The main purpose of preparing a balanced diet is to supply all the required nutrients through a proper combination of various foods. To prepare such a balanced diet, one must have a clear understanding of the different food components. However, for an ordinary person, it is difficult to measure each food accurately every day to create a balanced diet.Considering these factors, nutrition experts have classified different types of foods into specific groups, which make it easier to prepare a balanced diet. These are known as Basic Food Groups or the Daily Food Guide.

These are known as Basic Food Groups or the Daily Food Guide.

To correct misconceptions and make food selection easier for the general public, foods have been grouped based on their nutrient content and functions. These groups are collectively called the Basic Food Groups.
The classification is mainly based on three factors:
Providing energy as a source of heat and work.
Supporting body growth and overall development.
Protecting the body from harmful environmental effects.

The Four Basic Food Groups চারটি মৌলিক খাদ্য গোষ্ঠী
1.Body-Building Foods (Protein-Rich Foods):
These foods are rich in high-quality protein and also supply important minerals like iron, calcium, phosphorus, and vitamins such as A and B-complex.
Examples:
1.Fish: Various small, medium, and large fish; dried fish; salted fish.
2.Meat: Beef, mutton, goat meat, duck, chicken, pigeon meat.
3.Eggs: Duck, chicken, and quail eggs.
4.Milk & Dairy Products: Cow, buffalo, and goat milk; curd; cottage cheese; buttermilk; sweets; paneer.
5.Pulses: Green gram (mung), red lentils (masoor), peas, black gram, chickpeas, pigeon peas.
6.Nuts: Peanuts, cashew nuts, etc.

2.Energy-Giving Foods (Cereal Group):
These provide the major source of energy for daily activities.
Examples: Rice, wheat, maize, bread, and other cereal products.

Maintains proportional distribution of energy from major nutrients:
1.Carbohydrates: ~65% (about 500 g)
2.Proteins: ~10% (about 70 g)
3.Fats: ~25% (about 70 g)

Calorie Breakdown:
•Carbohydrates: 500 g × 4 kcal = 2000 kcal
•Protein: 70 g × 4 kcal = 280 kcal
•Fat: 70 g × 9 kcal = 630 kcal
Total = 2910 kcal (approx.)

The approximate energy contribution from fats in a balanced diet can be calculated as follows:Amount of fat: 70 g
Energy provided by fat: 9 kcal per gram
Energy from fat=70g×9kcal/g=630kcal

Food Plan for Infants শিশুদের জন্য খাদ্য পরিকল্পনা
For the first six months after birth, the baby should be exclusively breastfed. After that, breast milk alone is not sufficient to meet the growing nutritional needs, as the baby's weight doubles by 5 months and triples by 12 months. Therefore, complementary foods should be introduced along with breast milk.
Rules for Complementary Feeding:
Continue breastfeeding up to 2 years.
Start complementary foods after 6 months of age.
Food should be balanced, easily digestible, fresh, and without spices.

Key Nutrient Requirements
1. Calories
Total energy requirement increases significantly during pregnancy to support fetal growth.
Over 280 days of gestation, a mother requires approximately 75,000–80,000 kcal in total.
Daily additional calorie requirements:
First trimester: +100 kcal/day
Third trimester: +350 kcal/day
Energy needs depend on adequate calorie intake and physical activity.
Increased calories are required due to factors such as enhanced thyroid activity.
For healthy women, 36 kcal per kg body weight/day is recommended.
Insufficient calories may lead to hypoglycemia, as the fetus consumes the majority of maternal glucose.

Insufficient calories may lead to hypoglycemia, as the fetus consumes the majority of maternal glucose.

2. Protein
Protein demand is highest during pregnancy for fetal tissue and organ development.
Maternal tissues, including the uterus and other cells, also grow during this time.
The body efficiently uses dietary protein for fetal and maternal growth.
Estimated additional protein needed per pregnancy: 900–950 g total.
First trimester: Minimal fetal growth → lower additional protein requirement.
Next 6 months: Daily extra 6 g of ideal protein or 10 g high-quality animal protein recommended.
Plant protein: 10–15 g/day recommended.

Nutrient Transfer from Mother to Fetus:
Nutrients pass from maternal blood to fetal blood through the placenta.
Methods of transfer:
Diffusion: Oxygen, water, and small molecules move passively.
Active transport: Glucose, amino acids, calcium, iron use energy to move.
Facilitated diffusion: Some nutrients use carrier proteins to cross.
Fetal nutrition depends entirely on maternal nutrition.

(4) Milk and Milk Products Group
Milk is considered an ideal and essential food for children, which is why it has been placed in a separate group. Milk provides high-quality protein, calcium, vitamin D, and riboflavin, which are vital for growth and development. For infants, mother’s milk is the best food. After 5–6 months, milk should be supplemented with other foods.

Pathya (therapeutic diet): 
পথ্য (চিকিৎসামূলক ডায়েট):
The food that is suitable and permissible for a sick person or patient is called Pathya. The quantity and type of food depend on the nature of the disease and the patient’s needs.
Pathya plays an important role in alleviating illness and, in many cases, serves as the only method to control the disease.
The scientific use of food for treatment is called Diet Therapy (therapeutic diet). Alongside medication, appropriate dietary management is crucial for the recovery from many illnesses. In many cases, disease recovery is not possible without a proper diet plan.

Planning of therapeutic diet
Any food acceptable for the body to replenish its losses is called Pathya. In a diseased condition, food given to a patient according to special requirements is called Pathya. A proper Pathya serves as an important treatment for the patient.
For a patient, first comes medicine, then Pathya. As the critical phase passes, the need for medicine gradually decreases while the need for appropriate diet increases.
Since digestion weakens during illness, Pathya is prepared with easily digestible and nutritious food. Without proper Pathya, diseases like Kwashiorkor, Anemia, Diabetes, Jaundice, etc., cannot be effectively treated or controlled.
Main functions of Pathya:
Replenish body loss and promote growth
Produce heat and energy in the body
Maintain the body’s health and strength
