The #1 Healthy Fat Doctors Want Midlife Women to Eat More Of

For decades, women were told to cut the fat. Low-fat this, fat-free that, and somehow the advice always came with a side of guilt. But there is one fat that doctors are now actively urging midlife women to eat more of, not less.

And chances are, most women are not getting nearly enough of it.

The Fat That Changes Everything in Midlife

The healthy fat getting all the attention right now is omega-3 fatty acids, specifically the forms known as EPA and DHA. Nearly 95% of Americans are not getting enough of them, but for women moving through perimenopause, the stakes are particularly high.

When estrogen levels begin to drop, the body loses one of its most powerful natural protectors. Estrogen keeps blood vessels flexible and helps regulate cholesterol, so when it declines, heart disease risk climbs.

What Omega-3s Actually Do for Your Body

Omega-3s help counteract the cardiovascular changes triggered by falling estrogen by lowering triglycerides, reducing blood pressure, and supporting healthy cholesterol levels. Studies show women who consume more omega-3s regularly tend to have better cholesterol numbers and circulation overall.

But the heart is only part of the story. Research published in 2025 found that increasing EPA and DHA intake is associated with improved brain function during the menopausal transition, offering potential relief from brain fog, mood shifts, and memory dips that so many women experience and rarely talk about.

The Brain Fog Connection

Around 60% of midlife women report difficulty concentrating during this hormonal window. Omega-3s support the structural integrity of brain cell membranes and help regulate the pathways tied to mood and mental clarity.

Some research has even suggested they may reduce the frequency of hot flashes, making them one of the few nutritional tools that address both physical and cognitive symptoms at once.

The Best Food Sources to Know

Fatty fish are by far the most effective source of EPA and DHA, with just three ounces of salmon delivering close to 2,000 milligrams. Sardines and mackerel are even more concentrated options and tend to be more affordable.

For women who do not eat fish, flaxseeds, chia seeds, and walnuts provide a plant-based omega-3 called ALA, though the body converts it to EPA and DHA less efficiently.

The good news is that adding omega-3s does not require a dramatic overhaul of how you eat. Two servings of oily fish a week, a handful of walnuts, or a sprinkle of chia seeds over yogurt in the morning is often all it takes to start making a difference.
