Sure, there are certain fats that you can afford to get rid of, but others such as polyunsaturated fats and monounsaturated fats are a necessity. These "good" fats, or essential fatty acids, can be found in goods such as fish, nuts, and certain oils like olive oil. These fats are proven to lower cholesterol, rather than their not so healthy friends saturated and trans, which tend to raise them. According to the American Heart Association, essential fatty acids support healthy cardiovascular, immune, and nervous systems of the body and aid in the repair of cell membranes. Deficiencies of these good fats are linked to many healthy conditions like different types of heart disease.
On another note, you shouldn't go home and head for the pantry to stuff your face full of fattening Twinkies because you read in a PE blog that fats are 100% okay. Just because your body needs some fats doesn't mean that it needs ALL fats. Fats that are found in processed foods are often synthesized and added into products to enhance flavor or increase shelf life. Trans and saturated fats are the fats that should be avoided. Although they are sometimes thought to be equally bad, saturated fats are slightly better than trans fats. Saturated fats are the fats that come from animals and animal products like their meats, milks, and cheeses. Trans fats on the other hand, are also extremely harmful but are believed to raise cholesterol levels more so than saturated fats. The total amount of at should be limited to 25-35% of total daily calorie intake. This may seem like a lot of fat, but also keep in mind that the percentage of saturated fats should be less than 7%, and trans fat should account for less than 1%. The percentage left should be the "good" fats, polyunsaturated and monounsaturated fats that cannot be synthesized by chemicals.
In any case, the rule of thumb and a good key to healthiness is moderation. Eating a few delicious Oreos once in a while is fine, just so long as "once in a while" doesn't happen to be 5 times a day, everyday. On the other side of the spectrum, you should never completely eliminate something from your diet either, because everything has a function in your body. You need fats just as much as you need any other nutrient, but they key is the right amount. SO before you fill your plate with the congealed goodness that is bacon, remember that there are other options for a health breakfast that tastes just as good without all the heart clogging Have you ever tried turkey bacon, or maybe even veggie bacon? Both provide that same crunch and same familiar breakfast without the coagulation! The importance of fat is often underestimated, but did you know that 2/3 of your brain is composed of (you guess it,) FATS!
