Onions are an underappreciated nutrition superhero. Here are five great reasons to eat more of them.

1. Onions have an exceptionally high total polyphenol content. Polyphenols are a family of potent plant antioxidants that offer broad-spectrum disease protection.
2. Onions are uniquely high in quercetin. Quercetin is one of the most potent anti-inflammatory, and thus disease-fighting compounds found in Mother Nature’s apothecary.
3. Onions are a standout veggie for cancer-protection, particularly for colorectal, throat, and ovarian cancer.
4. Onions contain an abundance of inulin fiber, which feeds the good bacteria in our guts.
5. Onions are almost calorie free, yet revered for their flavor-enhancing culinary characteristics.

The bottom line: Include them regularly in your diet – raw or cooked for a blast of flavor and health.
