Why Broccoli Sprouts Support Brain Health + How To Eat More Of Them

Perhaps the most powerful and studied component of broccoli is sulforaphane1—a sulfur-rich compound that reduces oxidative stress that can contribute to brain disease2. A full-grown head of broccoli does contain sulforaphane, but broccoli sprouts have 10 to 100 times more3!

On day three or four of growing broccoli, when the sprouts are one to two inches tall, is when the plant's sulforaphane content is highest. According to a report published in the Proceedings of the National Academy of Sciences4, just a small 1-ounce serving of broccoli sprouts provides 73 milligrams of sulforaphane glucosinolate.

During oxidative stress, large amounts of reactive oxygen species such as hydrogen peroxide (H₂O₂), hydroxyl radical, and superoxide anion are produced that damage DNA6. DNA damage leads to mutations that, in turn, are associated with diseases such as cancer and coronary heart disease, as well as inflammatory diseases such as arteriosclerosis and anxiety.

I wish every human being on the planet consumed chlorophyll—the green pigment in plants—on a daily basis. Chlorophyll is a compound found in dark leafy greens like kale, spinach, collard greens, dandelion greens, turnip greens, broccoli and broccoli sprouts, and blue-green algae, like chlorella and spirulina.

Although I feel that chlorophyll has been understudied, it has been shown to have many benefits for brain health specifically. For example, chlorophyll contains magnesium, which we know helps to reduce anxiety8.

This ultimate green salad is made from dark leafy greens, among the most powerful foods for reducing stress and anxiety. Built on a foundation of herbs, this salad is so simple yet really flavorful and refreshing.

Broccoli sprouts are a brain-boosting food that can help ease anxiety and support whole-body health. I love to eat them in salads and smoothies every few days for a quick hit of functional nutrition.
