The Vibrant World of Beets
Beets, or beetroot, are a popular root vegetable known for their earthy flavor and rich nutrient profile. They come in several varieties distinguished by their color, including the familiar deep red, the less common golden or yellow, and the striking striped Chioggia. These vibrant hues are not just for aesthetics; they are caused by unique plant pigments called betalains, which are also responsible for many of beets' powerful health benefits. A lesser-known variety, the white beet or sugar beet, lacks these colorful betalains and offers fewer antioxidant benefits compared to its colorful counterparts. By understanding the specific compounds in each type, you can make informed decisions to maximize your nutritional intake.
The Power of Betalains: Antioxidants by Color
The key nutritional difference between red and golden beets lies in the type of betalain they contain. Betalains are a class of antioxidants with strong anti-inflammatory properties, and they are divided into two main groups:
- Betacyanins (Red-Violet): Found primarily in red and purple beets, these pigments are responsible for the vegetable's distinctive deep color. They are particularly noted for their potent antioxidant and anti-inflammatory capabilities. Some studies suggest that betacyanins may have a slightly stronger antioxidant effect.
- Betaxanthins (Yellow-Orange): Golden beets contain these yellow to orange pigments. While different in structure from betacyanins, they also provide powerful antioxidant and anti-inflammatory effects.
Comparing Beet Varieties: A Nutritional Breakdown
While the antioxidant types vary, the overall nutrient profiles of red and golden beets are remarkably similar. Both are excellent sources of nitrates, which the body converts to nitric oxide to improve blood flow and lower blood pressure. The primary difference often comes down to taste and how the pigments interact with other foods.
| Feature | Red Beets | Golden Beets |
|---|---|---|
| Antioxidant Type | High in betacyanins (red-violet pigments). | High in betaxanthins (yellow-orange pigments). |
| Antioxidant Potency | Contains betacyanins with strong antioxidant properties, possibly slightly more potent. | Potent antioxidants and anti-inflammatory agents, similar to red beets overall. |
| Flavor Profile | Characterized by a more robust, earthy flavor. | Sweeter and milder in flavor, with less earthiness. |
| Staining | High levels of betacyanins can stain hands and urine (a harmless condition known as beeturia). | Contains no red pigment, so it won't stain hands or other foods. |
| Best For | Dishes where the bold color is desired, such as borscht or juices. | Salads, golden hummus, or when a milder flavor is preferred. |
Beyond the Root: The Power of Beet Greens
When considering beet nutrition, it's a mistake to overlook the greens. These leafy tops are not only edible but are packed with nutrients. Like other dark, leafy greens, beet greens are high in:
- Carotenoids: Including beta-carotene, lutein, and zeaxanthin, which are crucial for eye health and vision.
- Nitrates: Contributing to the same blood-flow benefits as the root.
- Minerals: They contain significantly higher levels of iron, potassium, and vitamin A than the root.
Beet greens can be cooked like spinach or Swiss chard and added to salads, sautés, and soups.
How to Get the Most Out of Your Beets
Incorporating beets into your diet is a simple and effective way to boost your nutrient intake. While they are a versatile vegetable, preparation method can affect their nutritional value.
- Eat them raw: Grating raw beets into salads or slaws retains the maximum amount of vitamins and antioxidants, as these are sensitive to heat.
- Roast them: Roasting brings out the natural sweetness of beets and is a delicious way to enjoy them. While some nutrients may be lost, roasting still preserves most of the betalains.
- Juice them: Beetroot juice is a popular way to get a concentrated dose of nutrients, especially nitrates, for athletic performance. A systematic review found that beetroot juice supplementation enhances cardiorespiratory endurance in athletes. However, juicing removes fiber, and excessive intake can be high in sugar.
- Steam or Boil: Steaming or boiling beets can lead to some nutrient leaching into the water, but it's a quick and easy preparation method. Steaming retains more nutrients than boiling.
What Does Science Say?
Both red and golden beets are rich in nitrates, which have been widely studied for their cardiovascular benefits. The body converts dietary nitrates into nitric oxide, a molecule that signals blood vessels to relax and widen, leading to lower blood pressure and improved blood flow. This vasodilation effect is why beets are often touted for their ability to enhance athletic performance by increasing oxygen delivery to muscles. Research has explored the potential of beetroot supplementation for various health outcomes, highlighting the importance of the nitrate content common to the vibrant varieties.

Conclusion: So, Which Color Beet Wins?
When it comes to the question of what color beets are the healthiest, the answer is that all colorful varieties are excellent for your health. While red beets may contain betacyanins with a slightly stronger antioxidant profile, golden beets offer equally valuable betalains with a milder, sweeter flavor. The key takeaway is to incorporate a variety of colorful beets into your diet, including their nutritious greens, to benefit from the full spectrum of their health-boosting compounds. White sugar beets, by contrast, lack the beneficial betalain pigments and are not a comparable nutritional choice. Whether you prefer the earthy taste of red beets or the sweeter notes of golden beets, you can be confident you are making a healthy choice. Ultimately, the healthiest beet is the one you enjoy eating, adding color and nutrients to your plate.
