4、ing them, and youd be hard pressed to find something at the supermarket that does hot list its calories per serving somewhere on the package. But have you ever wondered what exactly a calorie is? What is a Calorie A caloric is a unit of energy. We tend to associate calories with food, but they apply
5、 to anything containing energy. For example, a gallon (about 4 liters) of gasoline contains about 31,000,000 calories. Specifically, a caloric is the amount of energy, or heat, it takes to raise the temperature of 1 gram of water 1 degree Celsius(1.8 degrees Fahrenheit). One caloric is equal to 4.18
6、4 joules(焦耳 ), a common unit of energy used in the physical sciences. Most of us think of calories in relation to food, as in “This can of soda has 200 calories.“ It turns out that the calories on a food package are actually kilocalories (1,000 calories=1 kilocalorie). The word is sometimes capitali
7、zed to show the difference, but usually not. A food calorie contains 4,184 joules. A can of soda containing 200 food calories contains 200,000 regular calories, or 200 kilocalories. A gallon of gasoline contains 31,000 kilocalories. The same applies to exercise when a fitness chart says you burn abo
8、ut 100 calories for every mile you jog, it means 100 kilocalories. For the duration of this article, when we say “calorie“, we mean “kilocalorie“. What Calories Do Human beings need energy to surviveto breathe, move, pump bloodand they acquire this energy from food. The number of calories in a food
9、is a measure of how much potential energy that food possesses. A gram of carbohydrates(碳水化合物 ) has 4 calories, a grain of protein has 4 calories, and a gram of fat has 9 calories. Foods are a compilation of these three building blocks. So if you know how many carbohydrates, fats and proteins are in
10、any given food, you know bow many calories, or how much energy, that food contains. If we look at the nutritional label on the back of a packet bf maple-and-brown-sugar oatmeal(麦片 ), we find that it has 160 calories. This means that if we were to pour this oatmeal into a dish, set the oatmeal on fir
11、e and get it to burn completely(which is actually pretty tricky), the reaction would produce 160 kilocalories (remember: food calories are kilocalories) enough energy to raise the temperature of 160 kilograms of water 1 degree Celsius. If we look closer at the nutritional label, we see that our oatm
12、eal has 2 grams of fat, 4 grams of protein and 32 grams of carbohydrates, producing a total of 162 calories(apparently, food manufacturers like to round down). Of these 162 calories, 18 come from fat(9cal2g), 16 come from protein(4cal4g) and 128 come from carbohydrates(4cal32g). Your Caloric Needs J
13、ust how many calories do our cells need to function well? The number is different for every person. You may notice on the nutritional labels of the foods you buy that the “percent daily values“ are based on a 2,000 calorie diet2,000 calories is a rough average of what a person. needs to eat in a day
14、, but your body might need more or less than 2,000 calories. Height, weight, gender, age and activity level all affect your caloric needs. There are three main factors involved in calculating how many calories your body needs per day: -Basal metabolic rate(基本新陈代谢率 ) -Physical activity -Thermic(热的 )
15、effect of food Your basal metabolic rate(BMR) is the amount of energy your body needs to function at rest. This accounts for about 60 to 70 percent of calories burned in a day and includes the energy required to keep the heart beating, the lungs breathing, the kidneys functioning and the body temper
16、ature stabilized. In general, men have a higher BMR than women. The second factor in the equation, physical activity, consumes the next highest number of calories. Physical activity includes everything from making your bed to jogging. Walking, lifting, bending, and just generally moving around burns
17、 calories, but the number of calories you burn in any given activity depends on your body weight. The thermic effect of food is the final addition to the number of calories your body burns. This is the amount of energy your body uses to digest the food you eat it takes energy to break food down to.
18、its basic elements in order to be used by the body. To calculate the number of calories you expend in this process, multiply the total number of calories you eat in a day by 0.10, or 10 percent. Calories, Fat and Exercise So what happens if you take in more or fewer calories than your body burns? Yo
19、u either gain or lose fat, respectively. An accumulation of 3,500 extra calories is stored by your body as 1 pound of fatfat is the bodys way of saving energy for a rainy day. If, on the other hand, you burn 3,500 more calories than you eat, whether by exercising more or eating less, your body conve
20、rts 1 pound of its stored fat into energy to make up for the deficit. One thing about exercise is that it raises your metabolic rate not 0nly while youre huffing and puffing(喘气 ) on the treadmill. Your metabolism takes a while to return to its normal pace. It continues to function at a higher level;
21、 your body burns an increased number of calories for about two hours after youve stopped exercising. Lots of people wonder if it matters where their calories come from. At its most basic, if we eat exactly the number of calories that we burn and if were only talking about weight, the answer is no a
22、calorie is a calorie. A protein calorie is no different from a fat calorie they are simply units of energy. As long as you burn what you eat, you will maintain your weight; and as long as you burn more than you eat, youll lose weight. But if were talking nutrition, it definitely matters where those
23、calories originate. Carbohydrates and proteins are healthier sources of calories than fats. Although our bodies do need a certain amount of fat to function properly an adequate supply of fat allows your body to absorb the vitamins you ingestan excess of fat can have serious health consequences. The
24、U.S. Food and Drug Administration recommends that a maximum of 30 percent of our daily calories come from fat. So, if you eat 2,000 calories a day, thats a maximum of 600 calories from fat, or 67 grams of fat, per day. However, many doctors and nutritionists now set the maximum number of fat calorie
25、s at 25 percent of our daily caloric intake. Thats 56 grams of fat per day for a 2,000 calorie diet. 2 A calorie is a unit of energy associates with anything containing energy except food. （ A） Y （ B） N （ C） NG 3 People tend to use calorie when referring to food kilocalorie. （ A） Y （ B） N （ C） NG 4
