Added and Free Sugar Distinction / 添加糖与游离糖区分

Definition

The added and free sugar distinction separates sugars added during production, cooking, or consumption from the broader free-sugar category that also includes sugars naturally present in honey, syrups, fruit juice, and concentrated fruit juice.

Current Synthesis

The episode uses this distinction to prevent a common consumer mistake: treating “natural” or “not white sugar” as automatically low-risk. Added sugar includes sugar put into food by manufacturers, cooks, or consumers, including household cooking sugar, brown sugar, honey, and syrups. Free sugar is broader in the public-nutrition sense because juice, concentrated juice, honey, and syrup can deliver sugars outside the intact structure of whole fruit or whole food.

The practical point is not terminology for its own sake. People need to know where sugar comes from and what food structure it travels in. A whole apple, apple juice, honey-sweetened yogurt, syrup-flavored drink, and “no white sugar” product can create different intake and absorption patterns even when the label feels healthy.

Key Claims

• Added sugar covers sugars introduced by manufacturers, cooks, or consumers during processing, cooking, or eating.
• Free sugar includes added sugars plus sugars naturally present in honey, syrup, fruit juice, and concentrated juice.
• Natural source language does not eliminate sugar burden when the sugar is separated from whole-food structure.
• Public nutrition advice uses these categories to manage health risk, not just to name chemical molecules.
• The distinction supports practical label reading because sugar may appear as honey, syrup, concentrated juice, fruit puree, or other ingredients.

Evidence

• Added-sugar scope: VOL.215 低GI蜂蜜、零蔗糖、抗糖丸…？这届控糖人到底踩了多少坑？ft.「大食话」 defines added sugar as sugar introduced in food production, processing, cooking, or household use, including red sugar, honey, and syrup.
• Free-sugar scope: VOL.215 低GI蜂蜜、零蔗糖、抗糖丸…？这届控糖人到底踩了多少坑？ft.「大食话」 cites the WHO-style definition covering added monosaccharides and disaccharides plus sugars in honey, syrup, fruit juice, and concentrated juice.
• Natural-source caution: VOL.215 低GI蜂蜜、零蔗糖、抗糖丸…？这届控糖人到底踩了多少坑？ft.「大食话」 warns that apples, pears, honey, juice, and concentrated juice can still contribute sugar even when no white sugar appears.
• Risk-management use: VOL.215 低GI蜂蜜、零蔗糖、抗糖丸…？这届控糖人到底踩了多少坑？ft.「大食话」 says the categories are more useful as public nutrition and health-risk tools than as mere chemistry labels.

Counterevidence & Qualifications

The source does not quantify safe or unsafe intake thresholds for individual listeners. It also does not argue that whole fruits or all naturally sweet foods should be avoided; the distinction mainly targets sugar separated from intact food structure or added into everyday products.

What Changed

• Added a public-nutrition category distinction that supports the wiki’s sugar-control branch.
• Clarified why honey, syrup, juice, and concentrated juice can still matter even when marketed as natural.
