Dr. Liu Aihua
There is a close relationship between boosting the body's immune system and our diet. To achieve strong immunity, nutrition is the most fundamental and important factor. Generally speaking, to enhance immunity, one should consume more foods rich in nutrients, such as vegetables, fruits, legumes, and whole grains. These natural sources of nutrition provide essential vitamins, minerals, and proteins, and also help prevent diseases, reduce inflammation, and lower blood lipid levels, thereby supporting improved immune function. In addition, it is recommended to eat more foods with antioxidant properties, such as vegetables, fruits, fish, whole grains, pistachios, and sesame seeds. These are rich in antioxidants that can strengthen the body’s antioxidant capacity, reduce oxidative damage, and thus boost immunity. Furthermore, regulating one’s emotional state can also help improve immunity. Research shows that depression and anxiety can weaken the immune system, making individuals more susceptible to illness. Therefore, in daily life, it is advisable to participate in enjoyable activities and maintain a positive mood, which contributes to enhanced immune function.
