Eggs are a great source of protein and numerous vitamins, minerals, fat, etc. In fact, very few foods share the same diverse nutrient makeup available in a single egg. Many of these are specifically needed for the health of the nerves and the brain.
Through the years, all fats have become public enemies, often blamed for an increased risk of heart disease. Eggs fell out of favor and people gravitated toward egg whites as a substitute. In truth, the yolk is where many of the vitamins and nutrients are found.
In the UK, on an average, 182 eggs are consumed per person annually. An egg contains 78 calories of energy. Around 259 eggs are laid by a hen. An egg comprises 1.7% of polyunsaturated fat, 3.2% of saturated fat, 4.4% mono saturated fat, 75% of water, 12.5% of protein and 0.9% of vitamins, minerals and salt.
