Nourishing Your Brain: 5 Essential Foods for Cognitive Health
Written on
Chapter 1: Introduction to Brain Health
Maintaining good health involves more than just consuming fruits, vegetables, and whole grains, although that advice is well-founded. Surprisingly, only about 10% of people meet the recommended intake of fruits and vegetables. However, there are other crucial foods that can significantly contribute to our health.
Neuroscientist Dr. Lisa Mosconi, author of "Brain Food: The Surprising Science of Eating for Cognitive Power" and "The XX Brain: The Groundbreaking Science Empowering Women to Maximize Cognitive Health and Prevent Alzheimer’s Disease," highlights five specific foods that can enhance cognitive function.
Section 1.1: The Power of Soybeans
Soybeans are an excellent source of fiber, providing around 20.6 grams per cup when cooked. The recommended daily intake is about 25 grams for women and 38 grams for men, yet many people do not consume enough.
“Essentially, we need to prioritize fiber intake,” Mosconi emphasizes in "The XX Brain." “Incorporate fiber-rich foods to ensure optimal functioning of your brain, body, and hormones.”
Research from the University of Illinois indicates that fiber can help mitigate inflammation in the brain as we age. Rodney Johnson, a co-author of the study, stated, “Diet matters significantly. Many older adults consume 40% less fiber than the recommended levels, which could adversely affect brain health and inflammation.”
How to incorporate more soybeans:
You can enjoy young, green soybeans (edamame) steamed and served directly from the pods. They are also a great addition to soups, salads, and stir-fries. Just be cautious with processed soybean products like tofu and soy milk, as they often contain less fiber.

Section 1.2: Harnessing the Benefits of Herbs and Spices
Certain herbs and spices are rich in antioxidants, which combat free radicals—harmful byproducts of metabolism that can damage brain cells. Mosconi recommends incorporating cinnamon, cloves, oregano, peppermint, and rosemary into your diet.
“Our brain imaging studies suggest that diets abundant in these antioxidants correlate with stable brain energy levels and a reduced presence of Alzheimer’s plaques, particularly in women,” writes Mosconi in "The XX Brain."
While studying herbs and spices can be complex due to their small consumption amounts, research published in the International Journal of Molecular Sciences suggests a connection between these foods and protection against neurodegenerative diseases.
How to add more herbs and spices:
Sprinkle cinnamon and cloves on your morning oatmeal, brew peppermint tea, or enhance soups and salads with oregano and rosemary.

Section 2.1: The Importance of Fatty Fish
Fatty fish are a fantastic source of omega-3 fatty acids, known for their anti-inflammatory properties. Major diseases, including Alzheimer's and depression, have been linked to inflammation. Mosconi points to salmon, mackerel, herring, and sardines as excellent sources of omega-3s, advising limited consumption of larger fish like tuna due to mercury content.
“Regular fish intake is vital for brain health,” Mosconi states in "The XX Brain." “Individuals in middle age and older who eat fish once or twice weekly can lower their Alzheimer's risk by up to 70%.”
Studies involving over 3,500 participants support the idea that omega-3 fatty acids can safeguard against neurodegeneration in older adults, with calls for more research in younger populations.
How to include more fatty fish:
Canned albacore tuna makes a convenient option. Try it in a healthy salad or opt for salmon topped with pesto. Lake trout fillets are another easy-to-cook choice.
Section 2.2: Garlic and Onions for Gut Health
Garlic and onions serve as prebiotics, promoting the growth of beneficial gut bacteria. Other prebiotic-rich foods include asparagus, bananas, and legumes.
“Emerging research indicates our microbiome plays a role in various aspects of brain health and behavior, particularly in response to stress and anxiety,” Mosconi elaborates in "The XX Brain."
Research from the University of Colorado at Boulder shows that prebiotics can nourish beneficial gut bacteria and induce brain-affecting changes, potentially improving sleep.
How to incorporate more garlic and onions:
These ingredients are versatile additions to meals. Roast garlic and spread it on whole-grain crackers, or caramelize onions to enhance dishes or pizzas. They are also affordable pantry staples.
Section 2.3: The Role of Yogurt in Cognitive Health
Fermented foods, often referred to as probiotics, introduce beneficial bacteria into our digestive systems. While yogurt is a great source, Mosconi emphasizes the importance of choosing the right type.
“Opt for plain, full-fat, probiotic-rich yogurt,” she advises in "The XX Brain." “Yogurts with added sugars can encourage harmful bacteria growth instead of the beneficial kind.”
Research published in the Journal of Translational Medicine confirms that increasing probiotic-rich foods can enhance the population of good gut bacteria.
How to eat more yogurt:
Yogurt can be a nutritious breakfast when combined with fresh fruit and nuts. Alternatively, try a savory version by incorporating vegetables or add a layer of yogurt to your avocado toast.
The Bottom Line
For many, the first step toward a healthier diet is increasing vegetable intake. However, additional actions can be taken to nourish the brain. Incorporating soybeans, herbs and spices, fatty fish, garlic, onions, and yogurt into your meals can significantly benefit cognitive health.
