Our results showed that sugar content declined from 2018 to 2020 among all menu items (per-item: −0.43 g/year, 95% CI −0.66 to –0.21). This reduction in sugar was evident in beverages, sandwiches and desserts. Among core menu items (N=1855), sugar content reduced significantly from 2018 to 2020 (per-item: −0.31 g/year, 95% CI −0.45 to –0.17), especially in beverages. Energy, salt and saturated fat content in menu items remained constant overall, in both all menu items and core menu items. Fewer food categories had significant changes in energy, sugar, salt and saturated fat content among core menu items than among all menu items.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>From 2018 to 2020, sugar content declined in restaurant menu items, which may reflect a response to the sugar reduction strategy and the effects of the soft drinks industry levy. In contrast, there was little change in other nutrients. Future policies addressing the overall nutritional quality of restaurant foods, rather than single nutrients, may help the restaurant sector move towards offering healthier foods.</jats:p></jats:sec>
