One obvious property difference between energy-yielding beverages and solid foods is the oral mechanical processing required to prepare the two food forms for swallowing. Considerable human data are consistent with a contribution of mechanical stimulation to appetite suppression. However, no study has isolated this property and assessed its influence on ingestive behavior in humans. This is the aim of the present study. The null hypothesis is that food rheology will have no effect on these indices. The alternate hypothesis is that increased mechanical stimulation will result in stronger satiation/satiety and reduced energy intake. Further, it is hypothesized that the effects of mastication will be less evident in obese compared to lean individuals.
Allocation: Randomized, Control: Uncontrolled, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Basic Science
The Null Hypothesis is That Food Rheology Will Have no Effect on These Indices.

When a single gene influences more than one trait, known as pleiotropy, it is important to detect pleiotropy to improve the biological understanding of a gene. This can lead to improved screening, dia...
A genus of CYANOBACTERIA consisting of trichomes that are untapered with conspicuous constrictions at cross-walls. A firm individual sheath is absent, but a soft covering is often present. Many species are known worldwide as major components of freshwater PLANKTON and also of many saline lakes. The species ANABAENA FLOS-AQUAE is responsible for acute poisonings of various animals.

Exposure of FOOD to radioactive substances, distinguishable from FOOD IRRADIATION, a food preservation technique.
Any food that has been supplemented with essential nutrients either in quantities that are greater than those present normally, or which are not present in the fortified food. The supplementation of cereals with iron and vitamins is an example of fortified food. Fortified food includes also enriched food to which various nutrients have been added to compensate for those essential nutrients removed by refinement or processing. (From Segen, Dictionary of Modern Medicine, 1992)
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism ...
