Abstract

Dietary fiber has long been recognized for its role in digestive function. However, currently there is scientific debate about definitions (descriptive and analytical), optimal intake, and essentiality in the human diet. Dietary fiber is a key substrate for bacterial metabolism in the colon, which makes research on dietary fiber an important issue that complements current interest in the gut microbiota. Dietary fiber is also important for prevention and management of cardiovascular disease, diabetes, obesity, and other chronic diseases. This Special Issue will highlight recent research on dietary fiber content in foods and function in human health, ranging from digestive function to chronic disease prevention and management.

Abstract

Studying the origin of life is one of man’s greatest achievements over the last sixty years. The fields of interest encompassed by this quest are multiple and interdisciplinary: chemistry, physics, biology, biochemistry, mathematics, geology but also statistics, atmospheric science, meteorology, oceanography, and astrophysics. Recent scientific discoveries, such as water on Mars and the existence of super-Earths with atmospheres similar to primordial Earth, have pushed researchers to simulate prebiotic conditions in explaining the abiotic formation of molecules essential to life. This collection of articles offers an overview of recent discoveries in the field of prebiotic chemistry of biomolecules, their formation and selection, and the evolution of complex chemical systems.

Abstract

Inequity starts before birth and is programmed in part by nutritional exposures. If these exposures occur around the time of conception, during pregnancy, and/or in infancy or childhood (all critical periods of development) they may alter a child’s health trajectory and impact risk for impaired cognition and learning, and cardiometabolic, immune, and neuropsychiatric diseases and disorders. This Special Issue on “Early Life Nutrition and Future Health” has the following aims: 1) understand the origins of offspring health inequities from an early nutritional perspective; 2) uncover new insights into the environmental, biological, and social mechanisms that underpin these health outcomes in offspring; and 3) present novel targets and approaches to optimise health trajectories and prevent chronic diseases and disorders in later life and across generations. The research projects included herein highlight novel mechanistic, epidemiologic, and intervention studies that target key windows where nutrition has the greatest influence on future health (preconception, prenatal, and postnatal periods) and that explore vulnerable populations and animal models of early life nutritional programming.

Abstract

The goal of this Special Issue, “Probiotics and Prebiotics in Pediatrics”, is to focus on the importance of pediatric nutrition with probiotics and prebiotics to improve gastrointestinal health in newborn, infants, and children.Specifically, the aim is to clarify if probiotics and prebiotics can influence gut microbiota composition and host-interaction favoring human health and preventing diseases.This new information will provide health care professionals with a widespread, clear and update evidence on probiotics and prebiotics and intestinal gut microbiota in pediatric care.

Abstract

In 1978, Fred Hoyle proposed that interstellar comets carrying several viruses landed on Earth as part of the panspermia hypotheses. With respect to life, the origin of homochirality on Earth has been the greatest mystery because life cannot exist without molecular asymmetry. Many scientists have proposed several possible hypotheses to answer this long-standing L-D question. Previously, Martin Gardner raised the question about mirror symmetry and broken mirror symmetry in terms of the homochirality question in his monographs (1964 and 1990). Possible scenarios for the L-D issue can be categorized into (i) Earth and exoterrestrial origins, (ii) by-chance and necessity mechanisms, and (iii) mirror-symmetrical and non-mirror-symmetrical forces as physical and chemical origins. These scenarios should involve further great amplification mechanisms, enabling a pure L- or D-world.
