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.

According to the passage, what is one distinctive structural feature of the 2025 dietary pyramid?
- A Whole grains are featured at the top to signal their nutritional superiority.
- B The pyramid assigns identical visual weight to every recommended food group.
- C Plant-based and animal-based foods are placed in two entirely separate sections.
- D All food categories are arranged side by side without any hierarchical distinction.
- E It is presented upside-down, giving the highest prominence to protein, dairy, and fats.

請觀察第一段最後兩句關於視覺輔助工具（visual aid）的描述。文中特別用了一個形容詞 'inverted' 來描述這個金字塔，這在物理形狀上意味著什麼樣的改變？此外，在這種特殊的結構下，哪幾類食物被放在了「最顯眼」的位置，而全穀物又被移到了什麼樣的位置呢？

精準的細節定位與關鍵字轉換
恭喜你精準地鎖定了文章的關鍵資訊！這道題目考驗的是對文本細節的捕捉與「同義替換」的理解能力。你在閱讀時一定有注意到第一段末尾提到的核心描述：視覺圖表這次採取了 "pyramid shape — this time inverted"（倒置的金字塔），且蛋白質、乳製品與健康脂肪佔據了 "most prominent position"（最顯眼的位置）。選項 (E) 使用的 "upside-down" 正是文中 "inverted" 的完美對應，這顯示你不但讀得細心，對於單字靈活轉換的敏銳度也很高。
