SECOND VIOLATION:
OXIDATION ON THE
INSIDE
One of fat’s jobs is to help build and
maintain our cell membranes. This means that
the type of fat we eat is reflected in the
makeup of our cell walls. If we eat too many
PUFAs, some will probably have oxidized in
the bottle (and our frying pan), leading to
toxic byproducts when ingested. The rest—
which hasn’t oxidized—is then built into our
cell walls. But just as seed oils are the least
stable on the shelf and in the frying pan, they
are also the least stable in the body.
Polyunsaturated fat is the most likely type
of fat to oxidize inside our bodies.When we eat too much PUFA-rich seed
oil, it makes up a larger and larger proportion
of our cell membranes, which in turn makes
