Hazardous chemicals in plastic containers can leach out to the bloodstream upon heating
New Delhi, May 09, 2018 : Food microwaved in plastic containers can put you at greater risk of infertility, diabetes, obesity, and cancer, as per recent studies. Heating plastic containers in the microwave releases 95% of all chemicals, which could lead to high blood pressure, affect fertility, and damage functioning of the brain. It is important, therefore, to try and minimize the use of plastic and pack food in glass containers.
The most hazardous chemicals in plastic containers are bisphenol A, commonly known as BPA, and phthalate. When ingested, they get into the bloodstream and may lead to a series of problems like infertility, hormonal changes, changes in gender traits and even different types of cancers.
Speaking about this, Padma Shri Awardee, Dr K K Aggarwal, President, Heart Care Foundation of India (HCFI), said, “When food is heated in plastic containers in a microwave, the heat transfers the chemicals in plastic very effectively into the food. Indirect consumption of these chemicals can wreak havoc on the system. BPA and phthalates are believed to be ‘endocrine disrupters’, substances that mimic human hormones, and not essentially healthy for the system. ‘Microwave-safe’ labelling on a container indicates that they won’t melt or break when heated. However, they do not guarantee safety for health.”
If microwaving food in plastics is unavoidable, then consider the recycling codes at the bottom of the container. These indicate the type of plastic used. It is better to avoid any that have the code 3 or 7.
Adding further, Dr Aggarwal, who is also the Group Editor of IJCP, said, “Endocrine disruptors are capable of interfering with the way our glands produce hormones that govern virtually everything our bodies do. This includes the way we reproduce, grow, sleep, heal, develop mentally and burn energy. They disrupt this system, and upon reaching the receptors, they either block or mimic the hormonal messages, triggering abnormal responses.”
HCFI tips for using the microwave.
- If you’re concerned about plastic wraps or containers in the microwave, transfer food to glass or ceramic containers labeled for use in microwave ovens.
- Don’t let plastic wrap touch food during microwaving because it may melt. Wax paper, kitchen parchment paper, white paper towels, or a domed container that fits over a plate or bowl are better alternatives.
- Most takeout containers, water bottles, and plastic tubs or jars made to hold margarine, yogurt, whipped topping, and foods such as cream cheese, mayonnaise, and mustard are not microwave-safe.
- Microwavable takeout dinner trays are formulated for one-time use only and will say so on the package.
- Old, scratched, or cracked containers, or those that have been microwaved many times, may leach out more plasticizers.
- Don’t microwave plastic storage bags or plastic bags from the grocery store.
- Before microwaving food, be sure to vent the container: leave the lid ajar, or lift the edge of the cover.
