How is Cranberry Juice Made?

While it may not matter to some, the process behind how the foods we put into our bodies are made are of high interest to others, and for that reason, we thought it was important to explain how cranberry juice is made. 

When searching for the way in which cranberry juice is made online, descriptions of the drink’s manufacturing process may vary depending on the distribution company and recipe involved. 

However, the general method behind making cranberry juice begins with a wet-harvesting process, in which the berries are harvested with a wet reel machine that separates the berry from the vine. 

The berries then go through a sequence of fruit crushing, mash maceration, mash heating, juice pressing, and pasturesiation, which in turn produces cranberry concentrate that is then separated from its pulp. 

In order to become sterilized the cranberry juice is placed through a thermal processing in order to eliminate any pathogenic or spoilage microorganisms and spores. During this process the juice is packed into aseptic, hermetically sealed containers which aid the sterilization. 

Please note that making regular concentrated cranberry juice ends here, however, for other variations additives are later included in the recipe.  

Naturally occurring cranberry juice concentrate is incredibly tart and sharp, it usually needs to be sweetened with sugar or artificial sweeteners so it’s more palatable to drink. Please note that not all recipes contain sugar and natural cranberry juice is always available as a sugar-free alternative, any additives will be carefully labelled on the product. 

In order to prepare cranberry juice cocktail products, different kinds of fruit juice and water will be added before the sterilisation process. However, once again this difference will be labelled on the product’s label for you to analyse prior to purchase.

Although it isn’t as popular as other juice such as orange or apple juice, cranberry juice has many benefits. But first, take a look at this cranberry juice definition to see what exactly is in it!

Cranberry Juice Nutrition

The easiest way to find an answer to the question ‘is cranberry juice good for you?’,  is to look at the drink's nutritional properties. By doing this we can gain a better understanding of how pure cranberry juice benefits the human body.

Before we begin to look at specifics, we must remember that in order to answer ‘is cranberry juice good for you?’, we must first take into consideration different makes and brands. Natural cranberry juice benefits the body in a different way to artificially processed variations, therefore some brands may be better than the others. 

For the sake of analysing its nutritional profile, we will be using 240ML of Ocean Spray cranberry juice for reference: 

Total Fat - 0g

Calories - 100

Sodium - 10mg

Potassium - 50mg

Total Carbohydrates - 27g

Sugars - 25g

Salt - 0.02g

Vitamin C - 24mg 

When discussing the different variations of the drink, we feel it is important to mention cranberry juice cocktails. These drinks aren’t pure cranberry juice, and are instead mixed with different other fruit combinations, meaning you won’t get all the pure cranberry juice benefits. 

Cranberry juice cocktails are also often higher in sugar than natural cranberry juice, and don’t hold the same benefits of real cranberry juice, so try and avoid them when you’re shopping. 

One of the benefits of cranberry juice is that it contains vitamins A, B9, calcium, and very small quantities of iron, magnesium, and vitamin B3. Meaning that in just one glass your body will be provided with multiple vita nutrients and minerals. 

Therefore, the answer to the question ‘is cranberry juice good for you?’ is rather straightforward; natural cranberry juice holds many beneficial health properties whereas other variations are best left as occasional snacks or treats. 

Is Cranberry Juice Acidic?

Some consumers may not be too phased by the question ‘is cranberry juice good for you?’, instead their interests may lie in more commercialised interests, such as flavour and taste.

As an off-shoot to the question posed above, many often ask ‘is cranberry juice acidic?’, in order to gain a better understanding of how the beverage tastes. 

In short, yes, cranberry juice is acidic. Cranberry juice typically has a pH level of 2.5; everything below 7 on the pH scale is classified as being acidic, where anything above 7 is alkaline. The word acidic may be setting alarm bells off for some readers, however, please be aware that this doesn’t mean that these drinks are bad for you. 

Often the only negative connotations surrounding the question ‘is cranberry juice acidic’, comes from the damage acidic drinks can pose on your teeth (but more on that later!)

Benefits of Cranberry Juice

So, what is cranberry juice good for? This section is dedicated to breaking down the 11 beneficial properties of the drink and how it can be used to benefit your overall life and health. 

#1 - High in Vitamin C

When debating what are the benefits of cranberry juice, the first entry on our list is dedicated to it’s vitamin C content. 

Through it’s high vitamin C count, cranberry juice benefits a whole host of your bodily functions.

Not only does it keep your cells healthy and help with wound healing, but it also helps to maintain your bones and cartilage. 

Vitamin C is a powerful antioxidant that can also help to prevent many serious illnesses by combating particles called free radicals.

It's important to get plenty of vitamin C every day, as it does not get stored in our body, meaning we need to replenish it daily. Drinking cranberry juice benefits your body as it will contribute towards this intake.

However, you should not rely on the health benefits of cranberry juice as your sole source of vitamin C. Instead, be sure to incorporate foods such as fresh oranges into your diet, in order to receive the full health benefits.

#2 - Can Help With Your Skin

As the largest organ in your body it’s important to discuss the benefits of cranberry juice for skin. With just a simple glass a day you could see huge improvements in the quality of your skin.

Whatsmore, the benefits of cranberry juice for skin also extend to vitamin C’s relationship to collagen production in the body, which is known to strengthen your bones and provide your skin with structure. In essence, this means that your skin will be able to fight wrinkles and signs of aging. 

The best way to keep your skin healthy is to feed it from the inside with antioxidants and vitamins, which cranberry juice can help with. As an added bonus, cranberry juice benefits your skin through its water content, which will keep your skin hydrated in a delicious way. 

The benefits of cranberry juice for skin don’t end there, either! Getting enough vitamin C can help to prevent and heal dry skin, so if you struggle with dry patches, try working cranberry juice into your diet to boost your vitamin C intake.

#3 - Contains Polyphenols 

Cranberry juice benefits your long-term health in other ways too, in particular with its polyphenols contents. Polyphenols are plant-based compounds that have many health benefits, and cranberry juice contains plenty of them. There are many different types of polyphenols, but for the purpose of this particular article, cranberry juice contains anthocyanins in particular.

Anthocyanins are found in red and purple foods such as blackberries, blueberries, and red cabbage, and one of the benefits of real cranberry juice is that it is packed full of them. 

In the past anthocyanins have been linked to increased longevity and cancer prevention, as well as dementia prevention.

If you want to boost your consumption of polyphenols, cranberry juice is an amazing way to get more into your diet. A high polyphenol diet is associated with benefits such as longevity and higher immunity, so one of the major benefits of drinking cranberry juice is increasing your polyphenol levels. 

Another beverage that is high in polyphenols is green tea, and a detailed analysis of the benefits and side effects of this drink can be found on our blog

#4 - High In Antioxidants 

Another example of natural cranberry juice benefits is that it is high in antioxidants, are also known to fight off free radicals.

Further examples of beneficial foods can be found in OriGym’s dedicated list of the 25 best antioxidant-rich foods

Antioxidants help to combat the oxidative damage that occurs naturally in your body, said damage plays a role in serious illnesses such as Alzheimer’s disease and cataracts. 

Drinking cranberry juice benefits your health as it can boost your levels of antioxidants which helps to prevent these illnesses from occurring in the first place. 

The antioxidants in cranberry juice come from the high levels of vitamin C that it contains, as well as the polyphenols and phytochemicals. 

Therefore, we can state that the benefits of real cranberry juice is that it can help to prevent serious illnesses, ensuring that our body operates at optimum functioning. 

#5 - Helps to Prevent Serious Health Issues

We can view this next example of the benefits of cranberry juice as an off-shoot of the point made above, as the drink can help to prevent health issues and diseases such as cancer, diabetes, and heart disease. 

This is due to the antioxidants in cranberry juice, including polyphenols and vitamin C, which combat harmful free radicals in your body. 

This scientific study found that consuming a high polyphenol cranberry juice every day boosted antioxidant levels, reduced the risk for cardiovascular disease, and increased HDL cholesterol (otherwise known as ‘good’ cholesterol’).

Nuts have also been known to provide good cholesterol whilst improving the health of the consumer. For more information on this topic click here to read our list of the 11 healthiest nuts.

Increasing your polyphenol intake is also associated with lowering your risk for diabetes, as they can help to control your blood sugar levels. Fresh and no added sugar cranberry juice is great for this, as it contains high levels of polyphenols and low sugars. 

Therefore, when questioning is cranberry juice good for your long-term health, you can rest with the peace of mind knowing that your body will be better equipped for combating serious illnesses. 

#6 - Supports Heart Health

Thanks to the number of antioxidants and polyphenols, cranberry juice benefits your heart health and can decrease the risk for heart-related illnesses.

One study found that cranberry juice boosted ‘plasma antioxidant capacity in women with metabolic syndrome’ (an increased risk of heart disease). We can therefore say that an example of the benefits of cranberry juice for women is they’ll be less likely to have heart related illnesses post consumption.

However, just because this study centered around women’s response does not negate the fact that cranberry juice can be beneficial to men too. With both sexes this is achieved through boosting antioxidants throughout the body, which in turn combat the harmful free radicals. 

Therefore, we can conclude that cranberry juice benefits female and male consumers alike, by helping to protect your heart against serious cardiovascular diseases. So, if you’re looking to turn to the drink for its health benefits, you’ll be pleased to note it will provide you with a strong and healthy heart. 

For a strong and healthy heart you should pair a balanced diet with plenty of cardio exercise. Our article on cardio and aerobic exercise will detail how you can improve your cardiovascular health, through simple exercises such as running.

#7 - Can Support Post-Menopausal Health

One of the benefits of cranberry juice for women and people who menstruate is that it can help with your health during and after menopause. This is due to the fact that heart problems increase post-menopause, and cranberry juice can help to reduce cholesterol, keeping your heart healthier for longer. 

We have previously discussed how cranberry juice benefits a female's heart health, but did you know that it can also benefit the respiratory system too. This is highlighted through a study examining the benefits of berry flavonoids in menopausal women, which showed that there was some evidence to suggest cranberry juice could help in the prevention of esophageal cancer. 

Sunflower oil benefits menopausal health too, and if you find you’d to learn about natural remedies we’d strongly recommend checking our article. 

If you’re further questioning ‘is cranberry juice good for you post menopause’ then you’ll be happy to know that there are so many other benefits. For example, when experiencing this biological change many women report that dryness in their skin, which as we learned earlier in the article can be prevented by cranberry juice. 

#8 - Can Protect Your Teeth

‘What is cranberry juice good for in terms of oral health?’, many detractors of the drink often call into question how damaging it can be to your teeth. However, it may surprise you to learn that cranberry juice benefits your mouth by providing your teeth with a protective layer of film.

Whatsmore, unsweetened cranberry juice benefits gum health, as proven by this study from the Department of Microbiology at Tokyo Dental College. Which highlighted that the components in cranberry juice could stop bacteria gathering on the teeth and slow the development of plaque.

However, as discussed within the section ‘is cranberry juice acidic’, you must remember to maintain some form of oral care. This is due to the drinks pH level, which can lead to enamel softness. 

This is very similar to the benefits of apple cider vinegar, which can also be good for your overall health but damaging to your teeth due to its pH level. For further information on how this product can benefit your health give our article a read over!

OriGym recommends brushing your teeth one hour after consumption, as by doing so you'll be able to learn first hand is cranberry juice good for your teeth, without causing any unwanted damage. 

Whilst this list is dedicated to the benefits of cranberry juice, we would advise you to have some form of self-control and limit your intake, ideally drinking one proportion, or 150ml per day. 

#9 - Can Improve Your Digestive Health

Another example of unsweetened cranberry juice benefits is that it can help with your digestive system. This is due to the fact that the beverage can stop the growth of some bacteria, including one called H. pylori, which is known to cause stomach ulcers.

When debating what are the health benefits of cranberry juice, we can say that your digestive system is incredibly important, and if something goes wrong, it can have a huge knock-on effect which can lead to other serious health issues. 

Therefore, it’s vital to eat well in order to keep your digestive system healthy and working efficiently and one way to do that is by incorporating a cranberry juice diet into your system. 

This scientific study found that drinking cranberry juice significantly prevented the growth of H. pylori in the stomach, a bacteria known to cause stomach ulcers. These sores can develop in the lining of the stomach, and symptoms include indigestion, heartburn, and nausea, and reducing the bacteria that causes them is a major benefit of cranberry juice.

For further information related to food's relationship with the digestive system, we can recommend reading OriGym’s article on the 37 best foods for energy

Whilst this section of the article is dedicated to answering ‘what is cranberry juice good for’, we’d advise all consumers to be wary of drinking too much cranberry juice. Although it has benefits, drinking too much can cause an upset stomach, so make sure you’re sticking to around 150ml per day.

#10 - Low in Calories

It may surprise you to know but cranberry juice benefits weight loss, so if you’re looking for a sweet drink that you can consume without the worry of added sugar and calories get ready to pour yourself a glass. 

Compared to other fruit juices, one of the benefits of cranberry juice is that it can aid with weight loss thanks to the low number of calories that it contains. One serving typically contains only 23 calories, compared to the 70 found in orange juice. 

You can even get cranberry juice which is lower in calories if you choose a juice with no added sugar – for example, the Tesco cranberry juice with no added sugar has only 4 calories per serving! 

In the present day, there are many other diet drinks and teas that claim to be a miracle weight-loss supplement, however, they are often unnatural and bad for your digestive system. On the other hand, cranberry juice benefits weight loss and is naturally occurring, made with real fruits with no added preservatives. 

This makes cranberry juice an ideal substitute for other sugar fruit juices and fizzy drinks if you’re trying to lose weight but still want a sweet fix, even better yet this drink happens to be packed with amazing benefits.

Whilst pure cranberry juice benefits weight loss compared to other fruit juices, still always be mindful of the amount of sugar it contains. It can be easy to drink a lot more than you intend to, so try and limit yourself to one small glass of cranberry juice per day! 

Do you have a sweet tooth? Do you want another low calorie snack? Well if the answer to both those questions is yes, read our article on the 18 best healthy ice creams immediately, we promise you won’t regret it. 

#11 – Is Anti-Inflammatory 

If you are questioning ‘what are the health benefits of cranberry juice?’, one important factor you should be aware of is the drinks' anti-inflammatory properties. 

Inflammation occurs when your body is protecting you from bacteria or viruses, with your white blood cells racing to combat them before they can make you ill. This process can have symptoms such as redness around an era, fatigue, and a fever. 

Whilst the white blood cell process is amazing for fighting off infections, chronic inflammation can be harmful, and even lead to other illnesses. Unsweetened cranberry juice benefits the body by combating these separate illnesses, and reducing the risk of occurrence in the first place.

Cranberry juice is fantastic for inflammation thanks to the amounts of antioxidants and polyphenols that it contains. Drinking low-calorie cranberry juice could increase antioxidant capacity, which is great for reducing inflammation and fighting off free radicals.

This provides another answer to ‘what is cranberry juice good for?’, as we can see first hand the positive effects this fruit drink can have on your body’s health. 

By combating inflammation, one of the benefits of real cranberry juice is that it can help with severe illnesses which cause inflammation such as Crohn’s disease and colitis. If you want to fight inflammation through your diet, try combining cranberry juice with other foods with anti-inflammatory properties, such as fatty fish and broccoli.

Potential Cranberry Juice Side Effects

This article has largely been dedicated to answering the question ‘what is cranberry juice good for?’, however, in order to gain a better understanding of the drink as a whole, it is also necessary to be aware of the side effects it could have on your body. 

Whilst there are a few cranberry juice side effects to be wary of, please keep in mind that the benefits of the drink far outweigh the negatives. 

#1 - Cranberry Juice is Acidic 

As previously discussed within the section ‘is cranberry juice acidic?’, this particular fruit drink has a very low pH level of around 2.5, making it quite acidic. Acidic drinks can carry their own side effects, one of which includes wearing the enamel on your teeth down and increasing your risk of cavities.

As an example of cranberry juice side effects, we would advise drinkers with sensitive teeth to give this drink a miss, added consumption could lead to increased sensitivity and pain.

As well as wearing down the enamel,  cranberry juice side effects also include increasing the risk of cavities, and may also start a yellowing process on your teeth. 

Although it can help to protect your teeth, it is important to limit the amount that you drink due to the high acidity of cranberry juice. Along with this, remember to wait before you brush your teeth after having cranberry juice, as the enamel will be softer and can be damaged by brushing.

However, you can still enjoy all the benefits of cranberry juice; a great way to avoid the negatives that acidic drinks can have on your teeth is to drink them through a straw, as it limits contact with your tooth enamel. If you wish to avoid these cranberry juice side effects make sure to limit your intake of sugary and acidic drinks to help protect your teeth as much as possible.

#2 - Can Cause Stomach Issues

If you want to experience the cranberry juice benefits, men and women alike must avoid excess sugar.  While this drink can improve your digestive health, you can in fact have too much of a good thing! 

Not only can cranberry juice side effects extend to your teeth, but it can also cause you stomach issues, including an upset stomach and diarrhoea. 

Thankfully, this side effect is easy to prevent through simple portion control. The recommended daily amount of cranberry juice is 150ml, so if you have a history of stomach issues or this is something that you’re concerned about, stick to that limit, and consult your doctor if you’re worried.

However, if you experience any of these cranberry juice side effects, such as stomach pain or diarrhoea, don’t panic as they are easily treatable. Mint is an excellent treatment for both, as it helps to settle the stomach and prevent diarrhoea. 

Try drinking some mint tea, or having a few mint sweets or mint flavoured chewing gum, and remember to limit your cranberry juice intake next time! 

#3 - May Interfere With Certain Medications 

Another example of cranberry juice side effects is that it may interfere with some medicines, mainly blood thinners such as aspirin or warfarin, which is a medication used to slow blood clotting. 

Cranberry juice can cause warfarin to last longer in the body and increase your chances of bleeding and bruising. 

This is a very rare example of cranberry juice side effects, however, the reaction between warfarin and cranberry juice is still medically categorised as moderate rather than extreme. Other medications that cranberry juice and other cranberry related products are known to react with are two other anticoagulants, anisindione and dicumarol. 

If you’re worried about these cranberry juice side effects on your medication, talk to your doctor about what you’re taking and if it’s safe to drink it. Some medications may even have a label on it’s packaging, advising you to avoid certain foods.

#4 - Could Trigger an Aspirin Allergy 

Although it may sound odd, another one of cranberry juice's side effects is that it can be harmful if you have an aspirin allergy. This is due to the high amounts of salicylic acid in cranberries, which is very similar to aspirin – but don’t worry, this can only happen when you drink cranberry juice in very large quantities. 

Symptoms of an aspirin allergy can include itchy rashes, hives, and a blocked or runny nose. If you notice any of these symptoms after drinking cranberry juice, contact your doctor immediately and get some tests done – if you are allergic, you may not be able to take certain types of other medications, such as ibuprofen. 

Symptoms of cranberry juice affecting your medication can include dizziness, nausea, bruising, and vomiting, with more serious symptoms including blood appearing in your urine or stools. If you have any of these symptoms, contact your doctor immediately. 

If you have an aspirin allergy but want to get all the benefits of cranberry juice, talk to your doctor, as you may be able to drink smaller quantities. 

#5 - May Increase The Risk of Developing Kidney Stones

When discussing ‘what are the health benefits of cranberry juice?’, we must also share some health warnings, note that this is the most severe example of cranberry juice side effects to appear on our list. 

It is thought that cranberry juice, despite all the benefits, can contribute to kidney stones due to the high amounts of oxalate it contains. Oxalates, or oxalic acid, is a naturally occurring compound found in plants, but consuming too much can increase your risk for kidney stones.

Kidney stones are small stones caused by waste filtering through the kidneys and can range from so tiny you’ll never notice them to incredibly painful and large. To help with prevention, make sure you’re staying hydrated and limiting your salt intake.

If you’re at risk of kidney stones, you may be recommended a low-oxalate diet by your doctor, advising you to avoid foods such as spinach and soy products. If this is something that you’re worried about, be sure to consult with your doctor as to whether a low oxalate diet is for you. 

However, you can still enjoy the benefits of cranberry juice if you’re limiting oxalates! They are not present in dangerous amounts, and only become a risk if you’re consuming other foods with oxalates in. 

How to Choose The Best Cranberry Juice

In order to get all the benefits of real cranberry juice, ensure that you opt for a product that is low in both sugar and sweeteners. Natural cranberry juice offers many more benefits than one that is highly sweetened with sugar.

If you want the benefits of pure cranberry juice, make sure you avoid drinks mixed with other fruits such as blackcurrants. These are usually called cranberry juice cocktails and will usually be higher in sugar and calories than pure cranberry juice.

Additionally, it will also be more expensive than other cranberry juices, so you may have to choose a juice that fits around your budget the best.


Can Cranberry Juice Help With UTIs?

You might notice that this wasn’t listed in the benefits of cranberry juice, even though there is a strong belief that cranberry juice can combat nasty UTIs (urinary tract infections).  Many online articles often cite this point as an example of cranberry juice benefits for females who are statistically more likely to experience UTIs. 

However, there is no solid link between drinking cranberry juice and the prevention or treatment of UTIs, meaning that it’s hard to scientifically classify it as an example of the way in which cranberry juice benefits females. 

Scientific studies have given conflicting results and more research is needed to see if one of the natural cranberry juice benefits is the prevention of UTIs. If you do have a UTI, or think you do, it’s important that you go to a doctor for proper treatment – don’t think that cranberry juice will instantly cure you!

When is the Best Time to Drink Cranberry Juice?

You can enjoy the benefits of fresh cranberry juice no matter what time you drink it! However, if you’re drinking cranberry juice in the morning, try and wait at least an hour before brushing your teeth - juice can soften the enamel, and brushing right after can damage it further. 

Instead, if you wait for an hour, the enamel can harden again, and the risk of damaging your teeth is much reduced.

What Are the Benefits of Cranberry Juice for Women?

Cranberry juice has many benefits for females in particular, for example as discussed within the article it can help with post-menopausal health. This is due to the benefits of cranberry juice for both heart health and skin health, both of which are incredibly important after menopause, as heart issues increase. 

However, there aren’t many other gender-specific ways in which cranberry juice benefits females. Thankfully, all of the benefits mentioned above can be applicable to any gender, meaning no one has to miss out on the drink's beneficial properties.

What Are The Benefits of Cranberry Juice for Men?

Now that we have shared one example of how the drink benefits females, you might be wondering how cranberry juice benefits men specifically also, or if it does at all.

Thanks to the levels of antioxidants it contains, cranberry juice benefits males as it can help to prevent illnesses such as prostate cancer.

This is just one example of how cranberry juice benefits males, as it successfully lowers prostate-specific antigens known to cancer. A fact which has been supported by a 2016 piece of research, that concluded by drinking 1,500mg of cranberry juice prior to surgery reduced the growth rate of cancer among men. 

Of course, all the other aforementioned benefits of cranberry juice that we explored earlier also apply to men, including its ability to improve digestive function and prevent serious health conditions.

What Does The Cranberry Juice Diet Help With?

Now that you have gained a better understanding of how to answer ‘what does cranberry juice help with’, we can turn our attention to looking at the cranberry juice diet, and the impact it can have on your overall health. 

The cranberry juice diet involves incorporating the drink into your daily life 1-3 times every day, with the maximum amount of consumption acting as a detox for some individuals. By taking part in such a diet, you will maximise your chances of experiencing all of the above benefits of the drink.

However, with the benefits of the cranberry juice diet also comes a higher chance of experiencing the side effects. OriGym strongly recommends only taking part in this diet for intervals of 3 days. 

Taking part in the cranberry juice diet for longer periods of time could have serious knock-on effects with your health. 

What Happens If You Drink a Lot of Cranberry Juice?

If you drink too much cranberry juice, that’s when you can begin to experience side effects, including the ones mentioned above. 

The most commonly occurring cranberry juice side effects are stomach issues such as diarrhoea, cramps, and general discomfort, so be sure to limit your cranberry juice intake when possible. 

Whilst these side effects are prevalent in those who drink too much on a daily basis, by consistently drinking a moderate amount, cranberry juice will provide you with great benefits, so try and have a portion every day!

Before You Go!

Now that you know about all the benefits of drinking cranberry juice, you’ll be far less likely to pass by it in favour of orange juice on your next shopping trip! 

When faced with the question ‘is cranberry juice good for you?’, you can now answer with confidence that it is guaranteed to improve your health. Just be sure to enjoy all the benefits of fresh cranberry juice as part of a healthy, balanced diet, and don’t drink too much!
