A recent study published in the journal Advances in Nutrition has found that consuming sugar through beverages, such as soda and fruit juice, may be more detrimental to health than eating sugar directly. Researchers analyzed data from over half a million people across multiple continents and discovered a consistent link between sugar consumption from these sources and an increased risk of developing type 2 diabetes.
The study, led by Karen Della Corte, found that for every additional serving of sugar-sweetened beverages consumed daily, the risk of developing type 2 diabetes increased by 25%. This association was observed even with just one daily serving. In contrast, consuming an additional 8-oz serving of fruit juice per day resulted in a smaller increase in risk, at 5%.
Interestingly, researchers found that dietary sugars consumed from nutrient-dense foods, such as whole fruits and dairy products, did not have the same negative impact on metabolic health. This is because these sugars are accompanied by beneficial nutrients like fiber, fats, and proteins.
The study highlights the importance of limiting liquid sugar consumption, particularly in beverages like soda and fruit juice, which can overwhelm liver metabolism and lead to insulin resistance. The researchers suggest that future dietary guidelines should consider the differential effects of sugar based on its source and form.
Overall, this study emphasizes the need for a more nuanced approach to sugar consumption, recognizing that not all sugar sources carry equal risk. By understanding these differences, individuals can make informed choices about their diet and reduce their risk of developing type 2 diabetes.
