Human nutrition is about how the human body gets and uses food for energy, growth, and repair. It is a key topic that helps us understand the importance of a balanced diet and how our bodies stay healthy. Balanced Diet:

A balanced diet is a diet that contains all the nutrients our body needs in the right amounts. It may vary depending on things like their age, gender, and how active they are.

The Seven Main Nutrients:

• Carbohydrates: These are the main source of energy for the body.

• Proteins: These are used for growth and for repairing tissues.

• Fats: These provide a lot of energy and also help keep the body warm.

• Vitamins: These are needed in small amounts for a wide range of body processes.

• Minerals: These are also needed in small amounts for specific body functions.

• Water: This is vital for life. It helps transport nutrients and regulates body temperature.

• Dietary Fibre: This is a part of food that cannot be digested. It adds bulk to food, which helps it move through the digestive system and prevents constipation.

Malnutrition:

Malnutrition is a situation when a person’s diet does not have the correct amount of nutrients.

• Undernutrition: When someone consume too little nutrient. This can lead to diseases like scurvy, caused by a lack of Vitamin C, or rickets, caused by a lack of Vitamin D or calcium.

• Overnutrition: When someone consumes too much nutrient. This can lead to weight gain and conditions like obesity.
