It’s not surprising that prunes fell out of favour considering their close association with relieving constipation. Prunes (or shall we call them dried plums?) have been sold as a popular digestive remedy for decades mainly because of these three components: fibre, sorbitol (a sugar alcohol that can loosen the stool) and a natural laxative compound called diphenyl isatin.
protect against cardiovascular diseases and other chronic illnesses
Prunes and plums contain high levels of phytonutrients called phenols. They’re particularly high in two unique phytonutrients called neochlorogenic and chlorogenic acid. Numerous studies show that these phytonutrients help to prevent damage to cells particularly when it comes to the oxidation of lipid molecules in the body. Since all of our cell membranes, as well as our brain cells, are largely made up of lipids which contain fat, these are important phytonutrients to have in the diet. These compounds have also been found to inhibit the oxidation of LDL cholesterol in the body, making them an important factor in the prevention of chronic diseases.
They help prevent type 2 diabetes and obesity
Prunes and plums are high in soluble fibre that helps to keep blood sugar levels stable. Soluble fibre slows the rate that food leaves the stomach and, as a result, delays the absorption of sugar into the blood stream. Soluble fibre also increases the body’s sensitivity to insulin.
Prunes and plums help to lower cholesterol
The soluble fibre we just spoke of also helps to lower cholesterol by soaking up excess bile in the intestine and then excreting it. Bile is made from cholesterol in the liver in order to digest fat. When the body excretes bile along with the fibre from prunes and plums, the liver must use cholesterol in the body to make more bile thereby lowering the amount in circulation in the body. Soluble fibre may also inhibit the amount of cholesterol manufactured by the liver in the first place. A study found that prunes are more effective than psyllium at relieving constipation.
