Cooking oil is very important to get a good taste. Is cooking with palm oil healthy?
Using palm oil for cooking is fine from a health perspective, but not from a sustainability perspective. Often rain forests are cleared to create new palm oil plantations, so palm oil is responsible for deforestation, forest fires and loss of habitat for animals. Even certified organic palm oil and palm oil with RSPO certification are not without these problems.
Other cooking oils like coconut oil or olive oil are a better choice, both from a health point of view (see this blog and this blog) as well as from a sustainability point of view (see this question).
