The consumption of specific nutrients and bioactive chemicals found in food has a significant impact on how well the human body functions in terms of immunity. These bioactive compounds' ability to prevent a variety of ailments has been well studied. Consumption of functional foods is widespread throughout numerous cultural groups. In one way or another, which offer advantages above and beyond the need for basic sustenance. Bioactive components with a variety of immunomodulation qualities, including phytoconstituents, polyunsaturated fatty acids and probiotics, are being used to create novel functional meals. These substances influence immunity by their antiviral, antibacterial and antioxidant qualities in addition to immunomodulation. The scientific community is under pressure to provide a suitable and efficient treatment for the severe acute respiratory syndrome coronavirus-2 pandemic, as there is a deadline of sorts.

This study focuses on postpartum mental health, particularly maternity blues (MB) and postpartum depression (PPD). It aims to assess their prevalence, associated risk factors, symptoms and potential management strategies. MB, affecting a substantial number of new mothers, typically resolves within weeks, while PPD, a more severe condition, persists longer but affects a smaller percentage. Identifying PPD remains challenging, with only half displaying clear signs. Clinical tools like the Edinburgh Postnatal Depression Scale aid in assessment, but open communication and support are crucial for affected mothers. Recent findings show a link between prior PPD and heightened susceptibility to depression in subsequent years. PPD is associated with long-term health issues, escalating from 8.5% in the initial eight weeks post-delivery to 18.1% by the first year. Stressful postpartum experiences are prevalent among nearly half of new mothers. Timely intervention is essential for severe postpartum psychiatric conditions. Antidepressants, even during breastfeeding, are considered safe. The study explores diverse contributing factors, including psychological, social, lifestyle and obstetric elements, highlighting the importance of early identification and support for affected mothers.

Antioxidants play a crucial role in mitigating oxidative stress, which is implicated in numerous chronic diseases due to the imbalance between reactive oxygen species (ROS) and the body's ability to neutralize them. This review explores the various mechanisms by which antioxidants protect cells, including scavenging free radicals, chelating metal ions, regenerating other antioxidants, inhibiting oxidative enzymes, repairing oxidative damage and modulating gene expression. Key natural sources of antioxidants include fruits, vegetables, nuts, seeds, whole grains, herbs, spices, tea, coffee and certain animal-based products. The health benefits of antioxidants are substantiated by research highlighting their role in reducing the risk of cardiovascular diseases, cancer, neurodegenerative diseases, eye health issues, diabetes, and supporting immune function. The bioavailability and absorption of different antioxidants vary, influenced by factors such as dietary fat presence and food matrix. Future research directions emphasize understanding synergistic effects, personalized nutrition, the safety and efficacy of supplementation, and novel antioxidant discovery. The review concludes that a balanced diet rich in natural antioxidants is preferable over high-dose supplements for optimal health benefits.
