Rhubarb, the tart and tangy vegetable commonly used in pies and jams, has long been a staple in many a gardener’s backyard. But is it more than just a sweet treat? In recent years, rhubarb has been touted as a superfood, packed with nutrients and antioxidants that can provide a range of health benefits. But what exactly makes rhubarb a superfood, and is the hype surrounding it justified?
The Nutritional Powerhouse of Rhubarb
Rhubarb is a nutrient-dense food, low in calories and rich in vitamins, minerals, and antioxidants. One cup of cooked rhubarb contains:

- Fiber, manganese, and magnesium, which support healthy digestion, bone health, and energy production
But what really sets rhubarb apart is its high antioxidant content. Antioxidants are compounds that help neutralize free radicals, unstable molecules that can cause damage to cells and contribute to chronic diseases like cancer, heart disease, and Alzheimer’s.

Rhubarb contains a range of antioxidants, including:
- Anthocyanins, powerful antioxidants responsible for the plant’s deep red color

One study published in the Journal of Agricultural and Food Chemistry found that rhubarb extract had higher antioxidant activity than many other fruits and vegetables, including strawberries, blueberries, and broccoli.

What makes rhubarb a superfood?
Rhubarb is considered a superfood due to its exceptional nutritional profile, which is packed with vitamins, minerals, and antioxidants. It is an excellent source of vitamin K, calcium, and fiber, making it an ideal ingredient for promoting digestive health and bone density. Rhubarb is also rich in antioxidants like anthocyanins and quercetin, which have been shown to have anti-inflammatory properties and protect against chronic diseases.
Furthermore, rhubarb contains a range of other essential nutrients, including vitamin C, potassium, and manganese. These nutrients work together to support immune function, maintain healthy blood pressure, and even support healthy skin and hair growth. With its unique combination of macro and micronutrients, rhubarb is an excellent addition to a balanced diet and has earned its reputation as a superfood.
How do I choose fresh rhubarb?
When selecting fresh rhubarb, look for stalks that are firm, crisp, and free of bruises or blemishes. The stalks should have a vibrant red or green color, depending on the variety, and should not be limp or wilted. Avoid stalks with yellow or brown leaves, as they may be past their prime. Fresh rhubarb should have a slightly tart or sour smell, and the stalks should be heavy for their size.
It’s also important to note that rhubarb is typically available in the spring and early summer, when it’s at its peak freshness. During this time, the stalks will be more tender and have a more delicate flavor. If you’re purchasing rhubarb from a supermarket, make sure to store it in the refrigerator to keep it fresh for up to a week. If you’re growing your own rhubarb, harvest the stalks when they’re between 12 and 18 inches long, and trim the leaves to encourage new growth.
Can I eat rhubarb raw?
While rhubarb is often cooked or baked into sweet treats, it can be eaten raw in moderation. However, it’s essential to note that raw rhubarb contains high levels of oxalic acid, which can be toxic in large quantities. Oxalic acid can cause symptoms like nausea, vomiting, and kidney damage if consumed excessively.
If you do choose to eat rhubarb raw, make sure to only consume small amounts, such as adding it to salads or using it as a garnish. It’s also recommended to balance the tartness of the rhubarb with sweet ingredients, like honey or fruit, to reduce the risk of oxalic acid toxicity. Cooking or baking rhubarb can help break down the oxalic acid, making it safer to consume in larger quantities.
How do I prepare rhubarb for cooking?
Before cooking with rhubarb, it’s essential to remove the leaves, as they contain high levels of oxalic acid and are toxic. Simply trim the leaves from the stalks, and discard them. Then, wash the stalks in cold water to remove any dirt or debris.
To prepare rhubarb for cooking, you can either chop or slice the stalks into desired lengths. For most recipes, you’ll want to cut the rhubarb into 1-2 inch pieces. You can also peel the stalks if they’re particularly thick or fibrous. To bring out the natural sweetness of the rhubarb, you can soak the chopped pieces in cold water for about 30 minutes before cooking.
What are some creative ways to use rhubarb?
Rhubarb is an incredibly versatile ingredient that can be used in a range of sweet and savory dishes. One creative way to use rhubarb is to add it to savory dishes, like stir-fries or braises, where its tartness can add depth and complexity to the flavors. You can also use rhubarb to make tangy sauces and marinades for meats or vegetables.
For sweet treats, try using rhubarb in place of strawberries or blueberries in desserts like crumbles, crisps, or pies. Rhubarb pairs particularly well with sweet ingredients like honey, maple syrup, or citrus, and can be used to make delicious jams, preserves, or ice cream. You can even use rhubarb to make refreshing drinks, like rhubarb tea or rhubarb-infused water.
Can I grow my own rhubarb?
Growing your own rhubarb is a great way to have a steady supply of this superfood right in your own backyard. Rhubarb is a hardy perennial that prefers well-drained soil and full sun to partial shade. To grow rhubarb, start by purchasing a crown or seedling from a nursery or gardening store.
Plant the crown or seedling in the early spring or fall, when the weather is cooler, and water regularly to keep the soil moist. Rhubarb requires minimal maintenance, aside from occasional watering and fertilization. Be sure to harvest the stalks in the spring, when they’re at their most tender, and trim the leaves to encourage new growth. With proper care, your rhubarb plant can produce delicious stalks for years to come.
Is rhubarb safe for people with dietary restrictions?
Rhubarb is a great option for people with dietary restrictions, as it’s naturally gluten-free, vegan, and low in calories. However, individuals with kidney stones or gout should consume rhubarb in moderation, as it’s high in oxalates, which can exacerbate these conditions.
Additionally, people with sensitivity to oxalic acid or those taking certain medications, like blood thinners, should consult with their healthcare provider before consuming rhubarb. Pregnant or breastfeeding women should also talk to their healthcare provider about safe rhubarb consumption, as high levels of oxalic acid may affect fetal development or milk production. Overall, rhubarb can be a nutritious and delicious addition to a balanced diet, but it’s essential to consume it in moderation and with awareness of individual needs.
