Should I drink fruit juice? Is it good for me?





Fruit juice is a favourite drink for many people. But is drinking fruit juice bad if you’re diabetic?


Fruit juice, for example orange juice, is high in sugar and is digested rapidly once consumed. Consuming too much fruit juice can cause a rapid increase to your blood glucose levels (also referred to as blood sugar levels), which may lead to hyperglycaemia. If you have diabetes, it is best to avoid drinking large quantities of fruit juice to avoid any rapid changes to blood glucose levels.

Carbohydrate content of fruit juice

A small glass or 125mL of fruit juice, contains 15g of carbohydrate or one portion. At home, we have so many different sized cups and glasses, with a standard cup holding approximately 250mL. This means, one 250mL glass of juice contains two carbohydrate portions!! If you’re consuming 2-3 glasses of juice a day, you could be having 4-6 portions of carbohydrates (60-90g of carbohydrates), just from juice alone. This amount of fruit juice could mean you’re easily going over your allowable carbohydrate portions for the day.


If you are already part of our program, we have covered carbohydrate portions in more detail in Week 4. You can learn more about carbohydrate counting and how many grams of carbohydrates you should have a day by watching the videos “What are carbohydrate portions?” and “How much carbohydrate is in the foods I like to eat?”


Consequences of high blood glucose levels

Ongoing high blood glucose levels will result in furthering the risk of developing consequences associated with diabetes. These consequences affect people with type 1 and type 2 diabetes in the same way.


Some consequences of ongoing high blood glucose levels include:

  • Kidney disease
  • Heart disease
  • Eye disease
  • Problems with the feet, skin, and teeth and gums

Fruit juice vs whole fruit

When juicing fruit, all of the flesh is removed, leaving the liquid component being the juice. The flesh of fruit also contains fibre. Removing fibre increases the sugar content of juice, effectively concentrating the amount of sugar you are consuming.


A whole piece of fruit provides better nutrition and blood glucose management. Whole fruits are digested more slowly, so your blood glucose levels won’t rise as quickly compared to juice. The fibre content of fruit will also increase the feeling of fullness and contribute to healthy bowel function, as well as reduce the risk of developing other chronic diseases.


While eating a whole piece of fruit is better than drinking fruit juice, people with diabetes should still be mindful of how much fruit they consume in one day.






What should I drink instead of fruit juice?

The best alternative to drinking fruit juice is water. Drinking water has no effect on blood glucose levels, making it the best option for people who have diabetes. Another great benefit of water is it’s free from our taps!
