An unhealthy diet, which includes excessive consumption of unhealthy food, is a recognized risk factor for hypertension. A balanced diet is recommended for both its prevention and control. [20] Dietary sodium intake also contributes to blood pressure. Approximately one third of the essential hypertensive population is responsive to sodium intake.
[14] There has been evidence from epidemiological studies, human and animal intervention experiments supporting the links between high rate of salt intake and hypertension. [2] [15] A Cochrane review and meta-analysis of clinical trials showed that reduced sodium intake reduces blood pressure in hypertensive and normotensive subjects.
For most people, recommendations are to reduce blood pressure to less than or equal to somewhere between 140/90 mmHg and 160/100 mmHg. [2] In general, for people with elevated blood pressure, attempting to achieve lower levels of blood pressure than the recommended 140/90 mmHg will create more harm than benefits, [3] in particular for older people.

“The daily recommended sodium intake for children is less than 1,500 mg, and for adults, it's less than 2,300 mg, with even lower limits for those at risk of high blood pressure, dietitian Mimi ...
According to the American Heart Association, adequate potassium intake lessens the potential blood-pressure-raising effects of excess sodium. Specifically, potassium prompts your kidneys to remove ...
Estimated sodium intake ≥6 g/day and <3 g/day are both associated with high risk of death or major cardiovascular disease, but the association between high sodium intake and adverse outcomes is only observed in people with hypertension. [103]
“The DASH diet is very similar in concept to the Mediterranean diet but has an emphasis on low sodium intake for heart health, striving for the daily recommended intake of 1500-2300 mg of sodium ...
A low sodium diet has a useful effect to reduce blood pressure, both in people with hypertension and in people with normal blood pressure. [7] Taken together, a low salt diet (median of approximately 4.4 g/day – approx 1800 mg sodium) in hypertensive people resulted in a decrease in systolic blood pressure by 4.2 mmHg, and in diastolic blood pressure by 2.1 mmHg.
