What do you mean by nutrients Class 10?

In the context of Class 10 biology, nutrients refer to substances that are essential for the growth, development, and maintenance of an organism's body. They are obtained from the food we eat and play a crucial role in sustaining life and supporting various bodily functions.


There are several types of nutrients, each serving a specific purpose in the body. These nutrients can be broadly categorized into two groups:

Macronutrients: Macronutrients are required in larger quantities and provide energy to the body. They include:

a) Carbohydrates: Carbohydrates are the primary source of energy for the body. They are found in foods such as grains, fruits, vegetables, and legumes.

b) Proteins: Proteins are essential for the growth and repair of body tissues, as well as for the synthesis of enzymes, hormones, and antibodies. Good sources of protein include meat, fish, eggs, dairy products, legumes, and nuts.

c) Fats: Fats are a concentrated source of energy and help in the absorption of fat-soluble vitamins. They also play a role in insulation, protection of organs, and hormone production. Common sources of healthy fats include oils, nuts, seeds, and avocados.

Micronutrients: Micronutrients are required in smaller quantities but are equally important for maintaining overall health. They include:

a) Vitamins: Vitamins are organic compounds that are essential for various bodily functions. They are categorized as water-soluble vitamins (such as vitamin C and B-complex vitamins) and fat-soluble vitamins (such as vitamins A, D, E, and K). Different vitamins have specific roles, such as boosting the immune system, supporting vision, promoting bone health, and aiding in cell function.

b) Minerals: Minerals are inorganic substances that serve various functions in the body. Examples of minerals include calcium, iron, potassium, zinc, and magnesium. They are necessary for maintaining strong bones, regulating fluid balance, supporting nerve function, and participating in enzymatic reactions.

c) Water: Although not considered a nutrient, water is vital for the body's functioning. It helps in digestion, absorption, transportation of nutrients, removal of waste products, and regulation of body 

temperature.

It's important to maintain a balanced diet that includes all these nutrients in appropriate proportions. A deficiency or excess of certain nutrients can lead to various health problems, such as malnutrition, vitamin deficiencies, or chronic diseases.
