The recommended daily amount of sugar intake is 25 milligrams, or about 6 teaspoons, according to the World Health Organization. This amount applies to adults with normal body mass indexes.
Less than 10 percent of foods consumed each day should contain sugar, recommends the WHO. Sugar is not just in sweets; it is also in processed foods. A cup of apple sauce has about 23 grams of sugar, a serving of fruit drink has 18 to 36 grams of sugar and 1/2 cup of bottled pasta sauce has about 12 grams of sugar, according to WebMD. Consumers can monitor their sugar intake by reading the labels on foods and making smart choices.
