energy = ?
energy = calories
monosaccharides
building blocks for sugar; have only one molecule of sugar
disaccharides
combines 2 monosccharides
glycogen
quick energy reserve; when thse become full, it turns into body fat; stored in liver and muscles
Two types of CHOs
Simple and Complex Carbohydrates
What is the best source of energy for runners?
carbohydrates
? calories should come from complex CHOs
45-60%
Carbohydrates (CHO)
energy-giving nutrients made of sugars, starches, an fiber; represent body's primary source of energy (quick source of energy); 1gCHO = 4 Kilocal. of energy; 1kcals = 1000 calories
Hitting the Wall?
running out od CHOs
USDA
US Department of Agriculture
nutrient dense
foods that are high in nutients and the amount of energy it provides
Nutrition
the science/study of food and the ways in which the body uses food; the study of how ans why we make food choices; and the study of the nutrients food contains
Major forms of complex CHOs
Starches and Fiber
Complex CHOs
combination of long chains of saccharides; includes veggies, grains, beans, cereal, potatoes; contain vitamins, minerals, and provide energy
empty calories
sugars that are high in calories but have few nutrients
Lactose(di) = ?
galactose(mono) + glucose(mono)
Poor diet
a contributing factor in 4 out of 10 causes of death
6 Classes of essential nutrients in food include:
Carbohydrates, fats, protiens (these first 3 give energy), vitamins, minerals, water
Simple CHOs
(mostly bad; short chains of sugar units); sugars such as glucose, fructose, and galactose; as well as sucrose and lactose; includes table sugarm honey, candy, soda, fruit, and most dairy
individual should not comsume more than ? tspns of sugar a day
10 tspns
CHO Loading
helps maintain energy levels during endurance activities
the individual comsumes more than ? tspns of sugar a day
20 tspns
Maltose(di) = ?
glucose(mono) + glucose (mono)
Fiber
the indigetible portion of plat foods that binds to waterin the intestinal trace to help make stool softer allows it to move your bowels along; prevents colon cancer; provides NO ENERGY
Sucrose(di) = ?
fructose(mono) + glucose(mono)
Starches
stored the polysaccaride form of glycogen, which is the form CCHOs take on when you have eaten more CHOs then your body needs; in flours, bread, pasta, potatoes, rice, veggies, beans
