Food industry led reformulation efforts have attempted to address the prevalence of obesity by modifying nutrient compositions in food products. This study explored progress in nutrient composition alterations in products in Irish supermarkets by comparing the nutrient labels of products sold in 2014 and 2017.
We conducted two supermarket audits in 2014 and 2017 to examine the changes in the nutrient profile of cereals, breads, spreads, unflavoured milks, yogurts and juices. Information on the nutrients of interest to the study (energy, protein, fat, carbohydrate, saturated fat, salt, sugar and some micronutrients) were extracted and stored in Microsoft Excel. The nutrient profile of each product was compared across the two timepoints. Our study shows that the mean level of sugars in cereals remains high and that the mean level of salt remains high in cereals, breads, and spreads.
In total, 143 products were directly compared (86 cereals, 26 breads, 17 spreads and 14 milks). Our study shows that the composition of salt and sugar in cereal, bread, spreads and milk has declined by 12 and 7%, respectively. Saturated fat has declined in cereals (7%), but has increased in breads (12%), spreads (1%), and milks (5%). Manufacturers increased the serving sizes in nine cereals and one milk.
From a population health perspective, the results are encouraging but care should be exercised by the food industry not to allow total fat and saturated fat levels to creep upwards. Further research and engagement of public health specialists and the food industry are needed.
食品行业主导的配方改革旨在通过改变食品产品的营养成分来解决肥胖问题。本研究通过比较 2014 年和 2017 年在爱尔兰超市销售的产品的营养标签,探讨了产品中营养成分变化的进展。
我们在 2014 年和 2017 年进行了两次超市审计,以检查谷物、面包、涂抹酱、无风味牛奶、酸奶和果汁的营养状况变化。提取并存储了研究中感兴趣的营养信息(能量、蛋白质、脂肪、碳水化合物、饱和脂肪、盐、糖和一些微量营养素)。比较了两个时间点的每个产品的营养状况。我们的研究表明,谷物中的糖含量仍然很高,谷物、面包和涂抹酱中的盐含量仍然很高。
共直接比较了 143 种产品(86 种谷物、26 种面包、17 种涂抹酱和 14 种牛奶)。我们的研究表明,谷物、面包、涂抹酱和牛奶中的盐和糖含量分别下降了 12%和 7%。谷物中的饱和脂肪减少了(7%),但面包(12%)、涂抹酱(1%)和牛奶(5%)中的饱和脂肪增加了。制造商增加了 9 种谷物和 1 种牛奶的食用份量。
从人群健康的角度来看,结果令人鼓舞,但食品行业应注意不要让总脂肪和饱和脂肪水平上升。需要进一步研究和公共卫生专家和食品行业的参与。
