Systematic Review Reveals Why That Morning Glass of Fruit Juice May Do More Harm Than Good
A new study led by Brigham Young University (BYU) in collaboration with German research institutions has found that regular consumption of fruit juice may increase the risk of type 2 diabetes. Published in the journal JAMA Network Open, the large-scale meta-analysis concluded that each additional 230ml serving of fruit juice per day is associated with a 5% increased risk of developing type 2 diabetes. In contrast, natural sugars consumed through whole foods like fruits and dairy do not carry the same risk and may even be linked to a reduced risk of the disease.
The study analyzed data from more than 500,000 individuals across multiple countries to explore how different forms of sugar impact metabolic health. Researchers compared the effects of sugars consumed in beverages-both natural and added-to those found in whole foods. They discovered that sugar-sweetened beverages like soda had the highest impact, raising diabetes risk by 25% per 350ml serving. Fruit juice, often perceived as a healthier alternative, also contributed to an elevated risk, though to a lesser extent.
