Drinking fruit and vegetable juices can be a tasty way to get your daily dose of nutrients. Fresh juices provide vitamins, minerals, antioxidants, and plant compounds that can benefit your health. However, not all juices are created equal. Some contain high amounts of sugar and very little fiber, meaning their nutritional value is not as high. When choosing a healthy juice to drink daily, it’s important to consider ingredients as well as preparation methods.
Nutrients in Fresh Juices
Fresh fruit and vegetable juices retain most of the vitamins, minerals and plant nutrients of the whole produce. However, juicing removes the fiber content, which affects nutrient absorption. For example, without fiber to slow digestion, fruit sugars enter the bloodstream rapidly and can spike blood sugar levels. Juices made from vegetables like spinach, kale and carrots contain beneficial antioxidants and nutrients with less of a blood sugar impact.
Most Nutrient-Dense Juice Ingredients
The most nutrient-rich ingredients for fresh juices include:
- Dark leafy greens like spinach, kale, and chard
- Cruciferous vegetables like broccoli, cabbage, and bok choy
- Brightly colored fruits like berries, cherries, apples, oranges, kiwis
- Root vegetables like carrots, beets, sweet potatoes
- Citrus fruits like grapefruit, lemons, limes
- Ginger, turmeric, mint, parsley and other fresh herbs
These foods are packed with antioxidants, vitamins like A, C, and K, minerals like potassium and magnesium, and beneficial plant compounds.
Healthiest Juice Combinations
Creating juice combinations using vegetables as the base along with minimal amounts of low-sugar fruits can result in great nutrition and flavor.

Best Fruits to Use in Juices
While vegetables make up the majority of healthy juices, fruits add important nutrients and sweetness. Some of the best fruits to juice include:
|Apples||Vitamin C, antioxidants||Boost immunity, heart health|
|Berries||Vitamin C, antioxidants||Improve brain function|
|Citrus||Vitamin C, folate||Support immunity|
|Grapes||Vitamin C, K, antioxidants||Heart and brain health|
|Kiwis||Vitamin C, potassium||Immunity and heart health|
These fruits are lower in sugar than grapes, mangos, bananas and pineapple. They provide important vitamins, minerals and plant compounds with a lower glycemic impact.
Worst Fruits to Use in Juices
Some fruits are best consumed whole or in moderation rather than juiced. These include:
|Fruit||Sugar Content||Glycemic Index|
|Watermelon||9g per 100g||72 (high)|
|Pineapple||9g per 100g||66 (medium)|
|Mango||14g per 100g||60 (medium)|
|Grapes||16g per 100g||53 (medium)|
|Banana||12g per 100g||51 (medium)|
With juicing, the fiber is removed, spiking blood sugar. It’s best to eat these fruits whole and in moderation to reap their nutritional benefits.
Juicing Methods: Cold Press vs Centrifugal
Juicing method impacts the nutrient content of homemade juices. Cold press juicers crush fruits and veggies to squeeze out juice. Centrifugal juicers grind produce at high speeds, exposing juice to heat and oxygen.
Cold Press Juicers
- Retain nutrients better than centrifugal juicers
- Juices can be stored for up to 3 days
- Higher juice yields from produce
- Juices do not get foamy
- Quieter operation
- Faster juicing but some nutrients degrade
- Juices oxidize and should be consumed immediately
- Produce less juice yield
- Juices come out frothy
- Louder operation
For maximum nutrition, a slow cold press juicer is ideal. However, centrifugal juicers are more affordable options when starting out.
Tips for Making Healthy Juices at Home
Follow these best practices when making fresh juices at home:
- Wash all produce thoroughly before juicing.
- Aim for around 60-80% vegetables and 20-40% fruits.
- Juice produce with skins and peels when possible to get valuable nutrients.
- Use produce within a few days and store juices up to 3 days.
- If using a fast juicer, drink immediately before oxidation.
- Combine green leafy veggies like kale with sweeter fruits.
- Add fresh herbs like mint, parsley or basil for flavor.
- Include a slice of lemon or lime to help cut bitterness.
Potential Downsides of Juicing
While juices can be nutritious, there are some drawbacks to consider:
- Lower fiber content compared to whole fruits and vegetables
- Phytochemicals interact; juicing alters these plant compounds
- Sugar content spikes when fiber is removed
- Higher calorie intake is easy with juicing
- Important nutrients like protein and healthy fats are missing
- Not as filling as eating whole produce
To get the most out of juicing, rotate it with whole fruits and veggies instead of relying on it exclusively. And limit fruit-heavy juices to keep sugar in check.
The Bottom Line
Drinking fresh juices made primarily from vegetables with some fruits and herbs can provide beneficial vitamins, minerals, antioxidants and phytochemicals. Focus on produce like leafy greens, carrots, beets and citrus fruits. Limit high-sugar fruits like grapes, bananas, mangos or pineapples. And vary your intake by also eating whole fruits and veggies. With a well-balanced approach, enjoying fresh homemade juices can be healthy part of your diet.
