Nutritional strategies for autophagy activation and health consequences of autophagy impairment.
Currently, the plague of chronic diseases, such as overweight, obesity, diabetes, and cardiovascular diseases, is associated with chronic inflammation as an effect of homeostasis disbalance. One of the processes involved in homeostasis maintenance is autophagy, which is also referred to as self-eating or cellular recycling. Due to the correlation between the epidemic scale of chronic diseases and autophagy impairment, strategies for autophagy activation are urgently needed. ⋯ Autophagy is involved in different dysfunctions and diseases; thus, activation strategies are urgently needed. A high potential in the prevention and therapies of chronic diseases by means of autophagy induction can be expected from nutritional behaviors. To date, most studies were carried out in vitro or in a murine model. Thus, further, well-designed, clinical trials are needed to provide the missing understanding of the nutritional potential to regulate specific signaling pathways that keep autophagy running smoothly.

Individuals with cancer may be motivated to make lifestyle changes and informed dietary choices, but are exposed to conflicting and erroneous nutrition information, particularly from online and social media sources. Changes to dietary choices that stem from a diagnosis of cancer are not fully understood. Thus, we conducted a narrative review to summarize the literature focused on dietary choices after a cancer diagnosis, and highlighted influential factors. ⋯ These changes align with the recommendations for cancer prevention but were implemented after diagnosis, and may not meet nutrition guidelines for patients with cancer. Age and time since diagnosis were among the influential factors that affected these postdiagnosis changes. Data on dietary changes implemented after a diagnosis of varying cancer types in the North American population are lacking, and would provide practitioners with an enhanced understanding of patient information needs and reasons for dietary choices.

Numerous smartphone-based applications that guide parenting, child nutrition, and child health-related knowledge are available. Here, we reviewed the applications available in the Google Play Store for child nutrition, primarily focused on children aged <5 y. The keywords used in the search were "child nutrition," "child nutrition status assessment," and "parenting." We identified 370 apps from the play store and 33 qualified for the review. ⋯ Findings from this review suggest that the apps do not follow any uniform guidelines for delivering the child nutrition information to the caregivers. About 50% of apps did not mention the consulted source for its development, indicating the unavailability of uniform guidelines or policy documents for child nutrition app development. App-based intervention studies are recommended to assess the effectiveness of child nutrition/health smartphone applications.

The potential clinical effects of licorice (Glycyrrhiza spp.) and its extracts have been investigated since ancient times. Whether pseudohyperaldosteronism, with consequent arterial hypertension, is the only endocrine effect produced by licorice is uncertain, and a role in the reproductive system has been proposed. This review aimed to summarize the current knowledge on the pharmacologic effects of licorice on male and female reproductive systems. ⋯ Licorice consumption can affect the reproductive system. However, its role needs to be further explored, especially due to the great variability of bioactive compounds used in existing studies.

Gastrointestinal tract diseases are characterized by an imbalance in physiological functions, which may involve inflammatory and metabolic pathways and trigger chronic, multifactorial, and idiopathic inflammatory disorders. The association of probiotics with prebiotics has the potential to remedy these afflictive conditions, because they attenuate or even block the adhesion of pathogenic microorganisms in the enteric environment. ⋯ The importance of products containing probiotics and fibers from Psyllium as prebiotics becomes increasingly evident when there is a health bias. Emerging health challenges and advances in research will drive selective approaches in biotechnology to discover and evaluate new probiotics and prebiotics that can potentially contribute to human health.
