Final answer:
True. Fiber speeds up the movement of foods through the upper digestive tract and promotes a feeling of fullness. The claim that fiber speeds up digestion and promotes fullness is true. Fiber, which is present in plant-based foods, assists in moving food through the digestive system more efficiently and also helps prevent constipation. Additionally, fermentable fiber can help create a feeling of satiety.
Step-by-step explanation:
True or False. Fiber speeds up the movement of foods through the upper digestive tract and promotes a feeling of fullness.
True. Fiber is a carbohydrate that provides bulk for the muscles of the digestive tract to squeeze against. This squeezing helps speed the passage of food through the digestive system. Fiber also promotes a feeling of fullness by delaying gastric emptying and absorbing water, resulting in an extended feeling of satiety.
The claim that fiber speeds up digestion and promotes fullness is true. Fiber, which is present in plant-based foods, assists in moving food through the digestive system more efficiently and also helps prevent constipation. Additionally, fermentable fiber can help create a feeling of satiety.
The statement that fiber speeds up the movement of foods through the upper digestive tract and promotes a feeling of fullness is True. Dietary fiber is a type of carbohydrate that travels through our digestive system without being digested or providing energy. It is found in plant-based foods, such as vegetables, fruits, and whole grains. Fiber adds bulk to the diet, aiding muscles in the digestive tract to move food more quickly through the system, which can help prevent constipation. Insoluble fiber, which includes cellulose, increases peristalsis - the involuntary constriction and relaxation of muscles that moves food through the digestive system. Soluble or fermentable fiber absorbs water and can become a gelatinous substance that promotes satiety, or the feeling of fullness, and delays gastric emptying. This action on digestion aids in reducing the absorption of substances like cholesterol into the bloodstream and lowering the risk of conditions like colon cancer.
