Eating Right Nourishes Joints. Eating a healthy diet is good for your joints, because it helps build strong bones and muscles. … You also need vitamin D to keep your bones and joints in good health. Vitamin D helps your body absorb calcium from the foods you eat.
You and Your Joints
A joint is the connection between two bones. Joints and their surrounding structures allow you to bend your elbows and knees, wiggle your hips, bend your back, turn your head, and wave your fingers to say bye-bye.
Smooth tissue called cartilage and synovium and a lubricant called synovial fluid cushion the joints so bones do not rub together. But increasing age, injury,or carrying too much weight can wear and tear your cartilage. This can lead to a reaction that can damage your joints and lead to arthritis.
