Chapter 3. Mindful Eating: A Path to a Healthy Body

Chapter 3. Mindful Eating: A Path to a Healthy Body

Fats, vitamins, minerals, roughage, and water are equally important components of a healthy diet. Although they are required in different amounts, each of them performs a specific function that helps the body grow, remain healthy, and work efficiently. A balanced diet contains all these components in the right proportions to meet the nutritional needs of the body.

Detailed Notes

Fats

Fats are nutrients that provide energy to the body and also act as stored energy. When the body does not get enough carbohydrates, it uses stored fats as an alternative source of energy. Fats also help keep the body warm and protect important internal organs.

Sources of Fats

• Butter
• Ghee
• Cooking oils
• Nuts and seeds
• Milk and milk products
• Egg yolk

Functions of Fats

• Provide and store energy.
• Help maintain body temperature.
• Protect internal organs from injury.
• Help absorb fat-soluble vitamins.

Remember: Excess consumption of fats may lead to obesity and other health problems.

Vitamins

Vitamins are protective nutrients required in small amounts. They help the body remain healthy, support normal growth, strengthen immunity, and prevent deficiency diseases.

Vitamin	Important Sources	Main Function	Deficiency Disease
Vitamin A	Carrot, Spinach, Mango, Papaya	Healthy eyesight and skin	Night Blindness
Vitamin B1	Whole grains, Pulses	Healthy nervous system	Beriberi
Vitamin C	Orange, Lemon, Amla, Guava	Healthy gums and immunity	Scurvy
Vitamin D	Sunlight, Egg, Fish, Fortified Milk	Strong bones and teeth	Rickets

Minerals

Minerals are essential nutrients required for proper growth, healthy bones, formation of blood, and the normal functioning of the body. Although required in small amounts, they play an important role in maintaining good health.

Mineral	Main Function	Sources	Deficiency Disease
Calcium	Strong bones and teeth	Milk, Curd, Cheese	Weak bones
Iron	Formation of haemoglobin	Spinach, Jaggery, Pulses	Anaemia
Iodine	Proper thyroid function	Iodised Salt, Seafood	Goitre

Dietary Fibre (Roughage)

Dietary fibre, commonly called roughage, is the indigestible part of plant food. Although it does not provide nutrients or energy, it is essential for maintaining a healthy digestive system.

Functions of Roughage

• Helps food move smoothly through the digestive tract.
• Prevents constipation.
• Maintains a healthy digestive system.
• Promotes regular bowel movement.

Sources of Roughage

• Green leafy vegetables
• Fresh fruits
• Whole grains
• Salads
• Sprouts

Water

Water is one of the most essential components of our diet. It is required by every cell of the body and is necessary for almost all life processes.

Functions of Water

• Helps in digestion.
• Transports nutrients to different parts of the body.
• Removes waste materials through urine and sweat.
• Regulates body temperature.
• Prevents dehydration.

Sources of Water

• Drinking water
• Milk
• Fresh fruits
• Vegetables
• Soups and juices

Balanced Diet

A balanced diet is a diet that contains carbohydrates, proteins, fats, vitamins, minerals, dietary fibre, and water in the right proportions according to the body's needs. It provides energy, supports growth, repairs damaged tissues, strengthens immunity, and keeps the body healthy.

Characteristics of a Balanced Diet

• Contains all essential nutrients.
• Includes roughage and sufficient water.
• Provides adequate energy.
• Supports normal growth and development.
• Prevents deficiency diseases.

Deficiency Diseases

When the body does not receive sufficient amounts of a particular nutrient over a long period, deficiency diseases may develop.

Nutrient Deficiency	Disease	Main Symptoms
Vitamin A	Night Blindness	Difficulty seeing in dim light
Vitamin B1	Beriberi	Weak muscles and nerve problems
Vitamin C	Scurvy	Bleeding gums and poor wound healing
Vitamin D	Rickets	Weak and soft bones
Iron	Anaemia	Tiredness and weakness
Iodine	Goitre	Swelling of the neck

Remember Points

• Fats provide stored energy.
• Vitamins and minerals are protective nutrients.
• Roughage keeps the digestive system healthy.
• Water is essential for all life processes.
• A balanced diet contains all nutrients in the correct proportion.
• Deficiency diseases can be prevented by eating a nutritious and balanced diet.
