Study Notes
Nutritional Functions of Fats
- Found in animal products (meats, high-fat dairy) and plant oils.
- Provides 9 calories per gram, over double that of carbohydrates or protein.
- Maintains body temperature, aids in fat-soluble vitamin transport (A, D, E, K), cushions organs, and is vital for cell membrane structure.
- Digestion mainly occurs in the small intestine; triglycerides break into monoglycerides and glycerol.
Impact of Fats on Health
- Contributes to satiety and flavor in food; may slow digestion leading to prolonged fullness.
- Deficiencies in fat-soluble vitamins are rare in the U.S., except for vitamin D.
- Recommendations state 20-35% of daily calories should come from fat; toddlers should aim for 30-40%.
- Excessive fat intake leads to weight gain due to high caloric density, similar to other macronutrients.
Types of Fats
- Saturated Fats: Solid at room temperature, linked to heart disease since the 1950s. Recommended intake is limited to 5-6% of total daily calories.
- Monounsaturated Fats: Found in olive oil, considered healthier. Substituting these for saturated fats can reduce mortality risk.
- Polyunsaturated Fats: Includes omega-3 and omega-6 fatty acids, with positive health benefits. Should constitute no more than 11% of total fat intake.
- Trans Fats: Artificially created and associated with adverse health effects, including increased LDL and decreased HDL cholesterol.
Cooking Techniques
- Adds flavor but can increase caloric intake significantly (e.g., deep frying).
- Alternatives include air frying, grilling, baking, or boiling which preserve health benefits.
- Lowering fat can be achieved by using pureed fruits in baking, or sautéing with healthier oils like olive oil.
Special Considerations
- Many face issues with fat overconsumption rather than deficiency, particularly in Western diets.
- Certain populations (e.g., post-gallbladder surgery patients) may need to limit fat intake.
- Replacing saturated fats with unsaturated fats and promoting whole foods is key to heart health, aligning with U.S. dietary guidelines.
