Is Juice Good Or Bad For Your Health? Here’s What The Experts Think.

On many breakfast tables, a glass of natural juice has become synonymous with health. However, while drinking juice may seem like a harmless habit, specialists warn that its impact on the body is more complex than it appears.

The key is fiber. When consumed whole, it slows the absorption of sugars and provides satiety.

However, when you drink juice, the fiber disappears and the fruit’s natural sugar—fructose—quickly enters the bloodstream. According to data from the Mayo Clinic, a single glass can contain more than 20 grams of sugar, making it similar to a regular sugary drink.

Furthermore, juice doesn’t make you feel full. This explains why it’s easy to feel hungry soon after a glass of freshly squeezed orange juice. Added to this is the effect of acid and sugar on tooth enamel, which, without proper hygiene, can erode it over time.

A study conducted by Northwestern University found that just three days of a juice-based diet caused metabolic disturbances. In fact, research has linked frequent juice consumption in young children with obesity and dental problems.

Now, does this mean that drinking juice is harmful? Not necessarily. Experts agree that, as part of a balanced diet, a small glass (120–150 ml) can be a practical source of vitamins and minerals. The important thing is to avoid using it as a substitute for whole fruit or consuming it in excess.

There are also many so-called ” detox ” juices on the market, which claim to cleanse the body and eliminate toxins. However, scientific evidence contradicts these promises. Harvard University reminds us that the body already has its own detoxification system—the liver and kidneys—and that no juice can replace that function. The British Medical Association even warns that these practices can lead to intestinal and metabolic imbalances.

So, when is it a good idea to drink juice? Experts suggest pairing it with foods rich in fiber, protein, or fat to reduce the impact on blood glucose. Preparations with pulp or smoothies are healthier options because they retain some of the fruit’s fiber. And, when choosing processed juices, it’s recommended to check the label and make sure they’re “100% juice” with no added sugars.
