DASH Diet Limits for Foods with Restricted Intake
For a DASH diet, limit sodium to ≤2,300 mg/day (ideally 1,500 mg/day), added sugars to no more than 100 kcal/day for women and 150 kcal/day for men, and saturated fat to <6% of total daily calories. 1
Sodium Restrictions
- Daily sodium intake should not exceed 2,300 mg/day, with an optimal target of 1,500 mg/day for those with hypertension or at higher cardiovascular risk 1
- Approximately 75% of dietary sodium comes from processed and restaurant foods rather than table salt, so focus restriction efforts on these sources 1
- The "salty six" foods providing the most sodium in the US diet include bread and rolls, cured meats, pizza, poultry, soup, and sandwiches 1
- Rinse canned vegetables with salt to reduce sodium content before consumption 1
Added Sugar Limits
- Women should consume no more than 100 kcal/day from added sugars (approximately 6 teaspoons or 25 grams) 1
- Men should limit added sugars to no more than 150 kcal/day (approximately 9 teaspoons or 38 grams) 1
- Children should consume less than 100 kcal/day from added sugars based on their total energy needs 1
- The 2015-2020 Dietary Guidelines specify that added sugars should not exceed 10% of total energy needs 1
- Sweets and added sugars should be limited to 5 or fewer servings per week in the DASH eating pattern 1
Specific Serving Sizes for Sweets (When Consumed)
Saturated Fat Restrictions
- Limit saturated fat to <6% of total daily calories for those needing LDL cholesterol reduction 1
- The general population should keep saturated fat below 10% of total calories 1
- Avoid trans fats entirely, as they increase cardiovascular disease risk and mortality 1
- Replace saturated fats with polyunsaturated and monounsaturated fatty acids rather than refined carbohydrates 1
Fats and Oils Serving Sizes
- 2 to 3 servings per day from the fats and oils group 1
- 1 teaspoon soft margarine or vegetable oil (canola, corn, olive, soybean, safflower) 1
- 1 tablespoon regular salad dressing equals 1 serving 1
- 2 tablespoons low-fat dressing equals 1 serving 1
- 1 tablespoon mayonnaise 1
Red Meat and Processed Meat Limitations
- Limit lean meats, poultry, and fish to 6 ounces per day in the DASH pattern 1
- Select only lean or extra-lean meats, trim visible fats, and remove skin from poultry 1
- Processed meats (smoked, cured, salted meats, or those with chemical preservatives) should be minimized as they contribute excess sodium and are associated with increased cardiovascular risk 1
- Red meat consumption should be reduced in favor of fish, poultry, nuts, and legumes 1
Sugar-Sweetened Beverages
- Minimize or eliminate sugar-sweetened beverages including soft drinks, fruit drinks, sports drinks, energy drinks, and sweetened tea and coffee drinks 1
- These beverages are associated with a 20% increase in diabetes risk with just one daily serving 1
- Consumption of added sugar at >10% of daily calories has been associated with increased mortality 1
Practical Implementation Considerations
- When reducing saturated fat, avoid replacing it with refined carbohydrates or added sugars, as this substitution does not improve cardiovascular outcomes 1, 2
- Choose preparation methods that preserve nutrient content without adding unnecessary calories, saturated fat, trans fat, sugar, or salt 1
- For nuts, seeds, and legumes (beneficial sources of energy, magnesium, protein, and fiber), choose smaller portion sizes and select salt-free products to manage calorie intake 1
- 4 to 5 servings per week of nuts, seeds, and legumes in the DASH pattern 1
Critical Pitfalls to Avoid
- Do not compensate for reduced saturated fat intake by increasing refined carbohydrates or added sugars, as this worsens the lipid profile and increases cardiovascular risk 1, 2
- Avoid focusing solely on individual nutrients rather than overall dietary patterns, as the complete DASH eating pattern provides superior cardiovascular benefits 1
- Do not add salt during cooking or at the table, as this significantly increases sodium intake beyond processed food sources 1
