    Editorial: from preconception to senescence: how do food and dietary interventions modulate health, immunity, and stress?
    (Frontiers In Nutrition, 2024-02) Maia, Juliana Kelly da Silva; Aquino, Jailane de Souza; Guzmán-Quevedo, Omar
    Recent discussions pointed to the profound impact of food and dietary interventions on various facets of wellbeing, including immune function and stress management. The rising interest in different dietary patterns, diet interventions, like intermittent fasting, and the introduction of bioactive compounds in diets has continuously increased due to their potential for health maintenance, as well as prevention and treatment of diseases (1), in addition to immunomodulatory and anti-stress properties (2, 3). These dietary interventions can contribute to health promotion from the preconception, the earliest life phases, until senescence. However, some dietary interventions can negatively affect different stages of life (1, 4). For this reason, this Research Topic aimed to publish articles that address the repercussions of dietary interventions including intermittent fasting, specific diets, and bioactive compounds on the modulation of health, immunity, and stress through the cycle of life. In this Research Topic, four articles were published, covering the aforementioned aspects. Dietary restriction may imply weight loss and reduced systemic inflammation associated with obesity. An emerging strategy to decrease caloric intake is intermittent fasting. Regarding this, Mulas et al. conducted a review to assess how the two main forms of intermittent fasting (i.e., time-restricted eating and alternate-day fasting) impact body weight and key circulating inflammatory markers in adults with obesity. Results from this review indicate that time-restricted eating with various eating window durations (4–10 h per day) does not affect circulating levels of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-alpha), and interleukin-6 (IL-6); even with a weight loss of 1–5%. Regarding alternate-day fasting, reductions in CRP concentrations were observed when >6% weight loss was achieved. However, this did not affect TNF-alpha or IL-6 concentrations at this degree of weight loss. Thus, intermittent fasting has little or no effect on key inflammatory markers, but further research is needed to confirm these preliminary findings
