white bread (with a score of 70 to
73).White bread raises blood sugar very
rapidly (high GI), while the starch in 100
percent whole-grain bread takes longer to
break down into glucose (moderate GI). The
lower GI score is largely a result of the
additional fiber content of whole-grain flour,
but eating a high GI food alongside other
foods rich in fiber and fat will also lower the
total GI of the meal.
However, the GI does not give any
indication of, well, anything else relating to
the health of these foods! It doesn’t mention
whether the food contains any problematic
proteins, or what kind of sugars or fats it
contains, or the bioavailability of the
nutrients. It also doesn’t tell you how much
carbohydrate is contained in the food or how
much insulin will be needed to manage blood
