___________________: The Preferred Body Fuel Carbohydrates game:

Carbohydrates: One of 6 essential nutrients and are your body's main source of energy - should be the bulk of your diet. Made up of carbon, hydrogen, and oxygen. Types: Monosaccharides (made of single sugar units) Sugars Glucose (blood sugar) Fructose (fruits and honey) Galactose – bonds with glucose (sugar in milk) Disaccharides (made up of 2 sugar units) Sugars Sucrose (table sugar) Maltose (found in some grains) Lactose (milk) Polysaccharides (made up of many sugar units) Starches (corn, potatoes, bread) Fibers (plant foods only)

Simple vs. complex carbs Monosaccharides and disaccharides are _________________ High in simple sugars Candy, syrups, soft drinks Polysaccharides are ______________ High in starch and fiber Breads, cereals, rice, pasta, and veggies

How your body uses carbs Eating carbs sets off a complex chain of events in your body Carbs must be in the form of _____________ for cells to use Digestive system breaks down poly and disaccharides into monosaccharides (glucose) When the amount of glucose in the blood rises, insulin is released from the pancreas – helps to lower blood glucose back to normal Body cells burn glucose for energy If the cells do not have immediate energy needs, excess glucose is converted to glycogen and stored (2/3 is stored in muscles as an energy source) The liver stores the rest, but can only store so much. Too much makes your liver convert the excess carbs into fat. Too little and the body breaks down protein and fats for energy

Hunger vs. Appetite Complex carbohydrates take longer to digest than simple CHO. This gives complex carbohydrates great satiety value. ______________ is the feeling of fullness after you have eaten food. If the sandwich you eat is higher in complex carbs, you are likely to feel fuller longer after eating vs. having a candy bar for lunch.

Functions Produce _________________ Provide 4 calories of energy per gram Body can use and store them efficiently When stored forms of carbs become depleted, you feel signs of fatigue Spare ________________ Body is less efficient in using proteins for energy Body should use proteins to build and maintain cell structures Eat adequate carbs so you spare proteins for more vital roles Break down ___________ When fats are not broken down completely, compounds called ketone bodies are formed Collect in bloodstream and make it more acidic than normal (can cause damage to cells and organs-ketosis). Breath smells of nail polish remover, nauseous and weak, coma, death

Functions cont’d. Provide ____________ in the diet Fiber is responsible – promotes normal digestion and helps intestinal muscles retain their tone Acts like a sponge and absorbs water Swells and makes you feel fuller Slows the rate at which the stomach empties 3 terms for fiber Dietary – nondigestible carbs - plant foods Functional – nondigestible carbs - added to processed foods to enhance health benefits i.e. cereals and grains Total – sum of dietary and functional fibers

Meeting your carbohydrate needs Dietary Guidelines recommend ___________% of total calories come from carbohydrates Rich sources of carbohydrates include: How much is a serving? – Supertracker printouts!

Meeting needs The typical diet in the U.S. fails to meet recommendations for carbs. Most Americans eat more carbs than recommended, but too many are _______________ carbohydrates. How does your diet compare? Which do you choose more often? Do you choose OR Do you choose

Sugars Simple carbohydrates (sugars) in foods can be divided into 2 categories: Sugars that occur naturally in foods, are generally accompanied by other nutrients Lactose in ______________ ________________ in fruits Sugars added to foods at the table or during processing AKA refined sugars, are separated from their natural sources for use as food additives Soft drinks Candy Cakes Processed foods (ketchup and cereal)

Sugars continued… Reduced fat and fat-free food products often contain much added sugar Consumers try limiting their calorie intake by buying reduced-fat and fat-free cookies, however these products often have as many calories as regular cookies. Results in weight gain instead of weight loss Hidden sugars: the-hidden-sources-of-sugar-in-our-diets/ the-hidden-sources-of-sugar-in-our-diets/

Starches _________________ source of fuel for your diet Body can burn them efficiently for energy Have a greater satiety value than simple sugars Many are also excellent sources of vitamins, minerals, and fiber Includes foods from the grain group, vegetable group and legumes

Fiber The DRI for year old females is 26 grams per day. The DRI for year old males is 38 grams per day. Based on intakes that have been shown to help protect against heart disease Most people need to double their current fiber intakes to meet these recommendations High fiber foods: FruitsGrains, cereal, pasta LegumesVegetables Raspberries – 8 g/cup Spaghetti, whole wheat – 6.3 g/cup Split peas – 16.3 g/cup Artichoke – 10.3 g/medium Pears – 5.5 g/medium Barley – 6 g/cupLentils – 15.6 g/cup Green peas 8.8 g/cup
