Eating With High Blood Pressure: Salt, Potassium and What Helps
With high blood pressure, cutting salt and adding potassium-rich foods does most of the work. And most salt does not come from the salt shaker.
Diet genuinely affects blood pressure — but not from where most people look. The shaker on the table is a small part of the total.
How much salt, and from where
Less than 5 grams a day for adults — about a teaspoon, including what goes in while cooking. The real quantity comes from:
- Pickles, papad and chutneys
- Namkeen, chips and bhujia
- Biscuits and bread
- Packaged soups, masala mixes and instant noodles
- Restaurant food and gravies
What to eat
- Plenty of fruit and vegetables — banana, orange, papaya, spinach, lauki, tomato
- Pulses, rajma and chhole
- Whole grains — bajra, jowar, dalia
- Curd and buttermilk, unsalted
- Unsalted nuts and seeds
- Garlic, lemon, coriander and pepper — flavour that replaces salt
What potassium does
Potassium helps balance the effect of sodium, so more fruit and vegetables works twice over. One important exception: in kidney disease potassium has to be limited, and this advice does not apply there.
What to cut back
- Adding salt at the table
- Daily fried food
- Processed and packaged food
- Heavy alcohol
- Very strong tea or coffee if it sets your heart racing
Your palate adjusts
Cutting salt sharply makes food taste flat and most people give up within a fortnight. Reduce gradually — in two or three weeks the palate resets and lower-salt food tastes normal.
Frequently asked questions
Do I have to cut salt out entirely?+
No. The body needs some. The aim is to reduce, not eliminate.
Is rock salt better?+
It still contains sodium. Treating it as safe and using more gains nothing.
Can diet let me stop medication?+
Lifestyle improves readings considerably for some people, but stopping medication is always a doctor’s decision.
Can I eat bananas?+
Generally yes — they carry useful potassium. With kidney disease, only on your doctor’s advice.
