Low Sodium Diet: What to Eat, What to Avoid & a 7-Day Indian Meal Plan
By Hafsaa Farooq | Medically Reviewed | Updated April 2026
If you have been diagnosed with high blood pressure, your doctor has almost certainly told you to reduce your salt intake.
But knowing you should eat less salt and knowing how to actually do it in an Indian kitchen are two very different things.
Salt is woven into Indian cooking at every stage, from the tempering to the pickle on the side.
This guide explains how much sodium is safe, where the hidden sodium in Indian diets actually comes from, and how to follow a practical low-sodium diet without giving up the flavours you enjoy.
| Quick Answer: A low-sodium diet limits sodium to 1,500 to 2,000 mg per day (equivalent to about 3/4 to 1 teaspoon of table salt). The average Indian adult consumes 8 to 11 g of salt per day, well above the WHO recommendation of less than 5 g (2,000 mg sodium). Reducing sodium intake by just 1,000 mg per day can lower systolic blood pressure by 5 to 6 mmHg in people with hypertension. [1] |

Why Sodium Raises Blood Pressure
Sodium is an essential mineral that regulates fluid balance in the body.
When sodium intake is consistently high, the body retains more water to dilute the excess sodium in the blood. This increases blood volume, which in turn increases the pressure exerted on artery walls, raising blood pressure. [2]
Over time, persistently elevated blood pressure damages the inner lining of arteries, promotes arterial stiffness, forces the heart to work harder, and accelerates atherosclerosis.
The relationship between sodium and blood pressure is dose-dependent: the more sodium consumed, the higher the blood pressure, and the greater the cardiovascular risk. [3]
The landmark DASH-Sodium trial demonstrated this clearly: reducing sodium intake from a high level (3,300 mg/day) to a low level (1,500 mg/day) reduced systolic blood pressure by 8.9 mmHg in people with hypertension eating a standard diet, and by 4.6 mmHg in those already following the heart-healthy DASH diet. [4]
These are reductions comparable to the effect of a single antihypertensive medication.
| Population impact: A modelling study published in the New England Journal of Medicine estimated that reducing average salt intake by 3 g per day in the United States would prevent 54,000 to 99,000 heart attacks and 32,000 to 66,000 strokes annually. [5] The scale of the benefit in India, where average salt consumption is even higher, would be proportionally larger. |

How Much Sodium Is Safe?
| Guideline / Condition | Daily Sodium Limit | Equivalent in Salt |
|---|---|---|
| WHO recommendation (general population) | Less than 2,000 mg | Less than 5 g (about 1 tsp) |
| American Heart Association (optimal) | Less than 1,500 mg | About 3/4 tsp |
| Hypertension (diagnosed) | 1,500 mg or less | About 3/4 tsp or less |
| Heart failure or kidney disease | 1,000 to 1,500 mg (doctor-guided) | Less than 3/4 tsp |
| Average Indian adult (current intake) | 3,200 to 4,400 mg | 8 to 11 g, 2x the safe limit [6] |
To put these numbers in context: one teaspoon of table salt contains approximately 2,300 mg of sodium. A single serving of instant noodles contains 800 to 1,200 mg. One papad contains 300 to 500 mg. One tablespoon of soy sauce contains 900 mg. It is easy to exceed the daily limit before dinner.
Hidden Sodium in the Indian Diet
Most people focus on the salt they add at the table or while cooking. But in the Indian diet, a significant proportion of sodium is hidden in foods that do not taste obviously salty. These are the sources most people miss when trying to reduce their intake.
| Food Item | Typical Sodium (mg) | Notes |
|---|---|---|
| Instant noodles (1 packet) | 800 to 1,200 | Masala sachet is the primary sodium source |
| Papad (1 piece) | 300 to 500 | A common accompaniment that adds up quickly with meals |
| Pickle/achar (1 tbsp) | 400 to 700 | One of the highest sodium foods per gram in the Indian diet |
| Packaged namkeen / chips (30 g) | 250 to 450 | Bhujia, chakli, mixture all very high in sodium |
| Bread (2 slices commercial) | 250 to 350 | Salt is added during manufacturing |
| Biscuits/crackers (4 pieces) | 150 to 300 | Even sweet biscuits contain significant sodium |
| Cheese (30 g) | 150 to 250 | Processed cheese higher than natural cheese |
| Soy sauce (1 tbsp) | 800 to 1,000 | Extremely high; common in Indo-Chinese cooking |
| Tomato ketchup (2 tbsp) | 300 to 400 | Often used liberally with snacks |
| Salted butter (1 tbsp) | 90 to 100 | Choose unsalted butter where possible |
| Commercial dal makhani / rajma (restaurant) | 600 to 1,000 per serving | Restaurant and packaged versions use far more salt than home cooking |
| Chaas / buttermilk (packaged, salted) | 200 to 400 per glass | The homemade unsalted version is much lower |
| The key insight for Indian households: pickles, papad, and packaged snacks are the three biggest controllable sources of hidden sodium in the daily Indian diet. Eliminating or sharply reducing just these three can remove 700 to 1,500 mg of sodium from your daily intake without changing a single cooked meal. |

Low Sodium Foods: What to Eat
| Category | Best Low Sodium Choices | Sodium per Serving |
|---|---|---|
| Vegetables (fresh) | All fresh vegetables: spinach, tomatoes, capsicum, brinjal, lauki, karela, bhindi, pumpkin, beetroot, cabbage | 5 to 70 mg per 100 g (naturally very low) |
| Legumes and pulses (home-cooked, no added salt during boiling) | Moong dal, masoor dal, chana, rajma, urad dal | 5 to 15 mg per 100 g dry; rises with cooking salt added |
| Whole grains (plain, home-cooked) | Brown rice, oats, jowar, bajra, ragi, whole wheat atta | 1 to 5 mg per 100 g dry; rises with added salt |
| Fresh fruits | All fresh fruits: banana, guava, papaya, apple, orange, amla, pomegranate | 0 to 5 mg per 100 g |
| Unsalted nuts and seeds | Walnuts, almonds, flaxseeds, chia seeds (unsalted only) | 0 to 5 mg per 30 g (salted versions have 70 to 180 mg) |
| Fresh fish and poultry (unprocessed) | Fresh mackerel, rohu, chicken breast (not marinated or processed) | 50 to 80 mg per 100 g |
| Eggs | Whole eggs (1 large egg) | 70 mg per egg |
| Low-fat dairy (unsalted) | Homemade dahi (curd), paneer made without added salt, low-fat milk | 40 to 70 mg per 100 g for dahi; 50 mg per 100 ml for milk |
| Herbs and spices | All fresh and dried herbs and spices: turmeric, cumin, coriander, ginger, garlic, curry leaves | Near zero; use liberally to replace salt for flavour |
| Unsalted homemade chaas | Curd blended with water and roasted jeera (no salt) | 50 to 80 mg per glass vs 200 to 400 mg for salted packaged versions |
Indian Cooking Tips to Reduce Sodium Without Losing Flavour
The biggest concern when reducing salt in Indian cooking is that food will become bland. It does not have to. Sodium provides saltiness, but flavour in Indian food comes primarily from spices, aromatics, and cooking technique. These strategies allow you to cut sodium significantly while keeping meals satisfying:
| Strategy | How to Apply It |
|---|---|
| Build flavour with a stronger tadka | A good tempering of mustard seeds, cumin, curry leaves, dried red chilli, garlic, and ginger creates a flavour base that makes less salt feel like enough |
| Use acid as a salt substitute | A squeeze of fresh lemon juice or a splash of raw mango (kachha aam) at the end of cooking creates the perception of saltiness and brightness without any sodium |
| Add salt at the end, not the beginning | Salt added after cooking sits on the surface of food where it hits the taste buds first, so less salt delivers more perceived saltiness |
| Use potassium-enriched salt (low-sodium salt) | Potassium chloride-based low-sodium salts (available in Indian pharmacies and health stores) replace 25 to 50% of sodium. Avoid in kidney disease; check with your doctor first |
| Toast and grind your own spices | Freshly toasted jeera, coriander, and garam masala deliver far more aromatic intensity than pre-ground versions, making food taste complete with less salt |
| Use amchur (dry mango powder) and tamarind | Both add a sour-savoury complexity that reduces the brain's craving for salt. Common in chaat masala, dal, and sabzi |
| Cook dal and rice without salt; season the dish | Boiling dal and rice in salted water wastes sodium. Add salt to the finished dish where it is more effective per milligram |
| Avoid packaged masala mixes | Pre-made sabzi masalas, biryani masalas, and chaat masalas are very high in salt. Make your own spice blends to control sodium content |
7-Day Low Sodium Indian Meal Plan
This meal plan targets under 1,800 mg of sodium per day, a meaningful reduction for most Indian adults with hypertension. No pickle, papad, or packaged seasoning is used. Salt is added sparingly only during cooking, not at the table.
| Day | Breakfast | Lunch | Dinner | Snack |
|---|---|---|---|---|
| Mon | Oats porridge with banana and walnuts (no salt) + 1 boiled egg + unsweetened green tea | 2 jowar rotis (minimal salt in dough) + moong dal (lightly salted) + palak sabzi + homemade unsalted dahi | Grilled mackerel with lemon and turmeric + brown rice (small, lightly salted) + lauki sabzi | Fresh fruit (apple or guava) + unsalted walnuts |
| Tue | Moong dal chilla (no added salt, flavoured with ginger + jeera) + mint chutney (lemon, not salt) + unsalted chaas | Brown rice + masoor dal (lightly salted, strong tadka) + bhindi sabzi + cucumber salad with lemon | Rajma (home-cooked, half the usual salt) + 2 bajra rotis + steamed broccoli with garlic | Unsalted roasted chana + 1 orange |
| Wed | Vegetable daliya with turmeric, cumin, and fresh coriander (minimal salt) + homemade dahi | 2 whole wheat rotis + chana dal with strong ginger-garlic tadka + methi sabzi + salad with amchur dressing | Rohu fish curry (mustard oil, light salt) + 1 roti + stir-fried cabbage with mustard seeds | Unsalted almonds (10) + papaya |
| Thu | Idli (2, home-made, minimal salt in batter) + low-sodium sambar (no papad) + coconut-free green chutney | Moong dal khichdi (lightly salted, strong tempering) + mixed vegetable curry + homemade unsalted dahi | Grilled chicken breast (marinated in lemon, turmeric, ginger; no salt marinades) + 2 rotis + sauteed spinach with garlic | Unsalted makhana (roasted with turmeric) + 1 guava |
| Fri | Ragi dosa (minimal salt in batter) + fresh tomato-coriander chutney (lemon-based, no added salt) + unsalted chaas | 2 bajra rotis + dal fry (lightly salted, strong tadka with curry leaves) + seasonal sabzi + salad | Paneer bhurji (home-made, minimal salt; fresh tomatoes, capsicum, ginger) + 1 roti + beetroot sabzi | Fresh pomegranate + unsalted cashews (small handful) |
| Sat | Besan chilla (lightly salted, with grated carrot and coriander) + low-fat dahi + banana | Vegetable brown rice pulao (minimal salt, whole spices for flavour) + home-cooked rajma + cucumber raita (unsalted dahi) | Sardines or mackerel curry (light, lemon-forward) + 1 roti + methi-aloo sabzi (half the usual salt) | Unsalted roasted peanuts + 1 apple |
| Sun | Poha with peas, curry leaves, mustard seeds, turmeric (minimal salt, lemon squeezed over) + green tea | 2 jowar rotis + toor dal (lightly salted, tamarind for sourness instead of extra salt) + seasonal sabzi + salad | Grilled salmon or tofu (lemon-turmeric marinade) + quinoa or brown rice + stir-fried mixed vegetables with ginger | Unsalted chaas + fresh fruit |
| Estimated sodium per day on this plan: 1,400 to 1,800 mg, down from the Indian average of 3,200 to 4,400 mg. The reduction comes primarily from: no pickle or papad, minimal salt in cooking (1/4 to 1/2 tsp per meal rather than 1 to 2 tsp), no packaged or processed foods, and using lemon juice, tamarind, and spices to provide flavour in place of salt. |

How to Read Food Labels for Sodium
Packaged food labels in India now carry nutritional information per 100 g and per serving. Here is how to use them to manage your sodium intake:
| Sodium per 100 g | Rating | What to Do |
|---|---|---|
| Less than 120 mg | Low sodium | Safe to include; check serving size |
| 120 to 400 mg | Moderate | Use in small portions; account for total daily intake |
| 400 to 600 mg | High | Limit significantly; look for lower-sodium alternatives |
| More than 600 mg | Very high | Avoid or treat as an occasional item only |
Watch for these terms on labels: sodium chloride (table salt), monosodium glutamate (MSG, common in Chinese and packaged foods), sodium bicarbonate (baking soda, used in breads and snacks), sodium benzoate (preservative in pickles and sauces), and disodium phosphate (stabiliser in processed cheese and instant noodles). All of these contribute to your daily sodium total.
Low Sodium Diet and Blood Pressure: What to Expect
Blood pressure responds to sodium reduction faster than most dietary changes. Research consistently shows measurable reductions within 1 to 2 weeks of meaningful sodium restriction. [1]
The magnitude of the response depends on your baseline intake and your individual salt sensitivity:
| Profile | Expected Systolic BP Reduction | Timeframe |
|---|---|---|
| Salt-sensitive hypertension (very common in Indians) | 8 to 12 mmHg | 2 to 4 weeks |
| General hypertension | 4 to 6 mmHg | 2 to 6 weeks |
| High-normal blood pressure (pre-hypertension) | 2 to 4 mmHg | 4 to 8 weeks |
| Normal blood pressure (preventive) | 1 to 2 mmHg | Ongoing benefit |
Salt sensitivity is particularly prevalent in South Asians, older adults, people with diabetes, and those with chronic kidney disease. [3]
If you fall into any of these categories, sodium reduction is likely to produce a larger blood pressure response than the average figures suggest.
For the best blood pressure outcomes, combine sodium reduction with increased potassium intake (from vegetables, legumes, and fruits), which counteracts sodium's effects on blood pressure through a complementary mechanism.
The DASH diet, which combines low sodium with high potassium, magnesium, and calcium, produces the largest blood pressure reductions of any dietary pattern studied. [4]
Low Sodium Diet with Hint
Tracking sodium is harder than tracking calories because it requires knowing the sodium content of every ingredient, including how much salt was added during cooking. Most people significantly underestimate how much sodium they consume. Hint takes the guesswork out of this.
Hint Premium: Your Personal Dietitian for a Low Sodium Plan
Managing a low-sodium diet around Indian food requires more than a generic food list.
It requires understanding which of your current meals are the highest sodium offenders, how to adapt your specific recipes, and how to hit your potassium and magnesium targets at the same time.
Hint Premium gives you access to a dedicated registered dietitian who will:
- Analyse your current diet and identify your top sodium sources so you know exactly where to reduce first
- Build a personalised low-sodium meal plan around your regional Indian food preferences, dietary type, and health conditions
- Teach you how to season and cook low-sodium meals that still taste satisfying, using Indian spices and cooking techniques
- Coordinate your sodium targets with your potassium, magnesium, and fibre goals for maximum blood pressure benefit
- Adjust your plan as your blood pressure responds, ensuring you are on the right trajectory
| Why personalised guidance matters for sodium: Everyone's salt sensitivity is different. A dietitian can identify whether you are a high responder (where sodium reduction alone could reduce your need for medication) or a moderate responder (where sodium reduction is one of several levers to pull). This distinction changes the priority and intensity of the dietary intervention significantly. |

Frequently Asked Questions
Is sendha namak (rock salt) better than regular salt for blood pressure?
No. Sendha namak has the same sodium content as regular table salt, approximately 38% sodium by weight. It contains trace minerals that table salt lacks, but the quantities are too small to provide any meaningful health benefit.
For blood pressure management, the total amount of sodium consumed matters far more than the type of salt used. Using sendha namak in the same quantities as regular salt provides no blood pressure advantage.
Can I use potassium salt (lo-salt) instead of regular salt?
Potassium chloride-based salt substitutes replace 25 to 50% of sodium chloride with potassium chloride, reducing sodium content by a similar proportion. They are a useful tool for people with hypertension and are available at pharmacies and health food stores in India.
However, they must be avoided by people with kidney disease or those taking potassium-sparing medications, as excess potassium can be dangerous in these conditions. Always consult your doctor before switching.
How much salt can I have per day with high blood pressure?
The American Heart Association recommends no more than 1,500 mg of sodium per day for people with hypertension, which equals about 3/4 of a teaspoon of table salt.
This includes all sodium from all sources, including cooking salt, packaged foods, pickles, papad, and restaurant meals.
For most Indians currently consuming 3,000 to 4,000 mg per day, even reducing to 2,000 mg (1 teaspoon) produces a significant blood pressure benefit. [1]
Does reducing salt work as well as blood pressure medication?
For mild to moderate hypertension, sodium reduction can produce blood pressure reductions comparable to a single antihypertensive medication, particularly in salt-sensitive individuals.
The DASH-Sodium trial showed reductions of up to 8.9 mmHg systolic through diet alone. [4]
However, for moderate to severe hypertension, medication is typically required alongside dietary change rather than instead of it. Never stop or reduce blood pressure medication without consulting your doctor.
What happens if I eat too little sodium?
Very low sodium intake (below 500 mg per day) can cause hyponatraemia (low blood sodium), particularly in people who sweat heavily, have certain medical conditions, or take diuretic medications.
For the vast majority of people following a low-sodium diet for blood pressure management, the target of 1,500 to 2,000 mg per day is well above the threshold for deficiency. The greater risk for most Indians is consuming too much sodium, not too little.
Does cooking method affect sodium content?
Yes. Boiling vegetables in heavily salted water increases their sodium content. Steaming, roasting, or stir-frying with minimal added salt keeps sodium lower. Rinsing canned legumes (if using canned dal or beans) reduces their sodium content by 30 to 40%.
Home-cooking from scratch, without packaged masala mixes or commercial sauces, gives you complete control over the sodium in every meal.
