The German Society for Nutrition warned against eating artificially-processed oils, which are found, for example, in prepared pizzas, burgers, and French fries, because of the health risks.

She explained that the industrially treated oils cause a high level of harmful cholesterol in the body, which raises the risk of developing inflammatory responses in the body.

Also, you should stay away from foods containing "nitrite", such as hot dogs and salami, because when heating, a carcinogen "nitrosamine" may arise.

Also, you should stay away from dyes found in cornflakes, for example, which may lead to concentration problems, learning difficulties, attention deficit and hyperactivity in children.
