According to a recent study, shop bought orange juice contains same levels of bioactive compounds as freshly squeezed.
In fact, the research, published in the International Journal of Food Sciences and Nutrition, claims that shop bought orange juice delivers more than 90 percent of our vitamin C in one glass.
In recent years, some consumers have raised concerns that the manufacturing process destroys the nutritional value of shop bought 100 percent orange juice.
