Spinach Is Good For Youin Regular Doses

Why spinach is not good for kidney stones?

Spinach has a lot of health benefits like improving eyesight, preventing cancer, and lowering blood pressure. It also is a great source of vitamin A, vitamin C, vitamin K1, iron, calcium and folic acid. So incorporating spinach into your diet is a great idea.

But, like most good things, too much of it can cause some serious damage. Since spinach is so high in calcium and oxalates, this can sometimes cause kidney stones if you consume too much spinach, especially if you arent drinking enough water everyday.

And if youre on a blood thinner, you should talk to your doctor before ingesting too much spinach because vitamin K1 plays a big role in blood clotting. This means eating too much of vitamin K1 can offset the effects of your blood thinner making it super dangerous, so definitely talk to your doctor first if this applies to you.

What Are Kidney Stones

A kidney stone is a large crystal-like mass that forms in the kidneys. These stones can stick inside the kidneys and block the flow of urine and might cause pain. In other cases, the stones may break and travel through the urinary tract causing great pain.

Kidney stones can be caused by several factors, but in most cases, they are caused by calcium oxalate. Usually, excessive intake of calcium oxalate in the body to prevent proper excretion of urine. If this happens, urine starts to crystallize, forming kidney stones. According to research, the recommended amount of oxalate in the body should be between 40 to 50 grams per day.

Can Diet Alone Treat Kidney Stones

For some people, dietary changes may be enough to prevent kidney stones from occurring.

In other cases, additional treatment may be necessary, including medication to break the stones up or surgery to remove the stones.

If stones become extremely painful, it is best to seek consultation with a doctor or nephrologist so they can recommend the best course of action.

Oxalates In Spinach And Kidney Stones Risk

When consumed moderately, spinach is good for the kidneys as antioxidants like vitamin C in it protect the kidneys from free radical damage, and dietary fibers improve kidney health by helping with detoxification.

However, excessive consumption of spinach is bad for the kidneys.

Oxalates present in the spinach are efficiently removed by our kidneys through urine.

However, when spinach is consumed in excess then the high concentration of oxalates may cause damage to the kidneys.

In high concentration, oxalates in the spinach bind with the calcium of the body to form calcium oxalate, a common cause of kidney stones.

Effectiveness Of Low Oxalate Diets

According to a report in the September 2013 issue of Expert Opinion on Pharmacotherapy, whether or not it’s necessary to restrict high oxalate foods such as spinach in order to reduce urine oxalate levels depends on the reason for the elevated levels. For example, in people with primary hyperoxaluria, a rare and inherited condition, avoiding spinach or other high oxalate foods may not be of benefit. However, when hyperoxaluria is related to increased gut absorption of oxalate, or if considered idiopathic, which is often milder and not related to a medical condition, dietary oxalate restriction can help. A study published in the December 2013 issue of Urology demonstrated that about 50 percent of people with idiopathic hyperoxaluria and a history of kidney stones were able to decrease their urinary oxalate to normal levels by restricting spinach and other high oxalate foods.

Dont Underestimate Your Sweat

Saunas, hot yoga and heavy exercise may be good for your health, but they also may lead to kidney stones. Why? Loss of water through sweating whether due to these activities or just the heat of summerleads to less urine production. The more you sweat, the less you urinate, which allows for stone-causing minerals to settle and bond in the kidneys and urinary tract.

One of the best measures you can take to avoid kidney stones is to drink plenty of water, leading you to urinate a lot. So, be sure to keep well hydrated, especially when engaging in exercise or activities that cause a lot of sweating.

Stick To 8 Oz Per Serving 3 Times A Week

Nutritionists suggest keeping intake to under 8 ounces a serving, taken no more than thrice a week. Thats the equivalent of about 2 beets run through your juicer for each serving. If you find the flavor off-putting, combine beet juice with other sweeter or palate-pleasing fruit like oranges or apples.12 According to some health gurus, you can have beet juice daily without a problem. But the reality is you need to consult with your doctor before taking such large quantities of the juice. If you are already on blood pressure-lowering medication, this could jeopardize your health. Be sure that there will be no adverse reactions or side effects based on your medical history and other drugs you may be taking. And do not use this as a substitute for your prescribed medication without first checking with your doctor.

Eating Spinach Every Day Will Help You Feel Happier

Spinach – Eating Spinach Every Day, Oxalic Acid & Kidney Stones

Spinach is good for your physical health, but is it beneficial for your mental health as well? As it turns out, eating spinach every day can indeed help make you happier. In fact, the leafy green is considered an antidepressant food, as stated by a study published in the World Journal of Psychiatry. The study asserted that nutrition is closely linked to the health of the brain. Specifically, magnesium, which can be found in spinach, helps stave off depression.

When youre low in phytonutrients like magnesium, youre unfortunately at risk for symptoms of depression and, sadly, nearly 50 percent of Americans have low levels of magnesium, according to a study in Nutrition Reviews, so its a common problem.

Fortunately, upping your magnesium intake will make you feel happier as it affects your level of serotonin, a brain chemical linked to mood. According to Psychology Today, boiled spinach has a significant amount about 160 milligrams of magnesium per cup. The article went on to explain that consuming magnesium can make antidepressant medication more effective and possibly prevent the need for higher doses of medication.

What Are We Saying

We are saying that oxalate is common in foods, and that you have to be careful, but care is a scarce resource. How much care can you give every bite? The graphs say if you eat moderately high oxalate foods the first graph be careful.

Watch portions.

If you are eating one of the six dangerously high oxalate foods, stop eating it.

It is too hard to be careful with those six foods. They have too much oxalate for most of you to handle. So, just say no.

Ways To Avoid Kidney Stones

  • Hydrating often Drinking more water helps prevents kidney stones because it ensures your urine output will be high. Not enough water means your body wont have enough fluids to dissolve the oxalate crystals in your urine.
  • Eating less salt Too much salt in urine can prevent calcium from being reabsorbed into the blood. This causes high urine calcium levels, which lead to stones.
  • Cutting back on animal protein Animal protein is often acidic and can increase uric acid, which can increase the likelihood of calcium oxalate kidney stones.
  • Eating calcium-rich foods Since kidney stones are formed by calcium and oxalates binding in the kidneys, it may seem counterintuitive to put more of that combination in your body. However, it is recommended that you eat calcium and high oxalate foods together, so they bind in your stomach and intestines not your kidneys.

Causes Of Kidney Stones From Beet Juice

Beetroot contains high levels of oxalate. Consuming excess beetroot is one of the major beetroot side effects on kidney. This may increase the chances of the formation of kidney stones especially if you have problems with your kidney. When you eat oxalate it combines with calcium and when the concentration becomes too high, your kidneys arent able to dispose of it fast enough so it crystallizes to form kidney stones. If you eat foods rich in oxalate like beetroot, youre at high risk of having kidney stones. Beets, beet leaves, and beet juices contain 610mg of oxalate per 100g per cup serving while boiled beets contain 675mg of oxalate.

If you like taking beetroot juice it might not be such a good idea since you use more beets and other fruits and veggies to make just a glass of juice. This increases the amount of oxalate you take per day putting your health at risk.

You can limit this amount by drinking other juices that dont include beetroot. You can make green juices or smoothies or try boiling your beetroot. Boiling is said to dilute the oxalate concentration in the beetroot by a significant amount.

What Is Medical Nutrition Therapy

MNT is the use of nutrition counseling by a registered dietitian to help promote a medical or health goal. A health care provider may refer a patient to a registered dietitian to help with the patientâs food plan. Many insurance policies cover MNT when recommended by a health care provider. Anyone who qualifies for Medicare can receive a benefit for MNT from a registered dietitian or nutrition professional when a health care provider provides a referral indicating that the person has diabetes or kidney disease.

One way to locate a qualified dietitian is to contact the Academy of Nutrition and Dietetics at and click on âFind a Registered Dietitian.â Users can enter their address or ZIP code for a list of dietitians in their area. A person looking for dietary advice to prevent kidney damage should click on âRenal Nutritionâ in the specialty field. Dietitians who specialize in helping people with CKD are called renal dietitians.

What Is The Oxalate Content Of Walnuts

A serving of 1/4 cup of walnuts contains around 10-25mg of oxalates. This puts walnuts in the group having a moderate amount of oxalates. As a result, walnuts should be avoided by people struggling with a severe form of kidney stones.

However, even though following a low-oxalate diet, most people should be alright with consuming walnuts every once in a while. Dietary oxalate consumption is often divided into four levels: low oxalate, moderate oxalate, high oxalate, and extremely high oxalate.

Walnuts are in the second group, so theyre not completely restricted on this diet. However, walnuts are also high in fat, and its easy to overindulge on them. So make sure to control how much walnuts you consume even if youre not following a low-oxalate diet.

Giving Up Oxalates For Good Will Fix The Problem

If you happen to be particularly susceptible to calcium oxalate stones, it may be a good idea to reduce your oxalate intake.

However, there is a downside to this dietary recommendation that is often overlooked. Many high-oxalate foods are also rich in fiber, magnesium, potassium, and phytate, all of which inhibit the occurrence of kidney stones.

Thus, instead of avoiding such healthful sources of nutrients altogether, try to consume them in moderation.

Besides, some people are naturally better at absorbing oxalates than others, and thus such oxalate restrictive diets do not apply uniformly to all.

People with unfavorably high oxalate levels can naturally bring down the amount of oxalate absorption by consuming a high-calcium diet.

If your urine oxalate level continues to be high regardless, ask a dietitian or other health care professional about how strictly you need to avoid oxalate-containing foods.

All in all, eliminating oxalate-rich foods from your diet alone will not prevent calcium oxalate kidney stones from forming and will only give you a false sense of security.

Research suggests that the best way to curb stone formation is to pair high calcium foods with oxalate-rich ones during a meal. This allows the two to bind together in the stomach and intestines before the kidneys begin processing them, making it less likely that kidney stones will form.
