Nutrients play a vital role in helping us lead healthy lives. Recommended Dietary Allowance (RDA) is a metric widely followed today in many parts of the world. This metric prescribes the quantum needed to be taken for meeting the need for various essential nutrients. Read on for more insights into Recommended Dietary Allowance (RDA) and how it differs between genders, age groups, etc.

Intake of nutrients at an optimal level is a prerequisite for healthy living. Recommended Dietary Allowance (RDA) is an average measure for consumption of key nutrients, and is not a prescription for any medical condition. On the other hand, medical conditions necessitate intake of a mineral or nutrient at a larger proportion than normal. For instance, consumption of more amounts of vitamin C is helpful to fight lung related problems. Hence, RDA is not a treatment plan. In simple terms, it is what experts consider as the right quantum of intake for maintaining wellbeing and overall health.

Essential nutrients and the quantum of their intake are listed below; for easy reference, each of these nutrients is detailed one after another.
