What is recommended dietary allowance
The “Recommended Dietary Allowances (RDA)” are the safe intake levels of the essential nutrients. These levels are found to be adequate or sufficient to meet the nutrients requirement of nearly all healthy individuals in a specific life stage along with gender group.
( RDA INTAKE = NUTRIENTS REQUIREMENT + SAFETY MARGIN )
Every organism need a wide range of nutrients to lead a healthy and active lifestyle. The amount of each nutrient requirement for an individual depends on his/her age, body weight, physical activity, physiological states i.e. pregnancy, lactation etc. So, the requirement of all nutrients varies from individual to individual.
Nutrient requirement is the requirement of particular nutrient in the minimum amount that needs to be consumed by an organism. It is used for preventing from the symptom of deficiencies. Also, it is required to maintain adequate level of the nutrient in the body of an organism.

- It helps in designing, developing nutrition programmes and policies for health care policy makers and public health nutritionists.

We can say that the RDA is just like a minimum level of lubrication oil in our vehicle engine (Engine represents our body).
If lubrication oil level of vehicle engine is low, then engine will run for sometime but not for a long life.
In same way, if RDA is not followed by us, we will run for sometime but not for a long life.– Health Jaagran
