Background 
Despite national dietary guidelines, dairy intakes remain low in China, partially because of high  prevalence of lactose malabsorption(1) . The fibre intake adequacy is also low comparing to the  recommendation in China(2). Milk-N is a new range of fortified and non-fortified low-lactose/highfibre milk products. In this study we analysed the associations between consumption of Milk-N  products and nutritional status using diet modelling(3) . 
Methods 
We used data from China Health and Nutrition Survey-2011(4) , participants above 20y were included  in the analysis (n=12127, 47% men, 53% women). Nutrient intakes were estimated through 3 days  dietary record and household food inventory. Two diet scenarios were modelled: A) Adding a serving  (200ml) of generic milk or of Milk-N to participants not meeting the dairy recommendation, and B)  Substituting dairy food intakes with Milk-N in equivalent amount for dairy consuming participants.  Paired t-test and Pearson’s Chi-squared test were used to compare the amount of intake and  prevalence of nutrient intake adequacy between the two types of addition, and before and after the  substitution. 
Results 
Overall, 17.4% of participants consumed dairy foods with an average intake of 160.5g/day, among  those 81.2% consumed milk. Only 1.1% of the population met dairy intake recommendations. In the addition scenario, compared to the addition of generic milk, adding one serving of fortified or  non-fortified Milk-N increased fibre intake by 25-35% (from 17.6g/day to 22-23.8 g/day), leading to  increased fibre intake adequacy from 16.4% to 27.0-32.8%, i.e. 65-100% increase. Addition of  fortified Milk-N improved daily average intakes of calcium, iron, zinc, vitamins A and C by 27-31%,  9%, 8%, 13%, and 16%, respectively. Consequently, the proportion of the population with  inadequate intakes decreased (p<0.01) for generic milk vs fortified Milk-N as follows, for calcium  (66.3% vs. 23.4-29.6%), iron (5.5% vs. 2.2%), zinc (28.1% vs. 18.9%), vitamin A (61.7% vs. 52.7%) and  vitamin C (62.4% vs. 51.5%). In the substitution scenario, replacing current dairy food intake with fortified or non-fortified Milk-N  increased fibre intake by 20-27% (from 18.4 to 22.0-23.4g/day), leading to increased proportion of  dairy consumers with adequate fibre intake from 18.7% to 28.2-32.3%, i.e., 51-73% increase.  Substitution with fortified Milk-N improved intakes of calcium, iron, zinc, vitamins A and C by 23- 27%, 7%, 7%, 10%, and 12%, respectively. Consequently, the proportion of dairy consumers with  inadequate micronutrient intakes significantly decreased (p<0.01) for calcium (from 72.9% to 50.3- 53.3%), iron (from 7.5% to 4.7%), zinc (from 33.0% to 26.1%), vitamin A (from 56.9% to 47.4%), and  vitamin C (from 60.2% to 50.8%). 
Conclusion 
In addition to the reduced lactose that helps to address lactose malabsorption, consumption of any  Milk-N alternative could improve fibre intake, while fortified Milk-N could also contribute to  reducing micronutrient inadequacies in Chinese adults.

Unique to the new Congress (previously the Summer Conference) is that you will have greater opportunity to engage with more nutrition science than ever before. In 2024 the core programme will be delivered by the Irish Section of The Nutrition Society, supported by the Science Committee. The theme of these symposia will be ‘new data – focused approaches and challenges’. Outside of the core programme you will have the chance to hear the latest research from the Society’s partner organisations, universities, the private sector and more, on a diverse range of research.
