Does green juice cleanse your stomach?
Green juices have become increasingly popular in recent years, with many people drinking them for their potential health benefits. Some proponents claim that green juices can “cleanse” or “detox” your body, including your digestive system. But is there any truth to this? Let’s take a closer look at whether green juice can actually cleanse your stomach.
What is a Green Juice Cleanse?
A green juice cleanse typically involves consuming only fresh, cold-pressed green vegetable juices for a period of time – usually between 3 and 7 days. Some cleanses also allow herbal teas. The purpose is to flood your body with vitamins, minerals, and antioxidants while eliminating processed foods, animal products, and other potential toxins.
Common ingredients in green juices include leafy greens like spinach, kale, chard, and collard greens. Cucumber, celery, parsley, ginger, lemon, and green apples are also popular additions. The juices are made by running the vegetables through a cold-press juicer, which extracts the liquid without applying heat that could destroy nutrients.
Proposed Benefits of a Green Juice Cleanse
Advocates claim that green juice cleanses can provide many benefits, including:
- Giving your digestion a rest by eliminating solid foods
- Increasing your intake of antioxidants and phytonutrients
- Improving energy levels
- Enhancing immunity
- Reducing inflammation
- Cleansing and detoxifying the body of toxins
- Improving skin appearance
- Promoting weight loss
- Regulating appetite hormones like leptin and ghrelin
However, many of these proposed benefits lack solid scientific evidence. So does green juicing really “cleanse” the stomach as claimed?
Does Green Juice Cleanse the Stomach?
When considering whether green juices cleanse your stomach, it helps to first understand a bit about your digestive system:
- The stomach’s main roles are to store food after eating, mix food with digestive juices, and slowly empty its contents into the small intestine.
- Gastric acid and pepsin break down proteins, while the stomach muscles churn food into chyme.
- The stomach lining protects itself from acid with a mucosal barrier.
- Disruption of the stomach can lead to conditions like gastritis, ulcers, and gastroesophageal reflux disease (GERD).
Green juice cleanse advocates believe that flooding your system with liquid nutrients gives your digestion a break while removing toxins and improving gut health. However, there is little scientific evidence that green juices actually “cleanse” the stomach.
Potential Benefits for Stomach Function
Some potential benefits of green juicing for stomach function include:
- Increased nutrient absorption – Liquids are easier to digest than solid foods and may allow for efficient absorption of vitamins and minerals.
- Phytonutrients – Green juices provide plant compounds like polyphenols that may help protect the stomach lining.
- Probiotics – Juices made with fermented foods like sauerkraut may contain probiotics to support gut health.
- Reduced acid load – Replacing high-acid foods with alkaline green juices may help reduce stomach acid levels.
Potential Drawbacks of Green Juice Cleanses
However, there are also some potential drawbacks of green juice cleanses for your stomach:
- Lack of protein and fat – Not consuming solid food for extended periods can lead to inadequate intake of protein, fat, and fiber.
- Blood sugar spikes – The high glycemic load of fruit-based green juices can cause blood sugar spikes and crashes.
- Loss of electrolytes – Fasting with only juices may result in low sodium and other important minerals.
- Caffeine – Some juices contain coffee, matcha, or other caffeine sources that may irritate the stomach.
The Bottom Line
While green juices provide a concentrated dose of vitamins and minerals, there is little evidence that they actually “cleanse” or detoxify the stomach. In fact, drastically reducing your solid food intake could disrupt your stomach function in the long run.
Here is a summary of the bottom line on green juice cleanses for stomach health:

While green juices can be a healthy part of your diet, relying on them alone for extended “cleanses” is not scientifically supported. The best approach is to eat a balanced diet with plenty of whole fruits, vegetables, lean proteins, healthy fats, and fiber.

Should You Do a Green Juice Cleanse?
Green juice cleanses are generally safe for most healthy people for 1-3 days. However, you may experience side effects like:
- Hunger and food cravings
- Headaches
- Fatigue and weakness
- Dizziness
- Nausea
- Irritability
Longer juice fasts of 5-7 days are not recommended, especially without medical supervision. You may also want to avoid green juice cleanses if you have:
- Diabetes
- Gastrointestinal issues
- Eating disorders
- Nutrient deficiencies
- Low blood pressure
- Kidney disease
- Pregnancy or breastfeeding
For most people, the best way to reap the benefits of green juices is to include them as part of a healthy, balanced diet. Focus on smoothies and juices rich in vegetables, fruits, herbs, and spices that work for your taste preferences and health goals.
The Takeaway
While green juices contain a concentrated dose of nutrients, there is little evidence that they “cleanse” or detoxify the stomach. Short 1-3 day green juice cleanses are likely safe for most people but come with possible side effects. For optimal stomach health, focus on eating a balanced diet with plenty of whole fruits, vegetables, fiber, protein, and healthy fats.
Incorporate green juices as a fresh, phytonutrient-rich addition to your routine rather than a complete fast. And be sure to consult your healthcare provider before attempting a green juice cleanse, especially if you have any medical conditions.
