Blueberry nectar is the juice obtained from pressing the fruit by separating the pulp, to which only water and sugar are added to make the taste and texture more pleasant.
Nutritional characteristics of Blueberry Juice
The active ingredient in blueberry juice is antioxidants, the most commonly known being flavonoids, pro-anthocyanins type A, catechins, tannins, ascorbic acid (vitamin C), citric acid, malic acid, etc.
The scientific evidence obtained on the antioxidant potential of bilberry relates more to the action of type A pro-anthocyanins, which are the qualitative reference parameter.
Blueberry juice is mainly used as an antioxidant supplement or as a urinary antiseptic pseudo-pharmaceutical, i.e. one that slows down or prevents the growth of bacteria in the bladder or urinary tract (prevention of cystitis and adjuvant to drug treatment).
Blueberry juice has two properties that are useful in reducing microbial growth in the urinary tract:
– Acidifies the urine by significantly limiting the multiplication potential of Escherichia coli, a bacterial strain potentially responsible for these diseases.
– Inhibits bacterial adhesion to the surface (epithelial) cells of the urinary tract.
Antioxidant function of blueberry juice
As mentioned above, blueberry juice contains a pool of antioxidants that are very useful in reducing potentially harmful free radicals.
Studies have shown a reduction in the growth of cancer cells, suggesting a potential preventive function of blueberry juice against various types of cancer.
- Blueberry juice has no contraindications, nor do the antioxidants it contains.

A glass of blueberry juice a day can be a good compromise between the benefits and the intake of simple sugars: it can be included for example during breakfast, as a fresh drink to start the day, or as a mid-morning or mid-afternoon snack, possibly accompanied by a portion of dried fruit or a source of protein such as Greek yoghurt (especially if the snack coincides with post-workout).
