Not All Results Are Identical—but the Trend Is Clear
Not every study reports the same outcomes. Some analyses show reductions in low-density lipoprotein (LDL) cholesterol, while other lipid markers, such as triglycerides or HDL, may change little. Still, the overall pattern suggests meaningful benefits.
Supporting this, a study of 129 workers at an orange juice factory in Brazil found lower levels of apolipoprotein B (apo-B)—a marker closely linked to heart attack risk.

Taken together, the evidence challenges the idea that orange juice is simply “sugar in a glass.” While whole fruit remains the healthier option due to its fibre content, a modest daily serving of pure orange juice appears to offer cumulative health benefits.
These include reduced inflammation, improved blood vessel function, better metabolic control, and healthier cholesterol profiles. It’s a powerful reminder that everyday foods can influence our bodies in ways we are only beginning
