We assessed fiber intakes and determined the major food categories that contribute to dietary fiber intakes in the Taiwanese elderly. We also examined the association between fiber intake and health status. ⋯ Elderly subjects had remarkably low dietary fiber intakes (g and g/Mcal). Swallowing and chewing ability determined the amount of fiber consumed. Vegetable contributed more than half of dietary fiber intake. The selection of food groups exerted sex-dependent pattern in grains, vegetables, and snacks.

Recent evidence has shown that circulating levels of insulin-like growth factor-I (IGF-I) and leptin are regulated by nutrition support. Our objective was to investigate the reliability of IGF-I and leptin in monitoring the efficacy of nutrition support and nutrition status in oral tumor patients. ⋯ Our results suggested that simultaneous measurements of serum IGF-I and leptin may provide information with regard to the efficacy of nutrition support and nutrition status in oral tumor patients undergoing surgery.

To investigate the effect of two types of dietary protein on blood pressure, liver fatty acid desaturation and composition, and urine 6-keto-prostaglandin-F (PGF(1alpha)) level, the metabolite of prostacyclin. ⋯ The present data indicated a significant blood pressure-lowering effect caused by fish protein, rather than by casein, that modified the fatty acid composition of liver phospholipids and liver microsomal total lipids.

Heart and blood pressure adaptations in Wistar rats fed with different high-fat diets for 18 months.
We investigated the effect of long-term administration of four different high-fat diets on systolic blood pressure (SBP), body and heart biometry, and left ventricular myocyte nuclei number (N[lvm]). ⋯ Long-term intake of the CA diet was more efficient in maintaining normal N(lvm) and SBP than the S and LE diets. The CA + LE diet resulted in balanced levels of SBP and N(lvm) in rats, suggesting that canola oil reduces cardiovascular injury caused by intake of lard and egg yolk.
