Black Salt: Side Effects, Warnings & Safe Usage Tips

Black salt, or Kala Namak, is widely valued for its distinct flavour and digestive benefits. However, like any ingredient, excessive consumption can lead to health issues. Understanding who should limit or avoid it, and how to use it safely, can help you make more informed dietary choices. Read on to know more.

What is Black Salt?

Black salt is a type of rock salt that is commonly used in South Asian cooking. It has a sulphuric smell and is also chosen for its digestive properties. It contains sodium chloride, little iron, potassium, and magnesium. It also has some sulphur compounds that give it its distinct pungent odour.

Possible Side Effects

Generally, it is safe to use black salt in normal amounts. But, its overuse can cause:

1. High blood pressure

It has less sodium than regular salt. However, when you use it in larger quantities, it can raise your blood pressure. Monitoring your diet and overall health becomes more important as you age, and having the right health insurance support routine check-ups and early detection.

2. Kidney problems

High intake of black salt can affect the functioning of your kidneys. Besides, if you already have kidney stones, it can even worsen the condition.

3. Digestive issues

High amounts of black salt can irritate your stomach lining and lead to acidity and bloating.

4. Thyroid

Usually, black salt is not iodised. So, replacing black salt with regular salt can cause iodine deficiency. This may lead you to suffer from thyroid dysfunction.

5. Electrolyte imbalance

It can cause an imbalance in your body fluids. This may make you feel tired and get muscle cramps.

6. Weaken enamel

Low-quality black salt may have additives like fluorides and other chemicals. Excess fluoride may damage your tooth enamel. It can also weaken your bones.

Who Should Avoid It?

You should avoid black salt in case:

• If you already suffer from hypertension or heart disease.

• Diagnosed with kidney stones or other chronic kidney disease.

• People following a low-sodium diet can also avoid it.

• If you are a pregnant woman, advised by your doctor to limit salt.

• If you have frequent acidity or have gastric ulcers, it is better not to have black salt. It's also wise to stay informed about your overall digestive health, especially when considering long-term wellness for the whole family. In such cases, having family health insurance can help ensure timely consultations and appropriate care.

Safety Usage Tips

Here are some safety tips to keep in mind:

• Limit your consumption and use it as a seasoning only.

• Try not to use it on a daily basis.

• Use it along with herbs and spices to reduce the overall salt content.

Conclusion

Even though black salt gives your food a nice flavour, it comes with some side effects as well. It can do more harm than good for people who have pre-existing health concerns. But moderation is key for safe consumption, and it is best to take medical advice from a professional.

Having the right health insurance policy supports better health management by covering doctor visits, diagnostic tests, hospitalisation, and even dietary or specialist consultations. It also helps you stay prepared for unexpected medical expenses while promoting overall wellbeing.
