What foods can boost immunity?

To enhance immunity, it is essential to start with improving nutritional status by maintaining a complete and balanced diet, emphasizing foods rich in vitamins and trace elements. 1. Vegetable oils: Vegetable oils provide various types of polyunsaturated fatty acids (PUFAs), which support good immune function and help regulate the immune system, thereby improving immunity. Common vegetable oils include rapeseed oil, soybean oil, and olive oil. 2. Vegetables: Polyphenols, vitamin A, vitamin C, and vitamin E found in vegetables can all help regulate the immune system and promote enhanced immunity. High-quality vegetable choices include spinach, carrots, broccoli, asparagus, celery, and cabbage. 3. Whole grains: Dietary fiber in whole grains effectively helps improve the structure of gut microbiota and enhances gastrointestinal health, thereby boosting immune system function. It is recommended to consume whole grain products such as whole wheat bread, oatmeal, and brown rice daily. 4. Legumes: Legume-based foods are rich in protein and dietary fiber, and also provide various vitamins and trace elements, contributing to improved immunity. Common legumes include tofu, soybeans, peas, and mung beans. 5. Fruits: Fruits are rich in vitamin C, which helps maintain normal immune system function and strengthens immunity. It is advisable to eat fresh fruits daily, such as oranges, grapes, and tangerines.
