伦敦地铁里满是推广姜、姜黄和浆果“健康饮品”的广告，宣称能增强免疫力并带来营养好处。尽管研究显示，姜能抗恶心、姜黄中的姜黄素有助于降低胆固醇、浆果可改善记忆和肠道健康，这些成分确有裨益，但市售果汁浓缩饮的效果受到质疑。虽然浓缩饮品可能含有花青素等抗氧化剂，但加工过程中流失的纤维和果皮营养素对消化和防病至关重要。MOJU关于肠道微生物的小型研究显示益处有限，且高剂量摄入存在毒性风险。专家强调，完整水果含有更多纤维和抗氧化剂，健康价值更高。偶尔饮用果汁浓缩饮虽无害，但相比直接食用水果，不仅成本更高效果也逊色，完整水果才是更健康、更经济的选择。

London’s underground is awash with ads promoting ginger, turmeric, and berry-based "health shots" claiming immunity and nutritional benefits. While studies suggest ingredients like ginger (anti-nausea), turmeric (curcumin for cholesterol), and berries (improved memory, gut health) offer some merits, commercialized juice shots face scrutiny. Concentrated doses may deliver antioxidants like anthocyanins, but juicing strips fiber and skin nutrients critical for digestion and disease prevention. Small trials, such as MOJU’s gut-microbiome study, show limited benefits, yet high doses risk toxicity. Experts note whole fruits retain essential fibers and antioxidants, offering superior health value. While occasional juice shots pose minimal harm, they are costlier and less effective than consuming whole fruits, which remain the healthier, economical choice for nutrient intake.
