sugar

Compared meaning: sugar or carbohydrate as food or energy source (noun).

比较义项：糖/碳水化合物（作为食物成分或能量来源）（名词）。

• sugar 本词

  A specific sweet substance added to food or drink for taste; concrete, everyday word used in cooking, tea, coffee contexts.

  一种加入食物或饮料中用于调味的具体甜味物质；是日常用词，常用于烹饪、茶、咖啡等语境。

  He takes his tea with milk but no sugar.

  他喝茶加牛奶但不加糖。

• carbohydrate

  A broad nutritional category including sugars and starches, discussed in scientific, dietary or medical contexts rather than everyday cooking.

  一个宽泛的营养学类别，包括糖类和淀粉，多用于科学、饮食或医学语境，而非日常烹饪。

  Her doctor advised her to reduce carbohydrate intake to manage her blood sugar.

  她的医生建议她减少碳水化合物的摄入以控制血糖。

Both words name substances in food that give energy. Sugar is a specific, everyday sweet substance. Carbohydrate is a broader, more scientific nutrition category that includes sugar and starch. This does not compare sugar's figurative meaning, like 'sweet talk'.

两者都指饮食中提供能量的甜味或能量物质，但 sugar 是具体、日常的物质，carbohydrate 是营养学上的宽泛类别，涵盖糖、淀粉等多种物质，语域更正式、更科学。这里不比较 sugar 的“蔗糖、白糖”以外的其他隐喻或比喻义（如“甜言蜜语”）。
