Chapter 3, Problem 55
Describe the properties of soluble fiber.
Verified step by step guidance1
Soluble fiber is a type of dietary fiber that dissolves in water to form a gel-like substance.
It is found in foods such as oats, peas, beans, apples, citrus fruits, carrots, barley, and psyllium.
Soluble fiber can help lower blood cholesterol and glucose levels, making it beneficial for heart health and diabetes management.
It slows down the digestion process, which can help with weight management by promoting a feeling of fullness.
Soluble fiber is fermented by bacteria in the large intestine, which can produce beneficial short-chain fatty acids.
