What should elderly people with low immunity eat?

In general, low immunity in the elderly can be improved by adjusting diet and lifestyle habits to enhance immune function and overall health. First, it is important to consume more vegetables and fruits rich in protein, vitamin B complex, and vitamin C, such as kiwifruit, celery, apples, and oranges. Second, include foods high in vitamin E and zinc, such as legumes and gourds, to support immune system development. Additionally, older adults may benefit from eating nourishing foods like oats, red dates, brown rice porridge, chestnuts, and infant cereal to increase nutritional intake. Regular physical activity is also recommended for seniors to strengthen their constitution and boost immunity. Furthermore, adequate rest, avoiding late nights, and maintaining a positive mood are essential to promote healthy immune system function.
