Investigators are interested in learning how appetite responds to pasta containing different amounts of protein and fiber. In this research study, subjects will be asked to eat as much as they want of pasta containing different amounts of protein and fiber mixtures, thereafter subjects will describe their feelings of hunger, fullness and desire to eat for 3 hours afterwards. Subjects will be asked to do this on three separate occasions.
The study is a randomized, 3-arm, treatment-controlled, within-subjects, 3-hour postprandial crossover study to evaluate the satiation effects of pasta formulations on lunch intake in healthy weight women. The study design will test 3 varying pasta formulations (2 experimental and 1 standard control) in a lunch setting in relatively healthy unrestrained women.
This study will require one initial screening visit (approximately 1 hour) and three study visits each lasting approximately 4 hours. All visits should be done in 1 month. We are looking for healthy, non-smoking women older than 18 years of age with no significant medical history.
The initial screening visit will determine subject eligibility through height, weight and waist circumference measurements, blood glucose test (finger prick) and eating, health, exercise and mood surveys.
If willing and eligible to participate, subjects will have 3 study visits. At each visits, subjects will be asked to consume as much as they would like of the pasta meal and beverage in a lunch setting and thereafter will be followed for 3 hours assessing subjective feelings of satiety. The lunch meal will be provided 5 hours after a standardized breakfast (usual breakfast for each subject at the same time of day on each study visit day). During the course of the study, subjects will be instructed to maintain their usual level of activity and diet. Four day food records will be maintained throughout the course of the study.

The aim of this clinical study is to investigate and compare the postprandial glycemic response to three different meal types rich in carbohydrates, that is, white pasta, high protein past...
This controlled weight loss trial in adults at cardiometabolic risk (elevated triglyceride/HDL ratio) followed a randomized, cross-over design and utilized novel, high-protein pasta and ce...
To the best of our knowledge, the effect of pasta consumption within a hypocaloric Mediterranean diet has only been scarcely explored yet. Therefore, a two-parallel group dietary intervent...
Pasta is an important example of a food which can lower the glycemic index (GI) of the diet, a property that has been exploited extensively in studies of low GI dietary patterns. Although ...
The intervention was preceded by a 1-week run-in period during which participants underwent continuous glucose monitoring (CGM) and filled in a 7-day dietary record to optimize basal infus...
Dietary fiber and whole grain foods may contribute to the regulation of appetite; however, evidence has produced inconclusive findings. The objective was to evaluate the effects of an experimental who...
The consumption of whole-grain food-including pasta-has been increasing steadily. In the case of whole-grain pasta, given the many different producers, it seems important to have some objective parame...
Significant reductions in insulin resistance (IR) can be achieved by either calorie restriction or by the increase of lean mass. However, calorie restriction usually results in significant loss of lea...
Fresh pasta is highly susceptible to microbial contamination because of its high water activity and nutrient content. In this study, a new biopreservation system was examined that consists of an activ...
The activity of the PrkC protein kinase is regulated in a sophisticated manner in Bacillus subtilis cells. In spores, in the presence of muropeptides, PrkC stimulates dormancy exit. The extracellular ...
A member of the Wiskott-Aldrich syndrome protein family that is found at high levels in NERVE CELLS. It interacts with GRB2 ADAPTOR PROTEIN and with CDC42 PROTEIN.
A bone morphogenetic protein that is found at high concentrations in a purified osteoinductive protein fraction from BONE. Bone morphogenetic protein 3 is referred to as osteogenin, however it may play a role in variety of developmental processes.
Liquid chromatographic techniques which feature high inlet pressures, high sensitivity, and high speed.
The second most abundant protein component of HIGH DENSITY LIPOPROTEINS or HDL. It has a high lipid affinity and is known to displace APOLIPOPROTEIN A-I from HDL particles and generates a stable HDL complex. ApoA-II can modulate the activation of LECITHIN CHOLESTEROL ACYLTRANSFERASE in the presence of APOLIPOPROTEIN A-I, thus affecting HDL metabolism.
Myeloid-lymphoid leukemia protein is a transcription factor that maintains high levels of HOMEOTIC GENE expression during development. The GENE for myeloid-lymphoid leukemia protein is commonly disrupted in LEUKEMIA and combines with over 40 partner genes to form FUSION ONCOGENE PROTEINS.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
