The egg is one of the most complete foods there is: it provides excellent quality protein, essential vitamins, minerals, and a feeling of fullness that few other foods can match. That’s why it’s such a popular choice for breakfast or to break a fast. However, certain habits in its consumption and storage can diminish its nutrients, promote bacterial growth, and even cause inflammation.
How to tell if an egg is fresh?

There’s a very simple trick:
Fill a glass with water.
Put the egg in.
If it sinks and lies horizontally, it’s a fresh egg.
If it floats, it’s an old egg. In that case, it’s best to use it as soon as possible or discard it.
This test works because over time, the contents of the egg lose moisture and the internal space fills with air, causing it to float.
