The general wisdom for many years was that all fat should be avoided. Trans fat, saturated fat, unsaturated fat — just stay away from them all. Now however, scientists realize that fat— and how our bodies process it — is much more complex!
Fats – The Good, The Bad
Mono-unsaturated and polyunsaturated fats are “good fats” and that saturated fats can be consumed in moderation. Trans-fats, however, should be avoided altogether, as they are dangerous because they raise cholesterol levels. High levels of certain kinds of cholesterol, in particular low-density lipoprotein (LDL) cholesterol (the so-called “bad cholesterol”) increase your risk for heart disease and other health conditions. So manage your cholesterol levels wisely.
Fats that are liquid at room temperature, like olive oils, are a better choice than foods that are semi-solid, like butter or margarine.” The following tips will help you choose a diet rich in mono-unsaturated and polyunsaturated fats and low in trans-fat.
Mono-unsaturated fat (unsaturated fat):
Good sources of mono-unsaturated fat are canola and olive oils, most nuts, and avocados. Nuts are among the best sources of pre workout foods.
Tip: Spread avocado on a bagel instead of cream cheese. Use olive oil and garlic instead of whole milk and butter for a flavorful twist on mashed potatoes.
Poly-unsaturated fat (unsaturated fat):
There are two types of poly-unsaturated fat, omega-6 and omega-3 fats. Since most people get plenty of omega-6 fats in their diet from vegetable oils, so the primary concern is omega-3 fats. Good sources of omega-3 fats are fish (salmon and tuna), flaxseed, and walnuts.
Tip: Snack on a handful of walnuts, or add a tablespoon of ground flaxseed to your morning oatmeal or cereal. You can also add ground flaxseed when you are baking cookies or muffins for an omega boost.
Red meat, fatty meats like salami, dairy products such as cream and butter, and thicker vegetable oils like coconut, palm, and kernel oil are sources of saturated fats.
Tip: Enjoy a steak now and then, but try to limit saturated fats to 10 percent of your diet plan, at the most.
Made by adding hydrogen to vegetable oil, a process designed to extend the shelf life of packaged goods, trans fat is found in a wide range of packaged and processed foods, including bakery items, cookies, and crackers.
Tip: Current Food and Drug Administration guidelines allow manufacturers to say that their product is “trans-fat free” if it contains less than 0.5 grams of Trans fat per serving. Check the labels of processed food for “hydrogenated” or “partially hydrogenated” oils in the ingredients. These words signal that product may have up to 0.5 grams per serving. Eat a few servings, and this starts to add up.
The bottom line? Be an educated shopper: Know what to look for and the potential pitfalls. Try to do the majority of your shopping on the perimeter of the grocery store, limiting your trips down the inside aisles — where most of the trans-fat culprits reside. On the perimeter, you can focus on fresh and frozen fruits and vegetables, lean cuts of meat and fish, and whole grains fresh from the bakery. Add a little olive oil, and you’ll really be cooking!
