Reinvention is the quiet skill that keeps celebrities and brands in the spotlight, but most professionals avoid it. Here's how to master it.

Pepsi will launch its very own prebiotic soda this year, but are these "healthy sodas" actually healthy? We asked experts.

Poppi, a soda brand that sells sparkling prebiotic drinks, is paying $8.9 million in a legal settlement after being accused of false advertising.

The new drink comes just months after Pepsi purchased Poppi – a prebiotic soda known for its low sugar content and organic “gut-friendly” ingredients such as Apple Cider Vinegar. According to the Texas -based company’s website, Poppi contains 5g of sugar and has 25 calories or less.

Poppi’s “gut healthy” promises are false since the soda “only contains two grams of prebiotic fiber, an amount too low to cause meaningful gut health benefits,” the plaintiffs claimed.
