Yes, onions are excellent for kidney health as they are low in potassium, sodium, and phosphorus, making them a kidney-friendly flavor enhancer, rich in antioxidants like quercetin to reduce inflammation, and a great salt substitute for people with kidney disease. They provide flavor and nutrients without adding excessive minerals that can burden compromised kidneys.
Rich in Antioxidants – Onions contain quercetin, a powerful antioxidant that helps reduce inflammation and protect cells from damage. This is especially beneficial for kidney patients, as inflammation is a common issue in chronic kidney disease (CKD).
Diabetes and high blood pressure are the top culprits damaging kidneys most, as they harm the delicate filtering blood vessels, leading to chronic kidney disease (CKD) and failure; other major factors include smoking, obesity, dehydration, poor diet (high sugar/salt/red meat), certain medications (NSAIDs), lack of sleep, and genetic conditions. These factors create a cycle where damaged kidneys worsen blood pressure, further damaging them.
To support kidney health, focus on fruits like berries, apples, and red grapes; vegetables such as cauliflower, red peppers, and leafy greens; lean proteins like fish (salmon) and egg whites; and healthy fats from olive oil, using herbs and spices instead of salt for flavor, as a varied diet rich in whole foods helps filter toxins and manage inflammation.
3. Strengthens Liver Function Daily onion consumption has been shown to reduce ALT (alanine transaminase)--a key liver enzyme--by up to 90% in just 12 weeks. Whether or not you know you have liver issues, eating onions regularly supports detoxification and liver repair. 4.
An Onion a Day also brings the flavor
With their high Vitamin C content, gut-friendly prebiotics, and powerful antioxidants, they offer a surprising number of health benefits. Plus, they make everything taste better.
Eating raw onions in the morning on an empty stomach can maximize their detoxifying properties. Onions help flush out toxins, improve liver function, and kickstart your metabolism.
Garlic. Apart from being used as a food flavoring, garlic also has many health benefits, including maintaining kidney health. Garlic is a source of manganese, vitamin B6, and vitamin C which are good for the body. Additionally, it also contains sulfur compounds that have anti-inflammatory properties.
To strengthen your kidneys, focus on a healthy lifestyle: stay hydrated with water, eat a balanced diet low in salt and processed foods, exercise regularly, maintain a healthy weight, and avoid smoking and excessive alcohol, while also managing blood pressure and blood sugar to prevent damage.
Diabetes is the leading risk factor for kidney disease and the most common cause of kidney failure. High blood sugar from diabetes damages your kidneys and lowers their ability to filter waste and fluid from your blood. Over time, this causes kidney disease.
Top 10 Drinks That Support Kidney Function and Detox
Onions are rich in dietary fibre, which can help lower high creatinine levels. They also contain a good amount of folic acid, which is important for managing creatinine levels.
Since high blood pressure is a risk factor for kidney disease, natural ways that lower it may help protect the kidneys. Cruciferous vegetables like cabbage are packed full of phytochemicals. These are compounds in fruits and vegetables that break up free radicals before they can do any damage.
Special renal vitamins are usually prescribed to provide extra water soluble vitamins needed. Renal vitamins contain vitamins B1, B2, B6, B12, folic acid, niacin, pantothenic acid, biotin and a small dose of vitamin C.
There's no cure for chronic kidney disease (CKD), but treatment can help relieve the symptoms and stop it getting worse.
For instance, turmeric supplements may increase your risk of kidney stones, especially if this runs in your family. Curcumin supplements contain much higher concentrations of the compound than a person would consume by eating food flavored with the spice or by drinking turmeric tea.
You can check kidney function at home using at-home test kits for urine (detecting protein/albumin) or finger-prick blood tests (checking creatinine/eGFR), often with smartphone apps for analysis, or by monitoring symptoms like increased nighttime urination (nocturia), swelling, or changes in urine (blood, foam) and discussing results with a doctor, as home tests screen but don't replace professional diagnosis.
Hsiao or Astragalus membranaceus (Fisch.) Bge. (Family Leguminosae). It is one of the most widely used herbs in traditional Chinese medicine for treating kidney diseases.
To support kidney health, focus on fruits like berries, apples, and red grapes; vegetables such as cauliflower, red peppers, and leafy greens; lean proteins like fish (salmon) and egg whites; and healthy fats from olive oil, using herbs and spices instead of salt for flavor, as a varied diet rich in whole foods helps filter toxins and manage inflammation.
Acute kidney failure can be caused by factors like severe dehydration, infections, or blockages. The good news is that with the right treatment, it's often possible to reverse kidney disease in these cases. Your kidneys can return to normal function after the underlying issue is resolved.
They're rich in chemicals that can help protect your heart, lower your risk of some cancers, and make it easier for your body to make insulin. Onions are also one of the greatest vegetable sources of quercetin, a plant compound with many health benefits.
Are onions good for you?
A 2017 study published in Food Research International found that red onions were most effective at killing human cancer cells compared with other onions thanks to their higher levels of the antioxidants quercetin and anthocyanin.
