“…The higher consumption of MUFA and PUFA corroborates previous studies (Hawk, Englehardt & Small, 2012;Kristensen et al, 2015) as well as the higher ratio of unsaturated to saturated fatty acids (Majewska et al, 2016) and fiber intake (Vinagre, Vinagre, Pozzi, Zacari & Maranhao, 2014). However, no influence of this dietary pattern on plasma concentrations of total cholesterol were noted between the groups, contradicting studies that evidence this tendency when food of animal origin is restricted (Santos et al, 2013;Vinagre et al, 2014;Wang et al, 2015).…”

“…Findings regarding lipid profile, mainly HDL-c, in vegetarian groups are controversial. While some authors found no differences between vegetarians and non-vegetarians (Cedo et al, 2015;Santos et al, 2013;Vinagre et al, 2014) another study showed a significantly lower value of this parameter in vegetarians (Huang et al, 2012). Wang et al (2015) in a systematic review and meta-analysis showed that vegetarian diets, compared with omnivorous diets, improve therapeutic targets for cardiovascular disease risk reduction, including LDL-c.…”

This study investigated whether university students following a vegetarian diet differed from non-vegetarian students in nutrient intake, biochemical, hematological and blood mineral profile of nutritionally relevant elements. In total, 107 students from a university, following either a non-vegetarian or a vegetarian diet for at least 1 year prior to the study, were recruited in two stages, setting up two experiments. Nutrient intake (experiment 1, n = 58), and biochemical and hematological parameters (experiment 2, n = 49) were evaluated. TXRF spectroscopy was used for determination of trace elements in whole blood. Vegetarians showed differences in nutrient intake, mainly higher consumption of unsaturated fatty acids and fiber. No significant differences in the biochemical and hematological parameters were found. The prevalence of abnormal parameters in a considerable number of vegetarians and non-vegetarians were found, mainly regarding high density lipoprotein (HDL-c) and total cholesterol (TC). TXRF spectroscopy proved to be a simple tool for determining nutrition-relevant elements (K, Fe, Cu and Zn) in blood samples. The high incidence of abnormal parameters, regardless of the dietary pattern, raises concern about the high prevalence of bad eating habits among young university students. Particularly for the vegetarian students, these results may partly counteract the beneficial lifestyle of a vegetarian diet evidenced by previous studies. It is important for students to be aware of its potential nutritional limitations. In this context, food and nutrition education programs in the academic context could contribute to set up autonomous and healthy subjects, regardless of the diet chosen.

“…In the subject of vegetarians, FCR cholesterol esters are five times higher than nonvegetarian, this indicates that the residual clearance of plasma kilomycron in vegetarians is more effective than nonvegetarian. The results of the study contradict the study of Lee et al, (2016) which states that there are no significant differences in total cholesterol levels between vegetarians and nonvegetarians, this is due to consumption of some food items that are still allowed in certain vegetarian groups such as vegetarian lacto ovo and ovo consuming eggs, while egg yolks are known to be one of the foods that are high in cholesterol, besides milk and milk products also contribute to the intake of saturated fatty acids and cholesterol (Vinagre et al, 2014).…”

“…Vegetarian diets have a tendency to be low in saturated fatty acids (SFA) and rich in polyunsaturated fatty acids (PUFAs) which are known to have good effects on fat metabolism (McEvoy, Temple & Woodside, 2012). Vinagre et al, (2014) also suggested that the substitution of SFA with PUFA and MUFA would reduce LDL cholesterol levels through a mechanism to increase the expression of LDL receptors in liver cells and take leftover cholesterol by the liver. In a study by Vinagre et al, (2014) there were significant differences between Fraction Clearance Rate (FCR) cholesterol ester emulsions for vegetarians and nonvegetarians.…”

Total cholesterol level is one of the risk factor of cardiovascular disease. The proportion rate of hypercholesterolemia in Indonesia remains high, numbering around one third of (35.9%) Indonesians. Hypercholesterolemia is a modifiable risk factor, one of early measures that can be taken to prevent hypercholesterolemia is nutritional intervention. A dietary pattern high in plant sources and lower fat consumption has been recommended by several health organisation for prevention of hypercholesterolemia. This study was intended to determine mean difference of cholesterol level between vegetarian and nonvegetarian in Maha Vihara Maitreya Duta Palembang. This was an observational analytical study with cross-sectional design. A total of 173 subjects at Maha Vihara Maitreya Duta Palembang was included which consist of 80 Vegetarian and 93 Nonvegetarian. Measurement of total cholesterol level was done using rapid diagnostic test (RDT) Autocheck® Multi Monitoring System and parametric Independent T Test was chosen as method of statistical analysis. p<0.001 indicates significant differences of total cholesterol level between vegetarian (172.51± 39.05 mg/dL) and nonvegetarian (228.67±68.07 mg/dL) groups. The mean differences of total cholesterol of vegetarian group is 56,16 mg/dl lower than non vegetarian groups. A significant differences exist in total cholesterol level between vegetarian and non vegetarian group at Maha Vihara Maitreya Duta Palembang. Vegetarian groups has lower total cholesterol level compared to nonvegetarian.

“…In vitro post-heparin lipoprotein lipase (LPL) activity in the plasma was determined after 12 h fasting on the day after the kinetic studies [ 16 , 17 ], using as substrate a chylomicron-like emulsion labeled with glycerol tri[ 3 H] oleate. The plasma samples, collected 10 minutes after an injection of heparin (10U/kg BW), and the emulsion were incubated at 37°C for pre-established intervals during 180 min.…”

Removal of Chylomicron Remnants from the Bloodstream is Delayed in Aged Subjects

et al. 2018

Dietary fats absorbed in the intestine are transported in the circulation as chylomicrons and remnants that have atherogenic potential. Although postprandial lipidemia is increased in older subjects, the specific chylomicron metabolism has not been explored in older subjects nor compared to young subjects, which is the focus of this study. After a 12 h fast, artificially-made emulsions similar to lymph chylomicrons and doubly labeled with radioactive cholesteryl esters and triglycerides were intravenously injected in 23 older (66±4 years) and 20 young (24±3 years) subjects. Sequential blood samples were collected to determine fractional clearance rates (FCR, in min-1) by compartmental analysis. Older subjects had higher LDL-cholesterol (p<0.001) and triglycerides (p<0.0001) than young subjects; HDL-cholesterol presented no difference. The emulsion cholesteryl-ester FCR was lower in older subjects compared to the young (p=0.0001). The emulsion triglyceride FCR did not differ in the two groups. Tested in vitro, however, the lipolysis of the emulsion triglycerides was less intense in the older than in the young subjects. As delayed removal of remnants, indicated by the pronouncedly smaller cholesteryl ester FCR, is related to the presence of cardiovascular diseases, this can be a risk factor which could accelerate atherogenic complications occurring in aged subjects

Plasma kinetics of chylomicron-like emulsion and lipid transfers to high-density lipoprotein (HDL) in lacto-ovo vegetarian and in omnivorous subjects

Abstract: Similarly to vegans, lacto-ovo vegetarian diet increases remnant removal, as indicated by cholesteryl oleate FCR, which may favor atherosclerosis prevention, and has the ability to change lipid transfer to HDL.
