Claim:

Brown eggs are much healthier than white eggs

Fact:

There is no difference between the nutritional value of a brown or white egg

Eggs are an excellent source of high nutrition, since they provide all vitamins except Vitamin C. They also contain macronutrients such as lipids, carbohydrates, and proteins. Further, eggs are also a source of minerals such as phosphorus, calcium, potassium, sodium and trace elements including copper, iron, magnesium, manganese and zinc. Despite their excellent nutritional profile, each egg adds only 70 calories to your diet.

Like many other commodities, eggs are marketed in both regular and premium quality, with a corresponding price differential that is designed to maximize profits. Eggs are usually marketed based on the colour of their shells—white Vs tan or brown - with the latter being billed as more nutritious, and so deserving of a higher price.   

What decides colour of egg shell: 

Colour of an egg shell is determined by the breed of the hen with the colour of a hen’s ear area indicating the colour of its eggs. A white or a light spot indicates white eggs and a brown spot suggests tan shells. The colour of the egg shell ranges from white to deep brown.

Why are brown or tan-shelled eggs priced higher? 

Brown eggs are laid by hens of a bigger size, which require more resources for their upkeep, breeding and feeding.  This makes the process of harvesting brown eggs more costly. 

Is there a difference in the nutritional content of the two eggs types? 

The colour of the shell does not determine the nutrient content of the egg. Also, the claims that eggs of Araucuna breed of hens contain less cholesterol than other hens has not been proven.
