# Fruit juices – more like fruit or sugar-sweetened beverages? Report of a symposium sponsored by the Fruit Juice Science Centre at IUNS-ICN Paris

## TL;DR

This paper discusses how fruit juice, despite containing sugar, behaves differently from sugary drinks due to its natural fruit components.

## Contribution

The paper highlights the unique role of the fruit matrix in modulating health effects of fruit juice compared to sugar-sweetened beverages.

## Key findings

- Fruit juice contains polyphenols and micronutrients that may benefit vascular health.
- Fruit juice is metabolically distinct from sugar-sweetened beverages due to its fruit matrix.
- Epidemiological evidence links higher polyphenol intake with lower cardiovascular disease risk.

## Abstract

A sponsored symposium was held at the International Congress on Nutrition to discuss the role of the fruit matrix in modulating the impact of 100% fruit juice (FJ) on markers of glycaemic control and vascular health and to present two recent studies. Structural, nutrient, and non-nutrient components of FJ, which comprise the fruit matrix and include polyphenols, pectins, vitamins, and minerals, have been shown in previous studies to influence postprandial metabolic responses. While the free sugar content of FJ and sugar-sweetened beverages (SSBs) can be similar, the fruit matrix distinguishes FJ from SSBs, the latter typically lacking in micronutrients and containing added sugars. Epidemiological studies consistently report that higher polyphenol intakes are associated with a lower risk of CVD, while some randomised controlled trials on citrus juices (rich in the flavanone, hesperidin) find beneficial effects for vascular function and blood pressure. Other randomised controlled trials report that FJ has neutral effects on cardiometabolic markers, which may be due to intra-individual differences in the digestion and absorption of polyphenols. The symposium concluded that the benign influence of the fruit matrix justifies the categorisation of FJ as a type of processed fruit, and not an SSB, for public health and regulatory purposes.
