Children of God for Life discovered Pepsi's partnership with Senomyx in developing flavor enhancers for its products. The latter uses cells from the line HEK - which stands for "human embryonic kidney". This line was derived from an aborted baby.
As you read the COG site for information, you'll notice that Pepsi's responses have been dismissive and perhaps even flippant. This is unacceptable. I heard of this about a month ago. Until then I had been drinking Pepsi almost exclusively. No more.
