The postprandial period is the metabolic phase that directly follows the ingestion of a meal. This period is critical to the handling of nutrients to feed the body throughout the whole day but it is also a time of challenge for the body’s metabolism, which has to be flexible and adaptable regarding the quantity and the quality of the nutrient intake. Changes in postprandial metabolism have been considered to be potential early markers in the pathophysiological course, finally leading to an increased risk of disease development. This book aimed to broaden and add to the research on the importance of postprandial metabolism in nutrition. The book includes literature reviews that cover the broad state of the art of our knowledge about postprandial metabolism, fine original studies of the complex changes in metabolism, and the physiological processes that are considered to drive the onset of pathogenesis. Finally, a series of examples on how nutrient content (especially proteins, sucrose, and lipids) can influence the postprandial metabolism over a wide range of phenomena operating during the postprandial period and how they could contribute to tipping the body towards adverse health processes.

This book, as a collection of 17 research articles, provides a selection of the most recent advances in the synthesis, characterization, and applications of environmentally friendly and biodegradable biopolymer composites and nanocomposites. Recently, the demand has been growing for a clean and pollution-free environment and an evident target regarding the minimization of fossil fuel usage. Therefore, much attention has been focused on research to replace petroleum-based commodity plastics by biodegradable materials arising from biological and renewable resources. Biopolymers—polymers produced from natural sources either chemically from a biological material or biosynthesized by living organisms—are suitable alternatives for addressing these issues due to their outstanding properties, including good barrier performance, biodegradation ability, and low weight. However, they generally possess poor mechanical properties, a short fatigue life, low chemical resistance, poor long-term durability, and limited processing capability. In order to overcome these deficiencies, biopolymers can be reinforced with fillers or nanofillers (with at least one of their dimensions in the nanometer range). Bionanocomposites are advantageous for a wide range of applications, such as in medicine, pharmaceutics, cosmetics, food packaging, agriculture, forestry, electronics, transport, construction, and many more.
