High fat diet on triglycerides journal pdf

Our aims were to examine TRL response to three whole food diets with varying amounts and types of dietary fat high fat, low fat and low fat supplemented with n-3 fatty acidsand to investigate the role of DNA polymorphisms in FABP2 in modifying the TRL response.

The gut microbiota composition of the animals of each group was evaluated at the end of the study by real-time PCR. A particularly striking observation was that two general patterns of de novo lipogenesis were observed throughout the day: The mechanism by which n-3 lower triglycerides is unclear, however research suggests that n-3 binds to nuclear receptors, such as peroxisome proliferator activator receptors PPARsand decreases hepatic triglyceride and VLDL synthesis and secretion [ 13 ].

The second source of fatty acids for VLDL-TG synthesis, de novo lipogenesis, could be stimulated by an excess flow of glucose through the glycolysis pathway and into the hepatic acetyl coenzyme A pool.

To assess some of the features of the metabolic syndrome, oral glucose tolerance tests, systolic blood pressure measurement, and blood biochemical analysis were performed. In contrast to the chylomicron-TG data, chylomicron apolipoprotein apo B48 concentrations were significantly elevated after meals with a high glycemic index meals compared with those with a low glycemic index.

Studies are also needed to assess the contribution of de novo lipogenesis to HPTG in adults with insulin resistance. Increases in dietary carbohydrates lead to elevations in both fasting and postprandial lipemia Numerous studies have investigated the effects of alterations in dietary carbohydrate on fasting blood TG concentrations 1.

Thus, against this higher load of TG in the blood in the fasting state, further addition of TG after absorption of a fatty meal lead to significantly higher postprandial TG concentrations. Delineating whether the elevation in blood TG is due to production or clearance is important because these two situations can have very different ramifications with respect to cardiovascular risk.

These data demonstrate that certain characteristics e. Complete details of the dietary treatments are described in the paper by Young [ 14 ]. Two candidate sources have been investigated: We measured the contribution of both free fatty acids and de novo lipogenesis to VLDL-TG synthesis in healthy men before and after 5 wk of isoenergetic, high carbohydrate feeding in which the diet was rich in polysaccharides complex carbohydrates and high in fiber.

The T54 allele has a greater affinity for long chain fatty acids than the A54 allele and results in a greater flux of fatty acids across the enterocytes and into the plasma [ 8 ]. These data suggest that in healthy subjects, some other variable besides glucose or insulin concentration is directly related to increased lipogenesis, or, if higher postprandial glucose or insulin concentrations are the root cause of increased lipogenesis, there exists an intermediary effector translating this signal in the liver.

Aside from pointing out that this diet stimulated de novo lipogenesis, the reader is referred to that publication to appreciate the large variability among subjects in the amount of de novo lipogenesis.

FABP2 is expressed in the enterocytes of the intestine and aids in the absorption and transportation of long chain fatty acids. Dietary fat, Omega-3 fatty acids, Fatty acid binding protein 2, Triglyceride rich lipoprotein, Single nucleotide polymorphisms, Women 1.

Briefly, in a complete feeding study, the subjects were provided each of three isoenergic, controlled diets: No clinical characteristics were found that would distinguish the subjects in the constant or diurnal groups.

High-fat diet-induced obesity Rat model: a comparison between Wistar and Sprague-Dawley Rat

However, a direct comparison between Wistar and Sprague-Dawley SD Rat as models of high-fat HF diet-induced obesity has not been adequately evaluated so far. HF diet showed significantly reduced plasma triglycerides TGchylomicron TG, and very-low density lipoprotein TG from baseline in all participants.Triglycerides are a type of fat in your blood.

Having a high level may raise the risk of heart disease, especially in women.

• you eat excess fat in your diet. • they are released from the fat already stored in your body. High levels of triglycerides in your blood can increase the chance that you develop heart disease. Triglycerides do not build up in the arteries like bad cholesterol (LDL).

Instead, high levels can make LDL cholesterol change into a more harmful form that damages the arteries. High.
