title: Dietary nutrient intakes and slight albuminuria in people at least 40 years old.
abstract: We studied the relation between diet and slight albuminuria in 5416 people, ages 40 years and over, who participated in a health screening survey of a local workforce. Degree of albuminuria showed log-linear univariate relations with dietary protein, cholesterol, and sodium intakes, and negative log-linear univariate relations with dietary fiber and polyunsaturated to saturated fat (P/S) ratio. After adjusting for age, gender, and ethnicity, the relative risk (95% confidence interval) for slight albuminuria was significantly increased in people reporting dietary cholesterol consumption > 226 mg/day compared with people reporting consumption < or = 226 mg/day [1.32 (1.02, 1.70)], and significantly reduced in people reporting dietary fiber consumption > 26 g/day compared with people reporting consumption < or = 26 g/day [0.74 (0.58, 0.95)]. There was no significant effect of dietary protein, P/S ratio, or salt intake. We conclude that risk of slight albuminuria is increased by consumption of dietary cholesterol and reduced by consumption of dietary fiber.
