Understanding the balanced diet

A balanced diet includes five food groups that collectively fulfills all the nutritional needs of a person. 

Eating a balanced diet helps you to maintain a good health and cuts down the risk of developing many types of diseases.

Balanced diet is referred to as  balanced because it provides the body the right amount of calories and nutrients required to stay healthy.

The best way to get a balanced diet is to fill your plate  half with grains and protein and the other half with fruits and vegetables. It should also include low fat dairy product to provide nutrients found in dairy. 


Five food groups in a balanced diet

To have a balanced diet you can  include foods from the five groups:below: 

  • Vegetable

  •  Fruit

  •  Grains

  •  Protein

  •  Dairy products  



 This  group includes five subgroups

  • Green leafy vegetable 

  • Red and orange vegetable 

  • Starchy vegetables

  • Beans and peas

  • Other vegetables such as brinjal,  bottle gourd, okra etc.

To stay healthy  and ensure that your body get every kind of nutrients, you should include a variety of vegetables in your diet according to seasonal availability. Vegetables are versatile in the sense that they can be eaten  raw or cooked. However you have to understand that some vegetables lose their nutritional value when cooked. Likewise there are also vegetables that should be cooked  in order to make their nutrients bioavailable. Avoid deep frying vegetables or adding unhealthy amounts of fats. 



You should eat plenty of seasonal fruits.  They are nutritional powerhouses. Instead of drinking fruit juice,  you should eat whole fruits. Juice contains less nutrients than fruits. Fruits also supply body dietary fibre which is good for stomach health. 



There are two subgroups in grains i.e.  whole grains and refined grains.

Whole grain include all the three parts of the grain such as bran, germ, and endosperm. As  a result our body takes longer time to breakdown whole grains. Thereby it has less effect on the person’s blood sugar. Moreover whole grain contain more fibre and protein than refined grain, and it is good for digestive health. 



Protein is an essential part of a balanced diet. You should include protein in your regular diet. Protein is essential for muscle development, hormones formation and to support other body functions. Good sources of protein includes lean beef, pork, chicken, fish, beans, peas, and legumes.


Dairy products

Dairy is an important source of calcium. If you are struggling with overweight, you should prefer low-fat versions of dairy products. Some dairy healthy products  includes ricotta or cottage cheese, low-fat milk and yogurt.
