Blueberries can boost immune system

The immune system consists of organs, cells, tissues, and proteins. Together, these carry out bodily processes that fight off pathogens, which are the viruses, bacteria, and foreign bodies that cause infection or disease. Some foods, especially fruit berries provide plenty of antioxidants with their specific biochemical functions, and are beneficial to health.

Scientists think these antioxidants may help protect you from cancer, heart disease, and dementia, and boost your immune system.

Blueberries contain flavonoids called anthocyanin — a type of antioxidant that can help reduce damage to cells and boost human immune system.

One of the means through which anthocyanins are thought to inhibit tumor formation is linked with their potential immunomodulatory effects, possibly through the stimulation of natural killer cells (NKC; a group of lymphocytes responsible for the immune response to abnormal cells).

Study shows that people who ate foods rich in flavonoids were less likely to get an upper respiratory tract infection, or common cold, than those who did not.
