Eggs contain all the essential protein, minerals and vitamins, except
Vitamin C. But egg yolks are one of few foods that naturally contain Vitamin D.
Eggs also contain choline, which is necessary for healthy cell membranes in the
body. Choline stimulates brain development and function and helps preserving
memory.
Eggs also are good for your eyes because they contain
lutein which helps prevents age-related cataracts and muscular degeneration. In
fact, eggs contain more lutein than spinach and other green vegetables.
The color of the egg shell is not related to quality, nutrients,
flavour, or cooking characteristics. White shelled eggs are produced by hens
with white feathers and white ear lobes. Brown shelled eggs are produced by
hens with red feathers and red ear lobes. Brown egg layers usually are slightly
larger and require more food, thus brown eggs usually cost more than white eggs.
An egg shell has as many as 17,000 pores over its surface. There are about 70 calories in an uncooked egg and 77
calories in a cooked egg.
How to determine whether an egg is fresh or hard boiled?
- Just spin the egg. If it wobbles, it’s raw. If it spins easily, it’s hard boiled.
- A fresh egg will sink in water, a stale one will float.
Egg (1) Very fresh , (2) A week old, (3) 3 weeks old & (4) 4 weeks old
