QUESTION 9

Which of the following is not a property of fibre?
O a. It delays gastric emptying
Ob.it
It provides a feeling of satiety
O c It elevates blood glucose levels
O d. It contributes 6-10 kilojoules per gram.

Answer 1

c It elevates blood glucose levels

Step-by-step explanation:

Elevation of blood glucose levels is not the property of fiber because fiber helps control blood sugar. Fiber can't be converted into glucose or fiber does not have glucose so the concentration of glucose can not be increased if more fiber is eaten. Fiber provides a feeling of satiety as well responsible for gastric emptying. One gram of fiber produces 8 kilojoules per gram. So we can conclude that blood glucose level can't be increases due to fiber.

Answer 2

Answer: The correct option is C ( It elevates blood glucose levels).

Step-by-step explanation:

All animals feed on ready - made food. This food is made up of several groups of substances.All food taken in by an animal can be divided into six groups of food substances or nutrients. They are carbohydrates, proteins, fats and oil, mineral salts, vitamins and water.

Fibres is defined as foods that are usually of plant origin which are indigestible and stimulates movement of the bowels by providing bulk to the intestinal content.

Examples of the plant based food which are rich in fibre include:

--> grains,

--> fruits,

--> vegetables,

--> nuts, and beans.

Fibre is further divided into two:

--> Insoluble fibre: This is also called roughages. They include fruits and vegetables with their backs, whole grains.

--> Soluble fibre: This is the jelly-like fibre that dissolves in water. It includes the flesh of fruits and vegetables, oats.

All fibers can slow the absorption of sugar and fat from food, and therefore help prevent spikes in blood sugar. Therefore the option that fibre elevates blood glucose levels is NOT a property of fibre.
