^a In the DASH-Sodium trial, the average sodium intake was 1.5 g (65 mmol) as estimated by mean urinary excretion. The sodium intake of each participant was indexed to calorie level (0.9 to 1.8 g/d (39 to 78 mmol, corresponding to 1,600 to 3,600 kcal/d), Svetkey et al. (1999a).

^b Nutrients not analyzed but for which Recommended Dietary Allowances (RDAs) or Adequate Intakes (AIs) have been established (IOM, 1997, 1998, 2000b, 2001, 2002): chromium, copper, fluoride, iodine, iron, manganese, molybdenum, phosphorus, selenium, vitamin A, vitamin D, vitamin K, folate, pantothenic acid, biotin, and choline.

^c Average of recommended intake for young adult men and women; AI indicated with *; all others are RDAs.

^d As low as possible while consuming a nutritionally adequate diet.

^e AI for men for n-3 fatty acids = 1.6 g; for n-6 fatty acids = 17 g; total = 18.6 g.

^f n-3 fatty acids = 0.5–1.0 % of kcal; n-6 fatty acids = 5–10% of kcal.

^g Amount listed is based on 14 g dietary fiber/1,000 kcal.

^h Vitamin E RDA is 15 mg d-α-tocopherol; 1 mg ≈ 1.2 mg d-α-tocopherol equivalents.
