Brussels sprouts, once relegated to the realm of unappetizing childhood memories, have experienced a remarkable resurgence in popularity. No longer just a boiled, sulfurous side dish, they are now celebrated by food enthusiasts and chefs alike. This article explores the nutritional powerhouse that is the Brussels sprout and how it seamlessly integrates into the heart-healthy Mediterranean diet.
Understanding Brussels Sprouts
Brussels sprouts (Brassica oleracea, var. gemmifera) are small, leafy green vegetables resembling miniature cabbages. Believed to have originated in the Mediterranean region, they gained widespread cultivation in Belgium during the 16th century, eventually spreading throughout Europe and to North America. As a cruciferous vegetable, Brussels sprouts belong to the same family as kale, broccoli, cabbage, cauliflower, and arugula. This classification is significant because cruciferous vegetables are known for their impressive health benefits.
Nutritional Powerhouse
Brussels sprouts pack a significant nutritional punch, offering a wealth of vitamins, minerals, and antioxidants while remaining low in calories. One cup of raw Brussels sprouts (approximately 88 grams) provides:
- 37.8 calories
- 0.264 g of fat
- 7.88 g of carbohydrate
- 2.97 g of protein
They are an excellent source of vitamin C and vitamin K, meeting the National Institutes of Health’s (NIH) recommended daily requirements for these essential nutrients. Brussels sprouts also contain dietary fiber, folate, and provitamin A in the form of beta-carotene.

Bone Health
Brussels sprouts are a significant source of vitamin K-1, which plays a crucial role in bone formation and mineralization. Adequate vitamin K intake is linked to a lower risk of bone fractures. Vitamin K activates proteins necessary for bone formation.
Diabetes Management
Brussels sprouts contain alpha-lipoic acid (ALA), an antioxidant that has demonstrated the ability to lower glucose levels, increase insulin sensitivity, and prevent oxidative stress-induced changes in people with diabetes.
Cancer Prevention
Cruciferous vegetables like Brussels sprouts contain sulfur-containing compounds that break down into active compounds during consumption and digestion. These compounds may prevent cancer from developing in some organs. Brussels sprouts also contain a high amount of chlorophyll, which may act as an antioxidant against compounds responsible for the development of pancreatic cancer.
Vision and Skin Health
The vitamin C content of Brussels sprouts may help preserve eye health and reduce the risk of cataracts. Vitamin C also protects skin cells against sun damage and pollution, combats free radical damage, and supports collagen production, which improves skin strength and elasticity. Beta-carotene, a form of provitamin A, is also present in Brussels sprouts and is crucial for healthy skin.
Digestive Health
Brussels sprouts are high in fiber, which promotes digestive health by feeding beneficial gut bacteria. Certain beneficial microbes can convert fiber to short-chain fatty acids, which reduce inflammation in the gut.

Cardiovascular Health
Brussels sprouts’ antioxidant content may also protect the heart by reducing chronic inflammation. Kaempferol, a flavonoid found in Brussels sprouts, is linked to reduced cardiovascular inflammation and protection against heart disease.
Brain Health
Scientific studies have shown that the glucosinolates (a natural compound) in Brussels sprouts support brain health, helping to protect against brain diseases. Researchers say this is because the glucosinolates help protect against inflammation, which can lead to chronic diseases and tumor growth.
The Mediterranean Diet: A Foundation for Health
The Mediterranean diet is based on the traditional foods of countries bordering the Mediterranean Sea, including France, Spain, Greece, and Italy. This dietary pattern emphasizes whole foods while limiting processed foods. The Mediterranean diet generally involves eating whole foods, such as fruits and vegetables, whole grains, and lean protein, while limiting processed foods.
Core Principles of the Mediterranean Diet
- Abundant Plant Foods: The diet is rich in fruits, vegetables, whole grains, legumes, nuts, and seeds.
- Healthy Fats: Extra virgin olive oil is the primary source of fat, along with avocados and nuts.
- Lean Protein: Fish and seafood are consumed at least twice a week, with moderate amounts of poultry, eggs, and dairy.
- Limited Red Meat and Processed Foods: Red meat is consumed sparingly, and processed foods, added sugars, and refined grains are minimized.
Benefits of the Mediterranean Diet
Research has consistently demonstrated the numerous health benefits of the Mediterranean diet.
- Weight Management: Rich in fruits, vegetables, whole grains, and heart-healthy fats, the Mediterranean diet may help manage your weight.
- Cardiovascular Health: Helps prevent heart attacks and stroke.
- Diabetes Prevention: Helps prevent type 2 diabetes.
- Reduced Risk of Premature Death: For this reason, the Mediterranean diet is a suitable option for those looking to improve their health and protect against chronic disease.
- Anti-Inflammatory Effects: In a 2018 study, researchers found that not following the Mediterranean diet, or not following it consistently, was associated with higher markers of inflammation in the blood.
Integrating Brussels Sprouts into the Mediterranean Diet
Brussels sprouts fit perfectly into the Mediterranean diet due to their nutritional value and versatility. They align with the diet's emphasis on plant-based foods and can be prepared in various ways using Mediterranean flavors and techniques.

Tips for Buying and Preparing Brussels Sprouts
- Freshness: Look for Brussels sprouts that are firm, compact, and bright green. Avoid those with yellowing or wilting leaves.
- Size: Smaller sprouts tend to be sweeter and more tender than larger ones.
- Storage: Store Brussels sprouts in a bag in the refrigerator.
- Preparation: Rinse Brussels sprouts under cool running water, cut off the tough stem ends, and remove any wilted or damaged leaves.
- Cooking: Avoid overcooking Brussels sprouts, as this can result in a mushy texture and a sulfurous smell. Roasting, sautéing, grilling, or stir-frying are excellent cooking methods.
Potential Health Risks
While Brussels sprouts offer numerous health benefits, there are a few potential health risks to consider.
- Blood Thinners: Individuals taking blood-thinners, such as warfarin, should maintain a consistent amount of vitamin K intake each day due to its role in blood clotting.
- Digestive Issues: Eating large amounts of Brussels sprouts, especially if you are not used to a high-fiber diet, may cause gas, bloating, or digestive discomfort. It is best to gradually increase your intake of Brussels sprouts and other high-fiber foods.
