This article Food Production and Animal Testing (see
http://www.aboutanimaltesting.co.uk/food-production-animal-testing.html ) supports your theory , " the use of animal testing for foods, food additives, nutritional supplements and sweeteners tripled from 2005 to 2006."
"The trend in recent years to eat healthier foods has led to a massive demand and surge in the marketplace for such products. Ironically, this has led to a similar increase in the number of laboratory animals used for testing of food products, which includes additives and various health formulations. Claims that a specific margarine can aid in cholesterol reduction or that a yogurt can help to improve digestion all require animal testing and then clinical trails to show the validity of the claims prior to their approval."
"As more people become concerned with health and nutrition, the demand for easier improvement of health through nutritionally enhanced foods will likely continue, which unfortunately for animals means that their use will become more important than ever."
