Description of diets in the 10-month randomised intervention period

	Sugar group	S&SE group
Sugar-containing products	<10 E% added sugar.	<10 E% added sugar and as little as possible.
S&SE products	Not allowed. Except for up to two pieces of sugar-free chewing gum per day.	Allowed. No restrictions on specific types of S&SEs.
Units	Consumption of a maximum number of units (corresponding to 9.5 E% added sugar) of sugar-containing products each day/week.	Unit calculation (corresponding to 9.5 E% added sugar in weight/volume) will guide the participant to ensure intake of <10 E% added sugar. As many sugar-containing products in the diet as possible should be replaced with S&SE-containing products. Ideally, the amount of S&SEs products corresponding to the maximal units from sugar-containing products should be consumed. However, if a participant experiences an adverse event, they are recommended to consume less than the calculated units and change to other S&SE products (eg, avoid sugar-alcohols).
Example	For a participant with an energy requirement of 9000 kJ/d, 9.5 E% from sugar corresponds to 50 gram added sugar=5 units. 5 units per day or 35 units per week is then the maximum allowed intake of added sugar for this participant.	For a participant with an energy requirement of 9000 kJ/d, 9.5 E% from sugar corresponds to 50 gram added sugar=5 units. Ideally, this participant should consume 5 units per day or 35 units per week of S&SE containing products. One unit is equivalent to 1 unit in the sugar group (in weight or volume).
