This was a big one for celebrity trainers Jeanette Jenkins, Jackie Warner, and Valerie Waters. Valerie, who has worked with Jessica Biel, sticks to the mantra, "If a food item has ingredients you don't recognize or can't pronounce, you probably shouldn't eat it." Jackie says that "everyone has to understand that bread, crackers, croutons, things like that, that's sugar. As soon as it's in your system, it processes straight to sugar then straight to fat." Jeanette Jenkins, trainer to Kelly Rowland, steers clear of processed foods, because they "create inflammation in the body and increase the risk of disease."
