CCMA CH 4
CCMA CH 4 REVIEW (Nutrition - Fats/Lipids)
Term | Definition |
---|---|
fats/lipids | - highly concentrated source of energy the body can use as a backup for available glucose - made up of carbon, hydrogen, and oxygen with different arrangement than carbs - 1 gram = 9 calories |
contain fatty acids | chemically - distinction between fatty acids and the types of fat they form are complex dietary - important difference is the degree of saturation |
unsaturated fatty acids | - less dense and heavy - oils with less potential to raise cholesterol levels - (Monounsaturated) olive, canola, peanut - (Polyunsaturated) corn, sunflower, safflower |
trans fats | - used to preserve food products - byproduct of solidifying polyunsaturated oils (hydrogenation) - raises LDLs ("bad" fats) cholesterol levels |
saturated fats | - solid at room temperature - primarily from meat products, palm, and coconut oil - raises LDL levels - no cholesterol present |
fats/lipids functions pt. 1 | - essential for absorption of fat-soluble vitamins - provide structure for cell membranes - promote growth in children - maintain healthy skin |
fats/lipids functions pt. 2 | - assist with protein functions - help form various hormone-like substances to prevent blood clots and control - protection & insulation (stored fat) |
too little fat | vitamin deficiencies, fatigue, dry skin |
too much fat | heart disease, obesity |
MyPlate recommendations | minimize intake of saturated and trans fats - ex. whole-milk dairy, egg yolks, butter, cream, mayo, whole-milk cheeses, meat (red esp.), oil packed fish, shortening, lard, coconut/palm oils - look for products that say "no trans fats" |
