Verified step by step guidance

1. Understand the role of dietary fiber: Fiber is a type of carbohydrate that the body cannot digest. It is found in plant-based foods such as fruits, vegetables, whole grains, and legumes. Fiber is classified into two types: soluble and insoluble, each with distinct health benefits.
2. Analyze the first benefit: Fiber helps reduce the likelihood of constipation by adding bulk to stool and promoting regular bowel movements. Insoluble fiber, in particular, is effective in this role as it passes through the digestive system largely intact.
3. Examine the second benefit: Fiber may reduce the risk of colon and breast cancer. This is because fiber promotes the removal of waste and potentially harmful substances from the digestive tract, and it also supports the growth of beneficial gut bacteria, which may have protective effects.
4. Evaluate the third benefit: Fiber promotes overall bowel health by maintaining a healthy gut microbiome, reducing the risk of diverticular disease, and supporting the integrity of the intestinal lining.
5. Conclude that all the listed benefits are correct: Since fiber contributes to reducing constipation, lowering cancer risk, and promoting bowel health, the correct answer is 'All of the above.' This highlights the importance of consuming adequate fiber in the diet.
