1. Nutrition: Fats & Cholesterol Chapter 10 Lesson 2 Pages 261-262

2. Fats & Cholesterol ■ Objective 1: Compare and contrast saturated, unsaturated and trans fatty acids ■ Objective 2: Understand cholesterol and the difference between HDL and LDL

3. Types of Fats ■ Classified as 2 types depending on their chemical composition ■ Saturated ■ Unsaturated ■ Most fats in foods are a mixture of both types ■ No more than 25-35% of your daily caloric intake should come from fat.

4. Saturated Fats ■ Saturated fats are mostly found in animal based foods. ■ Examples: Animal fats/tropical oils ■ Palm oil, Coconut oil ■ Beef, pork, egg yolks, and dairy foods are higher in saturated fat than chicken and fish. ■ High intake of saturated fat will increase bad cholesterol = increased risk of heart disease

5. Unsaturated Fats ■ Unsaturated fats are mainly found in vegetables oils, nuts and seeds. ■ Examples: Vegetable fats ■ Olive, canola, soybean, corn and cottonseed oils ■ Increase in unsaturated fats will Increase of good cholesterol = lower risk of heart disease

6. Trans-Fats/ Hydrogenated Oils ■ Trans fatty Acids ■ Trans fats (AKA partially hydrogenated oils) are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. ■ Trans fats give foods a desirable taste and texture. ■ Inexpensive to produce and lasts a long time Examples: ■ Fried Foods (Fries, Doughnuts, Chicken) ■ Baked Goods (Pie crust, cookies, crackers, margarine) ■ Decreases good cholesterol and increases bad cholesterol levels

7. Role of Fats ■ Adipose Tissue: Stored body fat. ■ Fats provide a concentrated form of energy. ■ They are also important to brain development, blood clotting, and controlling inflammation. ■ They also help maintain healthy skin and hair. ■ Fats are essential to transport vitamins, A,D,E, and K in your blood. ■ Fats add texture and flavor to foods ■ Help satisfy hunger longer than carbs and proteins ■ Insulation for the body.

8. Cholesterol ■ Cholesterol: A waxy lipid-like substance that circulates in blood. ■ Is needed to create cell walls, certain hormones, and vitamin D. ■ 2 major types ■ LDL- Low Density → “bad” ■ HDL- High Density → “good” ■ A high intake saturated fats and/or trans fats can lead to an increase in cholesterol and lead to a build up in the arteries.
