Key MethodWe analyzed nutritional habits of 22 stone formers with special regard to oxalate content as one of the main nutritional lithogenic factors associated with kidney stones. Daily dietary oxalate intake was 354 +/- 261 mg and 406 +/- 265 mg in men and women respectively. These values were much higher than those found by other researches. The main sources of oxalate in diets were regular tea and coffee (80-85%). Only 15-20% of oxalate was derived from other plant foods. Patients did not adhere to…Expand
Eating Habits among Lithiasic Patients in Kinshasa, the Democratic Republic of Congo
TLDR
High consumptions of vegetables and low water intake were linked to the formation of calcium oxalate monohydrate stones, and more data is needed to confirm these findings. Expand
Correlation of the Chemical Composition of Kidney Stones with the Diet Style, Gezira State, Sudan
TLDR
The relationship between dietary habits and incidence of stone formation and the chemical analysis of stones is defined to know the pattern of chemical composition of stones in Sudanese subjects to better understanding of the mechanisms involved in lithogenesis. Expand
Determination of Oxalate Content in Tea Samples by High Performance Liquid Chromatography
Oxalate is one of the major risk factors for kidney stones which become more common in industrialized countries including Thailand. Tea is a significant source of oxalate. There have been a fewExpand
Does green tea consumption increase urinary oxalate excretion? Results of a prospective trial in healthy men
TLDR
In vitro studies showed that there was a gradual increase in solution concentrations of oxalate that was associated with increased brewing time and increased quality of green tea, and studies in normal men showed that green tea consumption wasassociated with increased urinary exertion of oxAlate.

Tea Consumption is Associated with Increased Risk of Kidney Stones in Northern Chinese: A Cross-sectional Study.
TLDR
After adjusting for sex, age, and other potential confounding factors, tea consumption still significantly increased the risk of kidney stones in the investigated population, suggesting that a decrease in the consumption of tea may be a preventive strategy for kidney stones. Expand
Effect of different brewing times on soluble oxalate content of loose-packed black teas and tea bags
TLDR
There was a stepwise increase in oxalate concentration associated with increased brewing times, and the effect of different brewing times on soluble oxalates contents of loose-packed black tea and tea bags was studied. Expand
A Study of Diet and Lifestyle and the Risk of Urolithiasis in 1,519 Patients in Southern China
TLDR
High consumptions of pickled foods and animal protein were the main risk factors for the development of urolithiasis in a population of southern China, but high fluid intake with a preference for strong tea, a diet of vegetables, and physical exercise were protective factors. Expand

Dietary risk factors for hyperoxaluria in calcium oxalate stone formers.
TLDR
Findings suggest that hyperoxaluria predominantly results from increased endogenous production and from intestinal hyperabsorption of oxalate, partly caused by an insufficient supply or low availability of calcium for complexation with oxalates in the intestinal lumen. Expand
Intake of vitamins B6 and C and the risk of kidney stones in women.
TLDR
A high intake of vitamin B6 was inversely associated with risk of kidney stone formation, and routine restriction of vitamin C to prevent stone formation appears unwarranted. Expand
Substituting milk for apple juice does not increase kidney stone risk in most normocalciuric adults who form calcium oxalate stones.
OBJECTIVE Increasing intake of dietary calcium from less than 400 mg to 800 mg daily may decrease the absorption of dietary oxalate, which in turn would decrease urinary oxalate excretion. The effectExpand
Body Weight, Diet and Water Intake in Preventing Stone Disease
TLDR
The fundamental aspects of the nutritional approach to the treatment of idiopathic nephrolithiasis are body weight, diet and water intake, which will present data resulting from investigations and the most significant evidence in literature. Expand
The impact of dietary oxalate on kidney stone formation
TLDR
Differences in dietary oxalate intake and in renalOxalate excretion are two other parameters that are likely to receive close scrutiny in the near future, because the research tools required for these investigations are now available. Expand
Reference range for gastrointestinal oxalate absorption measured with a standardized [13C2]oxalate absorption test.
PURPOSE Hyperoxaluria is a prominent risk factor for calcium oxalate urinary stones. Oxalate in urine is synthesized in the body or absorbed from food in the gastrointestinal tract. The amount ofExpand
Bioavailability of soluble oxalate from tea and the effect of consuming milk with the tea
TLDR
These studies show that consuming black tea on a daily basis will lead to a moderate intake of soluble oxalate each day, however the consumption of tea with milk on a regular basis will result in the absorption of very little oxalates from tea. Expand

TLDR
A 32-year-old truck driver who suffered from renal stones and was referred for metabolic protein intake to 5–7 servings per week, to lower evaluation of severe recurrent calcium stone disease, was told to lower meat protein intake more and to nephrolithiasis with idiopathic hypercalciuria. Expand
Urinary oxalate is not increased by vitamin B-6 depletion in young women
Although acute vitamin B-6 deficiency increases urinary oxalate excretion, the effects of marginal vitamin B-6 status are unknown. Mild vitamin B-6 depletion was induced in eight healthy young womenExpand
Oxalate absorption and endogenous oxalate synthesis from ascorbate in calcium oxalate stone formers and non-stone formers.
TLDR
The finding that ascorbate supplementation increased urinary total and endogenous oxalate levels suggested that this practice is a risk factor for individuals predisposed to kidney stones. Expand
