This week on Ask a Teacher, we answer a question from Minnie in China. She says:
本周的《名师答疑》，我们回答来自中国米妮的问题。她说：
Hello dear VOA, I'm a fan from China. I'm confused about "nutrition" and "nutrient."
亲爱的美国之音，我是来自中国的粉丝。我对"nutrition"和"nutrient"很困惑。
Is there any difference between them? What do they each refer to?-Minnie, China
他们之间有什么区别吗？他们各自指的是什么？——米妮，中国
Hello Minnie,
你好米妮，
If you read a lot about healthy living, you probably come across the words "nutrient" and "nutrition" often.
如果你读了很多关于健康生活的书，你可能会经常遇到"nutrient"和"nutrition"这两个词。
The short answer to your question is that "nutrients" are specific while "nutrition" is much more general.
简短来回答你的问题，"nutrients"是特定的，而"nutrition"是更普遍的。
Think about it this way: Several nutrients together in your food make up your nutrition.
你可以这样想：你的食物中多种营养物质共同构成了你的营养。
However, one nutrient by itself is not nutrition.
然而，一种营养物质本身并不是营养。
Nutrients are the individual substances in food that humans and animals need to live and grow.
"Nutrients"是食物中人类和动物生存和生长所需要的个别物质。
Vitamins, minerals, proteins and carbohydrates are examples of nutrients.
维生素、矿物质、蛋白质和碳水化合物都是营养物质。
Nutrients are measurable.
营养物质是可衡量的。
For instance, if you read the packaging on a food product, you can see exactly which nutrients it contains, and in what amounts.
例如，如果你阅读食品的包装，你可以清楚地看到它含有哪些营养成分，以及含量。
Plants, too, need nutrients to live and grow.
植物也需要营养物质来生存和生长。
Plant nutrients are found in (or added to) soil.
植物的营养物质存在于(或添加到)土壤中。
The soil contains substances like phosphorus and nitrogen.
土壤中含有磷和氮等物质。
Nutrition is the process of eating the right kinds of nutrients over time in order to support growth and stay healthy.
"Nutrition"是为了支持生长和保持健康，在一段时间内摄入正确种类的营养物质的过程。
So it is a more general term for a person's overall food intake.
所以它是一个更普遍的术语，指的是一个人总的食物摄入量。
Nutrition is also the word for the study of nutrients in food, how the body uses them, and the relationship between diet and health.
Nutrition也指研究食物中的营养成分，人体如何利用它们，以及饮食与健康之间的关系。
Because people have different dietary needs, some might need more of some kind of nutrients, while others need less.
因为人们有不同的饮食需求，一些人可能需要更多的某种营养物质，而另一些人需要较少。
So, nutrition is measured differently than nutrients are.
所以，营养的测量方法和营养物质的测量是不同的。
Finding out whether someone is getting the right nutrition for their body involves examining a person's individual needs and diet over time.
要想知道一个人是否得到了适合自己身体的营养，就需要检查一个人的个人需求和长期饮食。
That's Ask a Teacher for this week.
