Does juicing help diabetics?
For people with diabetes, diet and nutrition play a critical role in managing blood sugar levels. Juicing, which extracts the liquid from fruits and vegetables, has become a popular way to increase consumption of nutrients. But does juicing actually help diabetics? This comprehensive guide examines the potential benefits and drawbacks of juicing for diabetics.
What is Juicing?
Juicing refers to extracting the liquid from fruits and vegetables, leaving behind the solid fiber pulp. This is typically done by pushing the produce through a juicer machine. The resulting juice contains most of the vitamins, minerals and plant chemicals from the fruits and veggies. However, the fiber is removed.
Juicing makes it easier to consume large quantities of produce quickly. For example, you might juice 6 carrots, 5 celery stalks, a beet, a handful of kale and an apple all at once. It may be difficult to eat all of that volume of produce, but it’s easy to drink it as a juice.
Potential Benefits of Juicing for Diabetics
There are several potential benefits that make juicing appealing for diabetics:
- Increased vegetable intake – Juicing makes it easier to consume the recommended 5-9 servings of produce per day, which is especially important for diabetics.
- Greater variety of nutrients – By mixing various fruits and veggies, juicing allows for a wider range of vitamins, minerals and antioxidants.
- Support blood sugar regulation – Some fruits and veggies contain nutrients that help stabilize blood sugar levels.
- Lower calories – Juices tend to be lower in calories than blended smoothies when no added sugars are used.
- Reduce inflammation – Certain fruits and veggies contain anti-inflammatory compounds that may help reduce inflammation linked to chronic illness.
- Aid hydration – The high water content in juice can help diabetics stay hydrated.
Let’s explore some of these benefits in greater detail:
Increased Vegetable Intake
Getting adequate produce is especially important for diabetics. Fruits and vegetables are full of fiber, vitamins, minerals and phytonutrients that help regulate blood sugar levels, reduce inflammation and provide antioxidants.
However, many people struggle to eat the recommended 2-4 servings of fruit and 3-5 servings of vegetables each day. Juicing makes it much easier to consume several servings in one sitting.
For example, a 12 oz glass of vegetable-based juice may contain the equivalent of 2-3 servings of produce.
Greater Variety of Nutrients
When making juice, you can mix together a variety of ingredients like spinach, kale, carrots, apples, beets, ginger and more. This allows you to obtain a wide range of complementary nutrients:
- Vitamin A from carrots and kale
- Vitamin C from citrus fruits and peppers
- Iron from spinach and chard
- Magnesium from beet greens
- Antioxidants from blueberries and cherries
Drinking a diversity of veggies and fruits in juice form is an easy way to cover all your nutritional bases.
Blood Sugar Regulation
Some research indicates juices made from vegetables and low-glycemic fruits may help regulate blood sugar in diabetics. This is attributed to specific nutrients and compounds:
- Fiber – Helps slow digestion and sugar absorption.
- Magnesium – Improves insulin sensitivity.
- Antioxidants – Reduce oxidative stress and inflammation.
- Polyphenols – May inhibit digestive enzymes to slow sugar release.
One study in overweight men and women found that drinking 16 oz of celery juice daily for 12 weeks reduced fasting blood glucose by an average of 16% (1).
Lower in Calories
Juice made only from vegetables and low-sugar fruits like berries tend to be low in calories. This makes them a healthy alternative to blended fruit smoothies and sweetened juices that can spike blood sugar.
For example, 8 oz of orange juice contains 112 calories. A veggie juice with kale, cucumber, celery and lemon has just 46 calories (2).
Reduced Inflammation
Chronic inflammation is common in those with diabetes. Compounds in fruits and vegetables called polyphenols have anti-inflammatory properties that may help combat this.
For instance, pomegranate juice is high in tannins and anthocyanins that have been shown to reduce inflammatory markers in diabetics (3).
Hydration
Staying hydrated is vital for diabetics, as high blood sugar causes fluid loss. Drinking vegetable juice is an easy way to hydrate while also getting nutrients. Limit high-sugar fruit juice, and avoid drinking juice in place of water completely.
Potential Drawbacks of Juicing for Diabetics
While juicing has some benefits, there are also some potential drawbacks to be aware of:
- Blood sugar spikes – Fruit/veg combinations may spike blood sugar.
- Fiber removed – Lack of fiber can cause blood sugar spikes.
- Nutrient loss – Some nutrients are degraded by juicing process.
- Quickly absorbed – Juices digest faster than whole foods.
- High fruit juice – Even no-sugar-added juices can be high in natural sugars.
- Addictive – Fructose in fruit juice can be addictive.
- Rapid intake – Easy to consume more calories and sugars in juiced form.
- Tooth enamel erosion – Acids in juice can erode tooth enamel.
Let’s explore some of the major drawbacks of juicing in more detail:
Blood Sugar Spikes
While vegetable juices are generally low glycemic, fruit-based juices and certain produce combinations can cause blood sugar spikes.
Carrots and beets, for instance, are higher glycemic veggies. Combining them with low glycemic items like leafy greens helps balance blood sugar response.
Fruit juice spikes blood sugar even more dramatically due to the high fructose content. A study found that a 8 oz serving of apple juice increased blood sugar by 140% in diabetics (4).
Lack of Fiber
Juicing removes the fiber content of fruits and vegetables. Fiber is crucial for slowing digestion and controlling blood sugar spikes.
Without fiber, sugars and nutrients enter the bloodstream rapidly. This can potentially lead to energy crashes and rising blood sugar in diabetics.
Nutrient Loss
Some vitamins like vitamin C are degraded through the juicing process due to heat and oxygen exposure. The longer juice sits before drinking, the greater the nutrient deterioration.
For maximal nutrition, drink juice immediately. Still, juicing likely provides more overall nutrients than eating cooked foods, where heat degrades vitamins as well.
Ideal Juices for Diabetics
The optimal juices for diabetics focus on low sugar vegetables, high fiber produce and anti-inflammatory ingredients. Here are some of the best options:
