Impaired Kidney Function

I have been eating under 50gms of carbohydrates for the past 18 months. I am limited to eating chicken, fish, eggs, celery, green beans, carrots and banana. I only drink water.

I had a blood test before I started this diet and one just recently. Unfortunately, my recent blood test came back with moderately impaired kidney function. I am sure this is from increasing my protein intake eg 6 eggs a day, most of a roast chicken a day.

Jimmy, I heard you on a podcast say you eat mainly meat and eggs. Do your kidneys struggle with the protein intake

Has anyone else found that their kidneys struggle with low carb, high fat and protein intake?

The only option I can think of now is to increase my carbs and decrease my protein.

Many thanks for any help you can give.

]Consumption of long-chain n-3 PUFA, α-linolenic acid and fish is associated with the prevalence of chronic kidney disease.
Quote:increased dietary intake of long-chain n-3 PUFA and fish reduces the prevalence of CKD. Hence, a diet rich in n-3 PUFA and fish could have a role in maintaining healthy kidney function, in addition to roles of these nutrients in the prevention and modulation of other diseases
Although I see fish mentioned it could be that you are not eating sufficient fish or taking sufficient omega 3 fish oil.


There is also plenty of evidence linking low vitamin d status to kidney disease so ensuring your 25(OH)D is around the 50~70ng/ml mark with an EFFECTIVE amount of vitamin D3 is probably going to help. Most people require around 5000iu/daily maybe more in winter.

Increasing your carbohydrates is not your only option. You could instead increase your fat intake and keep an eye on the protein. I would do that before increasing the carbs.

I think my first step is to reduce the amount of roast chicken I eat each day. I have been healing my gut with the Specific Carbohydrate Diet and have been overly reliant on protein in the diet's early stages.

I will increase my fat. Maybe more of the chicken skin rather than the meat and keep the carbs at the level I eat now or a small increase. Thank you for your reply.

Careful - the fat nearest the skin of chicken is supposed to be richest in Omega-6s, and chicken fat generally is likely to be richer in PUFAs than either beef or lamb. (Pork is also suspect in this respect - a lot has to do with the way the animals are fed, but in general it's hard to be sure about how our food animals are fed unless you buy direct from the farm and see how they feed them).


Have you thought of increasing your dairy? This will provide fat, and also Calcium-phosphorous in a better ratio than most meats. And it will provide some protein.


If you can get hold of some fatty, gristly bones/joints of beef or lamb, and boil them up to make a gelatinous bone broth, consume the broth and fatty residues, but leave the flesh , you should be getting some goodness and protein which should not be too much of a load. (Oxtails are good if you can get them; also I think the various cheaper cuts of lamb like middle neck and scrag - but if you have a friendly butcher to ask, so much the better).

That link doesn't work for me.
Also, the title you have given it does not agree with the quote
"associated with the prevalence" or "reduces the prevalence"?

OK, I think I see what's wrong: your first "[/url]" should just be a "]" (I think).

I see you have reproduced their title, but unfortunately, their title is a bit misleading!
