In 1975, CSPI published a "White Paper on Infant Feeding Practices" aimed at criticizing the commercial baby food industry's products and advertising. The White Paper started a formalized, political discussion of issues surrounding early introduction of solid foods and the extraordinarily processed ingredients in commercial baby food. CSPI took particular issue with the modified starches, excessive sugar and salt additions, and presence of nitrates in baby food products. In addition, the White Paper criticized branding and advertisements on products, which they argued lead mothers to believe that solid foods ought to be introduced earlier in an infant's diet.
