Hidden salt in packaged food proving to be a killer
The latest research from the George Institute for Global Health, Public Health Foundation of India and the Centre for Chronic Disease Control, India, highlights the high levels of salt in packaged food sold in India. The survey, which looked at 5796 packaged food products, revealed huge differences in the salt content of similar foods, with some containing almost 10 times more salt than others, and less than a quarter of products would meet the UK 2017 salt targets.
âThe high level of salt in processed food is a great public health concern, as we are noticing a shift in dietary habits towards more convenience foods.â said Dr. Vivekanand Jha, Executive Director, The George Institute for Global Health, India. The main problem caused by salt is high blood pressure which greatly increases the risk of stroke, heart attack and kidney failure. âThese are all now leading causes of death and disability in India,â he added.
The research looked at 9 main food categories which contribute salt to the diet in India, and revealed that many food groups contain excessively high levels of salt. In particular, cooking sauces, table sauces and spreads contained on average 5 and a half grams of salt per 100g, with some containing 10 times that amount and others with almost no salt at all. âThis is particularly alarming as sauces and spread are often added to meals, and with such high salt contents, it will add substantially more salt to the dietâ said Dr. Jha.
Similarly, papads, a popular meal accompaniment, contained up to as much as 5g salt/100g, whilst others contained no salt. âThese findings clearly illustrate that food manufacturers are able to produce these foods with much less saltâ said Clare Farrand, Senior Project Manager for salt reduction strategies, WHO Collaborating Centre for Salt reduction at The George Institute for Global Health, Sydney.
âIn view of this report and the change in dietary habits, there is an urgent need for the government of India to develop a clear set of criteria or targets to reduce the amount of salt added to food by the food industry.â She added. âThis research provides baseline data on the amount of salt in foods sold in India, which can be used to develop reformulation targets to reduce salt levels in food as part of a national salt reduction strategy and reduce the risk of stroke and heart disease related disease death in India.â
The World Health Organisation recommends all member states reduce mean population level salt intake by 30% by 2025. The WHO Collaborating Centre on population salt reduction at The George Institute for Global Health, Sydney has a remit to support countries to achieve these targets.
Further to this, the survey revealed that only a third of products had salt content on the nutrition label, making it impossible for Indians to know how much salt they would be eating, and make a healthier choice. Almost a quarter of products carried no nutritional details at all.
âWe think itâs important that Indian consumers can easily see whatâs in their food; there is a clear need for better food labellingâ said Dr. Prabhakaran from the Public Health Foundation of India and Centre for Chronic Disease Control, New Delhi. He noted that âIt currently isnât mandatory to display salt levels on food packaging but itâs certainly something we need to consider.â
Some products contain excessively high levels of salt; for example papads, a commonly consumed meal accompaniment in India have a mean sodium content of 1219mg/100g â with a range of 2-4000mg/100g. This illustrates that papads can be made with as little as 2mg of sodium/100g, 2000 times less sodium than the papad product with the highest sodium content.
Incomplete nutrition information makes it impossible for people to know what they are eating and hard to make a healthier choice. Absent nutrition information makes it difficult to monitor amounts of salt, fat and sugar in widely consumed food products, and hold the food industry to account to reduce the unnecessary amounts of salt, fat and sugar added to processed foods. The high level of salt in processed food is a great public health concern; salt increases blood pressure, and thereby the risk of developing cardiovascular disease, the biggest killer worldwide."
