Every year on 17th May, World Hypertension Day raises awareness about a silent, deadly threat that affects millions globally: high blood pressure. In India, where food is as much about emotion as it is about nutrition, the role of sodium in our daily meals is under increasing scrutiny. As we observe World Hypertension Day 2025, it’s time to shine a light on how sodium subtly but steadily makes its way into our diets- and what we can do to manage it.
What Is Hypertension?
Hypertension, or high blood pressure, occurs when the force of blood against the walls of your arteries is consistently too high. Over time, this excess pressure can damage your blood vessels and vital organs, increasing the risk of heart disease, stroke, and kidney problems. Often called the “silent killer,” hypertension usually presents no symptoms until significant damage has already been done.
Why Is Excessive Sodium Bad for Health?
One of the key dietary factors linked to hypertension is excessive sodium intake. Sodium, primarily consumed through salt, plays a vital role in fluid balance and nerve function. However, too much of it causes the body to retain water, increasing blood volume and, consequently, blood pressure.
The World Health Organization recommends no more than 5 grams of salt per day (about 2,000 mg of sodium), but many Indians consume far more often without even realising it. This excess sodium intake, sustained over time, contributes not only to hypertension but also to increased risk of stroke, heart failure, and osteoporosis.
How Sodium Sneaks Into Everyday Indian Meals
We spoke with Dr. Anuja Agarwala, a former dietitian at AIIMS and vice president of the Indian Dietetic Association, who shared her insights on the stealthy presence of sodium in our daily diets.
“For many people, reducing sodium intake simply means using less salt while cooking. But that alone isn’t enough,” says Dr. Agarwala. “Restaurant meals and packaged foods often contain surprisingly high levels of sodium, and it’s easy to overlook the extra salt we habitually add while eating.”
From savoury snacks like bhujia and namkeen to seemingly innocent pickles and papads, sodium is omnipresent. Processed foods such as bread, biscuits, sauces, and ready-to-eat mixes can carry hefty sodium loads. Even our beloved street foods and festive dishes are often sodium-heavy, thanks to seasonings, preservatives, and garnishes.
