What is Rhubarb?

Rhubarb is a unique looking plant with a very interesting history and it belongs to the Polygonaceae family of plants. Scientifically, it is an herbaceous perennial with leaves growing off the top of a thick rhizome.

Although widely considered as a vegetable, in America, it is considered a fruit, since it is mainly used as a fruit in culinary practices. The leaf stalks are actually the most commonly used parts of rhubarb, sometimes as a dessert or an ingredient in sweet dishes.

It is cultivated throughout the year in different parts of the world, so it is widely available in almost any season. It can be grown in greenhouses, resulting in “hothouse” rhubarb, which is sweeter and deeper red in color, while traditional rhubarb is grown outside.

What does Rhubarb Taste like?

The taste of rhubarb is somewhat similar to that of green apples, which is to say that it is tart. Usually, people add sugar to make it sweeter and then bake or cook it.

It is also often paired with strawberries because of the lovely pair of tart and sweet that they make. Some people also often compare the taste of rhubarb with celery.

Is Rhubarb Poisonous?

Interestingly enough, the stalks are the only things eaten from this plant, because the triangular leaves are extremely high in oxalic acid, which can cause severe illnesses in people, resulting in the common belief that rhubarb is poisonous. If the plant is subject to extreme cold, the dangerous acid can migrate into the stalk, so be sure to store rhubarb in a warm or temperate space, just like the climate it normally grows in.

Nutritional Value of Rhubarb

One of the main reasons why people cultivate and eat rhubarb is for its astounding nutritional value. Rhubarb is packed with minerals, vitamins, organic compounds, and other nutrients that make it ideal for keeping our bodies healthy. According to the USDA National Nutrient Database, these precious components are dietary fiber, protein, vitamin C, vitamin K, B complex vitamins, calcium, potassium, manganese, and magnesium. In terms of organic compounds, rhubarb is a rich source of polyphenolic flavonoids like beta-carotene, lutein, and zeaxanthin.

Health Benefits of Rhubarb

Let’s see how the nutrients add up to the long list of health benefits that rhubarb can impart!

Weight Loss

Rhubarb is one of the vegetables with low calories and it is often recommended for people who are struggling to lose weight but still want to remain healthy. 100 grams of rhubarb contains only 21 calories, so feel free to load up on the rhubarb without packing on any pounds. The impact that the various organic compounds in rhubarb have on the body’s metabolism can also dramatically increase the rate at which the body burns fat, thereby helping you lose weight in another way!

Treats Heart Diseases

Rhubarb is extremely low in fat and cholesterol and it poses no threat to cardiovascular health. It can actually increase the levels of good cholesterol due to the presence of dietary fiber, which is known to scrape excess cholesterol from the walls of blood vessels and arteries. Furthermore, there are an impressive amount of antioxidants in rhubarb, according to a study published in the Food Chemistry journal. This ensures that free radicals don’t cause heart disease and a wide range of other dangerous health conditions.

Aids in Digestion

Our digestive system plays a huge part in our overall health, so it is important to keep the digestive system healthy and regulated. The high amount of dietary fiber found in rhubarb can guarantee a healthy digestive system by bulking up the stool and making sure that bowel movements are smooth and regular. Rhubarb has traditionally been used as a cure for constipation, but it was only recently discovered why it had such a powerful effect. By easing constipation and other digestive issues, you can prevent a wide range of more serious gastrointestinal disorders, including bloating, cramping, and even colorectal cancer.

Prevents Alzheimer’s

The most prominent vitamin in rhubarb is actually vitamin K, which plays a very significant role in brain and neural health. It can prevent the oxidation of brain cells and stimulate cognitive activity, thereby helping to delay or even prevent the onset of Alzheimer’s disease, as per the Journal of Beijing University of Traditional Chinese Medicine.

Improves Bone Health

Along with its role in protecting the brain from neural degeneration, vitamin K also promotes osteotropic activity, meaning that it stimulates bone growth and repair. Combined with the rich amount of calcium and other minerals found in rhubarb, the vegetable as a whole is a major player in bone protection.

rhubarbinfoPrevents Cancer

Antioxidants have been widely studied in recent years due to their ability to neutralize free radicals throughout the body. Free radicals are by-products of cellular metabolism that can cause healthy cells to mutate or die, often resulting in cancer or other chronic diseases. According to the researchers from the National University of Singapore, anthraquinones from rhubarb possesses anti-cancer properties.

Rhubarb is a good source of beta-carotene and other polyphenolic compounds like lutein and zeaxanthin which act in a similar way to vitamin A, protecting the skin and eyes from the effects of free radicals. A decent amount of antioxidants in your diet can help avoid premature aging, cataracts, macular degeneration, and wrinkles. Furthermore, these polyphenolic compounds have been connected to preventing oral and lung cancers as well!

Improves Blood Circulation

The trace amounts of copper and iron found in rhubarb are enough to stimulate the production of new red blood cells, increasing the total RBC count in the body as well as oxygenation to essential areas of the body, thereby improving their function and boosting the overall metabolism of the body.

Treats Diabetes

The presence of a compound called rhaponticin in rhubarb helps improve the blood sugar levels in people and thereby helps prevent the condition of diabetes.

Other Benefits

Improves Vision

Rhubarb contains vitamin C and lutein, which are compounds that are very beneficial for good vision.

Treats Perimenopause Symptoms

This amazing plant can also help with perimenopause symptoms by reducing the occurrences of hot flashes, due to the presence of phytoestrogens.

Skin Care

Rhubarb being rich in vitamin A, an antioxidant, helps fight off free radicals and therefore delays the signs of aging including wrinkles and fine lines. It also acts as an antifungal and anti-bacterial agent and prevents skin infections and acne.

  • Strawberry rhubarb pie

Also, be careful that children or pets do not eat the rhubarb leaves. There have been some cases of death due to the toxic levels of oxalic acid contained in the leaves. Other than that, rhubarb is a delicious and beneficial food for you and your family to enjoy!
