Introduction
Healthy Eating is essential for maintaining good health and overall well-being. A healthy diet includes a variety of foods that provide essential nutrients in the right quantities. This includes carbohydrates, proteins, fats, vitamins, and minerals. Eating wholesome food in moderate quantities and considering factors like season, time, and place is crucial for a healthy lifestyle.
Food habits and culinary practices
People in different parts of India eat different kinds of food. This depends on the crops grown in that area, the culture, and the traditions.

Nutrients in food
Nutrients are substances in food that our body needs to grow, repair, and stay healthy.
The main nutrients are:
1. CarbohydratesCarbohydrates are the primary source of energy for our body. They are essential for performing daily activities and bodily functions.
Carbohydrates can be found in:
- Cereals: Wheat, rice, maize
- Vegetables: Potato, sweet potato
- Fruits: Banana, pineapple, mango
These foods provide the necessary fuel for our muscles and brain to function efficiently.
Fats provide stored energy and are crucial for the absorption of vitamins. They also help in maintaining healthy skin and hair.
Sources of fats include:
- Nuts and Seeds: Almonds, sunflower seeds
- Dairy Products: Ghee, butter, curd, milk
- Oils: Olive oil, sunflower oil
While fats are essential, consuming them in moderation is important to avoid health issues like obesity and heart disease.
Proteins are vital for growth, repair, and maintenance of body tissues. They are the building blocks of muscles, skin, and bones.
Proteins can be obtained from:
- Plant Sources: Pulses, beans, peas, nuts
- Animal Sources: Milk, paneer, eggs, fish, meat
Proteins also play a key role in producing enzymes and hormones that regulate various body functions.
Vitamins and minerals are essential nutrients that support various bodily functions. They are required in small amounts but are crucial for maintaining health.
Vitamins and Minerals: Functions, Sources, Deficiency Diseases, and Symptoms

How to Test Different Components of Food?
1. Test for Starch- To test for starch in food, an iodine solution can be used.
- When iodine is added to a food sample, a blue-black colour indicates the presence of starch.
- This is a simple way to identify foods that are rich in carbohydrates.
- To test for fats, place a food sample on a piece of paper and press it.
- If an oily patch appears, it indicates the presence of fats.
- This test helps in identifying foods that contain significant amounts of fat.
- To test for proteins, a mixture of copper sulphate and caustic soda solutions is used.
- A violet colour in the mixture indicates the presence of proteins.
- This test is useful for identifying foods that are rich in protein.
Balanced diet
A balanced diet is one that has all the nutrients our body needs. It should also have enough roughage and water. Eating a balanced diet keeps us healthy and helps us grow properly.
A balanced diet should include:
- Carbohydrates: For energy
- Proteins: For growth and repair
- Fats: For energy and vitamin absorption
- Vitamins and Minerals: For overall health
- Dietary Fibres: For digestion
- Water: For hydration
Junk food
- Junk foods are unhealthy because they have a lot of fat and sugar but not enough of other important nutrients.
- Eating too much junk food can make us gain weight and fall sick.
- We should eat junk food only sometimes and in small amounts.
Millets
- Millets are special kinds of grains that are very good for our health.
- Examples of millets are jowar, bajra, and ragi.
- They have lots of nutrients like vitamins, minerals, and fibre.
- Eating millets can help us stay healthy.
Food miles
- Food miles mean how far the food has travelled from where it is grown to where it is eaten.
- We should try to eat food that is grown nearby.
- This helps reduce pollution from transporting the food and supports our local farmers.
Avoid wasting food
- We should not waste food because a lot of hard work goes into growing and cooking it.
- We should take only as much food as we can eat.
- Wasting food is not good for the environment.
Terminology
1. Health- A state of complete physical, mental, and social well-being.
- Culinary practices are the ways in which we prepare and cook food.
- This includes the ingredients we use, the utensils and stoves we cook on, and the recipes we follow.
- Different regions have different culinary practices based on their culture and traditions.
- Nutrients are the parts of food that our body needs to grow, repair itself, and stay healthy.
- They are like the building blocks of our body.
- The main nutrients are carbohydrates, proteins, fats, vitamins, and minerals.
- Diseases are conditions that affect the normal functioning of the body, causing symptoms like fever, pain, weakness, or difficulty in performing daily activities.
- They can be caused by various factors like infections, nutrient deficiencies, genetic disorders, or unhealthy lifestyle choices.
- Examples of diseases include the common cold, diabetes, cancer, and heart disease.
- Deficiency diseases are illnesses that happen when we don't eat enough of certain nutrients.
- For example, if we don't eat enough Vitamin C, we might get a disease called scurvy which causes bleeding gums and slow healing of wounds.
- Scurvy is a disease caused by a lack of Vitamin C in the diet.
- It can cause symptoms like weakness, fatigue, joint pain, and bleeding gur
- In the past, sailors on long sea voyages often suffered from scurvy because they didn't have access to fresh fruits and vegetables.
- Today, scurvy is rare because most people get enough Vitamin C from their diet.
- Goitre is a condition where the thyroid gland in the neck becomes enlarged, causing a swelling in the front of the neck.
- It is often caused by a lack of iodine in the diet.
- Iodine is important for the proper functioning of the thyroid gland. In many countries, iodine is added to table salt to prevent goitre.
- A balanced diet is a way of eating that includes all the different nutrients our body needs, in the right amounts.
- It's like having a team of different players, each doing their part to keep our body healthy.
- A balanced diet should have carbohydrates, proteins, fats, vitamins, minerals, roughage, and water.
- Roughage, also called dietary fibre, is the part of plant foods that our body can't digest.
- It's like a broom that cleans our stomach and intestines, helping to keep our digestive system healthy.
- Fruits, vegetables, and whole grains are good sources of roughage.
- Junk foods are foods that have a lot of fat, sugar, or salt, but not much of other nutrients like vitamins and minerals.
- They might taste good, but eating too much of them is not good for our health. Examples of junk food are candy, chips, and soda.
- Fortification means adding extra nutrients to food to make it healthier.
- It's like giving food a nutrient boost.
- For example, milk can be fortified with Vitamin D, and salt can be fortified with iodine to prevent iodine deficiency.
- Macronutrients are nutrients that our body needs in large amounts.
- They provide energy and help in growth and development.
- The three main macronutrients are carbohydrates, proteins, and fats.
- We need to eat a balance of these macronutrients to stay healthy.
- Micronutrients are nutrients that our body needs in small amounts, but they are still very important for our health.
- Vitamins and minerals are micronutrients.
- They help in various body functions and protect us from diseases.
- Examples of micronutrients are Vitamin A, Vitamin C, iron, and calcium.
- Anaemia is a condition where our blood doesn't have enough healthy red blood cells to carry oxygen to all parts of the body.
- This makes us feel weak and tired. Iron deficiency is a common cause of anaemia.
- Eating iron-rich foods like green leafy vegetables, meat, and eggs can help prevent anaemia.
15. Dietary fibres
- Dietary fibres are the parts of plant foods that our body can't digest or absorb. They are important for keeping our digestive system healthy.
- There are two types of dietary fibres soluble and insoluble.
- Soluble fibres dissolve in water and help control blood sugar and cholesterol.
- Insoluble fibres don't dissolve in water and help prevent constipation.
- Nutrient-dense foods are foods that have a lot of nutrients compared to the number of calories they have.
- They provide a lot of vitamins, minerals, and other important nutrients without adding too many calories.
- Examples of nutrient-dense foods are fruits, vegetables, whole grains, lean meats, and low-fat dairy products.
17. Processed foods
- Processed foods are foods that have been changed from their original form for convenience and safety reasons.
- They are usually packaged in boxes or bags, ready to eat or heat, and have a list of ingredients on the label.
- Some processed foods have added sugars, salt, and fats, and may not be as nutritious as whole, unprocessed foods.
- Obesity is a condition where a person has excessive body fat that may negatively impact their health.
- It can increase the risk of various diseases like diabetes, heart problems, and certain cancers.
- Obesity often results from eating more calories than the body burns, combined with lack of physical activity.
- Maintaining a healthy weight through balanced diet and regular exercise is important.
- Starch is a type of carbohydrate found in many plant-based foods like grains, potatoes, and peas.
- It is an important source of energy for the body.
- When we eat foods containing starch, our digestive system breaks it down into simpler sugars, which our body can then use for energy.
- Malnutrition is a condition that occurs when a person doesn't get enough nutrients or gets too much of certain nutrients.
- It can lead to health problems like stunted growth, weak immune system, and poor cognitive development in children.
- Malnutrition can result from not eating enough food, not eating a variety of foods, or having an underlying health condition that affects nutrient absorption.
- The food pyramid is a visual guide that helps us understand how much of each food group we should eat for a balanced diet.
- The base of the pyramid includes foods that we should eat the most, like whole grains and vegetables.
