Abstract
Diacylglycerol (DAG) has been reported to reduce the serum lipid and glucose levels more effectively compared with triacylglycerol (TAG). The present study examined the long-term effects of dietary DAG on rats with type 2 diabetic nephropathy (DN). The type 2 DN model was established by administering a high-fat and high-calorie diet along with an intraperitoneal injection of 35 mg/kg body weight streptozocin, and the disease developed over the following 8 weeks. Sprague-Dawley rats were then randomly divided into the control, TAG, low-dose DAG (Low-DAG) and high-dose DAG (High-DAG) groups. Blood glucose (BG), lipid levels and renal function parameters were then measured. The results revealed that the body weight in the High-DAG group was significantly reduced compared with the TAG group, while there was no significant difference in the food intake between TAG and DAG groups. BG, advanced glycation end products (AGEs), TAG, low-density lipoprotein cholesterol, urine protein and urine albumin levels were significantly reduced, while high-density lipoprotein cholesterol levels were significantly increased in the two DAG groups. In addition, hematoxylin-eosin stained glomeruli presented decreased glomerular enlargement and mesangial expansion in the DAG groups. Immunohistochemical detection revealed that the levels of transforming growth factor-β1 and connective tissue growth factor in renal tissues of the DAG groups were also significantly reduced compared with the TAG group. These findings indicate that DAG oils can significantly reduce BG levels and the deposition of AGEs in renal tissue, as well as regulate the levels of transforming growth factor-β1 and connective tissue growth factor, thus delaying the progression of nephropathy.

Substitution of TAG oil with diacylglycerol oil in food items improves the predicted 10 years cardiovascular risk score in healthy, overweight subjects. J Nutr Sci 2012; 1:e17. [PMID: 25191546 PMCID: PMC4153080 DOI: 10.1017/jns.2012.18] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2012] [Revised: 08/24/2012] [Accepted: 09/04/2012] [Indexed: 01/07/2023] Open
Abstract
Dietary fat is normally in TAG form, but diacylglycerol (DAG) is a natural component of
edible oils. Studies have shown that consumption of DAG results in metabolic
characteristics that are distinct from those of TAG, which may be beneficial in preventing
and managing obesity. The objective of the present study was to investigate if food items
in which part of the TAG oil is replaced with DAG oil combined with high α-linolenic acid
(ALA) content would influence metabolic markers. A 12-week double-blinded randomised
controlled parallel-design study was conducted. The participants (n 23)
were healthy, overweight men and women, aged 37–67 years, BMI 27–35 kg/m2, with
waist circumference >94 cm (men) and >88 cm (women). The two groups received
20 g margarine, 11 g mayonnaise and 12 g oil per d, containing either high ALA and
sn-1,3-DAG or high ALA and TAG. Substitution of TAG oil with DAG oil in
food items for 12 weeks led to an improvement of the predicted 10 years cardiovascular
risk score in overweight subjects by non-significantly improving markers of health such as
total body fat percentage, trunk fat mass, alanine aminotransferase, systolic blood
pressure, γ-glutamyl transferase, alkaline phosphatase and total fat-free mass. This may
suggest that replacing TAG oil with DAG oil in healthy, overweight individuals may have
beneficial metabolic effects.

Abstract
O objetivo do presente manuscrito foi revisar o possível papel dos lipídeos dietéticos na nefropatia diabética (ND), considerando as alterações do perfil lipídico associadas e a interação entre aspectos dietéticos e genéticos. Os lipídeos dietéticos podem ter um papel importante no desenvolvimento e na progressão da ND. A composição das gorduras da dieta tem sido associada com a ND, particularmente à microalbuminúria e às anormalidades lipídicas e de função endotelial. Entretanto, ainda não está comprovado o benefício da modificação da ingestão de gorduras em pacientes com ND, em especial sobre desfechos definitivos, como incidência e progressão da ND, insuficiência renal e morte. Além disso, a resposta do perfil lipídico à ingestão de gorduras pode ser influenciada por fatores genéticos. A identificação de polimorfismos genéticos específicos associados a essa interação poderá permitir a individualização de estratégias nutricionais na ND.

Dietary diacylglycerol oil has no effect on hypertriacylglycerolaemia in lipoprotein lipase-deficient cats. Br J Nutr 2009; 102:1024-9.

Abstract
A commercially available vegetable oil containing a high concentration (87 %, w/w) of diacylglycerol (DAG) has been investigated in humans and animals for potential beneficial effects in reducing serum TAG concentrations in fasting and postprandial states. Effects of DAG oil as a sole dietary fat source (25 % metabolisable energy) were evaluated in a feline model of hypertriacylglycerolaemia. Eleven adult (1.5 (sem 0.1) years) male cats deficient of lipoprotein lipase (LPL) catalytic activity from a heritable point mutation of the LPL gene were acclimatised to a semi-purified diet containing TAG oil for 21 d. After assignment into two groups, pair-matched by serum TAG concentrations (range 6.1-31.6 mmol/l), the cats were fed the diet with either TAG or DAG oil for 8 d. The dietary fat source was crossed-over and presented for 8 d more. Non-fasting serum concentrations of TAG, cholesterol and NEFA were measured on days 6-8 and days 14-16. Dietary fat source (DAG v. TAG) did not significantly affect food intake (491 (sem 16) v. 486 (sem 14) kJ/kg0.67), body weight or serum concentrations (mmol/l) of TAG (37.1 (sem 4.5) v. 33.9 (sem 3.4)), cholesterol (4.8 (sem 0.3) v. 4.8 (sem 0.2)) and NEFA (1.4 (sem 0.2) v. 1.4 (sem 0.2)). The results show that for a feeding trial of 8 d, DAG oil was well accepted and tolerated by cats but did not reduce hypertriacylglycerolaemia resulting from a deficiency of LPL catalytic activity.

Abstract
BACKGROUND & AIMS Diacylglycerol oil has been shown to lower postprandial and fasting serum triacylglycerol levels and reduce body fat. The aim of this study was to investigate the effect of diacylglycerol oil on risk factors of type 2 diabetes mellitus (DM) and cardiovascular disease in type 2 DM patients. METHODS This was a double-blind controlled parallel study with 127 type 2 DM patients (aged 40-65) recruited in Hangzhou, China. All subjects consumed triacylglycerol oil in the lead-in period (14 days), then they were randomly divided into two groups and consumed diacylglycerol or triacylglycerol oil with a similar fatty acid composition (25 g/day) for 120 days. Blood samples were collected on days 0, 60 and 120 and risk factors of type 2 DM and cardiovascular disease and biochemical parameters were measured by standard methods. RESULTS There were a total of 112 subjects who completed the study. Diet intake did not differ significantly between groups. Body weight, BMI, waist circumference, HOMA-IR, serum insulin and leptin levels were significantly reduced from baseline in the diacylglycerol oil group but not in the triacylglycerol oil group. Serum glucose was also significantly improved in patients with higher glucose levels at baseline (>7.00 mmol/L) in the diacylglycerol oil group. Parameters of liver and kidney functions and essential fatty acids in serum phospholipids did not differ between groups. CONCLUSIONS Diacylglycerol oil consumption improved biomarkers and anthropometric parameters of type 2 DM compared with triacylglycerol oil. No adverse reactions were observed with diacylglycerol oil consumption for type 2 DM patients. Diacylglycerol oil has an equivalent bioavailability as triacylglycerol oil in relation to providing essential fatty acids.
