7 Super Foods That Help Fight A Cold

One of the most common infections in the world is the common cold. Colds are respiratory infections that are caused by more than 200 possible viruses. Often, a weak immune system that allows the virus to attack the body causes the common cold. In the US alone, the direct medical costs related to the common cold were a whopping $17 billion a year in 1997.1

The severity and the symptoms differ among individuals and with different infective agents. Children under two years have about six infections a year, adults two to three and older people about one per year.2 Certain foods not only help prevent the cold but also have a curative effect and can help accelerate the recovery. Here are seven such superfoods.

Turmeric belongs to the ginger root family and is native to southwest India. Its effect in treating cold is attributed to one of its components called curcumin.3 Like garlic, curcumin has the power to activate white blood cells whenever an infection threatens the body. Turmeric is popular for its multifunctional properties, including antibacterial activity.4 Even at low doses, curcumin is effective in inhibiting the growth of bacteria. By staving off the infection-causing bacteria, the immune system kicks in and protects you from a cold.

For ages, garlic has been used for its health-related properties. It is an effective cure for the common cold and can help boost the immune system. It has antibacterial, antioxidant, antiviral, and antiseptic properties and is widely used in traditional medicine preparation in many countries. Studies from the Journal of Immunology Research shows that garlic can enhance the immune system by helping maintain balance in your body’s cells.5

It plays a crucial role in stimulating the production of two types of white blood cells called macrophages and lymphocytes, which attack the infection-causing germs. Garlic also stimulates the secretion of a protein called cytokine, which sends a signal to the macrophages to attack cellular waste, harmful bacteria, and anything that is detrimental to your health.

Citrus fruits are loaded with vitamin C that fights the cell-damaging free radicals and is crucial for a strong immune system. A natural chemical called limonene found in citrus fruit peels could play a potential role in the treatment of bronchitis. Studies have shown that vitamin C can successfully treat and/or prevent the common cold.

The intake of vitamin C may reduce the duration of the common cold and ameliorate symptom severity due to the antihistamine effect of high-dose vitamin C. While regular consumption of vitamin C can keep the common cold at bay, consuming it after the onset of cold symptoms is comparatively less beneficial.12 13
