Eggs are a good source of high-quality protein that helps maintain and build muscles, while keeping you feeling fuller for longer when added to a meal.
Eggs are also a good source of B vitamins, as well as selenium – a micronutrient that helps your body make specific antioxidant enzymes and that assists with in preventing cell damage. Eggs are also rich in lutein and zeaxanthin – which are good for the eyes – and choline, which is needed for the brain and nerves.
Together with vitamin B12 and folate, choline plays a role in DNA synthesis and repair. It is also very important during pregnancy and breastfeeding, as studies have shown that choline helps to prevent neural-tube defects in babies, and has a long-term beneficial effect on memory and brain function.
Hens that are raised in pasture or fed feeds rich in omega-3 fatty acids will lay eggs that are high in omega-3 fatty acids – essential fatty acids that are linked to brain health and known for lowering a type of cholesterol called triglycerides in the bloodstream.
Moreover, eggs contain almost equal amounts of saturated and monounsaturated fats, and are high in dietary cholesterol, too.
