Answer 2

Answer:

Water​ is not a nutrient.

Explanation:

• The food components that provide essential nutrients are carbohydrates, fats, proteins, vitamins and minerals.

• The food components that do not provide any nutrients are water and roughage.

• The food we eat is composed of a wide distribution of nutrients which have very specific metabolic effects on the human body.

• Nutrients are generally classified into 2 categories, macronutrients and micronutrients.

• The majority of a person's diet should consist of macronutrients because they are required in relatively large amounts and "thereby give energy and the vital nutrients."

• Essential nutrients are those that the human body is unable to produce on its own and must therefore obtain from food sources.

• Essential nutrients include vitamins, minerals, amino acids, fatty acids and some carbohydrates as a source of energy that is needed for growth, maintenance and activity". Macronutrients include carbohydrates, proteins, fats, and macro minerals.

• Carbohydrates, proteins and fats refer to interchangeably as sources of energy.

• Micronutrients are vitamins and trace or microminerals. Vitamins and trace minerals are labelled as micronutrients because the body only requires them in very small amounts generally less than 100 mg/day.

• They possess a preventive and therapeutic role in our diet and provide no energy. "Vitamins are natural, organic chemicals that we consume together with food and which serve as "substances that help to stimulate various responses in the body."

• Trace minerals refer to inorganic substances that once ingested play a role in a "variety of metabolic processes and contribute to the synthesis of such elements as glycogen, protein and fats".      

• In addition to these nutrients, our bodies also require water and dietary fibre. The term "roughage" also applies to dietary fibres.

• The main source of roughage in our food is plant-based items. The main sources of roughage are potatoes, fresh fruits and vegetables, whole grains, and legumes.

• Although roughage is a necessary part of our diet and increases food's size, it does not deliver any nutrients to our bodies. This aids our body in eliminating uneaten meals.

• Our body needs water to absorb nutrients from food. Additionally, it aids in the removal of various bodily wastes including urine and sweat

Hence the correct option is water.
