Referring to its research in 2012, CSE also said that it had found that Maggi instant noodles came with a high salt content and that a packet of noodle had around 3 gram of salt while the recommended salt intake per person per day is 6 gram.
"This means that if you eat a packet of these noodles, you will have to watch your salt intake very carefully through the rest of the day. Consumption of such ultra processed foods high in salt is associated with the increased risk of obesity and diabetes," said Amit Khurana, programme manager of CSE's food safety team.

After Uttar Pradesh, the probe into alleged lapses of food safety standards was expanded and Maggi noodle samples are being tested across the country.
CSE said that "unregulated advertising of junk food" targeted at children plays "crucial" role in building up their food preferences and they fall victim to such advertisements as they are not mature enough to make the right food choice.
