What Should Elderly People Eat to Boost Their Immunity?

As people age, their immune function naturally declines, rendering them more susceptible to illness. Therefore, it is important for older adults to consume foods that help bolster immunity. So, what foods are beneficial for enhancing immunity in the elderly?

What Foods and Supplements Help Boost Immunity in Older Adults?

Dietary choices and certain herbal medicines can effectively support immune function in older adults. Immune deficiency in the elderly is often attributed to deficiencies in kidney essence, qi (vital energy), or blood, and may be addressed with tonifying herbs that nourish qi and blood. Examples include Cordyceps sinensis (Caterpillar fungus), Scutellaria baicalensis (Baikal skullcap), Astragalus membranaceus (Huang Qi), Angelica sinensis (Dang Gui), Codonopsis pilosula (Dang Shen), Panax ginseng (Ren Shen), velvet antler (Lu Rong), and donkey-hide gelatin (E Jiao). When immune decline stems from blood deficiency, herbs such as Salvia miltiorrhiza (Dan Shen), Carthamus tinctorius (Hong Hua), and Rhodiola rosea (Hong Jing Tian) may be used. Additionally, oral administration of thymic peptide lyophilized powder or intramuscular injection of thymopentin may help restore immune function.

Certain foods and supplements can also enhance immunity in older adults. These include Chinese yam, tomatoes, potatoes, mustard greens, grapes, apples, and kiwifruit—fresh fruits and vegetables rich in vitamins and trace elements that support immune health and contribute to disease prevention.

Protein-rich foods—including dairy products, eggs, and protein powders—also aid immune enhancement. Moreover, adequate protein intake helps maintain muscle strength, thereby reducing the risk of falls and fractures. Other beneficial immune-supportive supplements include honey, bird’s nest, Cordyceps sinensis, and ginseng. We hope this article has been helpful. Wishing you a joyful life and optimal health!
