According to Leatherhead Food RA, Surrey, U.K., the global market for functional food is over $30 billion and estimates that it will eventually reach 5% of total world food expenditures in developed countries. LFRA defines the functional food market as a variety of healthy products not necessarily making health claims, but often perceived as functional foods.
Market researcher Frost & Sullivan reports the U.S. functional beverage market generated revenues of $4.7 billion in 2000, and expects this figure to top $12 billion by 2007.
