Trans fats are basically of two types, firstly those found naturally in dairy and meat products. Secondly those that are industrially produced when liquid vegetable oils are partially hydrogenated by adding hydrogen atoms which turns them into semi-solid fats like vanaspati. Hydrogenated vegetable oils have a long shelf life so they are extensively used in a number of packaged foods, biscuits, snacks, baked foods, spreads, margarine and in fried foods.
Industrially produced trans fats are considered to be unhealthy as they tend to increase the risk of heart attacks, strokes, diabetes, and other diseases. Studies show that trans fats increase blood levels of LDL (bad) cholesterol and decrease blood levels of HDL (good) cholesterol. To reduce the risk of these diseases the FSSAI has now regularised the maximum limit of trans fat in partially hydrogenated oils and fats to 5 percent.
Since trans fats are harmful to health it is mandatory to label them by type, the source (like mustard or groundnut oil) and the quantity in which they are found in the product food. A number of processed food manufacturers have eliminated or reduced the use of edible hydrogenated oils in their foods and so they display the words ‘Trans Fat Free’ on their food label. However, it is possible that the ‘Trans Fat Free’ label is not wholly accurate as many a time the trans fat content is based on raw ingredients rather than on the finished product. Therefore, there is a need to test the finished product in a food testing laboratory to ascertain whether the food product is actually trans fat free.
According to the Food Safety and Standards (Packaging and Labelling) Regulations 2011
- A health claim of ‘trans fat free’ may be made where the trans fat is less than 0.2g per serving of food.
- A claim ‘saturated fat free’ may be made where the saturated fat does not exceed 0.1g per 100g or 100ml of food.
Health experts consider the ‘trans fat free’ label to be misleading because consumers are unaware that even if the label says ‘trans fat free’ it could contain up to 0.2g of trans fat per serving. If the consumer has three servings of that food in a day they would consume 0.6g of trans fat. Similarly if they also in the same day consumed various other foods that have the ‘trans fat free’ label they would end up consuming a lot of unhealthy trans fat daily.
Most consumers overlook reading the full food label which also lists ingredients in descending order of quantity. It is mandatory to list edible hydrogenated or edible partially hydrogenated oil in the food labels so if these are listed it means the foods contains trans fat. If hydrogenated or partially hydrogenated oils are listed early on the list and before polyunsaturated or monounsaturated oils then the product contains lots of trans fat. If the label lists unsaturated or monounsaturated oils, olive oil, or canola oil first, the fats will be less harmful. Of course a number of food manufacturers are trying their best to remain within the ‘Trans Fat Free’ FSSAI criteria and are switching their use of partially hydrogenated edible oil to palm oil which is trans fat free.
