Potential benefits
Cranberries may be beneficial for health because they contain antioxidants, including vitamin C and flavonoids. These compounds help protect cells from oxidative stress.
Compounds found in cranberries may also help prevent certain bacteria from attaching to the lining of the urinary tract. For this reason, cranberries are often associated with urinary tract health and a potentially lower risk of recurrent urinary tract infections.
Cranberries may contribute to a diet that supports cardiovascular health. The plant compounds they contain are being studied for their potential effects on blood pressure, cholesterol levels, and inflammatory processes.
Cranberries can also be a useful part of a varied diet. They contain vitamin C and dietary fibre, while their relatively low calorie content makes them easy to combine with other fruits, berries, porridge, or fermented dairy products.
Possible side effects
Possible side effects of cranberries include gastrointestinal discomfort, interactions with anticoagulants, and rare allergic reactions.
Because of their acidity, consuming larger amounts of cranberries may cause gastrointestinal discomfort in some people, such as stomach upset, diarrhoea, or bloating.
People taking certain medications, especially anticoagulants such as warfarin, should be cautious. Cranberries may interact with some medications, so it is advisable to consult a doctor or pharmacist before significantly increasing the amount of cranberries in your diet.
Allergic reactions to cranberries are rare, but sensitive individuals may experience symptoms such as hives, swelling, or breathing difficulties.
As with other foods, moderation is important, and it is worth paying attention to how your body responds.

Frequently asked questions
Can cranberries help with urinary tract infections?
Cranberries may be beneficial for urinary tract health and, in some cases, may help reduce the risk of recurrent urinary tract infections.
The active compounds in cranberries, particularly proanthocyanidins, may help prevent certain bacteria from attaching to the lining of the urinary tract.
Some studies suggest a potential benefit in reducing the recurrence of urinary tract infections, but cranberries should not be considered a treatment for an existing infection.
If you experience symptoms of a urinary tract infection, consult a doctor for appropriate diagnosis and treatment.
Are cranberries safe for pregnant and breastfeeding women?
Cranberries can generally be consumed in moderate amounts during pregnancy and breastfeeding as part of a balanced diet.
They provide vitamin C, dietary fibre, and other plant compounds.
Larger amounts or concentrated cranberry supplements may cause gastrointestinal discomfort or interact with certain medications.
During pregnancy or breastfeeding, it is advisable to consult a doctor before taking cranberry supplements or significantly increasing the amount of cranberries in your diet.
