Top 5 health benefits of prunes

1. May support bone health

Including prunes in your diet may be beneficial for maintaining healthy, strong bones. In fact, animal studies suggest prunes are effective at not only preventing bone loss but helping to reverse it too. This makes them especially relevant for mid-life adults who may be at risk of osteoporosis.

2. May promote a healthy heart

A plentiful source of fibre, prunes are especially rich in a soluble fibre called pectin, which may help balance cholesterol levels. However, it’s not just the fibre which is beneficial the protective antioxidant properties of prunes appears to also help lower blood pressure as does the vitamin and mineral contribution, particularly the high levels of potassium.

3. May reduce the risk of type 2 diabetes

Eating fruit in its whole form, such as prunes, is associated with a reduced risk of type 2 diabetes. There are a number of explanations for this including their high fibre content, their rich phytochemical levels and micronutrient contribution. Furthermore, despite their sweet taste prunes don’t actually cause the typical rise in blood sugar and insulin seen after eating sweet foods.

4. May slow the ageing process

Prunes may help slow the ageing process, they do this thanks to their exceptionally high antioxidant levels, which is thought to be as much as twice that of other fruit and vegetables.

Animal studies have shown that feeding diets rich in these antioxidants appears to have a beneficial effect on alleviating levels of anxiety which in turn may reduce oxidative stress in the brain and delay its adverse effects on cognitive function.

5. Supports digestive health

As well as being rich in fibre prunes also supply sorbitol and phytonutrients which all work to support bowel function. This means eating prunes can increase stool volume and frequency making them a natural laxative which helps to promote healthy bowel movements. They also have prebiotic properties which means they supply the fuel to support the beneficial bacteria which reside in our intestines.

If you are experiencing constipation it’s worth visiting your GP to ensure that there are no underlying reasons. However, there is some evidence that prunes may help relieve constipation, and may in fact be better than other natural foods such as psyllium husks.

A recent study using 80g of prunes with 300ml of water a day for four weeks saw improvements in bowel function. However, it’s worth remembering we are all different and prunes may not work for everyone.

Are prunes safe for everyone?

Some people are allergic to prunes. They fall into the ‘birch pollen’ category of allergens, along with apples and plums, and they may cause itching and swelling of the mouth or throat in those affected.

Allergy symptoms normally develop within minutes, and you should see your GP if you experience an adverse reaction. However, if this develops into a severe reaction, known as anaphylaxis, it is a medical emergency and you should call for an ambulance immediately.

Read more about allergies on the NHS website.

If you are not used to high levels of fibre in your diet but you wish to try prunes to ease constipation, it would be advisable to start with 1-2 prunes each day, with adequate amounts of water, and build up slowly to find your tolerance. Prune juice is unlikely to produce the same effect as the fibre is removed during the juicing process.
