In a recent study, scientists found that ‘ultra-processed’ foods make up more than half of all calories consumed in the US diet and contribute nearly 90% of all added sugar intake.
Ultra-processed foods are formulations of several ingredients.
Besides salt, sugar, oils and fats, they include substances not generally used in cooking, such as flavorings, emulsifiers, and other additives designed to mimic the qualities of ‘real foods’.
Ultra-processed foods include mass-produced soft drinks; sweet or savory packaged snacks; confectionery and desserts; packaged baked goods; chicken/fish nuggets and other reconstituted meat products; instant noodles and soups.
In the study, the team used dietary data involving more than 9000 people from the 2009-10 National Health and Nutrition Examination Survey (NHANES).
They found ultra-processed foods made up over half of the total calorie intake (just under 60%) and contributed almost 90% of energy intake from added sugars.
Added sugars represented 1 in every 5 calories in the average ultra-processed food product—far higher than the calorie content of added sugars in processed foods and in unprocessed or minimally processed foods and processed culinary ingredients, including table sugar, combined.
A strong association emerged between the dietary content of ultra-processed foods and the overall dietary intake of added sugars.
Furthermore, the proportion of people exceeding the recommended upper limit of 10% of energy from added sugars was far higher when ultra-processed food consumption was high, rising to more than 80% among those who ate the most ultra-processed foods.
The team also found only those Americans whose ultra-processed food consumption was within the lowest 20% had an average daily added sugar intake that fell below the maximum recommended limit.
Several leading health bodies, including the World Health Organization, the Canadian Heart and Stroke Foundation, the American Heart Association, and the US Dietary Guidelines Advisory Committee have concluded that excess added sugar intake increases the risk not only of weight gain, but also of obesity and diabetes, which are associated with a heightened risk of cardiovascular disease, and tooth decay.
The team says cutting back on the consumption of ultra-processed foods could be an effective way of curbing excessive added sugar intake in the US.
