In addition to studying the effects of eggs on heart health, researchers are also looking into other potential health benefits.

Eggs and your eyes. Egg yolks are a source of lutein and zeaxanthin, carotenoids that help keep eyes healthy and have been linked to a reduced risk of age-related macular degeneration. But the research is preliminary and inconsistent. For instance, a study in the Journal of Nutrition in 2006 found that women eating six eggs a week for 12 weeks had increased macular pigment, which is thought to protect the retina from the damaging effects of light and from age-related degenerative changes. In contrast, a study in the British Journal of Nutrition in 2017 found that while eating an egg a day (regular or enriched with lutein and zeaxanthin) for eight weeks increased blood carotenoid levels, there were no significant changes in vision or in pigments in the macula.

Eggs and cognition. In a 2017 study in the American Journal of Clinical Nutrition, middle-aged men in Finland without dementia were followed for 22 years, during which time they were given cognitive testsand asked about their diets. Egg intake was associated with improved performance on tests that assessed a variety of cognitive functions, but no link was observed between eggs or cholesterol intake and development of dementia, including Alzheimer’s disease, even among those with a gene variation(APOE4) that increases their risk.

Eggs and satiety. A number of studies over the years have supported the idea that eggs promote satiety, attributed to their protein. For instance, a small study in the FASEB Journal in 2016 found that healthy young adults felt fuller after eating one egg a day—and especially two eggs a day. And a 2017 study in Nutrients of 50 healthy young people found that eating two eggs a day for breakfastincreased satiety throughout the day, more so than eating a packet of oatmeal, and this was associated with lower blood levels of ghrelin, a hormone that increases appetite.
