Low-Sodium Meal Plan for Hypertension

The 2017 ACC/AHA guideline recommends less than 1,500 mg of sodium per day for most adults with hypertension where feasible, and less than 2,300 mg as a reasonable upper limit. A slice of commercial white bread can supply 150 to 230 mg, a cup of canned soup 800 to 1,200 mg, and a restaurant sandwich often 1,500 mg or more. Cooking at home with unsalted or low-sodium ingredients is the most effective change. Confirm a personalized target with your physician, particularly if you take diuretics.

In the DASH-Sodium trial, combining the DASH eating pattern with a sodium intake of about 1,500 mg per day lowered systolic blood pressure by 8.9 mmHg in people with Stage 1 hypertension, and by 11.5 mmHg in those with the highest baseline blood pressure. Most of the effect appeared within two to four weeks of consistent adherence. Individual response varies; people who are salt-sensitive (often older adults, Black adults, and people with kidney disease) tend to respond more strongly to sodium reduction.

Not if you build flavor intentionally. Fresh and dried herbs, black pepper, lemon juice, vinegars, garlic, ginger, mustard, smoked paprika, and nutritional yeast add depth without sodium. Roasting vegetables concentrates natural sugars and creates savory browning. Searing proteins builds umami. The palate recalibrates within two to three weeks; foods that once tasted normal will start to taste overly salty, and natural flavors become more distinct.

DASH targets approximately 4,700 mg of potassium and 1,200 mg of calcium per day. Top potassium sources per USDA data include a medium baked potato with skin (926 mg), a cup of cooked white beans (829 mg), a cup of Swiss chard (961 mg), and a medium banana (422 mg). For calcium, plain dairy, calcium-set tofu, canned salmon with bones, and fortified plant milks are reliable sources. Consult your physician before increasing potassium if you take ACE inhibitors, ARBs, or potassium-sparing diuretics — these medications can raise serum potassium and require lab monitoring.

Use them strategically. Frozen plain vegetables and unseasoned frozen fish are typically very low in sodium and convenient. For canned goods, choose no-salt-added or low-sodium versions, which have 140 mg or less per serving. Rinsing regular canned beans for a minute under cold water reduces sodium by 30 to 40 percent. Watch for hidden sodium in tomato sauce, broth, bread, cottage cheese, and prepared condiments, which often supply more than their flavor suggests. The shopping-list output sorts by sodium so the dominant items are visible.
