In our previous study, we demonstrated that retrograded starch, a kind of resistant starch, of beans reduced serum lipid levels in rats. In this study, we examined whether retrograded starch in potato pulps could reduce serum lipid concentrations. Rats were given diets containing 15 g of retrograded
BACKGROUND
Olestra, a nonabsorbable, energy-free fat substitute used in snack foods, has been anecdotally reported to cause gastrointestinal (GI) adverse events, although such effects were not expected based on results from randomized trials, in which it was consumed in typical snack
Suberized cell walls from wound-healing potato tubers ( Solanum tuberosum ) were depolymerized under mild conditions using methanolic potassium hydroxide in order to investigate the chemical linkages present in this protective plant biopolymer. Analysis of the resulting soluble oligomeric fragments
Nutritional value of diets containing 10% potato fibre or cellulose (diets MPF and MC, respectively) and their long-term effects on parameters related to potential health benefits were studied in rats. In a first experiment nutrient digestibility and metabolisable energy of the diets were
Colorado potato beetle, Leptinotarsa decemlineata (Say), is an important pest of potato throughout the world. Here, the effects of six potato cultivars including 'Arinda,' 'Sprit,' 'Markiez,' 'Lotta,' 'Santae,' and 'Agria' were studied on nutritional indices, digestive enzymes, and some components
OBJECTIVE
In normal subjects, ingestion of fat with potato in a morning meal resulted in a decrease in the glucose response. Therefore, we wished to determine whether a fat-induced decrease in blood glucose also would be observed after a second identical meal. In addition, we were interested in
Potato starch is known to have a higher concentration of phosphate than other starches. The presence of phosphate groups in amylopectin results in resistance to digestion by amylase. Therefore, there is a possibility that potato starch is slowly digested, inducing a physiological effect similar to
This study was performed to assess the effects of potato protein and fish protein on concentrations of lipids in plasma and lipoproteins and the expression of genes involved in lipid metabolism in pigs used as an animal model. Therefore, 27 young male pigs with an average body weight of 22 kg were
Dietary plant and animal peptides have been shown to reduce serum lipids. However, the potential of food-derived peptides has yet to be fully elucidated. We investigated the physiological importance of potato peptides in rats fed on a cholesterol-free diet containing 20% potato peptides (PP), when
OBJECTIVE
In normal subjects, ingestion of butter with potato resulted in considerably lower blood glucose levels but similar or higher insulin concentrations compared with those observed in the same subjects after potato ingestion alone. We determined whether butter ingested with potato would
The effect of uncooked potato starch in the diet on cecal fermentation and absorption of volatile fatty acids and on changes in the digestive supply of nutrients were investigated. Dietary potato starch (25%) markedly increased cecal size and the cecal pool of volatile fatty acids. These were
An enzyme preparation that catalyses the deacylation of mono- and di-acyl phospholipids, galactosyl diglycerides, mono- and di-glycerides has been partially purified from potato tubers. The preparation also hydrolyses methyl and p-nitrophenyl esters and acts preferentially on esters of long-chain
Ten normal subjects were given 50 g starch, or 50 g starch + 50 g fat as a breakfast meal. The starch was given in the form of potato; the fat was given in the form of butter. The meals were ingested at 8 a.m. Plasma glucose, insulin, C-peptide, and triglyceride concentrations were measured at
Through forward genetic screening in the mouse, a recessive mutation (couch potato, cpto) has been discovered that dramatically reduces plasma cholesterol levels across all lipoprotein classes. The cpto mutation altered a highly conserved residue in the Src homology domain 3 (SH3) domain of the Mia2
Recent evidence indicates that the inhibition of hepatocyte apoptosis is possible to develop a potential therapeutic strategy for nonalcoholic fatty liver disease (NAFLD). Our previous work suggested that purple sweet potato color (PSPC), a class of naturally occurring anthocyanins,
