Especially beneficial for calcium oxalate kidney stones
1. At least five studies have shown that a diet high in sugars and refined carbohydrates (white flour products, rice, potatoes, pasta etc) tends to promote the formation of kidney stones. Solution: Avoid or minimize the refined-carbohydrate foods.
2. At least nine studies have demonstrated that a diet low in fiber (especially rice bran) contributes to an increase in kidney stones. The converse has also been shown to be true. 10 grams of rice bran per day reduced the rate of new kidney stone formation by almost 90% in one study! Solution: Increase the fiber in your diet, especially rice bran at 10 grams/day.
3. At least four studies have demonstrated that supplementing with calcium not only does not increase the incidence of new kidney stone formation, but actually decreases it. Solution: Supplement with calcium (carbonate,citrate or lactate) at c. 1,000 mg/day.
4. At least 2 studies have shown that increasing one’s intake of sodium (as table salt) concomitantly increases the excretion of calcium in the urine (which presumably will increase the risk of new kidney stone formation). Solution: Avoid excess sodium in the diet.
5. At least 17 studies have shown that increasing one’s intake of vitamin B6 (pyridoxine) and magnesium will dramatically (by over 90%) reduce the incidence of kidney stone formation. Solution: Vitamin B6 10-50 mg per day. Magnesium (as oxide, glycinate, amino acid chelate or hydroxide) at 300 to 500 mg per day.
6. At least five studies demonstrate that a diet low in vitamin A increases the risk of getting kidney stones (and vice versa). Keeping serum vitamin A levels above 13 mcg/dl will reduce this risk of renal calculi (stones). Solution: Supplement with Vitamin A at 10,000 Units per day (not as beta carotene).
CAUTION: Don’t go above 5, 000 units per day if you are pregnant
7. Vitamin C has often been blamed for contributing to calcium oxalate kidney stone formation, because vitamin C is metabolized into oxalic acid. However a number of studies have demonstrated no such link (at least in amounts up to 10 grams of vitamin C per day). Suggestion: It appears to be safe to supplement with vitamin C (less than 10 grams per day) if you have had kidney stones.
8. Lemon Juice & Lemonade: At least 2 studies have shown that ingestion of lemon juice (from 2 lemons/day sweetened with sugar) or lemonade (2 liters per day made from 4 oz of lemon juice concentrate sweetened with sugar or artificial sweetener) resulted in the disappearance of uric acid (not calcium oxalate) kidney stones after about 1 year. This should also work on oxalate stones as it is the citric acid in lemons that does the trick (there’s five times as much citric acid in lemons as there is in oranges). Solution: Take the lemon juice or lemonade as above.
CAUTION: Lemon juice acidity can erode tooth enamel. Always rinse mouth well after ingesting acidy foods like lemon juice or lemonade.
8. Organic Marine Hydrocolloids (OMHs) are natural polymers obtained from seaweed. They are sold commercially as "OxAbsorb by the Vitaline Co. (out of Oregon). Each 1 gram tablet also contains 100 mg of calcium and 1.2 mg of zinc. This product works by providing calcium (see # 3 above) and via its ability to absorb and bind oxalate. Studies show it to be an effective agent for the prevention of kidney stones. Solution: OxAbsorb 3 tablets three times a day (9 grams per day).
9. EPA: EPA stands for eicosa.pentaenoic acid which is found in high amounts in fish oils. In one study 10 grams of fish oil per day resulted in significant reductions in the excretion of both calcium and oxalate into the urine (in just 8 weeks). Solution: Fish oil capsules at 10 grams per day (Nordic Naturals is one of the better brands, and much less "fishy" tasting). Cod Liver Oil is cheaper (and you can find flavored oils if you wish): Suggested dose is two teaspoonsful (10 cc) per day.
10. Drink Lots of water: This keeps the urine dilute and preventss tone formation.
