Cranberries: Health advantages, nutritional aspects, and potential hazards
Cranberries, a native North American fruit, have gained a reputation as a superfood due to their high nutrient and antioxidant content. One of the most widely studied aspects of cranberry consumption is its potential to prevent urinary tract infections (UTIs).
Research has linked cranberries to a lower risk of UTIs, improved immune function, and decreased blood pressure. A systematic review found that supplementing cranberries in the diet may help manage several risk factors for cardiovascular disease (CVD), such as systolic blood pressure, body mass index (BMI), and high-density lipoprotein (HDL) levels.
When it comes to UTIs, cranberry products have been shown to reduce the number of infections in specific groups. For instance, women with recurrent UTIs, children, and patients undergoing urinary tract procedures have experienced a notable decrease in UTIs, with a 26% decrease in women, 54% in children, and 53% in patients undergoing urinary procedures.
However, there is no significant reduction in UTIs among elderly individuals in long-term care facilities, adults with neuromuscular bladder dysfunction, or pregnant women. The effectiveness of cranberry products appears to be restricted to UTIs caused by *Escherichia coli*, likely due to proanthocyanidins in cranberries preventing bacterial adhesion to urinary tract cells.
Both cranberry juice and supplements (capsules or tablets) seem to be equally effective in preventing UTIs, although the exact dosage and form of consumption can vary. Pure cranberry juice is often more effective than commercial cranberry juice cocktails, which are typically sweetened and contain less actual cranberry juice.
The recommended intake of proanthocyanidins (PACs) for potential UTI prevention is about 36 mg, though many supplements contain less than this amount. Cranberry products are generally safe, with minimal adverse effects. However, they can cause stomach upset due to acidity and high sugar content in juice forms.
It's important to note that while cranberry products may offer some benefit in preventing UTIs in certain populations, they are not a substitute for antibiotics in treating active infections. More consistent dosing and high-quality studies are needed to fully understand their effectiveness.
When buying cranberries, they should be firm to the touch and unwrinkled. When selecting juice and cranberry products, a person should look for products with little to no sugar. Dried cranberries, like other dried fruit, are often made with added sugar. A person should check the sugar content if they are concerned about their sugar intake or make their own dried fruit at home without adding sugar.
Cranberries, whether in the form of juice, tablets, or capsules, are a natural food with potential health benefits beyond UTI prevention. They may help with oral health, possibly helping with cancer care. However, it's always advisable to discuss consumption with a doctor for certain situations such as pregnancy, UTIs, blood-thinning medications, nursing, stomach issues, and a history of kidney stones.
