Intermittent fasting regimens have emerged as a dietary tool to improve the glycemic profile, but a critical appraisal of clinical studies assessing the effects of IF regimens in patients with diabetes is needed. Join us for this episode where Douglas Taren speaks with Heitor Santos, author of this episode's featured article, a review of glycemic control and safety of intermittent fasting for the management of diabetes.

Vitamin  D plays an important role in immune function, and the deficiency thereof has been associated with several infections, most notably respiratory tract infections. However, data from intervention studies investigating the effect of high-dose vitamin D supplementation on infections have been inconclusive. Join us for this episode where Douglas Taren speaks with Janet Carboo and Martani Lombard Centre of Excellence for Nutrition (CEN), North-West University, Potchefstroom, North West Province, South Africa, about their systematic review and meta-analysis on high-dose oral vitamin D supplementation for prevention of infections in children.

Nonalcoholic fatty liver disease (NAFLD) is prevalent in 25–30% of British and European populations, representing a potential global public health crisis. Marine omega-3 (n-3) polyunsaturated fatty acids offer well-evidenced benefits to NAFLD biomarkers; however, the effect of plant-based n-3 has not been evaluated with a systematic review and meta-analysis. Join us for this episode where Douglas Taren speaks with Katie Lane, co-author of this featured article, a review aimed to systematically evaluate the effect of plant-based n-3 supplementation on NAFLD surrogate biomarkers and parameters.

Food labelling is a global strategy recommended to reduce noncommunicable diseases. Few reviews, however, have focused on food label use in sub-Saharan Africa. In this episode, lead author Dumisani Nkhoma from the Nkhata Bay District Hospital, Nkhata Bay District Health Office, Malawi, discusses with Douglas Taren the finding of his systemic review and meta-analysis of food label use and comprehension in sub-Saharan Africa.

Telehealth-delivered nutrition interventions are effective in practice; however, limited evidence exists regarding their cost-effectiveness. In this episode, lead author Jaimon Kelly from the Centre for Online Health, Faculty of Medicine, The University of Queensland, Brisbane, Queensland, Australia, discusses with Douglas Taren his evaluation of twelve randomized controlled trials on the cost-effectiveness of telehealth-delivered nutrition interventions for improving health outcomes in adults with chronic disease.

Intermittent energy restriction (IER) and periodic fasting (PF) has become a popular dietary trend and topic of research for metabolic outcomes and weight loss. This episode, editor-in-chief Dr. Douglas Taren speaks with featured article authors Elske van den Burg and Marjolein Schoonakker on their systematic review summarizing current knowledge of the effects of IER and PF in patients with T2D on markers of metabolic control and the need for glucose-lowering medication.

Retirement is an opportune time for people to establish new healthy routines. Exercise and nutritional interventions are promising in the prevention and treatment of sarcopenic obesity. The authors of this featured article conducted a systematic review and meta-analysis to assess the effectiveness of nutritional and exercise interventions for the treatment of sarcopenic obesity in persons of retirement age. Join us this episode as editor-in-chief Dr. Douglas Taren speaks with Doris Eglseer and Lea Reiter from Institute of Nursing Science, Medical University of Graz, about their thoughts on their findings.

Middle childhood and early adolescence have received disproportionately low levels of scientific attention relative to other life stages, especially as related to nutrition and health. Nevertheless, this age bracket, which encompasses most of the primary education and basic schooling years for most individuals, is marked by significant changes, inflection points, and sexually driven divergence in somatic and brain growth and development trajectories. Join us for this episode where Douglas Taren speaks with Jose Saavedra, co-author of this featured article, on their review highlighting the specificities of growth and development in middle childhood and early adolescence, the role of nutrition, the short- and long-term consequences of inadequate nutrition, and the current global status of nutrition in this age group.
