5 Morning Foods Dietitians Say May Support Brain Health

Starting the day with a nourishing breakfast can help set the stage for better focus, but some foods do more for memory and concentration than others.

"After an overnight fast, the brain is essentially relying on that first meal to set the tone," Wendy Bazilian, DrPh, RD, nutritionist, author, and host of the podcast 1,000 Waking Minutes, told HEALTH. While some options, such as ultra-processed foods or high-sugar breakfasts, have been associated with poorer mental health outcomes, others provide nutrients that may help keep you sharp through the morning and beyond.

1. Walnuts

A small recent study found that adults ages 18 to 30 who ate a walnut-rich breakfast had quicker reaction times and stronger memory performance over the course of the day than those who ate a breakfast without nuts.

"This is meaningful because it suggests that including walnuts at breakfast may have measurable short-term cognitive effects in healthy young adults," Bazilian said.

Bazilian recommends adding a handful to oatmeal, yogurt, or even a savory grain bowl.

2. Blueberries

"Blueberries may be a smart morning memory morsel for all ages," Maggie Moon, MS, RD, author of The MIND Diet: 2nd Edition, told HEALTH.

Research has linked blueberries to better cognition. A systematic review of 13 studies found that children’s same-day memory recall improved for up to six hours after eating blueberries.

Another review found that older adults with mild cognitive impairment and subjective cognitive decline who regularly ate blueberries saw notable gains in episodic memory.

3. Eggs

Eggs, a breakfast staple for many people, are a strong source of choline, an essential nutrient for the brain. "Choline […] plays a direct role in brain function, including the production of acetylcholine, a neurotransmitter involved in memory and learning," Bazilian said.

In a randomized controlled trial, adults who consumed about 300 milligrams per day of egg-derived choline for 12 weeks improved their verbal memory. A separate systematic review concluded that eating about one egg a day may help support memory, verbal fluency, and processing speed.

"Several studies have shown that nutrients found in eggs may benefit neurodevelopment starting from our very first days through early adulthood, including DHA, choline, lutein, as well as protein and a range of vitamins and minerals," Moon said.

4. Mushrooms

"A great reason to start the day with mushrooms is that they’ve been shown to stabilize mood and reduce mental fatigue for up to six hours, suggesting that fighting the afternoon mental slump may start in the morning," Moon said. A small study found these effects after participants ate the equivalent of about 1 cup of fresh mushrooms.

Mushrooms may also support cognition over the long term. In one study that tracked people for 18 years, those who ate more mushrooms performed better on cognitive tests than those who ate fewer. "It appears to be dose-dependent, which is to say, the more mushrooms, the better," Moon said.

Try sautéing mushrooms in olive oil, folding them into a scramble or omelet, layering them on toast with Greek yogurt or cottage cheese, or adding them to breakfast porridge.

5. Avocado

Avocados provide lutein, an antioxidant linked to brain health.

Higher lutein levels have been associated with better cognitive performance, including memory and problem-solving. In one randomized controlled trial, older adults who ate one avocado per day for six months had higher lutein levels, along with improvements in working memory, problem-solving efficiency, and sustained attention.

Bazilian added that avocados also offer monounsaturated fats and fiber, which can support blood flow and help keep blood sugar steadier. "Supporting circulation and steady energy are two of the more immediate ways nutrition shows up in how we think and feel," she said.
