What are the benefits of consuming celery juice for digestive health?

Celery Juice for Digestive Health

There is no high-quality evidence supporting celery juice specifically for digestive health, and whole celery would be preferable if you choose to consume it at all, as juicing removes beneficial fiber that aids digestive function.

Evidence Assessment

The available evidence does not support celery juice for digestive health:

Lack of Specific Evidence for Celery Juice

• No clinical guidelines or high-quality studies address celery juice for digestive conditions 1
• Research on celery focuses on seed extracts (not juice) for anti-inflammatory and metabolic conditions, not digestive health 2, 3, 4
• Celery seed extracts have shown anti-inflammatory and gastro-protective properties in animal models, but these findings cannot be extrapolated to celery juice 2, 5

Why Whole Celery is Superior to Juice

• Juicing removes dietary fiber, which is the primary mechanism by which plant foods benefit digestive health 1
• High-fiber diets promote beneficial gut bacteria (Bifidobacterium and Lactobacillus) and improve bowel movements, directly addressing constipation 1
• Dietary fiber produces short-chain fatty acids through colonic fermentation, which provide energy for colonocytes and modulate local immune responses 1
• Whole fruits and vegetables are consistently recommended over juices for digestive and overall health 1

Juice-Related Digestive Concerns

• Fruit and vegetable juices can cause digestive problems when consumed in excess due to carbohydrate malabsorption 1
• Fructose and sorbitol in juices present an osmotic load that can cause diarrhea, flatulence, bloating, and abdominal pain 1
• While some juices (prune, pear, apple) are used for constipation due to sorbitol content, this is a pharmacologic effect, not a health benefit 1

Clinical Recommendations

For General Digestive Health

• Consume whole celery as part of a high-fiber diet rich in fruits, vegetables, and whole grains 1
• Aim for five or more servings of fruits and vegetables daily to ensure adequate fiber and micronutrient intake 1
• A Mediterranean-style diet with whole plant foods has anti-inflammatory properties and supports gut microbiota diversity 1

For Specific Digestive Conditions

Constipation:

• Increase dietary fiber from whole foods, prebiotics (inulin, fructooligosaccharides), and resistant starch 1
• If using juice therapeutically, prune, pear, or apple juice may help due to sorbitol content, but whole fruit is preferable 1

Inflammatory Bowel Disease:

• Evidence suggests minimizing exposure to certain foods may help, but celery juice is not specifically studied 1
• Cereal grain-based fiber has shown benefits in ulcerative colitis, contrary to some exclusion diets 1

Important Caveats

• The probiotic and supplement market is largely unregulated, and health claims are often inappropriately transferred between products 6
• Celery seed extracts studied in research used standardized alcoholic extracts at specific doses (150-5,000 mg/kg in animal studies), which bear no relationship to drinking celery juice 2, 5
• Bioactive compounds in celery (phthalides, flavonoids, phenolic acids) vary significantly by cultivar and preparation method 3, 7
