A guide to prune juice

If you have decided to look into prune juice,  it may be that you are looking for ways in which you can help bowel movement or constipation. However, there is much more to prunes than you might think.

Prunes, or dried plums, can be a good addition to your diet and can be beneficial for constipation due to their high levels of fibre.¹

In the following article we’ll go through the motions, so you can learn what introducing prune juice into your diet can do.

Is prune juice good for you?

Prune juice is filtered so it doesn’t contain as much fibre as dried prunes, however both are good for your overall health.

While there is limited scientific proof that prunes can help with digestion relief, it’s commonly thought that prunes and prune juice can keep you regular.  

However, there are a number of additional benefits that prune juice can have on your health.

A 2013 study looked at the health benefits of prunes and prune juice.² Researchers noted that the fruit contains considerable amounts of a sugar alcohol called sorbitol. It was found that prune juice contains 6.1g of sorbitol per 100g of juice, which could be an explanation for its laxative qualities.

Sugar alcohols are a category of sweet carbohydrates and are partially resistant to digestion. Sorbitol in particular passes through your body undigested. It then draws water into the gut, which bulks up the stool and increases bowel movement.

Sorbitol is an effective laxative, which is safe to use, even for older adults.³ Despite the ‘alcohol’ part of the name, alcohol sugars do not contain ethanol, the compound that makes you drunk.

Summary

• Prune juice is filtered and does not contain as much fibre as dried prunes
• Prunes and prune juice contains 6.1g of the alcohol sugar, sorbitol per 100g of juice
• Sorbitol draws water into the gut, which increases bowel movement
• Despite the alcohol name, alcohol sugars don’t contain ethanol and are safe to use

Five health benefits of prunes

We know that prunes can aid digestion. But there are more prune and prune juice benefits when adding them to your diet.

Here we will provide five ways in which the addition of prune juice in your diet can help:

1. Helps digestion

It’s definitely worth repeating that prunes and prune juice are high in fibre, which helps constipation.

Dried plums contain more than double the amount of sorbitol than juice, at 14.7g per 100g of dried fruit – compared to the 6.1g per 100g serving of prune juice. However, both are rich in fibre and have been known to soften stool consistency.⁴

While prunes may not be scientifically proven to fix constipation, it is noted that prunes and their juice are a healthier, safer and tastier first line therapy for mild to moderate constipation.⁵

Prune juice weight loss claims

Research from the University of Liverpool on the effects of prunes for weight loss suggest that it can actually help as part of a healthy diet.⁵

They study tested the effects of prunes on weight and appetite on 100 overweight and low fibre consumers over a twelve-week period.

Participants were divided into two groups – those who ate prunes every day (140g a day for women and 171g a day for men) and those who were given advice on healthy snacks over the period of active weight loss.

Research found that members of the group which ate prunes as part of a healthy life-style diet lost 2kg in weight and shed 2.5cm off their waists.  However, the people in the group which was given advice on healthy snacks lost only 1.5kg in weight and 1.7cm from their waists.

Summary

• Prunes are high in fibre, which helps digestion
• Juicing prunes will lose some of the fibre
• Prunes and prune juice can help mild constipation
• Prunes can help weight loss in a controlled diet

2. Helps control the bladder

Adding fibre to your diet can help with discomfort of having an overactive bladder.

Obviously, there are many things that can cause an overactive bladder, but one known reason is constipation. It stands to reason that the addition of prunes or prune juice to your diet could help with eliminating bladder irritants.⁶

• Constipation can have an effect on your bladder
• Prune juice could help with both of the above

Prunes and prune juice are a good source of potassium.

Potassium is an electrolyte, which helps the body achieve various bodily functions.

Potassium is needed for⁷:

• maintenance of normal blood pressure
• healthy muscle function
• supporting the nervous system

it works by conducting nerve signals throughout the body to generate muscle contractions, including those in the heart and gut. As we don’t naturally produce potassium, prune juice is a good way of adding more potassium to your diet.

The NHS suggests that adults (aged 19-64) should have 3,500mg of potassium a day, which you should get from a healthy, balanced diet.⁸

Summary

• Prunes are high in potassium which can help the body perform many important functions
• The body doesn’t naturally produce potassium, so prunes are a good source
• NHS suggest adults aged between 19-64 should have 3,500mg of potassium per day

4. High in vitamins

Vitamins provide essential nutrients for the body, and prunes contain a number of key vitamins.

In 64g of prunes you will find:

Vitamin A does a lot for your skin. From helping the healing process and supporting the immune system and promoting natural moisture.⁹ Vitamin K aids blood clotting and wound healing. It keeps your bones healthy too.

Riboflavin and niacin are part of B vitamins that help many things to help the body function, including; the brain and nervous system, cell reproduction, normal immune function and releasing energy from food.

Summary

• Prunes contain a number of key vitamins that your body requires

5. Good source of iron

When the body doesn’t get enough iron it can lead to deficiency. By improving your iron intake you will improve the quality of your red blood cells.¹¹

Prune juice is a great source of iron and can help the body get the right amount.

Symptoms of iron deficiency can include:
