Rhubarb and its health benefits
At present, we do not have scientific studies that present solid data to support the health benefits of rhubarb. Nonetheless, anecdotal information and some research suggest it may help prevent some diseases. What benefits can rhubarb offer us?
Regulates cholesterol levels
Rhubarb stalks provide a significant supply of fiber, which helps regulate cholesterol levels. According to a controlled study published in the Journal of the American College of Nutrition , the fibers contained in the rhubarb stem reduce total cholesterol by 8% and bad cholesterol (LDL) by 9%.
As a publication in Research in Pharmaceutical Sciences reports , antioxidants play an important role in the prevention of chronic disease. They don’t just reduce the negative effects of free radicals, they also strengthen the immune system and help fight inflammation.
Rhubarb is a good source of antioxidants, superior even to cauliflower, as seen in a study published in the International Journal of Food, Science & Technology . Specifically, it contains anthocyanins, which contribute to the improvement of cardiovascular, brain and skin health.
The fibers contained in the rhubarb stem also have a positive effect on digestive health. Their regular consumption is believed to contribute to the prevention and treatment of some gastrointestinal disorders, such as constipation.
On the other hand, a study conducted on guinea pigs and published in BioMed Research International states that the tannins in rhubarb regulate the absorption of water in the digestive system, thus preventing diarrhea.
Side effects of rhubarb
Moderate rhubarb consumption has no negative consequences for most healthy adults. It is good to know, however, that it is one of the most important dietary sources of calcium oxalate, mainly contained in the leaves. Excessive consumption must therefore be avoided.
As reported in a report shared by BMC Nephrology , an excess of calcium oxalate can cause hyperoxaluria, a frequent cause of kidney stones. Without proper treatment, it could cause kidney failure.
As a result, this vegetable must be avoided by those suffering from kidney disease or who have suffered from stones. It is good to consult your doctor before consuming rhubarb on a regular basis in case you are following a drug treatment.
