Oils and fats play an essential role in a healthy diet, and you should eat approximately 12 teaspoins in a day

It is false that oils and fats play an essential role in a healthy diet and you should eat approximately 12 teaspoons a day. Whereas the first part of this sentence is true, oils and fats are indeed important for our bodies as they give us strength and proteins, the other part is incorrect. 12 teaspoons are way too much for daily intake, you should take up to 6 teaspoons.
Hope this helps and have a wonderful day!

Blood transfusions were rarely done and often fatal; they were outlawed until the nineteenth century.
