Fiber Frenzy: Experts Unveil the Holistic Health Benefits of High-Fiber Diets

According to the article, fiber is a crucial component of a healthy diet, providing benefits that extend far beyond just digestion. As the "fibermaxxing" trend gains traction, nutritionists are highlighting the importance of understanding the various types of fiber and their distinct impacts on the body.

Longevity expert Dr. Peter Attia explains that people who consume a high-fiber diet tend to engage in other healthy behaviors, such as exercising more, smoking less, and getting better sleep. This makes it challenging to isolate the specific effects of fiber, as it is often part of a broader healthy lifestyle.

Attia delves into the differences between soluble and insoluble fiber, noting that each type plays a unique role in the body. Soluble fiber can help regulate blood sugar and potentially lower cholesterol, while insoluble fiber adds bulk to stool, reducing constipation and supporting regular bowel movements.
