Rice Fiber

Rice Fiber is a pure, natural extract from the outer bran layer of the rice grain. Unlike white rice, which is stripped of nutrients, rice fiber concentrates the digestive and heart-protective elements of the grain. It is a powerhouse of insoluble fiber, acting as a natural regulator for your gut health. It helps bulk up stool for easier passage and can assist in managing cholesterol levels naturally.

Health Benefits & Sources

Why You Need It

  • Digestive Regularity: Acts as a natural 'broom' to sweep the colon.
  • Satiety: Expands in the stomach to curb appetite.
  • Cholesterol Control: Contains oryzanol to help lower LDL.
  • Gut Health: Feeds beneficial bacteria.

Deep Dive

Rice fiber is unique because it is almost entirely insoluble fiber. While soluble fiber dissolves in water to form a gel, insoluble fiber does not. This makes it particularly effective for those struggling with slow transit time (constipation). It physically pushes waste through your system. Additionally, the presence of plant sterols in rice bran makes it a functional food for heart health, offering benefits beyond simple digestion.

Natural Food Sources

To get rice fiber naturally, choose whole grain rice varieties. The white rice you see on most tables has had the fiber-rich bran layer removed.

Supplementation

Rice fiber supplements are best used as a daily 'top-up' if your diet lacks whole grains. It is a flavorless white powder that dissolves easily. It is a great alternative to psyllium husk for those who dislike the texture of gel-forming fibers.
