A recent study has raised concerns about the health benefits of fruit juice, especially regarding its potential role in increasing the risk of type 2 diabetes. The international research, published in Advances in Nutrition, found that consuming even 100% pure fruit juice is linked to a 5% higher risk of developing type 2 diabetes for every 8-ounce serving consumed daily. The study, conducted by researchers from Brigham Young University and Germany, involved data from 14 large cohort studies, tracking over 490,000 adults for more than a decade.
The study examined various sugar intake sources, including total sugar, fructose, sucrose, and sugar-sweetened beverages (SSBs), with fruit juice showing a notable link to diabetes risk. Although fruit juice posed a smaller risk than sugary sodas—where each serving increased risk by 25%—it was still considered harmful to metabolic health.
The core issue lies in how fruit juice affects blood sugar levels. Unlike whole fruits, which contain fiber that slows sugar absorption, fruit juice removes this fiber, delivering concentrated sugar quickly into the bloodstream. This rapid spike in glucose and insulin levels can strain the liver and reduce insulin sensitivity, increasing the likelihood of type 2 diabetes over time.
While fruit juice can be just as sugary as soft drinks, experts suggest healthier alternatives for those seeking hydration. Whole fruit smoothies, infused water with flavors like cucumber or berries, vegetable juices such as cucumber or spinach blends, and coconut water—all lower in sugar—are recommended.
Experts advise that while it’s not necessary to eliminate fruit juice entirely, it should be consumed sparingly, like a sweet treat rather than a regular part of one’s diet. If you choose to drink fruit juice, experts recommend limiting servings, pairing it with high-fiber foods, and opting for no-added-sugar varieties, ideally with pulp. Always remember, eating whole fruit is a healthier option than drinking its juice.
