• After our friends child
exhibited reactions to foods
and drinks containing RED DYE
40 and as a result of doing some
checking, asking questions, and
a few hours of research, we
found this happens to many
children and adults too! We felt
the need to do more research
and provide information that
may help others deal with
reactions to RED DYE 40 as well
as other chemical additives in
our foods. We are NOT doctors
just concerned parents like you.

• Dr. John Swartzberg at the UC
Berkeley Wellness Letter says
cochineal extract, also known as
carmine, is in all sorts of things,
including "fruit drinks, yogurts,
ice creams, fruit filling, lots of
other foods, cosmetics, like
lipsticks and a lot of drugs."
This bug dye doesn't sound very
yummy, but it's considered safe
by the Food and Drug
Administration, except for a
small group of people who have an
allergic reaction to it. The
Wellness Letter says in rare
cases that reaction could be lifethreatening.
