现在不少人在购物时发现，很多食品的外包装上都标有"低GI"字样，而且种类琳琅满目。那么，这些包装上的低GI是什么意思呢？据了解，GI全称为血糖 生成指数，它反映了某种食物引起血糖升高的能力。依据中国营养学会2023年发布的《预包装食品血糖生成指数标示规范》，低GI食品是指产品含可利用 碳水化合物（糖、淀粉），且血糖生成指数小于等于55的食品。低GI的加工食品通过特殊配方与工艺设计，能减缓可利用碳水化合物消化吸收速率，避免 血糖剧烈波动，具备慢消化，慢升糖，饱腹感强等特征。 记者走进一家大型连锁食品超市，发现标有"低GI"标识的食品占据着显眼位置。低GI的麦片、蛋糕、饮料、休闲食品，甚至低GI大米、面条等产品多达数 十种。一款标注"低GI认证"的纯酸奶，四小盒的价格接近30元人民币，而相同规格的普通酸奶，价格仅十几元。 记者在某电商平台的搜索栏输入"低GI"，商家有的强调自己通过了低GI认证，有的标注自己的产品"零蔗糖、零色素、零反式脂肪酸"，还有的宣称自己的产 品"在控糖期也能随便吃"。 低GI食品受追捧 食用效果褒贬不一 在健康消费趋势的推动下，"控糖"成为不少人的生活关键词，"低GI"食品受到了很多消费者 ...

GI，即血糖生成指数，是衡量食物摄入后引起血糖升高速度和程度的指标。低GI食品通常指GI值低于 55的食物，这类食物消化吸收较慢，有助于维持血糖稳定。 近年来，低GI成为健康饮食领域的热门标签，从面包饮料到饼干谷物，商家纷纷以此吸引消费者。然 而，面对市面上各类低GI食品，许多人心存疑惑：它们究竟是控糖减重的"良方"，还是商家的营销噱 头？消费者又该如何正确选购低GI食品？为此，记者采访了相关专家。 低GI食品成为消费新选择 公共营养师章英英表示，低GI仅代表升糖速度慢，但不是一个"万能值"。一些食品通过添加脂肪、糖或 特殊加工方式也可以降低GI值，但这类食品的脂肪含量和热量往往都很高，不仅不利于血糖控制，长 期过量食用还会导致体重上升，增加心血管疾病风险。 如今，在健康消费理念的推动下，低GI食品市场正持续升温。 记者在不少商超里看到，低GI饼干、低GI吐司、低GI坚果等主打无糖、零卡、低脂"健康标签"的食 品，被悄然摆到货架的"C位"。而在电商平台，"孕妇控糖""糖友加餐""健康零嘴"等更是成为各类低GI 食品的宣传标语。 当前，不少消费者为了追求更健康的饮食方式，热衷于购买低GI食品。"家里父母血糖偏高 ...

Core Viewpoint - The popularity of "low GI" (glycemic index) foods is rising in the market, but many products labeled as such lack authoritative verification and may not deliver the expected health benefits [1][3]. Group 1: Market Trends - "Low GI" foods are increasingly marketed with health-related labels such as sugar-free, zero-calorie, and low-fat, but the lack of mandatory national standards raises concerns about their authenticity [1][3]. - Consumers are often misled by the marketing of "low GI" products, with many unable to verify the claims made by sellers [2][3]. Group 2: Consumer Experiences - A consumer reported receiving moldy "low GI" bread, highlighting the difficulty in determining the authenticity of such products purchased online [2]. - Many products on e-commerce platforms display "low GI" labels, but the methods of proving this claim vary significantly, leading to confusion among consumers [2][3]. Group 3: Certification and Standards - Current "low GI" food certifications in China are voluntary, with no unified national standards for labeling, allowing various institutions to create their own certification logos [3][4]. - The cost of obtaining a "low GI" certification can range from tens of thousands to over a hundred thousand yuan, indicating a commercial nature of these certifications [3][4]. Group 4: Scientific Validity - True "low GI" certification requires rigorous testing by qualified laboratories, following international standards, which many products do not meet [3][5]. - The GI value of foods can be influenced by multiple factors, and without proper certification, the claims of "low GI" may not be reliable [5][6]. Group 5: Nutritional Guidance - "Low GI" foods should not be equated with overall healthiness; a comprehensive approach to nutrition is necessary, considering factors like low salt, low sugar, and high dietary fiber [5][6]. - Recommendations for consumers include choosing whole grains, controlling total caloric intake, and maintaining a balanced diet to effectively manage blood sugar levels [6].

Group 1: Types of Biscuits - Common types of biscuits include chewy biscuits, crispy biscuits, fermented biscuits, wafer biscuits, and filled biscuits, each with distinct characteristics based on ingredients and preparation methods [5] - Chewy biscuits have a longer kneading time, more gluten, and less oil, resulting in a chewy texture [5] - Crispy biscuits typically have higher oil and sugar content, leading to a crumbly texture with visible air pockets [5] - Fermented biscuits, like soda biscuits, use yeast to create bubbles, resulting in a crispy texture with a unique aroma [5] - Wafer biscuits consist of thin layers baked with cream filling, producing a light and crunchy bite [5] - Filled biscuits have a richer flavor due to fillings like jam or cream, but consumers should be mindful of their calorie and fat content [5] Group 2: Biscuit Texture and Structure - The crumbliness of some biscuits is primarily due to high oil content, low water content, and a loose structure [6] - The use of butter or shortening in the dough prevents flour from absorbing water, resulting in a more fragile and crispy biscuit [6] - During baking, moisture evaporates, and the starch dries out, contributing to the crispiness similar to dehydrated snacks [6] - The steam generated during baking creates small air pockets, leading to a delicate structure that enhances the crispiness [6] Group 3: Biscuit Storage and Preservation - To maintain crispness, biscuits can be reheated in an oven or air fryer for about 5 minutes, which helps expel moisture [7] - Alternatively, biscuits can be lightly toasted in a pan without oil to remove moisture [7] - Proper storage involves sealing biscuits in airtight containers and controlling humidity and temperature, ideally below 25°C and at less than 50% humidity [15] - After opening, biscuits should be consumed quickly or can be frozen to extend shelf life [16] Group 4: Health Considerations - Certain biscuits, such as cookies, filled biscuits, and puff pastries, are more likely to contribute to weight gain due to high sugar and fat content [12] - Cookies can contain over 30% sugar and fat, making their caloric content significantly higher than that of steamed buns [12] - Filled biscuits may have fat content ranging from 20% to 30% due to added syrups and creams [12] - Low GI biscuits are made from whole grains and fibers, which digest slowly and are suitable for individuals managing blood sugar levels [14] - Consumers with specific dietary needs should focus on ingredient labels to choose lower sugar and fat options while controlling portion sizes [18]
