Oxalic acid is a normal part of the metabolic process. Your body literally creates it during digestion. Avoiding all oxalic acid intake is a nutrition myth and is basically impossible anyway. Fruits contain it, vegetables contain it, grains contain it. You eat it constantly. This person was already severely unhealthy if they gave themselves NAFLD and kidney stones. More likely the crap peanut butter OP was eating was full of preservatives and icing sugar and OP is probably chronically dehydrated.
A few people are in here saying a pound or two a week is an unreasonable amount of peanut butter.
But when you buy peanut butter it comes in a 1-2 pound jar. If it's your main source of protein, your favorite comfort food, or you have a poverty pantry, then I could totally see how you might think that one jar a week isn't too bad.
Two pounds of peanut butter is about 6000 calories, or three days of energy for the average person. It shouldn't be the main staple in your diet, as OPs doctor will attest, but it doesn't seem strictly unreasonable.
I wonder how gourmet or homemade "nothing but peanut" butter compares to something like Kraft that's loaded with sugar. Probably still not super great, but hey, maybe it's better. Or maybe it's worse. Eat a variety if you can.
A pound or two a week sounds kind of moderate? I mean it's a lot, but if you like peanut butter? I don't eat nearly that much of it on average, but when I buy a 1 pound jar I usually finish it off in much less than a week. It's just an occasional thing for me though.
Are those oxalates only if the PB is getting spoiled or anything like that?
A pound of peanut butter per week sounds insane but apparently it's only like 2 cups and I feel like that's an edible amount. It's a lot but if I really got a hankering for some PB I could do that. But then after a week I would be over it. I feel bad for this person though that apparently they think eating nothing but PB is healthy. A human body needs a variety of different foods and nutrients and evidently eating nothing but peanut butter isn't that.
A pound of peanut butter is around 2600 calories. A pound of Nutella is about 2400 calories. Honestly not as bad as I thought initially.
1 to 2 pounds a week is 370 to 740 calories per day. Eating that much peanut butter for a week or so wouldn’t be too hard, but keeping that rate up consistently would be tough.
The quantity doesn't seem right to me, a normal american peanut butter jar is about 2 pounds. I feel like if the only thing you eat in a day is peanut butter that by itself would be about a half a jar right? Calories would put it at ~1/3 a jar for daily caloric intake but obviously you're going to overshoot if you're eating straight peanut butter. Half a jar in a week just doesn't sound that crazy to me, thats barely over 2 servings/day.
Also peanuts are low in oxalates compared to other nuts. The number I keep finding for a low oxalate diet is 100 mg/day. Apparently 200-300 is a typical amount. The highest number I found is 20mg of oxalate to a tablespoon of PB so 2 pounds a week is only 160mg/day unless I messed up the math.
*I think what happened here is OP is either predisposed to kidney stones and is generalizing the special diet they should be on to everybody else or is just overweight and leaving out that detail since everything I'm reading about NAFLD is that it's caused by obesity not oxalates.
Apparently this can really happen.
our patient consumed an estimated five times the typical quantity of oxalate daily. She ingested approximately 150 g of almonds daily ... and six tablespoons (1/8 cup) of chia seeds ... which ultimately caused kidney injury.
150 grams is ~130 almonds, and the chia seeds weigh ~90 grams. I'm surprised it took only 240 grams (about half a pound) of nuts/seeds a day to get sick but that's still way more than most people eat and the relationship between dose and kidney disease isn't linear.
Normally, small amounts of free oxalate are absorbed by the stomach, distal small intestines and colon in humans.
I remember my grandmother who lived to age 98 told me about an "all-day sucker" - basically fill a spoon in peanut butter, and when it's done, fill it up again. Repeat all day. Can you tell she lived during the depression?
I didn't think much of it as a kid. Thought it was a pretty good idea. Then I learned about food sanitation practices, and reconsidered.
The only reason I knew peanuts could be bad for your kidneys is watching Dr. Glaucomflecken and seeing his sketch of the nephrologist at Halloween. https://www.youtube.com/watch?v=IAghdVqVJUg
Oh wow 😯. I do like peanut butter but I didn't know about the oxalate content. Now I have to research this. I have this new hobby of cyanotype and the newformula by Mike Ware is what I'm using. It contains oxalates. I never touch the stuff as I apply it. But sometimes I stick my fingers into the developing bath without gloves. Hmm. Well now I'm going to wear gloves. But I also want to read the MSDS.
ITT: people underestimating the density of peanut butter
The word "liver" doesn't appear in the Wikipedia article.
As for oxalates:
Several plant foods such as the root and/or leaves of spinach, rhubarb, and buckwheat are high in oxalic acid and can contribute to the formation of kidney stones in some individuals. Other oxalate-rich plants include fat hen ("lamb's quarters"), sorrel, and several Oxalis species (also sometimes called sorrels). The root and/or leaves of rhubarb and buckwheat are high in oxalic acid.[14] Other edible plants with significant concentrations of oxalate include, in decreasing order, star fruit (carambola), black pepper, parsley, poppy seed, amaranth, chard, beets, cocoa, chocolate, most nuts, most berries, fishtail palms, New Zealand spinach (Tetragonia tetragonioides), and beans.[citation needed] Leaves of the tea plant (Camellia sinensis) contain among the greatest measured concentrations of oxalic acid relative to other plants. However, the drink derived by infusion in hot water typically contains only low to moderate amounts of oxalic acid due to the small mass of leaves used for brewing.[citation needed]
but no mention of peanuts in the main or talk page.
The doctor might be wrong.
But it's so good though.....
eh, I've only been eating rice and popcorn for the last 2 days...
Damn, not regularly but a few times I have ate that much peanutbutter in less time.
