Egg

Humans have eaten animal eggs for thousands of years. The most widely consumed eggs are those of fowl, especially chickens. Eggs of other birds, including ostriches and other ratites, are eaten regularly but much less commonly than those of chickens. People may also eat the eggs of reptiles, amphibians, and fish. 

Egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches.

Eggs are naturally rich in vitamin B2 (riboflavin), vitamin B12, vitamin D, selenium and iodine. They also contain vitamin A and a number of other B vitamins including folate, biotin, pantothenic acid and choline, and other essential minerals and trace elements, including phosphorus.

Maturation

The maturation of eggs typically takes about 14 days and can be divided into 2 distinct periods. During the initial period, many eggs, as many as 1000, begin to develop and mature. The second phase of development requires gonadal hormone stimulation to stimulate further development.

Geometric shape

The shape of an egg is approximated by the "long" half of a prolate spheroid, joined to a "short" half of a roughly spherical ellipsoid, or even a slightly oblate spheroid.

Fertilization

Contact between the egg and sperm is random. Once the egg arrives at a specific portion of the tube, called the ampullar-isthmic junction, it rests for another 30 hours. Fertilization — sperm union with the egg occurs in this portion of the tube. The fertilized egg then begins a rapid descent to the uterus.

Benefit of Eating Egg

Eggs are a nutritious protein source and a staple in many people's diets. Though they're high in cholesterol, they also have many health-promoting qualities. For healthy adults, eating 1–2 eggs a day appears safe, as long as they're consumed as part of an overall nutritious diet. Below, we've provided some of the proven key health benefits of eating eggs:

• Eggs Are Nutrient Rich.
• Eggs Provide Excellent Quality Protein.
• Eggs Improve Levels of “Good” Cholesterol.
• Eggs Provide A Great Source Of Vitamin D.
• Eggs Are Filling And Help With Weight Management.
• Eggs Are Among the Best Dietary Sources of Choline.
• In cooking and baking there are five main functions of an egg. They bind, thicken, coat, serve as a leavening agent, and emulsify. Egg whites can be whipped to create egg white foam.
• Eating eggs leads to elevated levels of high-density lipoprotein (HDL), also known as the “good” cholesterol. People who have high (HDL) levels have a lower risk of heart disease, stroke and other health issues. According to one study, eating two eggs a day for six weeks increased HDL levels by 10%.
•  Eggs are a nutrient-rich hair super food. Egg is rich in proteins, vitamins and fatty acids, which are all essential for a good hair health.  Vitamins A and E, biotin, and folate are just some of the nutrients that researchers have linked to hair growth and healthy hair.  Hence, it is actually good to apply egg on hair regularly! The most common nutritional deficiency in the world is iron.

Ways to cook egg

The possibilities are endless! The most common methods are scrambling, frying, baking, poaching, and boiling. Within these categories there are dozens of options—it's all just a matter of preference.

White Egg and Brown Egg

Do you have a preference when it comes to buying eggs? Do you opt for brown eggs more often assuming that they are healthier? Or do you stick to white eggs because that’s what you have always eaten? In the white egg vs. brown egg battle, there certainly is a difference in the color of the eggshells and sometimes in price, but are the differences just shell-deep? Read on to know all the details and facts you need to know to help you make an informed choice when buying eggs next time. People tend to opt for brown chicken eggs assuming they are the healthier version just like brown bread, brown rice, or brown pasta. However, that’s not true for eggs. The USDA states that the color of the eggs depends on the breed and genetics of the hens.

For example, chicken breeds such as the White Leghorn, White Rock, and Cornish lay white eggs, while Plymouth Rocks, Rhode Island Reds, and New Hampshire lay brown-shelled eggs. Few other chicken breeds like the Araucana, Lushi, Dongxiang, and Ameraucana lay blue-green or blue eggs. The difference in the non-white color of the eggshells is due to the pigments produced by that particular breed.
