Micro-nutrient nutrition value of Brussels sprouts

Brussels sprouts contain many vitamins, minerals, and other health-promoting phytochemicals.

Above all, Brussels sprouts are rich in:

  • potassium, 389 mg, or 14% DV.
  • lutein + zeaxanthin, 1590 mcg.
  • beta-carotene, 450 mcg.
  • vitamin K, 177 mcg, or 150% DV.
  • vitamin C, 85 mg, or 113% DV.
  • iron, 1.4 mg, or 17% DV.

Health benefits of eating Brussels sprouts

Brussels sprouts belong to the cruciferous family.

Other cruciferous vegetables are broccoli, kale, arugula, collard greens, mustard greens, turnip greens, radishes, cauliflower, cabbage, etc.

What’s so important about these vegetables?

They contain a unique phytochemical. It’s called sulforaphane.

It’s exclusively present in cruciferous vegetables.

Also, many of the health benefits of eating Brussels sprouts come from the sulforaphane.

Good eyesight, vision, and eye health

Brussels sprouts can protect your eyesight.

Firstly they are rich in lutein and zeaxanthin (1590 mcg) and beta-carotene (450 mcg). Both are important for good vision.

According to the American Optometric Association (AOA), the retina of the eye contains lutein and zeaxanthin.

Lutein and zeaxanthin have many functions.

Firstly, they are powerful antioxidants, that fight free radicals. Free radicals can damage the retina of the eye.

Among others, lutein and zeaxanthin filter the harmful high-energy blue wavelengths of light. They have a key role in protecting the eyes.

So, lutein and zeaxanthin intake is important for eye health, especially because the human body can’t produce them.

Hence, we should consume them through food. The best source is green vegetables. 

Furthermore, the higher dietary intake of lutein, zeaxanthin and vitamin E was associated with a significantly decreased risk of cataract formation.

So, what’s the recommended lutein and zeaxanthin daily intake? There isn’t an official suggestion.

The American Optometric Association suggests consuming about 10 mg of lutein and 2 mg of zeaxanthin per day.

Other good sources of lutein, zeaxanthin, and beta-carotene are:

Lutein and Zeaxanthin (mg)beta-Carotene (mg)
turnip greens 12.8 6.9
spinach 12.2 5.6
kale 6.2 2.9
collard greens 4.3 3
green peas 2.5 0.5
Brussel sprouts 1.6 0.45
broccoli 1.4 0.4
corn 0.6 0.05
green beans 0.6 0.4
orange 0.1 0.07
Foods good for your eyes.

You can see the whole list of foods rich in lutein, zeaxanthin, and beta-carotene here.

Do you remember sulforaphane, the unique compound of cruciferous vegetables?

Scientists found that sulforaphane can protect the lens cells of the eye against oxidative stress (1).

Practically, eating sulforaphane-rich vegetables, such as Brussels sprouts, could potentially delay the development of cataract.

The health benefits of eating Brussels sprouts are so many…

Boosts your immune system

Brussels sprouts are especially rich in vitamin C. 100 gr contains 85 mg, or 113% DV.

Vitamin C is essential for good health. Furthermore, vitamin C is a powerful antioxidant, that contributes to immune defense and protects us against environmental oxidative stress (2).

Whenever you cook Brussels sprouts, sprinkle lemon juice and olive oil as a dressing, for additional health benefits.

Remember, citrus fruits, such as lemon, are rich in vitamin C. Furthermore, olive oil is a good source of polyphenols.

So, there is no need to take vitamin C supplements. There are so many foods rich in vitamin C.

Are Brussels sprouts good for weight loss?

Eating Brussels sprouts is beneficial for losing weight fast. Firstly, Brussels sprouts are rich in dietary fiber. High fiber intake has linked to weight loss. Secondly, Brussels sprouts are pretty low in calories. They have only 43 calories per 100g. Also, they’re a particularly filling food. Eat them regularly, as part of your healthy diet.

Certainly, eating lots of fruits and vegetables is good for losing weight fast. They’re low in calories and high in fiber.

Remember… Brussels sprouts are good for you for losing weight. They are high in fiber but low in calories.

Will Brussels sprouts make you poop?

Fiber is vital for healthy, solid bowel movements. It is known that diets low in fiber induce constipation.

As, Brussels sprouts are rich in fiber, they may help people with constipation.

Another common reason for chronic constipation is the inefficient water intake. Try to drink more water or other liquids, if you have constipation problems.

There are two main types of dietary fiber. Soluble and insoluble.

Brussels sprouts contain mainly soluble fiber. Soluble fiber is fermented in the gut, feeding beneficial gut bacteria.

On the other hand, insoluble fiber may help you more in preventing constipation. In fact, many foods contain insoluble fiber. For instance, whole grains, legumes, and many vegetables all are high in insoluble fiber. Some common foods high in fiber are potatoes, sweet potatoes, oatmealricespinachbroccolibananasapplescarrots, and avocados.

Consuming foods with fiber and water, such as pomegranates, mangos, oranges, or cucumbers is beneficial for treating constipation!

Are Brussels sprouts good for people with diabetes?

The carbohydrate amount of Brussels sprouts is ideal for diabetics.

100 gr contains only 2.2 grams of sugar.

Contrary, Brussels sprouts are high in fiber, meaning that they won’t spike the blood sugar.

Also, the Glycemic Index of Brussels sprouts is pretty low.

Furthermore, as Brussels sprouts have a low carbohydrate amount, they also have a particularly low Glycemic Load.

Antioxidants can help people with diabetes

Additionally, many vegetables are rich in antioxidants.

For instance, Brussels sprouts are rich in alpha-Lipoic Acid, or ALA.

The ALA is a powerful antioxidant. It fights chronic oxidative stress. Moreover, ALA can help people with diabetes, in many ways (4).

Other vegetables that are a good source of ALA are spinach, broccoli, tomato, garden peas, and rice bran.

Eating Brussels sprouts for fighting cancer

Do you remember sulforaphane? The unique compound of cruciferous vegetables?

It seems that it has chemopreventive properties as well. There is no wonder why scientists start to use it against cancer.

Researchers gave broccoli sprout extract, containing a high amount of sulforaphane, to women with breast cancer and men with prostate cancer. They didn’t observe any significant adverse effects (5).

Most noteworthy, sulforaphane effectively inhibited tumor growth.

Also, Brussels sprouts are high in fiber. It is known that adequate amounts of fiber can reduce the risk of certain cancers, such as colon cancer (6).

Moreover, Brussels sprouts are rich in antioxidants. Antioxidants fight free radicals and chronic oxidative stress. Both common in many types of cancer.

Eating Brussels sprouts against Alzheimer’s disease

Sulforaphane has also potent anti-inflammation and neuroprotective properties.

Researchers have found that it can prevent various brain diseases, such as (7):

  • stroke,
  • Alzheimer’s disease,
  • Parkinson’s disease,
  • traumatic brain injury,
  • autism spectrum disorders.

Helps fight nasal allergies naturally

The benefits of eating Brussels sprouts don’t stop…

It seems that sulforaphane can help suppress the nasal inflammatory response.

One reason that nasal inflammation occurs is the air pollution. Air pollution generates oxidative stress, causing nasal allergies and asthma.

Scientists gave people with nasal allergies or asthma, sulforaphane doses equivalent to the consumption of 100-200 grams of broccoli, with great results (8).

Sulforaphane is present in all cruciferous vegetables, including Brussels sprouts.

Helps people with autism

In a recent study, researchers showed that sulforaphane could significantly reduce the behavioral symptoms of autism (9).

Autism spectrum disorder seems to affect 1 in 68 children. The causes vary widely.

Its main characteristics are:

  • impaired social interaction,
  • impaired communication,
  • restricted or repetitive behaviors.

Although more research is needed, the effects of sulforaphane appeared clear and powerful to many caregivers. Moreover, caregivers sensed a reduction in symptom intensity.

Strong bones and osteoporosis.

Brussels sprouts can help with osteoporosis. Furthermore, Brussels sprouts can keep your bones strong.

Firstly, they are rich in vitamin K. Vitamin K has been linked to a good bone mineral density and decrease fracture risk (10).

Other foods rich in vitamin K, here.

Secondly, Brussels sprouts have calcium. Also, they are rich in dietary fiber.

Dietary fiber may increase calcium absorption. Also, may protect against bone loss at the hip in older men (12).

Do you want healthy bones? Eat more calcium-rich foods. Even fruits contain calcium. The whole list here.

Avoid cow’s milk. It seems that cow’s milk won’t protect your bones, despite its high calcium content.

Is it OK to eat Brussels sprouts every day?

The health benefits of eating Brussels sprouts are so many. But how often should you eat Brussels sprouts?

There are people who shouldn’t eat Brussels sprouts every day. Why?

Because Brussels sprouts are rich in vitamin K. 100 gr contains 177 mcg.

According to the American National Institutes of Health, men need about 120 mcg and women only 90 mcg of vitamin K per day.

So, a cup of Brussels sprouts can provide more than 195% DV (Daily Value). But, what’s the problem?

Vitamin K is a fat-soluble vitamin. It concentrates in body fat. But, the possibility of vitamin K toxicity is low.

Scientists haven’t found any side effects of excessive vitamin K consumption. Neither from food, nor supplements.

Side effects of everyday eating of Brussels sprouts

Unfortunately, vitamin K may interact with medication.

If you’re taking Warfarin (or other anticoagulants), antibiotics, bile acid sequestrants (reduce cholesterol), or orlistat (weight loss drug) on a regular basis should inform your doctor, if you regularly eat foods rich in vitamin K.

Besides Brussels sprouts, many other vegetables and spices are particularly rich in vitamin K. The whole list here.

Is broccoli or Brussels sprouts better for you?

Both broccoli and Brussels sprouts are cruciferous vegetables. So, both contain sulforaphane.

Additionally, both are rich in fiber, vitamins, minerals, and antioxidants. The health benefits of eating Brussels sprouts and broccoli are so many.

For instance, broccoli is rich in calcium, dietary fiber, vitamin C, vitamin K, and many more.

So, try to eat them both, along with all the other cruciferous vegetables (kale, arugula, cabbage, collard greens, mustard greens, turnip greens, etc).

How can eat Brussels sprouts?

Certainly, Brussels sprouts are cooked easily. So, they can easily be a part of a healthy whole food plant-based diet.

You can enjoy them in many ways: roasted, sautéed, boiled or baked.

What do Brussels sprouts taste like?

Cruciferous vegetables contain a sulfur-containing phytochemical called glucosinolate.

This compound is responsible for the distinctive odor and bitter flavor.

To get rid of this strong odor, fast cook Brussels sprouts. You’ll reduce this unique aroma of Brussels sprouts or broccoli.

For better results, add a few drops of vinegar in the water.

How to increase sulforaphane absorption?

Although, it isn’t an option for Brussels sprouts, prefer eating other cruciferous vegetables raw.

Scientists found that consumption of raw broccoli has better results, compared to cooked broccoli (11):

  • faster sulforaphane absorption,
  • higher sulforaphane bioavailability,
  • higher total amount of sulforaphane in the blood.

So, don’t cook cabbage. Better enjoy it in salads.
