The Food Safety and Standards Authority of India is looking at reducing the permissible limit for trans fat in edible oils and spreads to 2% from 5%. The regulator had in 2015 lowered the permissible limit for trans fat in edible oils to 5% from 10%, and given edible oil processors time till Feb 27 this year to comply with the norm. Health experts, however, have been seeking zero tolerance for trans fat in edible oils and spreads, as it is linked to higher risk of heart disease. Many countries allow only up to 2% trans fat in food products. The general thinking is that trans fat below 5% is safe.
