Why Women Over 40 Are Suddenly Eating More Eggs Again

For decades, eggs sat in a nutritional grey zone, something people ate despite warnings and felt vaguely guilty about every time they cracked one open. Cholesterol concerns, confusing headlines, and decades of low-fat diet culture pushed a generation of women toward egg-white omelets and away from the yolk entirely.

That era is coming to a quiet close, and the breakfast plate is changing because of it.

The Myth That Held On Too Long

For most of the past half-century, dietary cholesterol and blood cholesterol were treated as the same problem, and eggs paid the price.

The Harvard Nutrition Source now notes that up to one egg per day is not associated with increased heart disease risk in healthy individuals, and that dietary cholesterol and blood cholesterol are only weakly related.

The 2025 confirmation came from a randomized crossover study published in the American Journal of Clinical Nutrition, which found that eating two eggs daily as part of a diet low in saturated fat actually reduced LDL cholesterol after five weeks.

What raises cholesterol, researchers now say, is not the egg. It is what most people pair it with.

What Eggs Do for Midlife Bodies

As women move through perimenopause, muscle mass begins to decline at a rate that most health guidelines underestimate. Experts now broadly agree that protein needs increase significantly at this stage of life, and eggs deliver six grams of complete, highly bioavailable protein each, making them one of the most efficient protein sources available.

Johns Hopkins Medicine specifically recommends eggs for women in perimenopause for muscle maintenance and bone health. A peer-reviewed 2025 review found that nutrients concentrated in eggs, including protein, choline, tryptophan, and vitamin D, may also support sleep quality and help regulate appetite during the menopausal transition.

The Brain Benefit Worth Knowing

Choline is a nutrient roughly 90% of Americans do not get enough of, and its shortage becomes more consequential with age.

It is essential for memory, the formation of neurotransmitters, and cognitive function, and two eggs deliver more than half the recommended daily intake in one sitting.

The yolks also contain lutein and zeaxanthin, two antioxidants that protect eye health and have been linked to better cognitive performance in older adults. Both nutrients are absorbed more efficiently from egg yolks than from plant sources, because the fat in the yolk helps carry them into the bloodstream.

What the Science Now Says

A 2025 University of South Australia study concluded that eggs are not the problem, and that saturated fat, the butter, bacon, and processed meats that often accompany them, is where the cardiovascular risk actually lives.

What is driving women back to eggs is not a trend. It is a combination of shifting science on cholesterol, a growing understanding of midlife protein needs, and a dawning recognition that the yolk, the part most discarded for decades, is where nearly all the nutrition actually lives.

Sometimes the thing that was unfairly blamed turns out to be exactly what the body needed all along.
