Editorial: Remodeling Composition and Function of Microbiome by Dietary Strategies - Functional Foods Perspective
Microbes inhabiting the human gastrointestinal tract have been under the spotlight during the last
decade, given the multiple associations detected between specific microbiota profiles and health
status. Diet is widely recognized as the primary environmental variable shaping the intestinal
microbiota in humans. Therefore, the study of diet-microbiota-host interactions deserves special
attention to provide clues to several diseases, including cognitive, metabolic, and immune ones. In
a similar manner, the investigation of the molecular cross-talk between host cells and microbes
in a particular nutritional environment also serves as the foundation for design of innovative
therapeutic strategies based on probiotics, prebiotics, and synbiotics. For instance, a recent
investigation based on resistant starch suggests that discrete dietary fiber structures can be used to
target the production of short-chain fatty acids (1), the major microbiota-derived effector molecules
known to have a wide range of action on host health (2). On the other hand, the gut microbiota has
been disclosed to modulate the effect of dietary fiber on host health, supporting the notion that there
is no one-fits-all diet in the way to seek cost-effective nutritional strategies for health improvement
and weight control (3). Anyhow, consensual benefits for human health in microbiota-targeted
dietary interventions are still perceived, pointing out, for instance, fermented foods as attenuators
of inflammation, and modulators of gut microbiota (4).
The aim of the Frontiers in Nutrition Research Topic (RT) “Remodeling Composition and
Function of Microbiome by Dietary Strategies—Functional Foods Perspective” was to assemble
clinical and pre-clinical studies deciphering the microbiome-driven effects on human health
of innovative functional foods based on probiotics, prebiotics or synbiotics, as well as dietary
supplements. We provide an overview of this RT, including five original research articles and two
review articles

Gut microbiome–micronutrient interaction: The key to controlling the bioavailability of minerals and vitamins?
Micronutrients, namely, vitamins and minerals, are necessary for the proper functioning of the human body, and their deficiencies can have dramatic short- and long-term health consequences. Among the underlying causes, certainly a reduced dietary intake and/or poor absorption in the gastrointestinal tract play a key role in decreasing their bioavailability. Recent evidence from clinical and in vivo studies suggests an increasingly important contribution from the gut microbiome. Commensal microorganisms can in fact regulate the levels of micronutrients, both by intervening in the biosynthetic processes and by modulating their absorption. This short narrative review addresses the pivotal role of the gut microbiome in influencing the bioavailability of vitamins (such as A, B, C, D, E, and K) and minerals (calcium, iron, zinc, magnesium, and phosphorous), as well as the impact of these micronutrients on microbiome composition and functionality. Personalized microbiome-based intervention strategies could therefore constitute an innovative tool to counteract micronutrient deficiencies by modulating the gut microbiome toward an eubiotic configuration capable of satisfying the needs of our organism, while promoting general health
The human microbiomes in pancreatic cancer: Towards evidence-based manipulation strategies?
Recent pieces of evidence have emerged on the relevance of microorganisms in modulating responses to anticancer treatments and reshaping the tumor-immune microenvironment. On the one hand, many studies have addressed the role of the gut microbiota, providing interesting correlative findings with respect to etiopathogenesis and treatment responses. On the other hand, intra-tumoral bacteria are being recognized as intrinsic and essential components of the cancer microenvironment, able to promote a plethora of tumor-related aspects from cancer growth to resistance to chemotherapy. These elements will be probably more and more valuable in the coming years in early diagnosis and risk stratification. Furthermore, microbial-targeted intervention strategies may be used as adjuvants to current therapies to improve therapeutic responses and overall survival. This review focuses on new insights and therapeutic approaches that are dawning against pancreatic cancer: a neoplasm that arises in a central metabolic “hub” interfaced between the gut and the host
