Intended Meaning

It may have happened to many of us that we have lost our loved ones due to cancer or other diseases. In the face of many diseases, we may not be able to do anything. However, in some of them, we can, such as avoiding eating foods that contain carcinogens. Additionally, healthy eating is challenging in the fast-paced digital age. We generally think that if we eat less fast food, we have a more healthy diet. But the reality of having a healthy diet is much more complicated. Most of the things we consider healthy contain preservatives, palm oil, etc., which affect our health in the long run, and we should be very aware.
