Cranberry Juice Health Benefits


The health benefits of cranberry juice include relief from urinary tract infection, respiratory disorders, kidney stones, cancer, and heart disease. It is also beneficial in preventing stomach disorders and diabetes, as well as gum diseases caused by dental plaque. Phytonutrients, which are naturally derived plant compounds, are present in cranberries and have been found to prevent a wide range of health problems.

Cranberries are a versatile fruit and their benefits make them useful in food as well as in medicinal products. The Latin name for cranberry plant is Vaccinium macrocarpon and it is one of the native fruits of North America. Cranberries have a tremendous amount of antioxidant capacity as compared to other fruits and vegetables like broccoli, spinach, and apples. One cup of cranberries offers a total 8983 antioxidant capacity.

 

Nutritional Value of Cranberry Juice

Cranberry juice is rich in antioxidants, vitamin C and salicylic acid. By containing only 45 calories per cup, cranberry juice fits very well within the dietary guidelines. Cranberry juice also contains 87.13 g water per 100 g. It also provides energy, protein and carbohydrates. In terms of minerals, it contains calcium, magnesium, iron, phosphorus, sodium, potassium and zinc. It also contains vitamins like thiamin, riboflavin, niacin, vitamin B-6, E (alpha tocopherol) and vitamin K (phylloquinone). Cranberries are members of the Ericaceae family, and is native to North America.

 

Health Benefits of Cranberry Juice

Cranberry juice has long been used for curing various illnesses. Some of the health benefits of cranberries include the following.

Urinary tract Infections (UTI): Urinary tract infections refer to the existence of certain micro-organisms in the urine that exceed normal levels. These infections can develop in the bladder and cause cystitis, in the kidney to cause renal parenchyma, or in the prostate resulting in bacterial prostatitis. Studies have shown that the cranberry juice contains proanthocyanidins that possess anti-clinging properties, which prevent the bacteria from binding itself to the cells on the walls of the bladder. These compounds prevent these bacteria from multiplying and further and flush them out of the body through urination.
 
Research shows that drinking cranberry juice regularly can help prevent recurring UTIs in middle-aged women and pregnant women. Regular intake of cranberry juice has also been proven beneficial for patients undergoing other treatments in the hospitals as a guard against the urinary tract diseases. However, cranberry juice is not effective in treating UTIs once you have the infection, and is only a preventative measure.


Antitumor Effects: The anti-tumor efficacy offered by cranberry juice is attributed to the presence of polyphenolic compounds within the fruit. Studies have suggested that regular consumption of cranberry juice inhibits the development and spread of lung, breast, colon, prostate and other cancerous tumors. Cranberry juice contains a high amount of salicylic acid which can help reduce swelling, prevent blood clots, and eliminate tumors.
 
Cardiovascular 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 the blood. This obstructs the flow of oxygen-rich blood to the 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) and beneficially stimulate the blood platelets.

Prevents Tooth Decay: According to new research studies, cranberry juice prevents tooth cavities. Proanthocyanidine, a chemical compound present in cranberries, inhibits the harmful bacteria from clinging to the teeth. These components inhibit acid production and protect the teeth from periodontal disease by preventing the growth of plaque. Good oral hygiene, along with the consumption of 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 cranberry juices – natural juice is always better!

Avoid Respiratory Infections: According to conducted studies, cranberry juice helps to inhibit certain strains of the Haemophilus influenza, which is a common cause of ear and respiratory infections in children. The juice inhibits the bacteria’s hair-like structures, inhibiting them from adhering to the surface of the skin.

Prevents Cancer: 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 and cancer mortality. Cranberry juice contains anti-carcinogenic components that interfere with the growth of cancer cells, particularly those associated with colon and prostate cancer. According to studies, proanthocyanidins can stop micro-tumors from developing in the blood vessels. Regular consumption of cranberry juice prevents the rapid growth of tumors. Chemicals in cranberries also prevent the multiplication of breast cancer cells.

Strengthens Bones and Teeth: Although cranberry juice is a natural source of calcium, many juice companies add extra calcium to cranberry juice. Natural or otherwise, calcium reduces the risk of getting osteoporosis.

Cures Cold: Fresh cranberry juice is effective at fighting against infections. It cures sore throats and colds.

Good for Obesity: Cranberry juice is rich in organic acids, which have an emulsifying effect on the fat deposits in our body. So, it is good for people who want to shed those extra kilos.

Prevents Kidney Stones: The high amount of acid components in cranberry juice prevents kidney stone formation.

Peptic ulcers: 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 the first part of 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 helps reduce the risk of stomach disorders, including stomach ulcers, by inhibiting the growth of H. pylori bacteria. An investigative study performed on a group of patients having that type of stomach disorders showed a 50% advantage over patients that didn’t consume cranberry juice. Therefore, doctors commonly advise the regular intake of cranberry juice to suppress the infection.

Scurvy: Deficiency of vitamin-C in an individual can result in scurvy. Cranberries provide high levels of vitamin-C, which is also vital for the body to make collagen, the main component behind the healthy functioning of tissues.

Lung inflammation: The anti-inflammatory effects of cranberry juice have been proven to be effective against the inflammation caused in the lungs by the influenza virus. A substance called nondialyzable material or NDM present in the cranberries prevents the influenza virus from sticking to the cells and hence preventing a flu infection.

Anti-Aging Benefits: The USDA scientists at the human research center suggest that the wealth of phytonutrients and antioxidants present in cranberries play a vital role in providing protection against the problems that develop with age such as memory loss and lack of coordination. Cranberries have a multitude of therapeutic properties that protect the cells from the damage caused by unstable molecules called free radicals that contribute to aging, thereby making the skin look younger.

Foods: Cranberry fruit extract is used in making various sauces and cranberry juice cocktail. About one liter of juice can be extracted from 1500 grams of fresh cranberries. Cranberry juice cocktails are approximately 30% pure cranberry juice mixed with artificial sweetener or fructose. Dried cranberries can be enjoyed with breakfast cereals or can be added to muffins.

A Word of Caution
Cranberries and cranberry juice offer a variety of health benefits, barring the few exceptions listed below:

Warfarin (Coumadin)Warfarin is an anticoagulant drug that is used as a blood thinner, and it lowers the chances of blood clots occurring in the body. These blood clots can further result in serious conditions like cardiovascular disorders or clots in the legs, lungs, and other parts of the cardiovascular system. There are indications that people who take warfarin should be cautious regarding the intake of cranberry, as they are at a high risk of bleeding. Excess consumption of cranberry juice is not recommended for those people as it may affect the efficacy and safety of warfarin in the body. In such cases, it is always advisable to regularly get your blood tested in order to consume the correct dose of the medication.

Aspirin allergy: Cranberries contain substantial quantities of salicylic acid, which is also present in aspirin. People who need blood thinners and are prescribed aspirin should avoid consuming too much cranberry juice. Intake of cranberries should also be restricted if you are allergic to aspirin.

Kidney stones: Cranberry extracts contain a significant concentration of oxalate and calcium. This amplifies the chances of developing calcium-oxalate stones and uric acid stones in certain people. People who have kidney stones or have a history of kidney stones should consult a medical professional before consuming cranberry supplements or a large amount of cranberry juice. Studies have provided evidence that cranberry juice can raise the level of oxalate in the urine by up to 43%.
Cranberry extracts have been used to deodorize urine in some people who have complications in controlling urination, also known as urinary incontinence. The extracts can prevent the urinary catheters from blocking and speed up the curative process of the membrane around the stomach.

A Final Word on Cranberry Juice: Unsweetened cranberry juice tastes slightly sour, but for medicinal purposes, 2 ounces of cranberry juice diluted in 8 ounces of water is recommended. It is very good for your overall health. Finally, cranberry juice strengthens the immune system and helps to relieve stress. It works well for the skin conditions like acne and can be consumed dried, fresh or frozen.

Enjoy cranberries in any form you like, and also enjoy the wealth of health benefits you can get from this powerful little fruit!

Causes of Low Blood Pressure


 Blood pressure is a measurement of the pressure in your arteries during the active and resting phases of each heartbeat. Here's what the numbers mean:
  • Systolic pressure. The first (top) number in a blood pressure reading, this is the amount of pressure your heart generates when pumping blood through your arteries to the rest of your body.
  • Diastolic pressure. The second (bottom) number in a blood pressure reading, this refers to the amount of pressure in your arteries when your heart is at rest between beats.
Current guidelines identify normal blood pressure as lower than 120/80 mm Hg.
Although you can get an accurate blood pressure reading at any given time, blood pressure isn't always the same. It can vary considerably in a short amount of time — sometimes from one heartbeat to the next, depending on body position, breathing rhythm, stress level, physical condition, medications you take, what you eat and drink, and even time of day. Blood pressure is usually lowest at night and rises sharply on waking.

Blood pressure: How low can you go?

What's considered low blood pressure for you may be normal for someone else. Most doctors consider chronically low blood pressure too low only if it causes noticeable symptoms. Some experts define low blood pressure as readings lower than 90 mm Hg systolic or 60 mm Hg diastolic — you need to have only one number in the low range for your blood pressure to be considered lower than normal. In other words, if your systolic pressure is a perfect 115, but your diastolic pressure is 50, you're considered to have lower than normal pressure.

A sudden fall in blood pressure also can be dangerous. A change of just 20 mm Hg — a drop from 110 systolic to 90 mm Hg systolic, for example — can cause dizziness and fainting when the brain fails to receive an adequate supply of blood.
And big plunges, especially those caused by uncontrolled bleeding, severe infections or allergic reactions, can be life-threatening.

Athletes and people who exercise regularly tend to have lower blood pressure and a slower heart rate than do people who aren't as fit. So, in general, do nonsmokers and people who eat a healthy diet and maintain a normal weight.
But in some rare instances, low blood pressure can be a sign of serious, even life-threatening disorders.

Conditions that can cause low blood pressure

Some medical conditions can cause low blood pressure. These include:
  • Pregnancy. Because a woman's circulatory system expands rapidly during pregnancy, blood pressure is likely to drop. This is normal, and blood pressure usually returns to your pre-pregnancy level after you've given birth.
  • Heart problems. Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure.
    These conditions may cause low blood pressure because they prevent your body from being able to circulate enough blood.
     
  • Endocrine problems. Thyroid conditions — such as parathyroid disease — adrenal insufficiency (Addison's disease), low blood sugar (hypoglycemia) and, in some cases, diabetes can trigger low blood pressure.
  • Dehydration. When you become dehydrated, your body loses more water than it takes in. Even mild dehydration can cause weakness, dizziness and fatigue. Fever, vomiting, severe diarrhea, overuse of diuretics and strenuous exercise can all lead to dehydration.

    Far more serious is hypovolemic shock, a life-threatening complication of dehydration. It occurs when low blood volume causes a sudden drop in blood pressure and a reduction in the amount of oxygen reaching your tissues. If untreated, severe hypovolemic shock can cause death within a few minutes or hours.

  • Blood loss. Losing a lot of blood from a major injury or internal bleeding reduces the amount of blood in your body, leading to a severe drop in blood pressure.
  • Severe infection (septicemia). Septicemia can happen when an infection in the body enters the bloodstream. This condition can lead to a life-threatening drop in blood pressure called septic shock.

  • Severe allergic reaction (anaphylaxis). Anaphylaxis is a severe and potentially life-threatening allergic reaction. Common triggers of anaphylaxis include foods, certain medications, insect venoms and latex. Anaphylaxis can cause breathing problems, hives, itching, a swollen throat and a drop in blood pressure. 
  • Lack of nutrients in your diet. A lack of the vitamins B-12 and folate can cause a condition in which your body doesn't produce enough red blood cells (anemia), causing low blood pressure.

Medications that can cause low blood pressure

Some medications you may take can also cause low blood pressure, including:
  • Diuretics (water pills), such as furosemide (Lasix) and hydrochlorothiazide (Microzide, Oretic)
  • Alpha blockers, such as prazosin (Minipress) and labetalol
  • Beta blockers, such as atenolol (Tenormin), propranolol (Inderal, Innopran XL, others) and timolol
  • Drugs for Parkinson's disease, such as pramipexole (Mirapex) or those containing levodopa
  • Certain types of antidepressants (tricyclic antidepressants), including doxepin (Silenor), imipramine (Tofranil), protriptyline (Vivactil) and trimipramine (Surmontil)
  • Sildenafil (Viagra) or tadalafil (Cialis), particularly in combination with the heart medication nitroglycerin

Types of low blood pressure

Doctors often break down low blood pressure (hypotension) into different categories, depending on the causes and other factors. Some types of low blood pressure include:
  • Low blood pressure on standing up (orthostatic, or postural, hypotension). This is a sudden drop in blood pressure when you stand up from a sitting position or if you stand up after lying down.

    Ordinarily, gravity causes blood to pool in your legs whenever you stand. Your body compensates for this by increasing your heart rate and constricting blood vessels, thereby ensuring that enough blood returns to your brain.
    But in people with orthostatic hypotension, this compensating mechanism fails and blood pressure falls, leading to symptoms of dizziness, lightheadedness, blurred vision and even fainting.

    Orthostatic hypotension can occur for a variety of reasons, including dehydration, prolonged bed rest, pregnancy, diabetes, heart problems, burns, excessive heat, large varicose veins and certain neurological disorders.

    A number of medications also can cause orthostatic hypotension, particularly drugs used to treat high blood pressure — diuretics, beta blockers, calcium channel blockers and angiotensin-converting enzyme (ACE) inhibitors — as well as antidepressants and drugs used to treat Parkinson's disease and erectile dysfunction.

    Orthostatic hypotension is especially common in older adults, with as many as 20 percent of those older than age 65 experiencing orthostatic hypotension.
    But orthostatic hypotension can also affect young, otherwise healthy people who stand up suddenly after sitting with their legs crossed for long periods or after working for a time in a squatting position.

  • Low blood pressure after eating (postprandial hypotension). Postprandial hypotension is a sudden drop in blood pressure after eating. It affects mostly older adults.
    Just as gravity pulls blood to your feet when you stand, a large amount of blood flows to your digestive tract after you eat.

    Ordinarily, your body counteracts this by increasing your heart rate and constricting certain blood vessels to help maintain normal blood pressure. But in some people these mechanisms fail, leading to dizziness, faintness and falls.
    Postprandial hypotension is more likely to affect people with high blood pressure or autonomic nervous system disorders such as Parkinson's disease.
    Lowering the dose of blood pressure drugs and eating small, low-carbohydrate meals may help reduce symptoms.

  • Low blood pressure from faulty brain signals (neurally mediated hypotension). This disorder causes blood pressure to drop after standing for long periods, leading to signs and symptoms such as dizziness, nausea and fainting.

    Neurally mediated hypotension mostly affects young people, and it seems to occur because of a miscommunication between the heart and the brain.

    When you stand for extended periods, your blood pressure falls as blood pools in your legs. Normally, your body then makes adjustments to normalize your blood pressure.
    But in people with neurally mediated hypotension, nerves in the heart's left ventricle actually signal the brain that blood pressure is too high, rather than too low.

    As a result, the brain lessens the heart rate, decreasing blood pressure even further. This causes more blood to pool in the legs and less blood to reach the brain, leading to lightheadedness and fainting.

  • Low blood pressure due to nervous system damage (multiple system atrophy with orthostatic hypotension). Also called Shy-Drager syndrome, this rare disorder causes progressive damage to the autonomic nervous system, which controls involuntary functions such as blood pressure, heart rate, breathing and digestion.

    Although this condition can be associated with muscle tremors, slowed movement, problems with coordination and speech, and incontinence, its main characteristic is severe orthostatic hypotension in combination with very high blood pressure when lying down.
