Answer:
estimated average requirement
Explanation:
Many people (if not almost everyone) believes that vitamins and minerals are good, and more of them are even better. But anything in excess, including good things can be bad for you. E.g. if you do not consume enough iron you might develop anemia, but excess iron can poison you.
The estimated average requirement (EAR) values are intake levels that meet at least 50% of the populations needs. Your individual requirement levels might vary depending on your height, weight, age or activity levels, but the EAR serves as a good starting point to calculate your own individual needs.
