Support Your Knees With Nutrition and Movement
Your knees help you walk, climb stairs, and stay active every day. While no single food can cure arthritis or rebuild damaged cartilage, a balanced diet and regular physical activity can support joint health and overall mobility.
1. Nutrients in Oranges and Red Onions
Oranges
Oranges provide:
- Vitamin C: Supports normal collagen production, which is important for cartilage, tendons, ligaments, and other connective tissues.
- Antioxidants: Naturally occurring compounds that are part of a healthy diet.
- Water and fiber: Contribute to hydration and digestive health.
Red Onions
Red onions contain:
- Quercetin: A naturally occurring plant compound.
- Sulfur-containing compounds: Responsible for much of their flavor and aroma.
- Fiber: Supports healthy digestion.
- Low calories: An easy way to add flavor and vegetables to meals.
Both foods fit well into an eating pattern rich in fruits and vegetables, such as the Mediterranean-style diet.
2. Other Foods That Support Joint Health
A variety of nutrient-rich foods can help support overall musculoskeletal health, including:
- Fatty fish: Salmon, sardines, trout, and mackerel provide omega-3 fats.
- Leafy greens: Spinach, kale, and broccoli provide vitamins and minerals.
- Nuts and seeds: Walnuts, chia seeds, and flaxseeds contain healthy fats and fiber.
- Berries: Blueberries, strawberries, and raspberries provide antioxidants.
- Olive oil: A source of heart-healthy monounsaturated fats.
- Protein-rich foods: Beans, lentils, eggs, dairy, poultry, fish, and lean meats help maintain muscle, which supports the joints.
3. Habits That Help Support Healthy Knees
Strong muscles and healthy lifestyle habits play a major role in knee function.
Consider these evidence-based strategies:
- Strengthen the muscles around your knees: Exercises that target the quadriceps, hamstrings, glutes, and calves help support knee stability. A physical therapist can recommend a program that fits your needs.
- Choose low-impact activities: Walking, cycling, swimming, and water aerobics can help maintain joint mobility while reducing stress on the knees.
- Maintain a healthy weight: Even modest weight loss can reduce stress on the knee joints in people who are overweight.
- Stretch regularly: Gentle flexibility exercises may help maintain range of motion.
- Wear supportive footwear: Proper shoes can improve comfort during daily activities.
- Stay hydrated: Adequate hydration supports overall health and normal joint function.
