According to the National Kidney Foundation, cruciferous vegetables such as broccoli are rich in vitamin C, fiber, potassium and antioxidants that are beneficial for kidney health.
Kale with similar characteristics is also rich in glucosinolates, sulforaphane, and polyphenols.
A scientific overview published in PubMed shows that these compounds have antioxidant, anti-inflammatory and supportive effects on many organs in the body.
Kidney function support mechanism:
Antioxidant
Oxygenated stress is an important cause of chronic kidney dysfunction. Compounds such as sulforaphane in cruciferous vegetables can activate the body's antioxidant protection system.
According to research published in PubMed Central, sulforaphane has the ability to reduce oxidative stress and is considered a potential factor in kidney protection in patients with chronic kidney failure.
Anti-inflammatory
Chronic inflammation plays an important role in kidney damage. Anti-inflammatory compounds in mustard greens help inhibit inflammatory cytokines; reduce kidney tissue damage; and limit the progression of kidney failure.
Studies of cruciferous vegetables show the strong anti-inflammatory properties of glucosinolate and its derivatives.
Supports blood pressure regulation
High blood pressure is the leading risk factor for kidney disease. Green vegetables, including mustard greens, provide natural nitrate to help improve blood vessel function and regulate blood pressure.
Good blood pressure control will help reduce pressure on glomerules, thereby protecting the kidney's filtering function in the long term.
Improve metabolism and blood sugar
Blood sugar disorders (especially diabetes) are a common cause of kidney failure. Studies show that cruciferous vegetables can improve blood sugar control and reduce metabolic oxidative stress.
This contributes to reducing the risk of kidney damage due to metabolic complications.
According to the National Kidney Foundation, adding cruciferous vegetables to the diet is a suitable choice for people at risk of kidney disease or undergoing kidney disease treatment.
Mustard greens can be processed in many ways: boiled or steamed (to maintain the best nutrition), stir-fried quickly with garlic, cooked into soup.
You should limit cooking for too long because it can reduce the content of vitamins and biological active ingredients.
According to experts from the National Institutes of Health, a diet rich in green vegetables can support kidney health but must be individualized for each patient.
