Final answer:
Tony's diet should have less than 10% of total daily calories coming from sugar to comply with guidelines. Based on a 2,000 calorie diet, this would be less than 50 grams of sugar per day. Without exact sugar intake in grams, we cannot determine Tony's compliance but guidelines help estimate it.
Step-by-step explanation:
To evaluate whether Tony's diet complies with the acceptable macronutrient distribution range for sugar, we have to take into account the Atwater system for determining the calorie content from macronutrients. The system uses the average calories per gram of protein, carbohydrate, and fats. For carbohydrates (which includes sugars), the average is around 4 calories per gram.
While the provided information does not specify the exact percentage of calories from sugar in Tony's diet, we can apply general guidelines. According to Figure 1.8, up to 10% of daily calories should come from saturated fats and 20% from unsaturated fats. Since sugars are a type of carbohydrate, we should aim for them to be a minimal part of the overall carbohydrate intake.
The dietary guidelines suggest that added sugars should comprise less than 10% of total daily calories. If Tony's diet includes 2,000 calories, then the limit for sugar would be less than 200 calories per day, which translates to 50 grams of sugar (since 1 gram of sugar has 4 calories). This is below the provided 'less than 20g' for DOS, ensuring compliance with the standard if his sugar intake is within this range.
