Nutritional information and benefits

The inherent qualities of Agen prunes have been appreciated since the Romans, and are an ideal part of any balanced, nutritious and delicious diet.

These prunes offer three main benefits: the quality of their sugars, the diversity of their vitamins and their mineral content.

A moderate glycaemic index

One prune will typically contain between 20 and 25kcal, with the vast majority of the energy from sugars.
It contains very little protein, and even less fat. These sugars are easily available for your body, but are released progressively. These qualities are highly prized by sportsmen and women who participate in high and medium intensity sports, thanks to the ideal balance of glucose, fructose and sorbitol; in other words, they offer the right balance of quickly and slowly assimilated sugars.
This balance gives prunes a moderate glycaemic index of 52.

Glucose is a monosaccharide which is assimilated extremely quickly, and is burned up by your metabolism. This is the standard “fuel” for your body’s cells.

Fructose is a monosaccharide which is characteristically found in fruit, and which affects your body’s glycaemic regulation. Once metabolised by the liver, it is transformed into glucose and can then be used to power your muscle contractions.

Sorbitol is not a sugar that is often found in plants (it takes its name from the French word for rowan). Agen prunes, with an average sorbitol content of 10g per 100g (sometimes ranging from 3g to 20g), are one of the fruits which contain the most. A polyol with a slightly different chemical structure to other sugars, sorbitol is not as sweet as glucose or fructose. It is only partially digested by your small intestine, and then only partially metabolised in your colon. It has only a minor effect on your blood sugar and insulin levels. Lastly, sorbitol acts as a stimulant for your gallbladder and your intestines.

A balanced source of fibre


Prunes contain a significant quantity of fibre (7g for 100g, on average). This includes two different types: soluble fibre (40-50%) and insoluble fibre (50-60%). Soluble fibre is easily assimilated by your body, and is what give prunes their tender, moist texture. It is great at retaining water, and has a gentle, beneficial effect on your intestinal tract. Insoluble fibre, however, plays a more “mechanical” role. It accelerates transit and stimulates the action of your intestines.

A cornucopia of vitamins and minerals


Agen prunes contain a vast array of different minerals (iron, magnesium, potassium, boron, etc.), vitamins and antioxidants (pro-vitamin A, vitamin E, etc.). Highly prized for their protective properties, they work to trap free radicals, which cause cellular degeneration.

The study undertaken by the team led by Professor R. PRIOR at the University of Tufts in Boston enabled them to develop the ORAC index (Oxygen Radical Absorbance Capacity), which lets them measure the free radical absorbance capacity of various fruits and vegetables, and measure them against one another.

Thanks to this research, we now know that prunes absorb more free radicals than any other fruit or vegetable.
