e Cold Facts About Eggs When it comes to breakfast, eggs are undoubtedly a staple. Whether you prefer them scrambled, fried, poached, or boiled, these versatile little orbs add protein and flavor to any dish. But did you know that there are some surprising facts about eggs? Here are five cold facts about eggs that you may not have known. 1. The Color of the Eggshell Doesn't Affect Its Nutritional Value Many people believe that brown eggs are more nutritious than white eggs. However, this is simply not true. The color of an eggshell is determined by the breed of the chicken that laid it. Whether an egg is white or brown, its nutritional value is the same. 2. The Largest Egg Ever Laid Weighed More Than A Pound Most eggs are relatively small, weighing between 50 and 70 grams. However, there have been some notable exceptions. The largest egg ever laid was by a hen in the UK in 1956. That egg weighed a whopping 454 grams, or just over a pound. 3. The Yolk Color Can Indicate A Hen's Diet The color of an egg yolk can range from pale yellow to a brilliant orange-red. The reason for this difference is related to the hen's diet. Hens that are fed a diet that is high in carotenoids, such as those found in leafy greens, will produce eggs with a more vibrant yolk color. 4. Eggshells Are Highly Porous Believe it or not, eggshells are highly porous, with around 17,000 tiny pores covering their surface. These pores allow air and moisture to pass in and out of the egg, which is necessary for the developing embryo inside. However, it also means that eggs can absorb odors and flavors from other foods in the refrigerator. 5. The Eggshell Membrane Can Have Health Benefits The membrane between the egg white and the shell is often discarded when cracking an egg. However, this membrane is actually rich in collagen and contains several other nutrients that may be beneficial for joint and skin health. In conclusion, there is much more to an egg than meets the eye. From the color of the eggshell to the health benefits of the eggshell membrane, eggs are full of surprises. So next time you crack an egg for breakfast, remember these five cold facts and impress your friends and family with your newfound knowledge.
