According to the Food and Agriculture Organization, fermentation of fiber by gut microflora is an efficient digestive process where more than half of consumed dietary fiber is degraded in the large intestine. The specific behavior of this indigestible plant material is defined by its physical properties, which dictate its health benefits and journey through the digestive system.

Most unopened energy gels are designed to be shelf-stable and do not require refrigeration for food safety. However, many athletes wonder: can I put energy gels in the fridge to make them more refreshing during a hot-weather workout?

Psyllium husk, a soluble fiber derived from the seeds of the Plantago ovata plant, can absorb up to 16 times its dry volume in water. It is this incredible water-absorbing ability that answers the question: is psyllium husk thick? The resulting thick, viscous gel is not just a scientific curiosity but a functional property with wide-ranging uses, from improving digestive health to revolutionizing gluten-free baking.

According to research published in the *Nutrition Journal*, the high viscosity created by oat beta-glucan is linked to significant health benefits, including lower cholesterol and improved satiety. Understanding this unique property reveals why your morning bowl has that characteristic thick, creamy texture.

According to the U.S. Food and Drug Administration (FDA), tomato juice is officially defined as a "liquid extracted from mature tomatoes". However, its thick texture often raises questions about its classification, especially when compared to simpler liquids like water.

According to the International Dysphagia Diet Standardisation Initiative (IDDSI), a global framework, an "extremely thick" liquid is classified as Level 4, which is the consistency of a pudding or mousse and is spoon-eaten, not sipped. Understanding this level requires a look into the science of viscosity and rheology, defining how substances resist flow across different fields, from healthcare to manufacturing.

Over 90% of commercially produced chocolate contains added emulsifiers to achieve a smooth, consistent texture. However, the notion that all chocolate contains emulsifiers is a common misconception, particularly as artisanal and 'clean label' chocolate brands gain popularity. Some premium chocolates deliberately omit these additives, relying on high-quality ingredients and meticulous processing instead.

According to the Canadian Air Transport Security Authority (CATSA), yogurt is considered a non-solid food and must be in containers of 100 ml or less for carry-on baggage. This raises the intriguing question: is yogurt classed as liquid by scientific or culinary standards as well?

The viscosity of water at 20°C is approximately 1 centipoise, making it a standard for comparison. To accurately check liquid thickness, it's crucial to understand that 'thickness' refers to the scientific property of viscosity, which can be measured using both simple at-home techniques and advanced laboratory instruments.

While some ingredients can perform both functions, an emulsifier is fundamentally different from a thickener due to its primary chemical role. Emulsifiers stabilize mixtures of immiscible liquids, like oil and water, while thickeners simply increase the viscosity of a substance.
