Targeted brain nutrients are the foundation of the Lifestyle Pillars for Memory  that can help fuel your body to prevent cognitive decline. When we feed our bodies with targeted brain nutrients, it can help reduce stress, provide better sleep and help build brain health. These four foods are packed with the nutrients you need to aid in cognitive function:


You’ll hear many people talk about the antioxidants in blueberries, and they are onto something – nutrients in blueberries called polyphenols can have a range of benefits in addition to their antioxidant properties. These polyphenols contribute to overall health as well as vascular and gastrointestinal health. Most importantly, consuming the polyphenols in blueberries is associated with decreased risk of dementia because of their anti-inflammatory and antioxidant properties. Blueberries can even enhance your current cognitive function by improving executive function and memory.


Turmeric has been found to have incredible neuroprotective qualities in helping protect our brain. Turmeric, like blueberries, has an antioxidant effect, and it can also inhibit inflammation in the body and neuroinflammation in the brain. Turmeric can be added as a flavoring to many foods. You can add it to soups, smoothies and teas; toss it with vegetables and greens; or add a pinch to your scrambled eggs. Turmeric most effectively stabilizes or prevents cognitive decline, as opposed to improving it, but it is still a valuable tool to help tackle cognitive impairment.

Kale, Swiss chard, and Other Leafy Greens

Leafy greens are important to any nutritious diet, but they can protect your brain too. In a recentstudy, scientists found that eating leafy greens can make you 11 years younger in cognitive age. In the same study, it was discovered that a nutrient called folate decreased certain protein levels that are associated with Alzheimer’s. Other compounds in leafy greens like vitamin K and lutein (also found in egg yolks) all help to slow cognitive decline.


Scientists have found that people who eat legumes display better cognitive performance. The amino acid combination in legumes is what makes them unique: Amino acids in legumes have been shown to improve insulin sensitivity, which may improve cognitive performance as well. Particularly for the elderly, legumes and their amino acids could help prevent dementia, so include chickpeas and black beans in your next meal to reap some important benefits.
