Health Benefits of Cranberry
- Prevents Urinary Tract Infections – Urinary tract infection refers to the presence of microorganisms in the urine beyond the permissible limit. There is significant evidence that suggests that cranberry juice helps to prevent urinary tract infection. The proanthocyanidins found in cranberry juice prevent the bacteria from binding to the cells of the bladder walls. These compounds prevent the bacteria from multiplying further and flush them out of the body through urine. This juice makes the urine more acidic, thus creating an environment that is inhospitable for the infection-causing bacteria to thrive. Drinking cranberry juice regularly can prevent recurring tract infections in middle-aged and pregnant women.
- Anti-tumor Properties – The polyphenol compound present in cranberry has anti-tumor effects. Regular consumption of cranberry juice inhibits the development and spread of lung, breast, colon and prostate tumors. The presence of salicylic acid reduces swelling and prevents the formation of blood clots which can lead to a tumor. The anti-tumor efficacy offered by cranberry juice is attributed to the presence of polyphenolic compounds within the fruit.  A study led by Dr.  Polly Ferguson, Department of Physiology & Pharmacology, University of Western Ontario suggested that regular consumption of cranberry juice inhibits the development and spread of lung, breast, colon, prostate, and other cancers. Cranberry juice contains a high amount of salicylic acid which can help reduce swelling, prevent blood clots, and eliminate tumors. These compounds found in cranberries suppress the oxidation of low-density lipoprotein and encourage the formation of blood platelets (9).
- Combats Tooth Decay – Cranberry juice is also known to prevent tooth decay. Proanthocyanidin, found in cranberries, inhibits the growth of bacteria that cause plaque and prevents the decay of teeth due to development of cavities (10). Good dental hygiene along with a moderate consumption of cranberry juice disrupts the mechanism of pathogenesis and promotes good dental health. Unsweetened cranberry juice decreases the incidence of the bacteria that are found in the mouth and combats bad breath too. A healthy dose of this juice ensures clean teeth at all times.
- Improves Heart Health – Cranberry juice can help lower the risk of heart-related ailments and assist in sustaining cardiovascular health. The flavonoids present in cranberries have antioxidant properties and may decrease the threat of atherosclerosis.  Atherosclerosis is a disease in which the arteries are narrowed due to the build-up of fat, calcium, and cholesterol found in blood.  This obstructs the flow of oxygen-rich blood to various parts of the body and may lead to potentially fatal outcomes like heart attacks and strokes. These compounds have been shown to delay and suppress the oxidation of low-density lipoprotein (LDL cholesterol) and beneficially stimulate the blood platelets.
- Prevents Cancer – Incorporating cranberry juice into the daily diet can even prevent the occurrence of certain types of cancers . Cranberry contains proanthocyanidins, which inhibit the growth of various cancer cells. Studies have suggested that diets rich in flavonoids play a fundamental role in reducing the risk of cancer as well as cancer mortality.  Cranberry juice contains anti-carcinogenic components that interfere with the growth of cancer cells, particularly those associated with colon and prostate cancer. 
- Improves Digestion – Peptic ulcers are caused by a type of bacteria called Helicobacter pylori or H. pylori. This microorganism attacks the protective layer of the stomach and duodenum, which is a first part of the intestine. This may lead to further inflammation of the stomach lining. Foods rich in flavonoids, a category that includes anthocyanins, flavonols, and proanthocyanidins, like cranberries, apples, and garlic help reduce the risk of stomach disorders, including stomach ulcers, by inhibiting the growth of H. pylori bacteria. An investigative study by the Beijing Institute for Cancer Research performed on a group of patients having that type of stomach disorders showed a 50% advantage over patients who didn’t consume cranberry juice.

Cranberries have a multitude of therapeutic properties that protect the cells from damage caused by unstable molecules called free radicals that contribute to aging, thereby making the skin look younger. 
- Prevents Tooth Decay – According to new research studies, cranberry juice prevents tooth cavities. Proanthocyanidins, a chemical compound present in cranberries, inhibits harmful bacteria from clinging to teeth.  These components inhibit acid production and protect the teeth from periodontal diseases by preventing the growth of plaque. Good oral hygiene, along with the consumption of organic premium dried cranberries, disrupts the pathogenic mechanism of dental caries and generally makes for good dental health.  At the same time, one should watch out for the soaring sugar content and the acidity of some commercially available juices – natural cranberry juice is always better!
- Avoids Respiratory Infections – According to conducted studies, cranberry juice helps inhibit certain strains of the Haemophilus influenza, which is a common cause of ear and respiratory infections in children.
