As we age, numerous aspects of our body begin to deteriorate, including our mental as well as physical capacities. One area that is not given as much thought but is a fact of aging is the gradual decline of our immune systems, a process known as immunosenescence. While keeping our mind and body active can go long way to maintaining their good standing, proper nutrition is important for optimal immune health. This would include the usual dietary suspects, including fresh fruits and vegetables, lean meats, legumes, and whole grains.

Now researchers are beginning to see that cheese can help enhance our immunity, as well. The reason for this is because cheese contains probiotic bacteria, which have been shown to have numerous health benefits, and daily consumption of cheese helps to temper immunosenescence, which can result in the body's inability to destroy tumor cells and respond to vaccinations and infections. In fact, infectious disease, chronic inflammation, and cancer are often associated with immunosenescence.

The data, published in the journal FEMS Immunology & Medical Microbiology, are particularly relevant in light of the growing number of people who are approaching or have reached senior status. Previous studies have supported probiotic bacteria's role in aiding immunity, but this is the first time that cheese has been cited as a source for them.

In order to arrive at their findings, scientists looked at volunteers between the ages of 72 and 103 years of age. They were asked to consume either probiotic cheese (Gouda) or a placebo with their breakfast over the course of 4 weeks. Blood tests were administered for the effect, if any, that the probiotic bacteria had on immunity. The gastrointestinal (GI) tract was the focus of the inquiry because that is the primary entry point into the body for probiotic bacteria, and it is where a majority of the immunoglobulin cells are produced.

What they found was that there was clearly an enhancing effect, as evident by an observed activation of certain blood cells as well as an increase in phagocytic activity. The authors concluded that including probiotic cheese may be an effective way to support the immune system and help prevent its inevitable decline with age. Further studies, however, need to be done before any definite conclusions about cheese and immunity can be made.

With this is mind, it is important to note that the study is not a declaration to go out and eat more cheese, though with proper planning, it can be part of a wholesome and nutritious diet. If you have questions or concerns about immunosenescence, speak with your doctor.
