Our native immune system is truly amazing in its complexity and ability to continually adapt to an ever changing environment of potential pathogens that could easily colonize and highjack our health if not detected and eradicated quickly. Many people, especially as they age, have a compromised immune response due to negative lifestyle factors including smoking, exposure to environmental and household toxins, stress and especially diet. Up to 80 percent of our initial immune response takes place in our digestive system, and the body uses cues from what we eat to activate essential actions to potential invaders.
Consuming a largely processed food diet that is void of nutrients and flavonoids dulls our immune system and dramatically increases the risk of infection, inflammation and chronic disease. A research team from the Walter and Eliza Hall Institute’s Molecular Immunology Division in Australia have published the result of their work in the journal Nature Immunology that demonstrates how eating your greens may be even more important than previously thought, with the discovery that an immune cell population essential for intestinal health could be controlled by leafy greens in your diet.
Leafy greens and crucifers help express digestive genes that boost our innate immune response
A special type of immune cell known as an innate lymphoid cell (ILC) is found throughout the digestive tract and can help protect the body from invading pathogens and also provides a balance between ‘good’ and ‘bad’ bacteria in the intestine. Additionally ILC’s play an important role in controlling food allergies, inflammatory diseases and obesity, and may even prevent the development of bowel cancers. The team discovered that a gene (T-bet) is responsible for producing these critical immune cells and is expressed by signals fed from the foods we eat.
