“It is highly recommended to not overdo vegetables while cooking or burn bread when put in toaster. The idea behind the same is to reduce the amount of compound acrylamide that is formed, which is a chemical that lives on food that contains starch, like breads and potatoes.
It’s yet to be scientifically proven that foods like these contain a chemical that are linked to cancer. It’s better to avoid cooking them at high temperatures as foods like these are not counted under the healthiest snacks available.”
There might be a health risk linked to burnt toast? In fact, The Food Standards Agency (FSA) in the UK had launched a campaign warning about cancer risks linked to eating burnt toast or any other foods that contained starch being cooked at high temperatures. Now, there is no scientific proof.
Now, as these foods are cooked for longer period, they may turn golden to brown and eventually black. In the process, they produce higher levels of acrylamide, which may further increase the risk of cancer as per the FSA campaign.
