Eggs are rich in just about every nutrient, especially fat-soluble vitamins A and D. Eggs also provide sulfur-containing proteins, necessary for healthy cell membranes. They are an excellent source of special long-chain fatty acids called EPA and DHA, which make them a valuable brain food.
One of the most important substances in egg yolks is lecithin, which is vital for many of the body's metabolic processes, including the dispersal of fat deposits, as well as preventing the formation of gallstones and encouraging the speedy conversion of body fats into energy. Egg yolk is also the most concentrated known source of choline, a B vitamin found in lecithin that is necessary for keeping cholesterol moving in the blood stream.
They discovered that, despite being low in calories, eggs are a rich source of protein and are packed with essential nutrients thought vital to good health, particularly vitamin D, vitamin B12, selenium and choline.
The report also confirms that among protein foods, eggs contain the richest mix of essential amino acids - crucial for both children and young adults since a balance of amino acids is required for proper growth and repair.
The research team highlighted data from previous research in the US which found that people who ate eggs had higher intakes of all nearly all nutrients compared with non-egg eaters.
The lead author of the report said:
"Eggs are not only low in calories but are packed with nutrients that are essential to healthy living. They are an ideal food at every stage of life, as well as being easy to cook and enjoyable to eat.
One of the key findings of the report - entitled The Nutritional Properties and health Benefits of Eggs - is that eggs are an important dietary source of vitamin D and could significantly help to boost daily intake.
Tips for Using Eggs
When buying eggs, always choose organic, free range eggs. They are superior in both taste and nutrients. They contain more omega-3 fatty acids than that of battery-farmed eggs, and much higher levels of vitamin D and E. Also, the yolks of free-range eggs are usually a deep orange color, unlike the pale yellow yolks of battery eggs, showing that they have a much higher beta carotene content.
