8 enero 2026

Nutrition has never been so present… nor so full of contradictions. In this context, 100% fruit juice has become one of the most questioned products, often without scientific basis.

The Fruit Juice Science Centre Report 2025, based on a survey of more than 8,000 Europeans and backed by recent scientific studies, provides clarity: 100% fruit juice, consumed in moderation, is a nutritional ally within a balanced diet.

Full Report

When misinformation generates rejection

According to the report, more than half of European consumers feel confused by contradictory messages about food. In the case of juice:

A 38% mistakenly believes it causes dangerous blood sugar spikes.
Almost 4 out of 10 people think it contains added sugar, which legislation expressly prohibits.
As a result, almost 30% avoid consuming it, missing out on a natural source of nutrients.

What does a glass of 100% fruit juice really provide?

A glass of 150 ml of 100% orange juice provides essential nutrients:

Vitamin C, covering more than 90% of the recommended daily intake.
Potassium, key for muscle function and blood pressure.
Polyphenols, bioactive compounds with benefits for cardiovascular, brain, and inflammatory health.

Far from being "empty calories," juice concentrates essential nutrients in an accessible format that is easy to integrate into the daily routine.

Sugar: natural is not the same as added

One of the most widespread myths is equating 100% fruit juice with soft drinks. Scientific evidence shows that:

Juice provides only between 1 and 2% of daily calories.
More than 80% of the total sugar in the diet comes from other foods and beverages.
Consumed in moderation, it is not associated with obesity or type 2 diabetes.

The sugar in juice is natural and comes with vitamins, minerals, and bioactive compounds, which clearly differentiates it from sugary drinks.

A real support for a balanced diet

Despite the WHO recommending consuming five daily servings of fruits and vegetables, most of the European population does not meet this goal. In this context, 100% fruit juice:

Can count as one serving of fruit.
Helps cover common deficits of vitamin C and potassium.
Promotes iron absorption when consumed with meals.

Not all juices are the same. The nutritional quality largely depends on how the fruit is juiced.

Advanced juicing technologies like Zumex allow:

Preserving sensitive nutrients.
Better extraction of natural polyphenols from the fruit.
Ensuring 100% fruit juice, without added sugars, safe and consistent in quality.

Returning to science to regain trust

The message of the Fruit Juice Science Centre Report 2025 is clear: the fear of 100% fruit juice has no scientific basis.

Consumed in moderation and within a balanced diet, juice provides essential nutrients and facilitates healthy habits. In an environment saturated with informational noise, the combination of science, fruit, and well-applied technology is the best guarantee of trust.
