The research review, to be published in the June issue of Complete Nutrition, highlights growing scientific literature linking regular egg consumption with tangible outcomes such as weight management, muscle function and vascular health.
“The evidence is pointing to a specific role for eggs in health, as nature’s very own multivitamin,” says report author Dr Carrie Ruxton. “This may mean that health professionals could be justified in actively promoting the consumption of eggs.”
Eggs contain nutrients deficient in many population groups
The paper highlights that, as well as containing high quality protein and fatty acids, there are a number of key nutrients found in eggs – including vitamin D, B vitamins, selenium, iodine and choline – that are not present in many other foods, and in which many population groups are known to be deficient.
The research review confirms that eggs have been shown to help with weight management, with several studies showing that the consumption of eggs can influence hunger and satiety as well as appetite hormones. One recent study suggested that the balance of amino acids in egg protein may mean it is metabolised more slowly than in other protein-rich foods, hence producing a different profile of hormones.
Eggs help with diabetes and cognitive performance
Emerging research has shown that eggs may have a positive impact on health in people with Type 2 diabetes; and there are several areas in which they may benefit the health of older people. One recent study showed that egg intake may have a beneficial association with cognitive performance in older people, and eggs can also play an important role in boosting the protein content in the diet of older people at risk of sarcopenia (muscle wastage).
The affordable superfood
Dr Carrie Ruxton adds: “As recent government data show, eggs are a veritable natural pharmacy of vitamins, minerals, fatty acids and protein, putting them on a par with most of today’s superfoods. Yet eggs are much more affordable and versatile.”
