India in grip of silent salt consumption epidemic: ICMR-NIE
NEW DELHI: Excessive salt consumption is fuelling a silent epidemic in India with people at increased risk of hypertension, stroke, heart disease, and kidney disorders, according to scientists from ICMR's National Institute of Epidemiology.
The scientists have initiated a community-led salt reduction study to address the issue and are focusing on low-sodium salt substitutes.
While the World Health Organisation recommends less than 5 grams of salt per person per day, studies show that urban Indians consume around 9.2 grams/day, and even in rural areas, it is around 5.6 grams/day - both higher than recommended. One promising tool in this effort is low-sodium salt substitutes -- blends where part of the sodium chloride is replaced with potassium or magnesium salts, Dr Sharan Murali, a senior scientist at National Institute of Epidemiology (NIE) and principal investigator of the study, said.
"Lesser sodium consumption helps reduce blood pressure and improves overall heart health, making low-sodium alternatives a meaningful switch, especially for those with hypertension," Dr Murali stated.
"Just switching to low-sodium salt can lower blood pressure by 7/4 mmHg on average, a small change with a big impact," Dr Murali said.
To tackle the issue of high salt consumption, the NIE has launched a three-year intervention project in Punjab and Telangana, supported by the Indian Council of Medical Research. The goal is to evaluate the effectiveness of structured salt reduction counselling in reducing blood pressure and sodium intake among individuals with hypertension, senior scientist at NIE, Dr Ganesh Kumar, who is also a part of the study, said.

Health ministry asks government departments to display details about oil, fats in snacks
The Union health ministry has urged all government departments, autonomous bodies and ministries to display details about how much oil, sugar and fats are present in snacks, including samosas and pakoras, in their cafeterias and meeting rooms to tackle obesity, The Hindu reported. In a letter on June 21, Union Health Secretary Punya Salila Srivastava said that 'we are proposing display of Sugar and Oil Boards initiative to promote healthier dietary habits in various settings', PTI reported. Srivastava said that the boards would serve as 'visual behavioural nudges in schools, offices, public institutions, etc. displaying key information about hidden fats and sugars in everyday foods'. The health secretary also urged them to print health messages on all official stationery, including letterheads, envelopes, notepads, folders and publications to reinforce daily reminders on fighting obesity. The letter asked the departments, ministries and autonomous bodies to provide healthier options, including fruits and vegetables, in their offices, while limiting the availability of sugary drinks and high-fat snacks, The Hindu reported. It further called for the promotion of physical activities such as the use of stairs, short exercise breaks and facilitating walking routes. Srivastava referred to a study published in The Lancet in March, which predicted that nearly 45 crore Indians could be overweight or obese by 2050. This would mean that India is likely to have the second-highest number of overweight and obese people in the world, after China. Obesity significantly increases the risk of non-communicable diseases such as diabetes, heart disease, kidney and liver problems, and certain cancers. It also affects mental health, mobility and quality of life. The campaign undertaken by the ministry will first be rolled out at the All India Institute of Medical Sciences in Nagpur, The Hindu reported. An unidentified ministry official told the newspaper that the campaign was expected to expand to other cities later this year.

How to raise healthier children: A roadmap from an Indian kitchen
India's rising economy is often seen as a symbol of progress, but when it comes to children's health, the picture is far from ideal. Behind the glossy surface lies a growing crisis: obesity, type 2 diabetes, early heart disease, poor gut health, hormonal imbalance and even insulin resistance are increasingly being seen in young Indians. And one key reason ties them all together -- FOOD IS MISSING FROM OUR CHILDREN'S PLATESIntegrative lifestyle expert Luke Coutinho believes the root of many childhood health issues lies in what's (not) on their plate. "We've spent years working with adults who are healing from what went unresolved in childhood—nutritionally, emotionally, physically. That's why I believe that the most impactful health interventions don't begin in hospitals or clinics alone. They begin in the kitchen. In school tiffins. On the family dining table," Coutinho tells India's rich supply of fruits, vegetables, grains, and spices, many children are growing up malnourished, overweight, or suffering from hidden metabolic issues. The gap between access and application is widening, and it's costing their health. India currently faces a triple burden of malnutrition, including undernutrition, micronutrient deficiencies, and overnutrition.

If we look deeper—in my practice, I see high blood glucose levels in kids as young as 9. Youngsters with fatty liver due to junk food. Girls hitting puberty too early, developing thyroid issues—all linked to hormonal disruptors in processed foods. Sadly, though India has natural fruits, vegetables, and grains, it's leading in disorders affecting kids. Almost ranking second globally among children with prediabetes, high cholesterol, or fatty liver.' Nutritionist and chronic disease specialist Deepta Nagpal highlights the power of food in fighting disease, when used correctly. () Coutinho points out how different regions of India already have time-tested, nutrient-rich traditional diets that are perfectly suited to local climates and children's needs. "From bajra khichdi in the North to rasam and idli in the South, and jowar bhakri in the West to kodo millet in Central India, every region has its own nutrient-rich, seasonal foods perfectly suited to local climates and growing children," he says.A BALANCED PLATE IS A POWERFUL TOOLNagpal breaks down how a simple home-cooked Indian thali can support immunity and development.'A plate of dal chawal, curd, pickle, and salad is a completely balanced meal. Dal chawal gives complete protein. Curd and pickle are probiotics that help digestion and gut health. Salad provides minerals and vitamins. And ghee offers butyric acid, which supports immunity," she adds, 'Local and seasonal foods aren't just tasty, they are biologically aligned with our bodies. Food is information to our genes. They grow in the same soil we live on, face the same climate we do, and carry the microbial and nutritional intelligence of the land we belong to.'advertisementWhen children eat local, seasonal foods, they build stronger internal systems that support digestion, energy, mood, and immunity.
