Seen the humble egg recently doing the rounds for its impressive health credentials? Well Rightly so.

Eggs have been lauded as a fantastic way to give yourself a health boost should they be a central part of your diet. Not considered yet why eating eggs will bring immense benefits to your health? As a start, the two parts of an egg come with different niceties. In a whole eggs the Yolk comes with some unique goodness - containing over 90 percent of an egg’s calcium and iron while the egg white contains almost half the egg’s protein. But there is more to an egg that just that… see these 10 benefits below you will find in an egg diet.

1.   Eggs help to improve performance

Eggs have a high satiety index, meaning they make you feel full for longer. One large egg supplies 6g of high-quality protein and a large variety of essential nutrients, with the exception of vitamin C. This is why teaming up a fruit or orange juice with an egg and whole-wheat/low GI bread provides the perfect breakfast to perform well in a challenging environment.

2.   Eggs can help to iron out problems

Many people with mild iron deficiency experience vague symptoms of tiredness, headaches and irritability. Iron is the carrier of oxygen in the blood and plays an important role in immunity, energy metabolism and many other functions in the body. The iron in egg yolk is in the form of heme iron, the most readily absorbable and usable form of iron in food and more absorbable than the form of iron in most supplements.

3.   Eggs improve nutrient adequacy of the diet

The nutrient density of eggs makes them a valuable contributor to a nutritious diet. A study among egg vs. non-egg consumers revealed that the diets of the non-egg consumers were more likely to fall short of vitamins A, E and B12. Eggs contributed 10-20% of folate and 20-30% of vitamins A, E and B12 among egg consumers. This study demonstrates the important role one food can play in ensuring nutrient adequacy.

4.   Eggs do not increase blood cholesterol

In the 1990s, eggs received a lot of bad publicity due to their cholesterol content of 210mg per egg yolk. Numerous studies have clearly demonstrated the lack of a relationship between egg intake and coronary heart disease.

To put things into perspective, it is important to realise that foods high in fat, especially saturated and trans fatty acids have a far greater impact on heart health than cholesterol in food. Eggs should be recognised as an inexpensive, versatile and easily digestible source of protein.

5.   Eggs can help to promote weight loss

Eggs with toast have a 50% higher satiety index than regular breakfast cereals. Several studies have reported that starting the day with an egg breakfast increases satiety in overweight people and may help with weight loss.

In one study where a breakfast of bagels, cream cheese and yoghurt were compared to a breakfast of two eggs, toast and jam (same amount of kilojoules), the latter group stayed fuller for longer and reduced their kilojoule intake at lunch by 29%.

At 315kJ per large egg, eggs actually add few kilojoules for all the nutrients they provide. When teamed up with whole grains (for example whole-wheat bread) and fruit or vegetables they are a complete meal, readily available, easy to prepare and inexpensive, making them a useful tool in weight-loss programmes.

6.   Eggs help to promote brain health

Choline is a nutrient that facilitates brain development in the foetus and newborn as well as memory function even into old age. Eggs are an excellent dietary source of choline, and one egg per day will provide 28% of a pregnant woman’s choline requirement.

Choline is of extreme importance during pregnancy and lactation when the reserves can be depleted. At the same time, it is the critical period for foetal brain development and lifelong memory enhancement. In experiments with rats, memory function in the aged rat was in part determined by what the mother ate. Mothers, the message is clear – make a lifelong investment and eat your eggs!

7.   Eggs help to prevent cataracts and to protect eye sight

A good dietary intake of eggs, spinach and broccoli is associated with a significant decrease in cataracts (up to a 20% decrease) and age-related lens and retinal degeneration, the leading cause of blindness in the elderly (up to a 40% decrease).

Eggs are a good source of the antioxidants lutein and zeaxanthin, which play an important role in keeping the eyes healthy. It accumulates in the eye where these nutrients protect against some types of harmful, high-energy wavelengths of light. Getting enough lutein and zeaxanthin is therefore very important from childhood onwards throughout the life cycle.

8.   Eggs provide the best quality protein

Protein is one of the most important elements of our diet. Our bodies use protein to build new and repair old tissue. Eggs are champions at providing high-quality protein. Amino acids are the building blocks of protein. Nine of these amino acids cannot be manufactured by the body and must be derived from the diet. A complete protein food contains enough of these nine essential amino acids to promote growth and maintain body tissue.

Egg, milk and meat (including poultry and fish) proteins are all complete proteins, but egg protein is of the highest quality, with a rating of 100. Compared to eggs, milk is rated at 93 and fish and beef at 75. One egg has approximately the same protein content as 30g cooked meat, fish or poultry. And apart from being the most versatile and best source of protein in our diet, it is also the least expensive.

9.   Eggs can help to protect our bones

Eggs are one of the few natural food sources of vitamin D, our sunshine vitamin. Vitamin D is essential for calcium absorption and for maintaining optimum bone health. Eggs, therefore, play a supporting role in the prevention of osteoporosis together with dairy products, our main source of calcium.

10.                Eggs promote healthy hair and nails

The hair and nails reflect many biochemical imbalances and shortages in the body. Eggs can help to promote healthy hair and nails because of their high content of sulphur-containing amino acids and the wide array of vitamins and minerals.

Many people report faster-growing hair after adding eggs to their diet, especially if they were previously deficient in foods containing zinc, sulphur, vitamin B12 and vitamin A.
