There are several potential cranberry juice side effects. These include: Diarrhea and Kidney stones, gastritis, and diabetes. These side effects can be dangerous so be aware before you start taking any new supplement. However, in many cases, these side effects are not serious enough to warrant immediate withdrawal.
Diarrhoea
Cranberry juice is rich in natural salicylates, which can help reduce the amount of Enterobacteriaceae. This type of bacteria is commonly found in people with digestive issues and is responsible for constipation. Cranberry juice also helps the body retain water in the colon, which makes the stool more compact.
Kidney stones
Although cranberry juice is good for the bladder and urinary functions, it can also cause kidney stones in some people. These stones are formed by a buildup of calcium in the kidneys. They are painful and can cause nausea and sharp pain in the abdomen.
Diabetes
A recent study examined the effects of cranberry extract on blood glucose levels in type 2 diabetic patients. It found that the juice improved fasting glucose levels and improved some biomarkers of oxidation and inflammation. However, the results were not statistically significant.
Gastritis
Cranberry extract powder has been shown to suppress the growth of the bacteria that causes peptic ulcer and gastritis. It also inhibits gastric cells from secreting interleukin-8 (IL-8). Several studies have shown that cranberry can also reduce the rate of stomach cancer in humans.
Plaque for the teeth
The antimicrobial plant polyphenols in cranberry juice can help prevent dental plaque. These compounds inhibit the formation of plaque-forming enzymes and stop bacteria from sticking to tooth surfaces. This effect is similar to the one seen with black tea.
Skin health
Cranberry juice contains an abundance of vitamin C, which helps the skin stay healthy. This vitamin is responsible for the production of collagen, which gives the skin its structure. It also helps prevent the aging process by protecting against UV light damage.
Cancer
Recent research has shown that cranberry juice may reduce the risk of developing cancer. It was found that cranberry juice contained a high amount of polyphenols, which reduced the viability and viability of cancer cells. This substance is likely composed of anthocyanins and proanthocyanidins, which are high molecular weight polyphenolic compounds.
