Abstract
本研究目的為探討不同顏色蔬果的介入對健康成年女性體內抗氧化狀態的影響。本研究共招募了 28 位 20~30 歲健康女性,實驗期間受試者須攝取 4 階段飲食,在第 1 和第 3 階段,皆給予 5 份綠白色蔬果 (Green & White, GW diet) 做為對照飲食;而在第 2 和第 4 階段,分別給予 3 份紅紫色 (Red & Purple, RP diet) 蔬果及 3 份橘黃色 (Orange & Yellow, OY diet) 蔬果,並加上 2 份綠白色蔬菜,做為試驗飲食。每階段的飲食皆進行 2 週,整個試驗共為期 8 週。分析不同階段供應餐食中的抗氧化物質含量及總抗氧化能力,並於各階段飲食介入前後抽取受試者空腹血液,測其體內抗氧化物質、總抗氧化能力及氧化壓力相關指標等的改變量。結果顯示,餐食中以 GW-I、GW-II 及 OY 飲食組的水果有較高量的維生素 C;RP 飲食組有最高量的總多酚及總花青素,但各個餐食中的類胡蘿蔔素、β-胡蘿蔔素及總抗氧化能力皆無顯著差異。血漿中各生化數值的改變量部份,維生素 C 在攝食完 GW-I 飲食後顯著上升;總花青素及總抗氧化能力在攝食完 RP 飲食後顯著上升。而氧化壓力指標方面,各組間則無顯著差異。此外,受試者血漿中的總多酚及維生素 C 與血漿中總抗氧化能力呈顯著正相關,但與血漿中 PC (Protein carbonyl) 呈顯著負相關。在本研究達到每日 5 蔬果之飲食設計下,多攝取綠白色及橘黃色水果,可獲得較多量的維生素 C;而多攝取紅紫色蔬果則可獲得較多量的總多酚及總花青素,並以總多酚較能提升體內的總抗氧化能力,這些結果可提供民眾及消費者在選擇蔬菜水果時之參考。
