"Sure," he saiD、"I won’t eat all this."Lunch RequirementsIs Ryan eating a healthy meal if he eats the school lunch School lunch supporters say "Yes." Recent studies show that a government-approved school lunch has more variety and is more nutritious (有营养的) than most lunches brought from home. It’s also lower in fat.The National School LunchAct requires that school lunches go along with theDietary Guidelines forAmericans developed by the government. Meals must contain a variety of foods with plenty of grains and at least one fruit or vegetable each day. Foods must not contain too much sugar or salt.
A、hot lunch can contain up to 30% fat, but not more than 10% of its calories (卡路里) should come from saturated (饱和的) fat. In an average week, you should get one-third of the daily RecommendedDietaryAllowances for protein, iron, calcium (钙), and vitamins
A、andC、from your school lunch.Dare toCompareLet’s compare Ryan’s and Tyler’s meals to sec which is healthier. Ryan’s hot lunch (without the cupcake from his friend) has 577 calories, 25 grams of total fat. and 12 grams of saturated fat. He had one serving of fruit, 26 grams of protein, and 483 milligrams of calcium.

He ate 21 grams of protein and 155 milligrams of calcium, but no fruits or vegetables. Tyler’s meal met the saturated fat guidelines, but had too much total fat.Tyler ate more calories and total fat than Ryan diD、Ryan ate more protein, calcium, and fruit than Tyler diD、Which meal would you say is the healthier choice à laCarte OptionsFederal standards and most school districts forbid selling food in the cafeteria that competes with the school lunch. Many programs do, however, offer à la carte choices for students who don’t want the hot meal. Foods sold à la carte separate from the main meal and are priced individually. These foods do not have to meet the same nutritional standards as the foods on the hot lunch menu. Neither do the foods sold at a snack-bar or those foods available elsewhere in the school.
A、study in one Texas school district compared the lunches of fourth graders who did not have food choices with those of fifth graders who could choose either a standard lunch or select from a snack-bar. The fourth graders ate 25% more fruits and vegetables than the fifth graders.Food sold as fund-raisers can also have an impact on school lunch. The money raised is important to provide needed funds for many after-class activities.But the meal’s overall nutritional quality usually goes down. Many of these foods are high in fat, sugar, or both, and often come in extralarge portions. Fundraisers rarely sell fruits and vegetables.Choosing WiselySchool food-service programs are trying to please students, and still offer quality, nutritious meals at low cost. That task isn’t easy. One school district in New York decided to do something about it.
A、student advisory board kept the food-service director up-to-date on what the kids wanteD、They also worked with school snack-bars to sell smaller servings of chips and c
