• The Supreme Court of India lifted a stay on criminal proceedings against Nestle over the alleged presence of lead and MSG or monosodium glutamate in popular noodles.
• The apex court had allowed the case against Nestle to reopen after the Swiss food giant had admitted the presence of toxic ingredients in its noodles during a court hearing.
• However, the company has argued that the lead was within the permissible limit.

Analysis:

• According to the World Health Organisation (WHO), lead is a cumulative toxicant that affects multiple body systems, including your liver and kidneys in particular.
• It is especially harmful to infant and pregnant women as it can cause damage to the central nervous system in children.
• Since lead is a heavy metal it can get stored in the teeth and bones, where it accumulates over time. In pregnant women, prolonged exposure to lead can result in miscarriage, prematurity, low birth weight, etc.
• MSG, short for Monosodium glutamate, is an amino acid found in your body and most foods. It is a flavour enhancer commonly added to Chinese food, canned vegetables, soups, and processed meats.
• When consumed in excess, it can cause several health issues, including a headache, nausea, sweating, weakness, chest pain, tingling or burning in the face as well as neck and other areas. It is claimed that MSG can cause asthma and even brain damage.
• MSG may cause adverse symptoms in some people, including a condition called Chinese restaurant syndrome or MSG symptom complex.
• However, there is no definitive evidence that MSG is solely responsible for causing these symptoms. Moreover, several official sources, such as the FDA, classified MSG as a food ingredient that's ‘generally recognized as safe.’ However, the use of MSG remains to be controversial.
