Does juicing break down nutrients?

Juicing has become more and more popular over the years. Many people have turned to juicing as a way to improve their health and get the nutrients they need in a quick and easy way. But the question arises, does juicing break down nutrients?

In this blog post, we will discuss whether juicing affects the nutrient content of fruits and vegetables and the potential benefits and drawbacks of juicing.

Nutrient Loss in Juicing

Studies have shown that juicing can lead to the loss of some nutrients in fruits and vegetables. While juicing can provide an easy and convenient way to consume a variety of fruits and vegetables, it can also break down important nutrients found in these foods.

When you juice fruits and vegetables, you are separating the juice from the pulp or fiber. Fiber is an important part of fruits and vegetables, and it can help slow down digestion and reduce blood sugar spikes. It has also been shown to aid in weight loss and lower the risk of heart disease, diabetes, and certain types of cancer.

Juicing removes this fiber, which can lead to a decrease in nutrient content. Fiber helps protect the nutrients from oxidation and degradation. When fiber is removed, the nutrients in the juice are exposed to oxidizing agents, which can break them down and reduce their nutritional value.

Certain nutrients are more easily destroyed during the juicing process, such as Vitamin C. This essential nutrient is found in citrus fruits, berries, kiwi, and many vegetables. It is sensitive to heat and air, so when juice is made, Vitamin C is often destroyed or lost through exposure to air.

Potential Benefits of Juicing

Despite the potential nutrient loss during the juicing process, there are still some benefits to incorporating fresh juice into your diet.

Firstly, juicing can help you consume a larger variety of fruits and vegetables that you may not typically eat. It provides a more concentrated form of vitamins, minerals, and antioxidants than you would typically get from eating the whole fruit or vegetable.

Juicing can also be a convenient way to consume nutrients on the go. Busy schedules may make it difficult to sit down and eat a full meal of fruits and vegetables. Instead, it can be easier to whip up a quick juice and get all the nutrients you need in one go.

Finally, juicing may be helpful for those who have digestive issues. Some individuals find it difficult to digest large amounts of fruits and vegetables, and juicing can help render the nutrients more easily digestible.

Drawbacks of Juicing

Despite the potential benefits, there are also some drawbacks to juicing.

When juicing, you can end up consuming a lot of sugar. Fruits in particular are high in sugar, and when they are juiced, the sugar is released in a concentrated form. This can lead to blood sugar spikes and is not recommended for those with diabetes or other blood sugar issues.

Furthermore, juicing can be expensive. Fresh produce can be costly, and the juicing machines themselves can cost hundreds of dollars. This is not feasible for everyone, especially those on a tight budget.

Finally, juicing can be time-consuming. Not only does it take time to clean and prepare the produce, but it can also be difficult to clean the juicer after use.


In summary, juicing can lead to the loss of some key nutrients found in fruits and vegetables, due to the removal of fiber during the juicing process. While juicing can be a convenient way to consume a variety of nutrients, it can also be expensive and time-consuming.

If you do choose to juice, try to consume more vegetables than fruits to reduce sugar intake. Additionally, incorporating fresh fruits and vegetables into your meals can be just as beneficial, and ensures that you consume all the nutrients and fiber that these foods have to offer.


Do you lose nutrients when juicing?

Juicing has been a popular health trend for many years now, and it’s often touted for its ability to provide quick and easy access to important vitamins and minerals. However, the question arises whether juicing can cause a loss of nutrients from the fruits and vegetables being juiced. In short, the answer is both yes and no, as juicing can affect the nutrient content of fruits and vegetables in a few different ways.

When fruits and vegetables are juiced, their fibers are removed in the process, which can lead to a reduction in nutrient content. Fiber is an important nutrient that plays many roles in the body, including regulating blood sugar and cholesterol levels, promoting healthy digestion, and helping you feel full. When fruits and vegetables are juiced, the liquid that is extracted contains most of the vitamins, minerals, and phytonutrients found in the fruit, but the fiber is left behind. This means that while the juice can still be beneficial for your health, it won’t have the same nutritional profile as the whole fruit or vegetable.

Furthermore, the juicing process can also cause some nutrients in fruits and vegetables to break down or be destroyed. For example, vitamin C is a sensitive nutrient that is easily oxidized when exposed to air, and therefore may be lost during the juicing process. Similarly, some enzymes and amino acids in fruits and vegetables may be affected by the heat generated during the juicing process, leading to a loss of these important nutrients.

Finally, some types of juicing methods, such as high-speed centrifugal juicers, can generate heat and friction that may further reduce nutrient content. On the other hand, low-speed masticating juicers may be a better option, as they operate at a slower speed and generate less heat and friction, which can help to preserve more of the nutrients in the juice.

While juicing can provide a quick and easy way to access important vitamins and minerals in fruits and vegetables, it’s important to remember that the fiber content of these foods is also important for overall health and wellbeing. Additionally, the juicing process itself can cause some nutrients to be lost, though this may depend on the specific type of juicer being used. incorporating fresh fruits and vegetables into your diet in a variety of ways, including juicing, can help you meet your nutrient needs and improve your overall health and wellbeing.

What are the downsides of juicing?

Juicing is a popular trend for individuals who are looking for a way to add more nutrients and vitamins to their diet. As the practice of juicing has increased in popularity over the years, the question of whether juicing has any drawbacks has been raised. While juicing can be beneficial for some individuals, such as those who have difficulty eating enough fruits and vegetables or are unable to properly digest whole foods, it is important to consider the downsides of juicing as well.

Firstly, one of the primary downsides of juicing is that a juicing machine leaves nutrient-rich and fiber-rich skin and pulp behind. Without the fruit fiber, your body absorbs the fructose sugar more easily, which can upset blood sugar levels. This means that the juice you are consuming may be high in sugar and low in fiber, which can cause a spike in blood sugar levels.

Secondly, juice made with fruit has a high calorie count. While fruit is known for its plethora of vitamins and nutrients, it is also high in natural sugars that can add up calorie-wise. Additionally, many individuals might overlook the caloric content of their juices by assuming they are healthy and low in calories, which can contribute to over-consumption and weight gain.

Finally, juicing can be expensive. Sourcing organic produce can drive up the cost, plus the machinery and tools required for juicing may also come with an extra cost. Furthermore, achieving optimal health requires a well-balanced diet, which may require buying a variety of fruits and vegetables which can add up.

Juicing can be a convenient way to add more fruits and vegetables to your diet, but it is important to understand the potential downsides as well. Those who are looking to incorporate juicing into their daily routine should be aware of the calorie content of their juices, the potential impact on blood sugar levels, and the cost of sourcing and using equipment necessary for juicing.

What vegetables should not be juiced?

Juicing is a popular way to consume fruits and vegetables in a convenient and easy-to-digest format. However, not all fruits and vegetables are suitable for juicing, as some may cause adverse effects when consumed in large quantities. In this regard, it is essential to know which vegetables you should avoid juicing, as they may be harmful to your health.

One vegetable that should be avoided when juicing is spinach. While spinach is known to be a nutritional powerhouse that is rich in vitamins and minerals, it contains oxalates, which can lead to the formation of kidney stones. Oxalates are also found in other foods, such as bananas, mangoes, and cauliflower. While it is still safe to consume these foods in moderation, it is not recommended to juice them regularly.

Another vegetable that should be avoided when juicing is raw kale. Raw kale contains goitrogens, which can interfere with thyroid function when consumed in large amounts. Goitrogens are also found in other cruciferous vegetables such as broccoli and cabbage, but cooking them can reduce their goitrogenic effect.

It is worth noting that while some vegetables may not be suitable for juicing, they can still be included in your diet in other ways. For example, instead of juicing raw kale, you can roast or steam it to minimize its goitrogenic effect. Additionally, if you still want to add spinach to your diet, you can cook it first to reduce its oxalate content.

Some vegetables should be avoided when juicing, as they may cause adverse effects. Spinach and raw kale are two vegetables that should not be juiced regularly due to their oxalate and goitrogen content, respectively. It is essential to consume these vegetables in moderation and find other ways to include them in your diet without compromising your health.
