Avoid foods with the preservatives ethoxyquin, butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), which are highly toxic.
Preservatives range from safe, natural substances such as tocopherol (vitamin E) and ascorbic acid (vitamin C) to highly toxic chemicals such as ethoxyquin, butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA).
For example, tertiary butylhydroquinone (TBHQ), butylated hydroxyanisole (BHA), and butylated hydroxytoluene (BHT) show evidence of carcinogenic activity in animal trials.
