Oxalate content

The oxalate content of Kiwifruit is 20 mg per 100 grams. Kiwifruit is considered low in oxalates. There is no information about the oxalate content of prunes.

Glycemic Index

Prunes have a low glycemic index. The glycemic index of prunes is 29. Kiwifruit has a glycemic index of 58. Kiwi is a medium-GI food.

Acidity

Kiwifruit and prunes are alkaline-forming foods; prunes are considerably more alkaline, with a PRAL value of -13.4 compared to kiwifruit's -5.6. 

Antioxidant activities

Kiwifruit and prunes offer impressive health benefits due to their rich antioxidant and anti-inflammatory properties. Kiwifruit is exceptionally high in vitamins C and E, carotenoids like lutein, zeaxanthin, and beta-carotene, and polyphenol compounds like chlorogenic acid and caffeic acid (1,2,3,4). These nutrients contribute to heart health, reduce the risk of cancer and overall mortality, and support immune function. Kiwis also enhance digestive health due to their high fiber content. Conversely, prunes are rich in polyphenols, which have potent antioxidant and anti-inflammatory effects, reducing markers of inflammation and oxidation (5). 

Cardiovascular Health

Kiwifruit consumption is linked to reductions in blood pressure, cholesterol levels, and platelet aggregation, lowering the risk of atherosclerosis and cardiovascular disease, particularly in smokers(6,7,8,9). Prunes, high in potassium and fiber, help to manage blood pressure and reduce blood cholesterol levels, lowering the risk of cardiovascular disease, particularly in postmenopausal women (10,11,12). While kiwifruit excels in improving lipid profiles and lowering blood pressure, prunes are notable for their potassium content and positive effects on blood lipid control. 

  Digestive Health

Studies indicate that kiwis can improve stool consistency and alleviate chronic constipation. Additionally, Kiwis support gut health by promoting beneficial gut bacteria (13,14). Prunes, high in fiber and low in glycemic index, help manage weight by prolonging satiety and stabilizing blood sugar levels. They also positively influence gut microbiota, increasing beneficial bifidobacteria and potentially lowering the risk of colon cancer (15,16).
