Colorful juice charts often claim that certain fruit and vegetable blends can “cure” conditions like diabetes, asthma, kidney stones, or depression. While fresh juices can be nutrient-rich and supportive of overall health, they are not cures for medical diseases.
Let’s break down the most common juice claims and what science actually says.
🥕 Can Juice Really Cure Disease?
Short answer: No single juice can cure a medical condition.
However, fruits and vegetables contain vitamins, minerals, antioxidants, and plant compounds that may support:
Immune function
Digestion
Heart health
Hydration
Inflammation balance
Juice works best as part of a balanced diet — not as a replacement for medical treatment.
