• Vitamins: Vitamin C (147 mg, 163% DV) and Vitamin K (177 μg, 148% DV)
• Minerals: Potassium, manganese, and folate
• Antioxidants: Kaempferol and glucosinolates, which reduce oxidative stress and inflammation

Brussels sprouts rank among the top 20 most nutrient-dense vegetables, with an ANDI score of 490 out of 1000 (University of California Davis Nutrition Department, 2023).

Health Benefits of Brussels Sprouts

1. Digestive Health: The fiber in Brussels sprouts supports gut microbiome health, promotes regular bowel movements, and reduces the risk of colorectal cancer by 27% (Harvard School of Public Health).
2. Anti-Inflammatory Properties: Antioxidants like kaempferol and glucosinolates help lower inflammation, reducing the risk of chronic diseases and certain cancers.
3. Immune Support: High Vitamin C levels boost white blood cell production and immunity.
4. Heart Health: Recent studies from the American Heart Association highlight that Brussels sprouts support heart health through multiple mechanisms. Potassium and folate help regulate blood pressure and reduce cardiovascular risks.
5. Weight Management: With a low caloric density, high satiety index, and significant fiber content, Brussels sprouts support healthy weight management.
6. Cancer Prevention: Glucosinolates and isothiocyanates found in Brussels sprouts are studied for their potential to prevent certain types of cancer. Studies indicate that consuming Brussels sprouts 2-3 times weekly can decrease cancer risk by up to 32%. The antioxidant kaempferol, abundant in these vegetables, is crucial in reducing oxidative stress and inflammation.

Potential Downsides

• Digestive Issues: Overconsumption can cause bloating and gas due to raffinose, a complex sugar.
• Allergies: Rare cases of sensitivity to cruciferous vegetables have been reported.

The History and Origins of Brussels Sprouts

Brussels sprouts trace their roots to Ancient Rome, where similar vegetables were cultivated. However, modern Brussels sprouts originated in Belgium during the 13th century, gaining their name from the Brussels region. By the 16th century, they spread across Europe and later to the Americas. Archaeological evidence from Belgium’s University of Ghent confirms their long-standing cultural significance.

Ingredients:

• 1 pound Brussels sprouts
• 2 tablespoons olive oil
• 1 teaspoon sea salt
• ½ teaspoon freshly ground black pepper
• Optional: Garlic powder, smoked paprika, or red pepper flakes for extra flavor

Preparation:

1. Select Fresh Brussels Sprouts:
   • Choose sprouts that are firm, bright green, and free of blemishes.
   • Smaller sprouts are typically sweeter and more tender, while larger ones may have a stronger flavor.
2. Trim and Prepare:
   • Rinse the Brussels sprouts thoroughly under cold water to remove any dirt or debris.
   • Trim the stem ends and peel away any yellow or damaged outer leaves.
   • Slice them in half lengthwise for even cooking if the sprouts are large, quarter them for better results.
3. Preheat the Oven:
   • Set your oven to 400°F (200°C). A hot oven is essential for achieving a crispy, caramelized exterior.
4. Season the Sprouts:
   • Toss the Brussels sprouts with olive oil, salt, and pepper in a large mixing bowl.
   • Make sure each piece is evenly coated with the oil for optimal roasting.

Roasting Process:

1. Spread Evenly on a Baking Sheet:
   • Arrange the Brussels sprouts cut side down on a large baking sheet. Avoid overcrowding, as this will cause them to steam instead of roast.
   • Use parchment paper or a nonstick baking sheet for easier cleanup.
2. Roast in the Oven:
   • Place the baking sheet in the oven’s center and roast for 20-25 minutes.
   • Halfway through cooking, stir or flip the sprouts to ensure even browning.
3. Check for Doneness:
   • The sprouts are ready when golden brown and tender when pierced with a fork. The outer leaves should be crispy and caramelized.

Optional Additions and Variations:

• Parmesan Cheese: Sprinkle-grated Parmesan over the sprouts during the last 5 minutes of roasting.
• Balsamic Glaze: Drizzle balsamic reduction or glaze over the finished sprouts for a tangy-sweet finish.
• Bacon: Add chopped, pre-cooked bacon to the baking sheet before roasting for extra flavor.
• Herbs: Toss with fresh thyme, rosemary, or parsley after roasting for an herbal boost.

Serving Suggestions:

• Side Dish: Serve alongside roasted chicken, grilled salmon, or steak.
• Salad Topping: Add roasted sprouts to a mixed greens salad with dried cranberries and goat cheese.
• Bowl Component: Pair with quinoa, roasted sweet potatoes, and avocado for a hearty grain bowl.

Tips for Perfectly Roasted Brussels Sprouts:

• Don’t Overcrowd the Pan: Ensure the sprouts are in a single layer and spaced apart.
• Use High Heat: A temperature of 400°F or higher is necessary to achieve caramelization.
• Experiment with Flavors: Add honey, maple syrup, or chili flakes for a creative twist.
