Fats: Fats, which have been vilified, are an essential ingredient in our diet.
Poly and monounsaturated fats must be included in your daily plan. A small amount of saturated fats are also needed (<20g).
Minimize saturated fats, maximize monounsaturated fats and polyunsaturated fats. Try to get good Essential Fatty Acids - Omega 3 and Omega 6's.
Good fats:Fish and fish oils - polyunsaturated, best source of Omega 3's - cold water fish tuna, salmon, cod
Flax seed - some Omega 3, good Omega 6
Olive Oil - mono unsaturated fat
Avocados - mono unsaturated fat
Nuts - mono unsaturated, poly unsaturated, and omega 6s best are walnuts and almonds
Bad fats:Saturated fats - from animal products (fatty beef, pork, milk, etc)
Hydrogenated and partially hydrogenated fats (trans fats - margarine and Crisco are trans fatty acids)
Most vegetable oil and corn oil (use canola oil if you must use oil, and use in moderation - try not to cook in oil if you can avoid it. If you cook with oil, use an oil with the appropriate smoke point).
Remember that fats are calorie rich containing 9 calories per gram compared to 4 calories per gram for carbohydrates and protein.
As a female runner you should try and get at least 1,600 calories per day, ideally more than 2,000.
Check your weight and waist size once or twice a month. If they increase then you may be eating too much.
I'm glad that you are enjoying running so much. Welcome!
