Eggs are a favorite snack of mine, especially since I've been hitting the gym more. Eggs are a nutrient rich food, each containing 13 vitamins and minerals and are less than 70 calories each. Their protein content is excellent for being such a small food. They're even healthier if you can find a local, cage-free, free range source of eggs. But it's hard to tell if your eggs have gone bad. How do you tell if your eggs are rotten?

Eggs, as good as they are, can be a little bit tricky. Unless you saw it come out of the hen, you can't ever really be sure how old they are. Eggs also go through a jarring washing process that can sometimes cause micro-cracks in them, leading to rapid loss of quality. So how do we know if our eggs are rotten? There's a simple test.

First, take a bowl, a larger one if you have one, and fill it with cold water. Don't use warm water! Only cold tap water. Place the egg in the water. if it sinks, the egg is good. If it floats, toss it. It's not a good egg anymore. Of course, there's also the smell test, where if the egg doesn't smell right anymore don't use it. But the float test is the best one. Why? As eggs age, some of their liquid evaporates, leaving a larger bubble of air in the egg.

But how do we keep eggs from going bad so fast?

One way to keep your eggs from going bad so fast is to simply buy fresher eggs. Kind of a no-brainer, right? Eggs that come from a fresh, local source will naturally last longer. Fresh eggs can go unrefrigerated for about 10 days before they start going bad and, if refrigerated in time, will stay good for WEEKS longer than store bought eggs.

You should also not opt to store eggs in the egg compartment in the door. The door of the fridge is subject to the most radical temperature changes, which cause your eggs to spoil faster.
