Raw (unboiled) eggs vs Cooked eggs

When it comes to making a choice between eating egg raw or cooked, there are many things that need to be kept in mind.

This is a fact that upon cooking, a particular food experiences a certain amount of nutrient loss. The same is the case with eggs. 

Uncooked eggs

  • 33% more omega-3
  • 36% more vitamin-D
  • 33% more DHA
  • 20% more biotin
  • 20% more zinc
  • 23% more choline

But at the same time, raw eggs have many downsides as well. A little plus in the nutritional values of raw eggs does not actually cover for the downsides it has. 

Eating raw eggs on a daily basis may have the following disadvantages-

  • Poor digestibility
  • Reduced absorption of protein by 50%
  • Bacterial infection
  • Block biotin absorption

Cooked eggs

Cooked eggs are considered a much better option when we consider health, taste, flavor, and satiety as a whole. 

The protein absorption with cooked eggs increases to about 91% and also provides better biotin absorption with no bacterial infection possibilities.

Different ways in which you can cook eggs to enhance their health benefits and taste are-

  • Scrambled eggs
  • Boiled eggs
  • Poached eggs
  • Omelet
  • Egg bhurji

Out of all the different possibilities, you cook eggs, boiled eggs are the most beneficial for health.

The nutritional value of one large-sized hard-boiled egg (50 g) is as follows-

  • Energy- 77.5 Kcal
  • Protein- 6.3 g
  • Total lipids (fat)- 5.3 g
  • Carbohydrate- 0.56 g
  • Calcium- 25 mg

  • Vitamin A- 74.5 µg

Thus, boiled eggs provide you with pure nutrients with almost no calories. Also, boiled eggs are one of the best protein sources to be included in your post-workout meal or for a weight-loss diet.

Health benefits of eating egg

In context to its nutritional properties, the egg has numerous health benefits. 

  • An egg is a complete protein food containing all the essential amino acids. Thus, it helps repair and build tissue cells.

Proteins also help fight infections and keep the body fluids in balance. One to three eggs every day is considered a staple form of protein enrichment for the body.

  • The iron content in eggs is beneficial for the transfer of oxygen throughout the cells. It also helps prevent anemia.
  • Vitamin A is particularly good for the eyes and especially, night vision. Eggs contain a fair amount of A vitamin, thus aiding in maintaining good eye health.
  • Eggs are a prominent source of calcium and phosphorus. Including eggs in your diet thus strengthens your bones and teeth.

Moreover, optimum calcium amounts in your body help prevent auto-immune diseases and cancers.

  • Eggs serve as a great source of Vitamin B12. This vitamin helps in RBC formation, maintaining the CNS functions, and aids in DNA formation.
  • Choline is one of the most essential nutrients required by the body for gene expression and maintaining the cell structure. Egg yolks are high in choline. There is no choline present in egg whites.
  • It’s a worldwide notion that consuming eggs can lead to heart diseases due to the high cholesterol content in them.

Busting the myth apart, the dietary cholesterol present in eggs has very little effect on blood cholesterol levels. 

One egg every day would literally cause no harm to you. The problem arises when you are consuming way too many eggs on a daily basis.

Types of edible eggs

Yes, there are eggs other than hen eggs! 

There are many types of edible eggs that are as nutritious and savory as hen eggs. And people around the world consume these other eggs with addition or apart from hen eggs. Some common types are-

  • Chicken eggs

Probably the king of the egg world, chicken eggs are one of the most popular and commonly consumed types of eggs.

They are rich in protein, calcium, and zinc. Generally, you can find them as white eggs and brown eggs in the market.

  • Duck eggs

Duck eggs have a slightly bigger yolk than chicken eggs. They are a rich source of fat and proteins. 

Chicken eggs are said to be thick-shelled and thus their shelf life is known to be longer than other eggs.

  • Goose eggs

Goose eggs are enormous in size, probably double the size of chicken eggs. Additionally, they also have a higher amount of protein out of all the other eggs.

The shell of goose eggs is quite hard and these eggs aren’t available very easily. This is because the goose itself lays a very less number of eggs in a year.

  • Turkey eggs

Turkey eggs have a creamy taste, especially with their yolk. They are a rich source of calcium and protein. 

  • Ostrich eggs

Ostrich eggs are the largest eggs ever known. They have a very hard shell and are around 20 times thicker than an average chicken egg.

Designer eggs: The new trend

Apart from these, the recent trend that can be seen quite often is organic eggs. These eggs are produced from a hen. 

The only difference is that the hens are only fed on organic feeds and are not injected with any antibiotics, injections, or hormones. Thus, the resulting eggs produced are completely organic.

The taste of organic eggs is slightly off than the regular ones but they are stepping up the game by ensuring the safety and quality quotient.

Fortified eggs are also booming within the market. The hen’s feed is mixed with certain additional sources of nutrients that need to be enriched in the egg, for example- Vitamin D, omega-3, etc.

How to know if the egg is fresh: Quick hacks

  • To check if the eggs are fresh or not, make sure you read the ‘best before date before you buy them and also before you start using them.
  • You can do a float test. Place the egg in a bowl of water, if it sinks the egg is fresh. If it floats, it means the egg is old.
  • If an egg is stale, the smell will say it all. All you need to do is crack it.
  • Crack an egg into a plate. If the yolk is flat and the white part runny, the egg is old. If the yolk stands uptight and the white part does not seem to be floating, the egg is fresh.

Eggs are a versatile food. They can be eaten in many different forms enhancing their flavor and taste. The good part is we do not need to compromise on the nutritional benefits.
