Even with all this positive data, experts do not recommend unlimited pouring. WebMD’s “Are There Health Benefits to Drinking Orange Juice?” stresses moderation because orange juice is still a concentrated source of natural sugar and low in fibre compared to whole fruit. Most guidance suggests choosing 100% orange juice with no added sugar, keeping portions to about 120–150 ml per day for adults, and having it with meals rather than sipping constantly to protect teeth and manage blood sugar.
When it is treated as a small, intentional part of a diet rich in whole fruits, vegetables, fibre and protein, orange juice moves away from “guilty pleasure” territory. The emerging picture from clinical studies and nutrition reviews is that a modest daily glass of 100% orange juice can contribute vitamin C, antioxidants and some heart supportive flavonoids, without derailing health goals for most people.
