We now live in a culture created to fear fats and to buy premium low calorie foods... But the truth is that these low calorie foods are not good for you and fats some of them are good for you. Take for instance the omega fats that help improve concentration and brain development. OUR SKIN ALSO IS MADE UP OF FATS AND OIL TOO. What fats are not good for your health are the trans and saturated fats which clog up arteries and can cause heart problems.
