Core Viewpoint - Traumatic brain injury (TBI) not only manifests as physical trauma but can also lead to various physiological and psychological changes that affect the quality of life and daily functioning of patients. Nutritional support is crucial during the rehabilitation process, as specific nutrients can accelerate nerve repair, enhance immunity, and promote brain function recovery [1]. Group 1: Importance of Specific Nutrients in TBI Recovery - The recovery period after TBI involves physical recovery, brain function repair, and emotional regulation, requiring significant energy and nutritional support [2]. - Specific nutrients such as omega-3 fatty acids, B vitamins, and antioxidants can accelerate nerve cell repair and regeneration, reduce inflammation, and provide essential materials for neuronal recovery [2]. - Nutrients like vitamin C, vitamin E, zinc, and selenium can enhance immune system function, helping to resist infections and maintain physical strength during recovery [2]. - Anti-inflammatory nutrients, including omega-3 fatty acids and vitamins D and C, are essential for controlling inflammation, which is a key mechanism in nerve damage [2][3]. Group 2: Foods that Promote Nerve Repair - Foods rich in omega-3 fatty acids, such as deep-sea fish (e.g., salmon, tuna), flaxseeds, chia seeds, and walnuts, are crucial for brain health and can help reduce inflammation [4][5][6]. - Foods high in B vitamins, including whole grains, lean meats, and dairy products, are vital for promoting nerve function and repairing damaged nerve cells [6][7][8]. - Antioxidant-rich foods like blueberries, dark green vegetables, and nuts can help mitigate oxidative stress and protect nerve cells [8][9][10]. - Foods containing magnesium, such as leafy greens, legumes, and whole grains, are important for normal nerve function and can alleviate anxiety and sleep disorders [10][11][12]. - Zinc-rich foods, including red meat, shellfish, and seeds, play a critical role in cell repair and immune function [11][12][13]. - High-quality protein sources, such as fish, poultry, tofu, and dairy, are essential for cell repair and regeneration during the recovery phase [13][14][15]. Conclusion - The rehabilitation period after TBI is complex and lengthy, requiring scientific treatment, appropriate rehabilitation training, and sufficient nutritional support. Supplementing specific nutrients can effectively promote nerve repair, reduce inflammation, enhance immunity, and accelerate brain function recovery. A balanced diet not only aids brain recovery but also improves overall health, making nutritional attention vital for patients and their families during the recovery journey [15].
