以具有全国代表性的英国成年人为样本，测试达到英国营养科学咨询委员会 (SACN) 建议的饮食是否与较高的货币成本相关。一项横断面研究，将国家饮食和营养调查 (NDNS) 中的 4 天饮食日记与市场研究公司的同期食品价格数据联系起来。饮食的货币成本根据其是否符合 SACN 的八项基于食物和营养的建议进行评估。针对潜在混杂因素调整的回归模型。主要结果指标是个人每天每 2000 kcal (8368 kJ) 的饮食成本。英国。 NDNS 于 2008 年至 2012 年间采样的成年人（n 2045）。在等能量基础上，符合水果和蔬菜、油性鱼类、非奶外源性糖、脂肪、饱和脂肪和盐建议的饮食估计要贵 3% 至 17%。符合红肉和加工肉类建议的饮食价格便宜 4%，而满足纤维建议的饮食则成本中性。实现多个目标也意味着更高的成本；平均而言，符合 6 个或更多 SACN 建议的饮食估计比不符合建议的等能量饮食贵 29%。食品成本可能是限制英国采用饮食建议的人口层面障碍。未来的研究应侧重于确定系统和个人层面的策略，使消费者能够在不增加食品成本的情况下获得饮食建议。这些策略可以提高人们对健康饮食的接受度。
To test whether diets achieving recommendations from the UK’s Scientific Advisory Committee on Nutrition (SACN) were associated with higher monetary costs in a nationally representative sample of UK adults. A cross-sectional study linking 4 d diet diaries in the National Diet and Nutrition Survey (NDNS) to contemporaneous food price data from a market research firm. The monetary cost of diets was assessed in relation to whether or not they met eight food- and nutrient-based recommendations from SACN. Regression models adjusted for potential confounding factors. The primary outcome measure was individual dietary cost per day and per 2000 kcal (8368 kJ). UK. Adults (n 2045) sampled between 2008 and 2012 in the NDNS. On an isoenergetic basis, diets that met the recommendations for fruit and vegetables, oily fish, non-milk extrinsic sugars, fat, saturated fat and salt were estimated to be between 3 and 17 % more expensive. Diets meeting the recommendation for red and processed meats were 4 % less expensive, while meeting the recommendation for fibre was cost-neutral. Meeting multiple targets was also associated with higher costs; on average, diets meeting six or more SACN recommendations were estimated to be 29 % more costly than isoenergetic diets that met no recommendations. Food costs may be a population-level barrier limiting the adoption of dietary recommendations in the UK. Future research should focus on identifying systems- and individual-level strategies to enable consumers achieve dietary recommendations without increasing food costs. Such strategies may improve the uptake of healthy eating in the population.
