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.

Nutritious Food

What Do We Eat?

People's food preferences are influenced by local availability, cultural traditions, and personal tastes. For example, rice is a staple in Asia, while bread is common in Europe.

Food in Different Regions

Different regions grow various crops based on the types of soil and climate.

• Knowing about these local specialities helps us appreciate India's rich cultural and agricultural diversity. 
• The food choices in each area vary according to the crops grown, local tastes, cultural influences, and traditions.

What are the Components of Food?

The components of food are the essential nutrients that our bodies need to function properly. These include:

Components of food

1. Carbohydrates

Carbohydrates are the primary source of energy for our body. They are essential for performing daily activities and bodily functions.
Carbohydrates can be found in:

Sources of carbohydrates

• 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.

2. Fats

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.

Why We Eat Laddoos in Winter?

Laddoos

In winter, our body needs extra energy to stay warm. Laddoos are a traditional food that helps us do just that. They are made from ingredients like besan (chickpea flour) or wheat flour (aata), ghee, goond (edible gum), nuts, and seeds. These ingredients are rich in fats, which provide stored energy that keeps us warm during the cold weather.
Examples of Fats in Laddoos:

• Ghee: A type of clarified butter that is high in fat and helps keep our body warm.
• Nuts: Such as groundnuts (peanuts), walnuts, coconuts, and almonds, which are rich in healthy fats.
• Seeds: Like pumpkin seeds and sunflower seeds, which also provide fats.

These fats not only give us energy but also help our body stay warm, which is why laddoos are popular in winter.

3. Proteins

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

Sources of Proteins

Proteins also play a key role in producing enzymes and hormones that regulate various body functions.

Some More Information

• Polar bears: Polar bears build up a significant amount of fat beneath their skin, which acts as an energy reserve. This fat helps sustain them through their long winter sleep (hibernation), allowing them to survive without food.
• Mushrooms: They typically grow in dark and moist environments. Edible mushrooms are rich in protein.
• Scurvy: Scurvy is a disease that causes symptoms like bleeding and swollen gums. In the past, sailors on long trips often got scurvy. In 1746, Dr. James Lind found that sailors who ate lemons and oranges, which are rich in vitamin C, got better and their symptoms improved.
• Goitre: Goitre is a disease that causes swelling at the front of the neck. In the 1960s, Indian scientists noticed this problem in people from the Himalayan region and Northern plains. It was found that the soil in these areas had little iodine, which led to a lack of iodine in their food and water. To solve this, iodised salt was introduced. Eating iodised salt helped reduce the swelling and symptoms of goitre.

4. Vitamins and Minerals

Vitamins and minerals are essential nutrients that support various bodily functions. They are required in small amounts but are crucial for maintaining health.

Importance of Nutrients in Our Diet

• Nutrients are the substances in food that give us energy, help us grow, repair our body, and keep us healthy. The main nutrients we need include carbohydrates, proteins, fats, vitamins, and minerals.
• Vitamins and minerals are special nutrients known as protective nutrients because they protect our body from diseases and keep us healthy. Foods like milk, green vegetables, fruits, and whole grains are good sources of these important nutrients. Even though we only need small amounts of vitamins and minerals, they are essential for our health.
• When we cook vegetables, you might notice that they sometimes lose their bright color or become softer. This happens because some nutrients, like vitamin C, can be lost when exposed to high heat. That's why it’s a good idea to also eat fruits and raw vegetables as part of our diet. However, it's important to wash all fruits and vegetables thoroughly before eating them to ensure they are clean and safe.

5. Dietary Fibres 

Dietary fibres are essential for digestion and excretion. They help in maintaining a healthy digestive system by promoting regular bowel movements.
Sources of dietary fibres include:

• Green Leafy Vegetables: Spinach, kale
• Fresh Fruits: Apples, oranges, berries
• Whole Grains: Brown rice, oats
• Pulses and Nuts: Lentils, almonds

6. Water 

Water is vital for all bodily functions. It helps absorb nutrients and remove waste from the body. Drinking adequate water daily is essential to stay hydrated and maintain bodily functions.

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.

2. Test for Fats

• 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.

3. Test for Proteins

• 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 a way of eating that gives your body all the nutrients it needs to work properly. This means eating a variety of foods in the right amounts.

Importance of a Balanced Diet

A balanced diet includes all essential nutrients in the right proportions. It ensures proper growth, development, and maintenance of the body.
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

It is important to adjust your diet to make sure all these nutrients are included.

Millets: Nutrition-rich Cereals

Millets are highly nutritious and easy to cultivate. They are rich in vitamins, minerals, and dietary fibres, making them an important part of a healthy diet.

MilletsExamples of millets include:

• Jowar (Sorghum)
• Bajra (Pearl Millet)
• Ragi (Finger Millet)
• Sanwa (Barnyard Millet)

Millets are beneficial for health as they help in managing diabetes, improving digestion, and reducing the risk of heart diseases.

Food Miles: From Farm to Our Plate

Food Miles: This term refers to the distance food travels from its source to the consumer. For instance, locally grown apples have fewer food miles than imported ones.

Food Miles

• Reducing Food Miles: We can reduce food miles by choosing locally grown produce and prevent food waste by taking only what we can eat. By reducing food miles, we can support local agriculture, reduce carbon footprint, ensure fresher and more nutritious food.
