一篇英文对话围绕健康生活为主题
People are paying more and more attentions to healthy diet , so nutrition(营养学) is growing an important science . Do you have any nutrition knowledge ? How much do you know about good nutrition ? Let’s have a test by judging true or false on the following points.
1.People who don’t eat meat can stay healthy .
True . As long as people eat enough milk , eggs and meat alternates(替代品) ，they can get enough protein .
2.Food eaten between meals can be just as good for health as food eaten at regular meals.
Ture . Nutritional value depends on what types of food you eat , not when you eat them . Eating an egg or fruit between meals can contribute to a good diet .
3.Fresh vegetables are always more nutritious than canned vegetables .
False . The difference depends more on how vegetables are prepared than whether they are fresh or canned . Vegetables cooked in too much water can lost a great amount of vitamins .
4.Natural vitamins are better than synthetic(合成的) vitamins .
False . There is no difference . A vitamin has the same propetives(性质) and specific chemical structure whether made in a laboratory or taken from plant or animals parts .
5.Older people need the same amount of vitamins as younger people .
True . Although older people need fewer calories(卡路里) . Certain illnesses raise the requirements for some vitamin , but that is true for the young as well as the old .
6.Food grown in poor soil is lower in vitamins than food grown in rich soil .
False . The vitamin in our foods are made by the plants themselves . They don’t come from the soil . However , the minerals in a plant depend on the minerals in the soil .
If you have answered these questions correctly , you can say you know much about food and nutrition by today’s standards . But remember that it may change as new information develops .
