People should not drink orange juice before meals, especially breakfast, according to experts from Princeton University.
Research published in the journal Cell Metabolism shows that orange juice contains a lot of fructose, a type of sugar found in fruit, which is harmful to the liver and intestines if consumed on an empty stomach.
According to experts, previously, the medical community believed that all sugar consumed, including fructose, was processed in the liver. However, new research shows that 90% of fructose is processed in the small intestine. Excess sugar can move to the large intestine, colon and harm this organ as well as the intestinal microflora. In contrast, when the stomach is full, the small intestine processes fructose more effectively.
Therefore, experts say that drinking fruit juice on an empty stomach, especially in the morning after a night without eating, can negatively affect health.
"The microbiome can't recognize sugar. As soon as you drink soda or juice, the microbiome senses an extremely powerful nutrient. Any amount of fructose that gets to the large intestine causes health problems," explains Joshua D. Rabinowitz, professor of the Lewis-Sigler Institute for Integrative Genomics at Princeton University.

In fact, previous studies have also shown that orange juice is not as healthy as people think. It contains nutrients such as carotenoids, flavonoids, vitamin C, which help fight oxidation, strengthen the immune system, and fight free radicals.
However, this drink can increase blood sugar, causing diabetes. According to Professor Scott Kahan, director of the National Center for Weight and Health, orange juice has as much sugar and calories as soft drinks.
“People with diabetes need to avoid drinking too much orange juice. Over time, spikes in blood sugar can lead to dangerous conditions like heart and kidney disease, even in people without diabetes,” says Kahan.
Orange juice can also cause weight gain. Some experts recommend that adults and children eat oranges instead of drinking juice. This is because fruit contains fiber, which slows digestion and makes people feel fuller for longer.
Previous studies have shown that drinking fruit juice, instead of eating it directly, can cause obesity and damage the liver. This is because when drinking juice, the body quickly consumes it without feeling full, loading a large amount of sugar into the body.
Some experts recommend drinking orange juice and other fruit juices mid-morning, after a full meal. However, it should be drunk about 45 minutes to an hour before meals.
