Glycemic
Index
Not all foods
affect blood glucose levels in the same way. Some foods have what
is called a high glycemic index, which means that they
can raise blood glucose levels rapidly.
Eating a lot
of high glycemic index foods forces the body to produce insulin
in large amounts to try to clear the high levels of glucose in
the blood. Over time, this increase in insulin production can
increase the risk of diabetes.
In the NHS,
we found that women who ate the most foods with a high glycemic
index had a 50% greater risk of diabetes than those who ate the
least.
Examples of
foods with a high glycemic index include baked potatoes and white
bread, while foods with a low glycemic index include apples, beans,
and whole grain pasta.
