Health by Stealth: reformulation as a targeted approach to improve the nutritional quality and sustainability of ready meals within the UK.

88%的英国成年人食用方便食品，包括即食食品，据报道其市场价值为39亿英镑（《更好的饮食》，2020年）。尽管大流行期间购买量有所下降，但现在方便餐的购买量呈上升趋势（Randall， 2022年）。据报道，63%的英国成年人将即食餐视为外卖的替代品，食品通胀可能会进一步推动这一增长（英敏特，2022年）。然而，就营养和环境影响而言，这是一个未被充分探索的研究领域。

Convenience meals, including ready meals, are consumed by 88% of UK adults, with a reported market value of £3.9 billion (Eating Better, 2020). Despite a decline during the pandemic, the purchase of convenience meals is now in an upward trend (Randall, 2022). Reportedly 63% of UK adults view ready meals as a takeaway alternative, and food inflation could push further growth (Mintel, 2022). Yet this is an underexplored area of research in terms of the nutritional and environmental impact.
