On Monday Brady got heated during an interview on Boston sports radio station WEEI about Coca-Cola, calling the sugary beverage "poison."
"The fact that they can sell that, you know, to kids, that's, I mean that's poison for kids, but they keep doing it," Brady said.
Brady, a father to two sons and one daughter, also took a shot at breakfast cereals, specifically the cereal represented in advertisements by the character Tony the Tiger.
"That's just America and that's what we've been conditioned to so, you know, we believe that Frosted Flakes are actually, is a food," he said.
The 38-year-old, four-time Super Bowl champion credited a healthy diet as a big part of his on-field success. He also accused certain large food and beverage companies of false advertising.
"All those companies make lots of money selling those things," Brady told WEEI. "They have lots of money to advertise, you know? When you go to the Super Bowl, it's you know, that's who are the sponsors. That's the education that we get. That's what we get brainwashed to believe."
The Coca-Cola Co. responded to Brady's comments by calling itself a "responsible beverage company and marketer."
“All of our beverages are safe and can be enjoyed as part of a balanced lifestyle," Coca-Cola Co. told ABC News in a statement. "We offer more than 200 low- and no-calorie beverages in the U.S. and Canada and a wide variety of smaller portion sizes of our regular drinks. As a responsible beverage company and marketer, we prominently provide calorie and sugar information for our beverages so people can choose what makes sense for them and their families.”
Kellogg Company spokesperson Kris Charles responded to Brady's comments by saying Frosted Flakes delivers "valuable nutrients."
"Cereal is a delicious and nutritious breakfast," Charles told ABC News. "Numerous studies show that a cereal breakfast is associated with lower BMIs in both children and adults. As a matter of fact, a serving of Frosted Flakes with skim milk has just 150 calories and delivers valuable nutrients including calcium, B vitamins and iron."
"She's my best friend so we get to do everything together and, especially when you're fortunate enough to be in a relationship with someone you love to death, you love doing anything with them," Brady told Yahoo Style.
