Over the past few years, the beverage industry has exploded with so‑called “health drinks.” From probiotic sodas to wellness tonics, these products are often marketed as gut-healing, metabolism-boosting, or blood-sugar friendly alternatives to traditional soda.

While the marketing is convincing, I’m often asked in practice whether these drinks are actually healthy. My answer is usually: not as much as they’re made out to be.

When it comes to nutrition, fiber rarely gets the spotlight it deserves. Yet fiber plays a foundational role in digestive health, cardiovascular health, blood sugar regulation, hormone balance, and even immune function. Most adults fall significantly short of daily fiber needs—and this gap alone can contribute to many of the chronic health concerns I see in practice.
