Managing High Blood Pressure Through Indian Diet: The Salt Truth

If you have been told you have high blood pressure, the first advice was almost certainly "cut your salt". That is right, but it is not the whole story. Indian food is seasoned at every stage, at home, in restaurants and in the packaged snacks many people buy to eat better, so cutting salt takes more than putting the shaker away. Other parts of your diet matter too.

High blood pressure is common among Indian adults, and surveys suggest many people who have it do not have it under control. Medicines prescribed by your doctor come first. Food works alongside them, not instead of them.

How Blood Pressure Works

Blood pressure is the force of blood against artery walls. The top number (systolic) is measured as the heart beats and the bottom number (diastolic) between beats. Your doctor will tell you what your target range is.

Sodium is one factor. It makes the body hold water, which raises pressure. The balance of sodium and potassium, body weight, stress, alcohol and the health of blood vessels all play a part. A useful diet looks at all of these and not only the salt.

Remember that sendha (rock salt) and black salt are still sodium, so use them sparingly too. Potassium based salt substitutes can lower sodium intake, but they are not suitable for everyone: if you have kidney disease or take certain blood pressure medicines, ask your doctor before using them.

Where the Salt Really Comes From

WHO recommends less than 5 g of salt a day, about a teaspoon. Surveys suggest the average Indian eats well above this. Most people underestimate their intake, because a lot of salt hides in food that does not taste very salty:

• Pickles (achaar). A spoonful can carry a large share of a day's sodium.
• Papad. Small and light, but salty.
• Namkeen, chakli and chips. Packaged snacks are seasoned heavily.
• Restaurant and street food. Salted at every step of cooking.
• Instant mixes, soups and noodles. The sodium is on the label, so read it.
• Bread and baked goods. Salt is used in the dough, and it adds up over a day.
• Sauces and pastes. Soy sauce, ketchup, chilli sauce and ready masala pastes.

The biggest gains usually come from pickles, papad, namkeen and how often you eat out, not from the pinch of salt in your dal.

Lower Salt Without Losing Flavour

Low-sodium salt, which swaps part of the sodium chloride for potassium chloride, can help. It tastes a little different. Important: it is not safe for everyone. People with kidney disease, and people taking ACE inhibitors, ARBs or potassium-sparing diuretics, can end up with too much potassium. Ask your doctor before using it.

Ways to season with less salt:

• Amchur (dry mango powder) and tamarind add sourness that replaces some of the salty edge
• Lemon juice squeezed over a finished dish sharpens flavour
• Fresh coriander, mint and curry leaves add aroma
• Roasted cumin, black pepper and coriander give depth

The DASH Pattern, Indian Style

DASH (Dietary Approaches to Stop Hypertension) is the best-studied eating pattern for blood pressure. It leans on vegetables, fruit, low-fat dairy, whole grains and legumes, and goes easy on salt and processed food. In trials it has lowered blood pressure noticeably, though results differ between people. It does not replace medicines.

Potassium

Potassium helps the body get rid of sodium. Foods that give you more of it: coconut water, banana, rajma and other legumes, spinach, boiled potato with skin, sweet potato and drumstick. Packaged coconut water can have added sodium, so check the label. If you have kidney disease or take certain blood pressure medicines, ask your doctor before increasing potassium.

Magnesium

Almonds, pumpkin seeds, whole grains such as bajra and ragi, and green leafy vegetables are all good sources. Eat them as food. Do not start a supplement without checking with your doctor.

Calcium

Low-fat dairy such as curd, chaas and toned milk is a practical source in most homes. Two servings a day is a common DASH suggestion.

Nitrate-rich vegetables

Beetroot, spinach and radish contain nitrates, which the body turns into nitric oxide that relaxes blood vessels. Small trials have found beetroot juice lowers blood pressure for a short time. Grated beetroot in salads, a home-made beetroot and carrot juice, or palak in dal are easy ways to include them.

Other Foods Worth Having

Garlic. Some trials suggest a modest effect on blood pressure. Add it to dal and sabzi.

Flaxseeds. Ground flaxseed in roti dough or curd adds fibre and omega-3. Early trials look promising, but the research is limited.

Hibiscus tea. Small trials show a modest drop in blood pressure. It can interact with some medicines, so check with your doctor if you take any.

Oats. The fibre helps with cholesterol and heart health in general. Oats poha or oats upma with vegetables is an easy breakfast.

A Sample Day

On waking: Warm water. Optional unsweetened hibiscus tea if your doctor is fine with it.

Breakfast: Oats poha with vegetables, coriander and lemon, with very little added salt. A banana or other fruit. Unsalted chaas.

Lunch: Two jowar or bajra rotis, palak dal seasoned with lemon or tamarind, beetroot and cucumber salad, a small bowl of low-fat curd. Skip papad and achaar.

Evening: Fresh coconut water and a small handful of almonds and walnuts.

Dinner: Two rotis or a small portion of brown rice, rajma or moong dal, a sabzi with garlic and little salt, and fruit.

The Short Version

Cut the hidden salt in pickles, papad, namkeen and restaurant food. Eat more vegetables, fruit, legumes and low-fat dairy. Keep taking the medicines your doctor prescribes and get your pressure checked regularly. A nutritionist can turn this into a plan that fits what your family cooks.

FAQ

How much salt should I eat a day with high blood pressure?

WHO advises less than 5 g of salt a day for adults. Your doctor may set a lower limit for you. Count the hidden salt in pickles, papad and packaged snacks, not only what you add at the table.

Is low-sodium salt safe?

Not for everyone. It contains potassium, which can be unsafe with kidney disease or with some blood pressure medicines. Ask your doctor first.

Can diet replace blood pressure medicine?

No. Diet supports treatment and may help lower your numbers, but do not stop or change medicines without your doctor.

Which Indian foods help most with blood pressure?

Vegetables, fruit, legumes, whole grains, curd and unsalted nuts fit the DASH pattern best. Cutting pickles, papad, namkeen and takeaway food usually makes the biggest difference.
