Which is a benefit of a high fiber diet?

• A. Increases blood pressure
• B. Normal bowel movements, lowers cholesterol, controls blood sugar, aids in achieving healthy weight.
• C. Causes dehydration
• D. Promotes muscle growth

Answer: (B)

High-fiber intake supports digestion, heart health, metabolic control, and weight management. It promotes normal bowel movements by adding bulk and moisture to stool, which helps prevent constipation. Soluble fiber binds cholesterol in the gut, increasing its excretion and lowering LDL cholesterol. It also slows the absorption of sugar, helping to stabilize post-meal blood glucose and improve insulin sensitivity. Additionally, fiber-rich foods tend to be more filling and lower in calories, aiding in achieving a healthy weight. These combined effects illustrate why a high-fiber diet offers multiple benefits. Dehydration is not a benefit and can occur if fluid intake is insufficient, while fiber does not promote muscle growth—that role comes from adequate protein and resistance training.
