Several members of our support group
are skeptical of this article and have told me that they don't
believe much of this. They do admit that some people are susceptible
to the inflammation more than others.
When we eat, we do not just take in
nutrients - we also consume a significant quantity of bacteria. The
body is faced with the challenge of simultaneously distributing the
ingested glucose and fighting these bacteria. This triggers an
inflammatory response that activates the immune systems of healthy
individuals and has a protective effect, as doctors from the
University and the University Hospital Basel have proven for the
first time. In overweight individuals, however, this inflammatory
response fails so dramatically that it can lead to diabetes.
It is well known that type 2 diabetes
(or adult-onset diabetes) leads to chronic inflammation with a range
of negative impacts. A number of clinical studies have therefore
treated diabetes by impeding the over-production of a substance
involved in this process, Interleukin-1beta (IL-1beta). In diabetes
patients, this messenger substance triggers chronic inflammation and
causes insulin-producing beta cells to die off.
This inflammation does have some
positive aspects, however, as was recently reported in the journal Nature Immunology by researchers from the Department of Biomedicine
at the University and the University Hospital Basel. In healthy
individuals, short-term inflammatory responses play an important role
in sugar uptake and the activation of the immune system.
In their work, Professor Marc Donath,
Head of the Department of Endocrinology, Diabetes and Metabolism at
the University Hospital Basel and his research team demonstrate that
the number of macrophages (a type of immune cell) around the
intestines increases during meal times. These so-called "scavenger
cells" produce the messenger substance IL-1beta in varying
amounts, depending on the concentration of glucose in the blood.
This, in turn, stimulates insulin production in pancreatic beta
cells. The insulin then causes the macrophages to increase IL-1beta
production. Insulin and IL-1beta work together to regulate blood
sugar levels, while the messenger substance IL-1beta ensures that the
immune system is supplied with glucose and thus remains active.
According to the researchers, this
mechanism of the metabolism and immune system is dependent on the
bacteria and nutrients that are ingested during meals. With
sufficient nutrients, the immune system is able to adequately combat
foreign bacteria. Conversely, when there is a lack of nutrients, the
few remaining calories must be conserved for important life functions
at the expense of an immune response. This may go some way towards
explaining why infectious diseases occur more frequently in times of
famine.
This last paragraph was where the
members of the support group said this is the reason that we have
Allison monitoring our nutrient intake and have our doctors test for
the vitamins and minerals we might be deficient in per Allison.
