Introduction
In general, to enhance resistance and immunity, one can consume foods such as blueberries, eggs, broccoli, salmon, and kiwifruit. Additionally, under medical guidance, medications such as pidotimod oral solution, splenocyte peptide oral lyophilized powder, transfer factor oral solution, Yupingfeng granules, and Astragalus granules may be taken for immune regulation. A detailed analysis is as follows:

Additionally, under medical guidance, medications like pidotimod oral solution, spleen aminopeptide oral lyophilized powder, transfer factor oral solution, Yupingfeng Granules, and Astragalus Granules may be taken for immune regulation. Specific details are as follows:

I. Foods

1. Blueberries
Rich in anthocyanins and vitamin C, anthocyanins have strong antioxidant properties that protect immune cells from oxidative damage. Vitamin C promotes lymphocyte production and enhances immune cell activity, helping the body resist external pathogens. Blueberries can be eaten directly or paired with yogurt.

2. Eggs
Contain high-quality protein, lecithin, and vitamin D. Protein is an essential component for synthesizing immunoglobulins and helps strengthen immune cell function. Lecithin maintains the normal structure of immune organs, while vitamin D regulates immune responses. Consuming eggs in moderation daily provides foundational nutrition for the immune system.

3. Broccoli
Rich in vitamin C, vitamin K, and dietary fiber. Vitamin C enhances the phagocytic ability of white blood cells; vitamin K helps maintain metabolic balance in immune cells; dietary fiber regulates gut microbiota, indirectly boosting immunity by improving intestinal health. It is best consumed after blanching, either stir-fried lightly or served cold.

4. Salmon
High in omega-3 unsaturated fatty acids and vitamin D. Omega-3 helps reduce systemic inflammation, preventing excessive inflammatory responses from damaging the immune system. Vitamin D activates immune cells and improves the body’s ability to recognize pathogens. Suitable cooking methods include steaming or baking.

5. Kiwifruit
Extremely rich in vitamin C, and also contains actinidin and dietary fiber. Vitamin C promotes immunoglobulin synthesis and enhances antibody activity. Actinidin stimulates immune cell proliferation, while dietary fiber improves the intestinal environment, helping maintain immune homeostasis. Best eaten raw.

II. Medications

1. Pidotimod Oral Solution
An immunostimulatory regulator that activates macrophages and T-lymphocytes, promotes secretion of immune factors, and enhances the body's resistance to bacteria and viruses. Suitable for individuals with low immunity, especially those prone to recurrent respiratory infections.

2. Spleen Aminopeptide Oral Lyophilized Powder
Extracted from animal spleens, it contains polypeptides and nucleotides that directly supplement immune-active substances, promote lymphocyte proliferation and differentiation, and rapidly improve cellular immune function. Recommended for individuals with impaired or deficient immune function. Requires refrigerated storage.

3. Transfer Factor Oral Solution
Contains polynucleotides and polypeptides that transfer immune information from donor to recipient, activating the recipient’s immune system and enhancing the recognition and clearance of pathogens. Suitable for individuals with recurrent infections or immune system disorders.

4. Yupingfeng Granules
Composed of Astragalus, Atractylodes, and Saposhnikovia, this formula tonifies qi, strengthens the exterior, and stops sweating. By enhancing the body's defensive qi, it reduces invasion by external pathogens. Suitable for individuals with qi deficiency who are prone to colds.

5. Astragalus Granules
Primarily composed of Astragalus, it functions to tonify qi, elevate yang, consolidate the exterior, and stop sweating. Astragalus polysaccharides in the herb promote immune cell proliferation, enhance macrophage phagocytosis, and improve overall immune function. Suitable for individuals with qi deficiency, fatigue, and low immunity.

In daily life, it is also important to maintain healthy habits, ensure adequate sleep, avoid excessive fatigue, and engage in moderate physical exercise. When necessary, seek timely medical evaluation to identify the cause of low immunity and use medications under professional medical supervision.
