The 2025 Dietary Guidelines for Americans, released on January 7, introduced several notable changes. The updated document is considerably shorter than earlier versions, and its primary visual aid has shifted from the familiar plate-based model back to a pyramid shape — this time inverted. Under this revised framework, protein, dairy, and healthy fats occupy the most prominent position, while whole grains are placed at the narrowest point. Despite the administration's claim that the guidelines represent an unprecedented overhaul of federal nutrition policy, many nutrition scientists argue the core advice — emphasizing whole, nutrient-rich foods and limiting added sugars, sodium, and saturated fat — remains largely consistent with prior recommendations. Some experts worry that exaggerating the novelty of the guidelines may erode public confidence in nutrition science. Controversy surrounds both the content and the process. Alongside the updated guidelines, the government released a supplementary document called the Scientific Foundation, produced by a separate nine-member paid committee without public comment. This document criticized the original advisory committee for incorporating a health equity perspective. For the first time, children aged ten and under are advised to avoid added sugar entirely. Experts have identified several internal contradictions. While the guidelines retain the ten-percent limit on saturated fat, they simultaneously endorse full-fat dairy, red meat, and animal-derived cooking fats — a combination nutritionists say would inevitably exceed that threshold. The recommended daily protein intake also surpasses established scientific reference values without sufficient supporting evidence. Additionally, downplaying fortified grain products raises concerns about adequate folate intake, which is vital for preventing neural tube defects during pregnancy.

請試著觀察這篇文章的段落分配：除了第一段簡述了指南的變化外，剩下的二、三、四段，作者主要是在羅列新的食譜清單，還是在轉述各方專家對這些變化的「看法」與「擔憂」呢？

太棒了！你能精準捕捉到這篇文章的核心論點，展現了非常敏銳的閱讀理解能力。這道題目測試的是我們對「全文主旨」的掌握，而你成功避開了局部資訊的陷阱。
全球視野與批判性思維
這篇文章雖然以 2025 年美國膳食指南的發布為開端，但隨後的篇幅其實大量集中在各界專家的質疑與論戰（Controversy）。文章中提到專家擔心科學誠信受損、批評決策過程缺乏大眾參與，並指出指南內部存在營養學上的矛盾。因此，選項 (A) 的 「Reactions」（反應）與「Controversies」（爭議）完美地涵蓋了文章後半段的核心內容，而不僅僅是陳述指南本身的改動。
