英検1級・健康的な食事の費用と負担の違い【SOFI 2026】独自24修正・4択12問

結論：英検1級でSOFI 2026などの国連の英文を読む際、食料が供給されていること・十分なカロリーがあること・健康的な食事を購入できることは異なると理解する必要があります。国連の2026年報告が示す費用と負担可能性の違いを、慶英会の独自24の誤答修正例、独自4択12問・全解答、重要語彙20表現で練習します。英作文や二次面接にも使える社会・経済の論理教材です。

一次情報：FAO｜The State of Food Security and Nutrition in the World 2026、WHO｜SOFI 2026（2026年7月21日公表）、UNICEF｜SOFI 2026。報告は2025年に約6億4,500万人が飢餓に直面、約26億9,000万人が健康的な食事を購入できなかったと推計しています。WHO/FAO等の統計対象年と公表年を区別してください。金額の「PPPドル」は購買力平価に基づく比較単位であり、個々の店の現金価格ではありません。本記事の英文例・問題は慶英会の独自制作で、実際の個別栄養指導ではありません。

SOFI2026の重要な指標｜同じ意味ではない

概念	意味	混同しないもの
Cost	健康的な食事を構成する食品の費用	世帯が実際に購入できるか
Affordability	所得などを踏まえて支出できるか	食品が店頭に存在するか
Hunger	飢餓に関する人口・状態の指標	健康的な食事の負担困難と同義ではない
PPP dollars	購買力平価調整済みの国際比較単位	すべての国の店頭の米ドル現金価格
Dietary diversity	食の多様性	カロリー供給総量だけの評価

慶英会独自24の論理修正例｜費用・所得・栄養・政策

費用と購入可能性｜独自4例

修正1

不適切な断定：Food is available, so every household can buy it.

改善した英文：Food may be available but unaffordable for households with limited resources.

解説：供給量と購買力を区別する。

修正2

不適切な断定：The price of a healthy diet is identical to its affordability.

改善した英文：A diet’s cost concerns its price, while affordability also depends on household resources.

解説：コストと所得に照らした負担能力の区別。

修正3

不適切な断定：If a diet becomes cheaper, everyone can immediately afford it.

改善した英文：Lower prices may improve affordability, but household budgets and other conditions still matter.

解説：値下げを全員の購入可能性へ一般化しない。

修正4

不適切な断定：A food market has enough products, proving there is no food insecurity.

改善した英文：Availability alone does not establish that all households have adequate access to nutritious food.

解説：店頭在庫と食料安全保障は別。

十分なカロリーと健康的な食事｜独自4例

修正5

不適切な断定：Enough calories guarantee access to a healthy diet.

改善した英文：Adequate dietary energy does not by itself ensure access to a diverse and nutritious diet.

解説：カロリーと食の多様性を区別。

修正6

不適切な断定：Cheap starchy foods mean nutritious diets are affordable.

改善した英文：The affordability of a varied diet also depends on the prices of other nutritious foods.

解説：安価な主食だけで全体を評価しない。

修正7

不適切な断定：An increase in food shipments proves improved nutrition.

改善した英文：Shipping volume describes supply activity, not necessarily dietary quality or household access.

解説：輸送量と栄養上の成果を区別。

修正8

不適切な断定：A household buys fewer vegetables, proving it dislikes them.

改善した英文：Lower purchases may reflect prices or access barriers rather than preferences alone.

解説：購入行動から嗜好を断定しない。

国連の報告年と統計対象年｜独自4例

修正9

不適切な断定：SOFI 2026’s hunger estimate necessarily refers to data collected only in 2026.

改善した英文：The report was released in 2026, but its estimate of 645 million people experiencing hunger refers to 2025.

解説：発行年と対象年を区別。

修正10

不適切な断定：The report says exactly 2.7 billion people are hungry.

改善した英文：The report estimates about 2.7 billion people unable to afford a healthy diet, a different indicator from hunger.

解説：健康的な食事の購入困難と飢餓指標を区別。

修正11

不適切な断定：The 4.28 PPP dollars figure is the cash price paid everywhere.

改善した英文：The 2025 global healthy-diet cost estimate uses purchasing power parity and is not a universal local cash price.

解説：購買力平価ドルと現地価格を混同しない。

修正12

不適切な断定：A global average describes every country and family.

改善した英文：Global figures summarize populations and can conceal regional and household differences.

解説：平均値と各地域の事情を区別。

食品の生産と流通費用｜独自4例

修正13

不適切な断定：More farm production always reduces retail prices.

改善した英文：Additional production may help, but logistics, processing and market conditions also influence retail costs.

解説：農場での生産以外の工程を考える。

修正14

不適切な断定：Vegetable supply is sufficient, so distribution cannot be a problem.

改善した英文：Perishable foods can face storage and transport constraints even when production is adequate.

解説：傷みやすい食品の物流条件を考慮。

修正15

不適切な断定：Cold storage immediately makes every diet affordable.

改善した英文：Improved storage may reduce some losses but does not guarantee affordability for all households.

解説：インフラ効果の限界。

修正16

不適切な断定：Wholesale food prices and household purchasing power are the same measure.

改善した英文：Wholesale prices describe a market stage, while purchasing power concerns household resources relative to prices.

解説：卸売価格と所得・購買力を区別。

政策の短期的な効果と長期的な効果｜独自4例

修正17

不適切な断定：Food vouchers repair every structural problem in food supply chains.

改善した英文：Targeted assistance may improve short-term access without fixing all structural costs.

解説：所得支援と物流改善は補完関係。

修正18

不適切な断定：A road improvement guarantees lower prices in every shop.

改善した英文：Better transport may reduce some costs, but retail outcomes require evidence.

解説：インフラ整備の効果を一律に断定しない。

修正19

不適切な断定：An expensive programme cannot have any useful effect.

改善した英文：Policy costs must be compared with credible benefits and practical alternatives.

解説：費用があることと無効性を混同しない。

修正20

不適切な断定：A short decline in food prices proves long-term affordability.

改善した英文：Temporary price changes do not automatically demonstrate sustained affordability.

解説：短期の価格変動と長期の成果を区別。

評価と説明責任｜独自4例

修正21

不適切な断定：A higher food-production total proves nutrition security improved.

改善した英文：Food quantity alone cannot establish access to safe, diverse and nutritious diets.

解説：生産量と栄養保障の指標を分ける。

修正22

不適切な断定：A program enrolled many households, so it achieved its goals.

改善した英文：Participation totals do not directly establish improved diet affordability or quality.

解説：対象数と実際の成果を区別。

修正23

不適切な断定：One region’s successful policy must work identically everywhere.

改善した英文：Policies need to reflect regional prices, infrastructure and household circumstances.

解説：地域ごとの条件を比較。

修正24

不適切な断定：The report’s figures will never change in future editions.

改善した英文：Statistical estimates can be updated as methods and data develop.

いいえ。2026年に公表された資料でも、2025年など別の年を対象にした統計や推計値が含まれます。
