Juicing has become increasingly popular for its ability to quickly provide nutrients from fruits and vegetables. However, not all produce is suitable for juicing. Knowing what fruits and vegetables should not be juiced is essential for getting the best nutritional results and avoiding unpleasant textures or potential health risks.
Benefits of Juicing: What You Need to Know Before Juicing
Juicing extracts the liquid part of fruits and vegetables, preserving essential vitamins and minerals while eliminating fiber. This can be beneficial, especially for those seeking to boost nutrient intake quickly. Many juice advocates appreciate the convenience and the ability to consume multiple servings of fruits and vegetables in one glass.
However, before incorporating this into your lifestyle, it is essential to consider what fruits and vegetables should not be juiced to avoid making unhealthy or ineffective juice blends.
Fruits You Should Not Juice: What Fruits Should Not Be Juiced
1. Bananas:
Bananas are delicious, but they don’t work well for juicing due to their low water content. Instead of producing juice, bananas create a mushy pulp that can clog juicers. If you want the nutritional benefits of bananas, it’s better to blend them in smoothies.
2. Avocados
Known for their healthy fats, avocados are another fruit that should not be juiced. Their creamy texture is perfect for smoothies, but they don’t contribute any liquid to juice. Avocados work best when blended with other ingredients to add richness to smoothies.
3. Figs
Figs are fiber-rich but contain little water, making them unsuitable for juicing. They can easily turn into a thick pulp rather than producing a refreshing juice.
4. Berries (Raspberries, Strawberries)
While full of nutrients, raspberries and strawberries are low in water and high in seeds and pulp, leading to an inefficient juicing process. Consider blending them in a smoothie or adding them to juices after juicing other fruits.
5. Rhubarb
Rhubarb contains oxalic acid, which can be harmful when consumed in large quantities. This tart vegetable is best used in cooking or baking rather than juiced, as it poses potential health risks.
Vegetables You Should Avoid Juicing
1. Potatoes
Potatoes are high in starch and contain solanine, a toxic compound when eaten raw. Juicing raw potatoes is not recommended due to their unappealing taste and potential toxicity. Cooked potatoes, however, are a nutritious option in other forms.
2. Eggplant
Eggplant also contains solanine and can cause digestive issues if juiced raw. Cooking eggplant reduces the solanine content, making it safer to eat, but it’s not ideal for juicing.
3. Broccoli
Though healthy, broccoli is tough to digest when consumed raw in large amounts, such as in juice. Juicing broccoli can lead to bloating or digestive discomfort, so it’s better to eat it cooked or lightly steamed.
4. Kale (in large quantities)
Kale is a popular ingredient in green juices, but consuming it in large quantities can disrupt thyroid function due to its goitrogenic properties. While small amounts are healthy, over-juicing kale may lead to health issues over time.
5. Cassava
Cassava contains cyanogenic glycosides, which release toxic cyanide when consumed raw. Avoid juicing raw cassava to prevent toxicity, and always cook it before consumption.
Why Certain Fruits and Vegetables Should Not Be Juiced
There are several reasons why specific fruits and vegetables don’t work well for juicing:
- Low Water Content: Fruits like bananas, figs, and avocados lack enough water to produce juice. Instead of liquid, they create a thick, pasty consistency.
- Toxins and Antinutrients: Some vegetables, such as eggplant and potatoes, contain toxins like solanine, which are harmful when consumed raw. Others, such as rhubarb and cassava, can release harmful substances if juiced raw.
- Digestive Concerns: Vegetables like broccoli can cause bloating or digestive discomfort when juiced raw.
It’s essential to understand what fruits and vegetables should not be juiced to avoid negative effects and improve your juicing experience. For instance, the high oxalic acid content in rhubarb and raw leafy greens can lead to kidney stones if consumed regularly in juice form.

Combining Fruits and Vegetables in Juices: The Pros and Cons
Some juicing enthusiasts love to mix fruits and vegetables for enhanced flavor and nutrition, but this combination can have pros and cons.
Pros:
- Nutritional Variety: Mixing fruits and vegetables provides a range of nutrients.
- Improved Taste: Adding fruit to vegetable juice enhances flavor, making green juices more palatable.
Cons:
- Digestive Issues: Fruits and vegetables digest at different rates, leading to potential bloating or discomfort when combined in large amounts.
- Sugar Content: Combining high-sugar fruits with vegetables can increase the calorie content of your juice.
Health Risks of Juicing Certain Fruits and Vegetables
When juicing, it’s crucial to know what fruits and vegetables should not be juiced to avoid health risks.
Oxalic Acid in Leafy Greens
Oxalic acid, found in leafy greens like spinach and chard, can lead to the formation of kidney stones if consumed in large quantities. While green juices are popular, it’s best to balance high-oxalate greens with other low-oxalate vegetables.
Solanine Toxicity
Vegetables from the nightshade family, including eggplant and raw potatoes, contain solanine, which can be toxic in large amounts. Solanine poisoning can cause nausea, diarrhea, and even neurological symptoms, making it essential to avoid juicing nightshades raw.
High Sugar in Fruits
Many fruits, such as grapes, mangos, and pineapples, are high in natural sugars. Juicing them removes the fiber, which leads to rapid absorption of sugar and can spike blood glucose levels. This is particularly concerning for individuals with diabetes or those watching their sugar intake.
Healthier Alternatives to Unsafe Juicing Ingredients
If you’re looking for safer and more effective alternatives, here are some fruits and vegetables that juice well and contribute to a healthy, balanced diet:
- Cucumber: High in water, cucumber is a great addition to any juice.
- Celery: Low in calories and water-rich, celery adds flavor and nutrients without overwhelming the juice.
- Spinach: Though high in oxalates, spinach is safe in moderation. Combine it with other vegetables for a balanced green juice.
These options provide hydration and nutrients without the risks associated with more problematic ingredients.
FAQs
Can I juice bananas?
No, bananas are not suitable for juicing due to their low water content. They work better in smoothies.
Is juicing raw potatoes safe?
No, raw potatoes contain solanine, which can be harmful. Always cook potatoes before consuming them.
Can I juice kale every day?
It’s not recommended to juice kale in large amounts daily, as it contains goitrogens that can disrupt thyroid function. Moderation is key.
Conclusion
In conclusion, knowing what fruits and vegetables should not be juiced can enhance the benefits of juicing while minimizing health risks. By avoiding low-water-content fruits, starchy vegetables, and certain toxic ingredients, you can create delicious and healthy juices that support your overall well-being.
