름을 정리한 결과, 난황에서의 수용성 단백질의 분리단계가 단백질의 수율을 증가시키는데 가장 큰 영향을 미치는 것으로 판단되었다. 본 연구에서는 자연 침전방법을 통하여 실험하였는데 수율의 증가를 위해서는 원심분리와 같이 수용성 단백질의 양을 많이 얻을 수 있는 방법이 필요하고, 인지질이나 lipoprotein등의 성분의 제거효율을 높이기 위해서는 x-carrageenan등과 같은 natural gum성분의 첨가와 같은 방법이 필요하다. 그러므로 자연침전을 이용하여 수율의 증가측면과 비용의 절감의 효과를 얻을 수 있었다. 보다 효율적인 IgY의 분리를 위해서는 초기 단계에서 수율의 극대화와 불순성분 제거의 최대화가 동시에 요구되고 있다. 전처리 후의 시료를 이용하여 이온교환 크로마토그래피와 gel filtration chromatography를 통해 순도 90% 이상의 IgY를 얻을 수 있었다.

This study compared the lipid metabolism of white Leghorn layers between the growing and the laying periods. The study was conducted on thirty layers in the growing period (14 weeks old) and in the initial laying period (36 weeks old; 14 weeks from the onset of laying). Results indicated that all plasma lipid traits were significantly different (p<0.05) between the two periods. The estrogen concentration in the laying period was about 3 fold that in the growing period. Triacylglycerol (TG) concentration in the laying period was about 12 fold that in the growing period. The phospholipids, cholesterol, glycerol and non esterified fatty acid (NEFA) in the laying period were also higher than those in the growing period (p<0.05). Lipogenic enzyme activities in the laying period were higher than in the growing period (p<0.05). High-density lipoprotein (HDL) was the largest lipoprotein portion in growing layers. In laying hens, the major lipoprotein portion was very low-density lipoprotein (VLDL). It was also shown that protein is the primary component of HDL and TG is the largest portion of VLDL in both periods. In laying hens, VLDL contained more TG than that in growing layers (p<0.05). The VLDL particle size in laying hens was larger than that in growing layers (p<0.05). This study indicates that the lipid metabolism traits of a layer in the laying period were different from those in the growing period. The lipogenesis related traits in the laying period were markedly greater than in the growing period.
