A Harvard nutritionist and a neuroscientist agree this is the No. 1 food for a healthy brain

Across the board, experts agree that eating leafy greens is essential for overall health, especially for your brain.

Some of the green leafy vegetables that you can add to your meals are:

• Kale
• Spinach
• Lettuces
• Cabbage
• Swiss chard
• Bok choy
• Mustard greens

1. They’re rich in B vitamins

Often, conditions like depression and dementia are associated with a vitamin B deficiency, according to a study from the Wayne State University School of Medicine.

Green leafy vegetables are a wonderful source of vitamin B9, Naidoo told CNBC Make It in 2022. The vitamin, also known as folate, is “a key vitamin for supporting brain and neurological health, optimal neurotransmitter function, and balanced psychological health,” she added.

Leafy greens are the first type of food that Naidoo suggests for her patients who are looking to boost their mood.

2. They’re high in brain-boosting nutrients

Green leafy vegetables are also full of what Genova calls “brain-boosting nutrients” including folate, lutein and beta-carotene.

Lutein has been linked to an improvement in brain function and brain structure for older adults. And a systematic review found that taking beta-carotene supplements can boost “verbal and cognitive memory.”

3. They’re full of fiber

Increasing intake of dietary fiber was associated with a lower chance of developing depression, a study published in “Complementary Therapies in Medicine” in 2021 found.

Naidoo prefers to recommend getting more fiber through your diet, specifically plant-based foods. And leafy greens just so happen to be fiber-dense.
