Examples of food rich in Fats:
Oil, butter, nuts, avocado, olive, coconut, ghee, cheese, fish, animal meat, dairy products, etc.

New Words
Glucose: It is the main type of sugar present in the blood and is the vital source of energy for the body's cells. Glucose is synthesised from the foods we eat. Our body too can make it from other substances. Glucose is carried to the different cells of our body through the bloodstream.
Immunity:It is the body's ability to defend itself from diseases and infections. A good immunity is achieved if one eats food with the right amount of nutrients.
Misconceptions:
- Eating fat-rich food is not good for health.
It is not good when one is not using the energy produced by fats. Consuming fats should be accompanied by some physical activities. - Eating too often leads to weight gain.
Eating too often does not lead to weight gain. Gaining weight depends on the type of food one eats
