Plasma Triacylglycerol

There is concern that replacement of dietary fat with carbohydrate may not reduce the overall risk of CHD because this replacement strategy elevates postprandial plasma triacylglycerol (TAG) concentrations. The present study was designed to test the hypothesis that daily exercise can offset the augmented postprandial lipaemia associated with a short-term high-carbohydrate diet. Nine healthy, normolipidaemic men aged 33 (SD 4) YEARS CONSUMED A TEST MEAL (G/KG BODY MASS; 1·2 FAT, 1·1 CARBOHYDRATE, 0·2 PROTEIN) ON THREE OCCASIONS: AFTER 3 D ON A TYPICAL WESTERN DIET (46, 38 AND 16 % ENERGY FROM CARBOHYDRATE, FAT AND PROTEIN RESPECTIVELY); AFTER 3 D ON AN ISOENERGETIC HIGH-CARBOHYDRATE DIET (CORRESPONDING VALUES: 70, 15 AND 15 % ENERGY); AFTER 3 D ON THE SAME HIGH-CARBOHYDRATE DIET WITH 30 MIN MODERATE EXERCISE DAILY. FASTING PLASMA TAG CONCENTRATION WAS HIGHER AFTER THE HIGH-CARBOHYDRATE DIET (1·15 (se 0·16) mmol/l) than after the Western diet (0·83 (se 0·10) mmol/l; P=0·03). Similarly, postprandial lipaemia (6 h total area under plasma TAG concentrationv.time curve) was higher after the high-carbohydrate diet (12·54 (se 2·07) mmol/l·h) than after the Western diet (9·30 (se 1·30) mmol/l·h; P=0·004). The addition of exercise to the high-carbohydrate diet significantly reduced postprandial lipaemia (9·95 (se 1·94) mmol/l·h; P=0·01 when compared with the high-carbohydrate diet) but not fasting TAG concentration (1·02 (se 0·24) mmol/l). In conclusion, daily exercise prevented the augmentation of postprandial lipaemia attributable to the short-term high-carbohydrate diet and, thus, exercise may be a powerful adjunct to dietary change.

Corticosterone Treatment

The aim of this study was to examine the effects of short-term corticosterone treatment on brown adipo?cytes of rats overfed with sucrose. Ultrastructural and stereological analysis showed that brown adipocyte components responded to the applied treatment in conformity with their own dynamics and affinity. Although brown adipocytes generally corresponded to thermogenically active cells, some signs of supression of that function, such as mitochondrial degradation and a pattern of lipid accumulation, were noticeable. Taken together, the presented results indicate that a high carbohydrate diet delays the expected inhibitory influence of corticosterone on brown adipose tissue thermogenesis. For the full expression of corticosterone effects, longer treatment is needed.

Rainbow trout are considered as a poor user of dietary carbohydrates, displaying persistent postprandial hyperglycaemia when fed a diet containing high amounts of carbohydrates. While this phenotype is well-described in juveniles, less attention was given to broodstock. Our objective was to assess for the first time the short-term consequences of feeding mature female and male, and neomale trout with a low-protein high-carbohydrate diet on glucose and lipid metabolism. Fish were fed for two days with a diet containing either no or 32% of carbohydrates. We analysed plasma metabolites, mRNA levels and enzymatic activities of glycolysis, gluconeogenesis, de novo lipogenesis and β-oxidation in the liver. Results demonstrated that the glucose and lipid metabolism were regulated by the nutritional status in all sexes, irrespective of the carbohydrate intake. These data point out that carbohydrate intake during a short period (5 meals) at 8 °C did not induce specific metabolic changes in broodstock. Finally, we demonstrated, for the first time, sex differences regarding the consequences of two days of feeding on glucose and lipid metabolism.

We examined the effect of dietary carbohydrate intake on post-exercise glycogen recovery. Male Institute of Cancer Research (ICR) mice were fed moderate-carbohydrate chow (MCHO, 50%cal from carbohydrate) or high-carbohydrate chow (HCHO, 70%cal from carbohydrate) for 10 days. They then ran on a treadmill at 25 m/min for 60 min and administered an oral glucose solution (1.5 mg/g body weight). Compared to the MCHO group, the HCHO group showed significantly higher sodium-D-glucose co-transporter 1 protein levels in the brush border membrane fraction (p = 0.003) and the glucose transporter 2 level in the mucosa of jejunum (p = 0.004). At 30 min after the post-exercise glucose administration, the skeletal muscle and liver glycogen levels were not significantly different between the two diet groups. The blood glucose concentration from the portal vein (which is the entry site of nutrients from the gastrointestinal tract) was not significantly different between the groups at 15 min after the post-exercise glucose administration. There was no difference in the total or phosphorylated states of proteins related to glucose uptake and glycogen synthesis in skeletal muscle. Although the high-carbohydrate diet significantly increased glucose transporters in the jejunum, this adaptation stimulated neither glycogen recovery nor glucose absorption after the ingestion of post-exercise glucose.

Amomum tsao-ko Crevost et Lemaire (Zingiberaceae) is a medicinal herb found in Southeast Asia that is used for the treatment of malaria, abdominal pain, dyspepsia, etc. The aim of this study was to investigate the effect of an ethanol extract of Amomum tsao-ko (EAT) on obesity and hyperlipidemia in C57BL/6 mice fed a high-carbohydrate diet (HCD). First, the mice were divided into five groups (n = 6/group) as follows: normal diet, HCD, and HCD+EAT (100, 200, and 400 mg/kg/day), which were orally administered with EAT daily for 84 days. Using microcomputed tomography (micro-CT) analysis, we found that EAT inhibited not only body-weight gain, but also visceral fat and subcutaneous fat accumulation. Histological analysis confirmed that EAT decreased the size of fat tissues. EAT consistently improved various indices, including plasma levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein, high-density lipoprotein, atherogenic index, and cardiac risk factors, which are related to dyslipidemia—a major risk factor for heart disease. The contents of TC and TG, as well as the lipid droplets of HCD-induced hepatic accumulation in the liver tissue, were suppressed by EAT. Taken together, these findings suggest the possibility of developing EAT as a therapeutic agent for improving HCD-induced obesity and hyperlipidemia.
