Have you ever felt that sharp pain when climbing stairs? That stiffness that forces you to rise slowly from the couch? If you’re over 45, chances are your knees no longer respond the way they used to. You walk more carefully, avoid squatting, and even the weather seems to affect how your joints feel.
But what if a 97-year-old orthopedic doctor claims that a single natural food can help support knee cartilage regeneration in as little as 24 hours?
It sounds unbelievable. Yet what you’re about to read may completely change how you think about joint aging.
The Silent Problem Affecting Millions
Cartilage is the body’s natural shock absorber. It’s the smooth, flexible tissue that prevents bones from rubbing against each other. Over time — especially with poor diet, excess weight, or inactivity — this tissue begins to wear down.
When cartilage deteriorates, joints lose their fluid movement. What was once effortless becomes stiffness, cracking, and often pain. This is how osteoarthritis develops, one of the leading causes of disability worldwide.
According to public health data, over 40% of adults above 50 experience some degree of joint degeneration, particularly in the knees.
But there is hope — and it comes from a surprisingly simple place: your kitchen.
The Story Behind the Discovery
Dr. Ernesto Salazar, a Mexican orthopedic surgeon with over 70 years of medical practice, has always believed that nutrition is the foundation of bone and joint health. At 97, he still walks independently, without a cane, and with remarkable mental clarity.
In an interview, he shared his “simplest secret”:
“It’s not about pills or expensive therapies. Nature has already given us what we need. We just have to use it.”
That secret, according to him, is one food many people already have but underestimate:
👉 Natural collagen from bone broth.
The One Food That Could Change Everything: Bone Broth
Yes, that traditional recipe your grandmother used — rich in aroma and comfort — hides a powerful benefit.
Bone broth, made by slowly simmering beef, chicken, or fish bones for hours, releases essential compounds that support joint repair.
It naturally contains:
Type II Collagen – crucial for cartilage strength and elasticity
Glycine & Proline – key amino acids for connective tissue structure
Glucosamine & Chondroitin – known for joint lubrication and repair
Dr. Salazar explains that when consumed warm, bone broth allows easy absorption of these nutrients, helping nourish cartilage and strengthen damaged tissue.
Why Collagen Matters So Much for Your Knees
Think of your joints like door hinges that move smoothly thanks to a lubricating gel. That “gel” is largely made of collagen.
After age 35, collagen production drops significantly. Friction increases. Movements become painful. Tissues wear down.
The natural collagen in bone broth acts as internal reinforcement, supporting the protective layer of your joints. It’s not a miracle cure, but its regenerative potential is gaining serious attention.
A Real-Life Testimonial
Ana María, 63, from Guadalajara, could barely climb stairs without pain. After trying supplements and creams with little success, she followed Dr. Salazar’s approach.
She began drinking one cup of homemade bone broth daily.
After 2 weeks: morning stiffness reduced
After 1 month: she could walk short distances without discomfort
“I thought it was coincidence, but my body feels stronger,” she says with a smile.

“Never underestimate what nature can do. The body doesn’t need miracles — it needs real nutrients.”
Conclusion: The Power of Simplicity
You don’t need expensive supplements or painful treatments to care for your knees. Sometimes, the most powerful remedies are the oldest ones.
Bone broth, rich in collagen and essential minerals, may be the small change that transforms your mobility, energy, and overall well-being.
Before reaching for another painkiller, try preparing a natural broth. Give your body what it needs to repair itself — from the inside, patiently.
As Dr. Salazar puts it:
“Walking without pain is not a luxury. It’s a right that nature can still give back.”

Could a Traditional Food Hold the Key to Healthier Knees? Experts Highlight Bone Broth Benefits
For many adults over 45, simple movements like climbing stairs or rising from a chair can bring discomfort. Stiff knees, occasional cracking, and persistent soreness may make daily activities a careful task. Weather changes can intensify the discomfort, leaving some to wonder if joint decline is inevitable.
Yet, some experts believe a natural dietary approach may help restore knee function and support cartilage health—sometimes surprisingly quickly. One 97-year-old orthopedic doctor claims that a single food could support cartilage regeneration in as little as 24 hours. While this may sound extraordinary, its scientific and nutritional basis is worth exploring.
The Hidden Challenge Affecting Millions
Cartilage serves as the body’s natural shock absorber. This smooth, flexible tissue prevents bones from grinding against each other, ensuring pain-free movement. Over time, cartilage begins to deteriorate due to aging, poor nutrition, excess weight, or a sedentary lifestyle.
When cartilage wears down, joint mobility declines. Simple movements become stiff and uncomfortable, often accompanied by cracking sounds. This process is central to osteoarthritis, a condition considered one of the leading causes of disability worldwide.
Data indicate that more than 40% of adults over 50 experience some degree of joint degeneration, particularly in the knees. Many affected individuals initially dismiss stiffness as a normal part of aging, unaware that lifestyle and diet can influence the progression of joint problems.
While pharmaceutical treatments and physical therapies exist, some health experts point to simpler, natural solutions that can complement conventional care—and they often originate in the kitchen.
A Lifetime of Insight: Dr. Ernesto Salazar
Dr. Ernesto Salazar, a Mexican orthopedic surgeon with over 70 years of experience, has dedicated his life to understanding joint and bone health. Now 97, he continues to walk independently without assistance and maintains remarkable cognitive clarity. His decades of clinical observation have led him to a striking conclusion: nutrition plays a central role in maintaining joint integrity.
In an interview, Dr. Salazar emphasized:
“It’s not about pills or expensive therapies. Nature has already given us what we need. We just have to use it.”
According to Dr. Salazar, the key to supporting joint health is a food many people already have at home but often overlook: bone broth.
Bone Broth: A Nutrient Powerhouse
Bone broth has been a traditional staple in many cultures for centuries. Made by simmering bones for several hours, this humble food is packed with compounds that may support joint health. The slow cooking process releases nutrients vital for cartilage and connective tissue repair, including:
Type II Collagen: Essential for maintaining cartilage strength and elasticity
Glycine and Proline: Amino acids critical for connective tissue structure
Glucosamine and Chondroitin: Known for joint lubrication and repair
Dr. Salazar notes that consuming bone broth warm enhances nutrient absorption, providing the body with the building blocks needed to strengthen damaged cartilage. While it is not a miracle cure, its regenerative potential is increasingly recognized by nutritionists and orthopedic specialists.
Why Collagen Is Vital for Joint Health
Collagen functions much like the lubricating gel in a hinge, allowing smooth, pain-free movement. As individuals age, natural collagen production declines, often beginning around age 35. Reduced collagen increases friction within joints, leading to stiffness, discomfort, and progressive tissue wear.
The collagen and other compounds in bone broth work to reinforce this protective layer. Consistent consumption may support cartilage maintenance, improve joint mobility, and reduce the risk of inflammation-related deterioration.
Real-World Evidence
Ana María, 63, from Guadalajara, experienced severe knee stiffness that made stair climbing difficult. After years of trying various supplements and topical treatments without relief, she adopted Dr. Salazar’s advice and began drinking one cup of homemade bone broth daily.
After two weeks: Morning stiffness significantly improved
After one month: She could walk short distances comfortably
“I thought it was coincidence, but my body feels stronger,” she shared, highlighting the potential benefits of incorporating nutrient-rich, natural foods into daily routines.
Six Benefits of Bone Broth for Joints
