MUST READ: 10 Things Eating An Egg Daily Will Do For You
Eggs are a very good source of inexpensive, high quality protein. More than half the protein of an egg is found in the egg white along with vitamin B2 and lower amounts of fat and cholesterol than the yolk. The whites are rich sources of selenium, vitamin D, B6, B12 and minerals such as zinc, iron and copper.
Helps the Heart
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.
Improves Your Productivity
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.
Helps 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.
Helps Your Eyes
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 zeaxanthine, 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 zeaxanthine is therefore very important from childhood onwards throughout the life cycle.
Boosts Your Immune System
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.
