Question

Which of the following is also known as roughage?
A) Fibres
B) Carbohydrates
C) Fats
D) Vitamins

Answer 1

Hint: Roughage is also known as dietary fibre is the portion of plant-derived food that cannot be broken down completely by the human digestive enzymes. Dietary fibres are diverse in chemical composition and can be categorized by their solubility, viscosity and fermentability, which affects how the fibres are processed in the body.

Complete answer:
As we know roughage is basically an edible fibre that has the capacity to resist the enzymes of the human digestive system. It also helps in the proper elimination of waste products. Dietary fibre has two main components such as the soluble fibre and insoluble fibre, which are components of plant foods, such as legumes, whole grains and cereals, vegetables, fruits, and nuts or seeds. A diet that is high in regular fibre consumption is associated with supporting health and lowering the risk of several diseases.
Examples include whole grains like oats and vegetables like carrot and cucumber.

- Carbohydrates are present in a variety of natural and processed foods. Starch is a polysaccharide and is abundant in cereals, potatoes, and processed food based on cereal flour, such as bread, pizza or pasta.
- Fats refers to triglycerides, which are the main components of vegetable oils and of fatty tissue in animals.
- Vitamin is an organic molecule that is an essential micronutrient that an organism needs in small quantities for the functioning of its metabolism.
- Hence, we can say that options B, C and D are incorrect.

So, the correct answer is option ‘A’ i.e, Fibre.

Note: Food sources of dietary fibre is divided based on whether they provide soluble or insoluble fibre. Plant foods contain both types of fibre in different amounts, based on the fibre characteristics of viscosity and fermentability. The advantages of consuming fibre depend upon which type of fibre is being consumed and which benefits may result in the gastrointestinal system.
