Five health benefits of Brussels sprouts

Brussels sprouts are incredibly nutritious. They’re rich sources of vitamins C, K, and folate and contain impressive amounts of health-promoting polyphenols and antioxidants.

Research suggests that regularly eating Brussels sprouts can lower the risk of cancer and heart disease, supports liver health and detoxification, and may help you shed some weight.

Here are five reasons why you should eat Brussels sprouts regularly!

1. Support digestion

Brussels sprouts are high in fiber, which can help to improve digestion and prevent constipation. Fiber also fuels the beneficial bacteria in your gut which support immune function and lower the risk of colon cancer.

Brussels sprouts contain polyphenols, plant chemicals with potent antioxidant and anti-inflammatory properties

3. Improve heart health 

Brussels sprouts are high in antioxidants, including vitamin C and flavonoids, which help to keep your blood vessels healthy and may protect against heart disease.

4. Support detoxification 

Research confirms that cruciferous vegetables, including Brussels sprouts, contain phytochemicals that stimulate the production of detoxification enzymes which help to bind drugs, waste, and other harmful compounds, making it easier to excrete these toxins.   

5. Help weight loss

Brussels sprouts are low in calories and high in fiber, making them a good choice if you are trying to lose weight. Fiber helps you feel full and satisfied, preventing snacking and overeating.

Typically, oven-roasted Brussels sprouts take 20 to 30 minutes. Larger sprouts can take a little longer, so adjust your cooking time if needed. 

To help your Brussels sprouts cook evenly, avoid overcrowding the sheet pan and roast them on the middle rack of your oven. It doesn’t matter if your sprouts face cut sides up or down.
