What you eat gives your body the raw materials to build and maintain cartilage, and it strongly influences the low-grade inflammation that drives joint pain. No single food is a cure, but a joint-friendly pattern of eating — kept up over time — genuinely supports how your knees and joints feel and function.

Nutrients your joints depend on

  • Protein supplies the amino acids your body uses to build collagen and repair tissue. Include a source at each meal — eggs, fish, poultry, dairy, legumes.
  • Vitamin C is essential for making collagen. Find it in citrus, guava, peppers, strawberries, and tomatoes.
  • Omega-3 fatty acids help calm inflammation. Oily fish (salmon, sardines, mackerel) two to three times a week is ideal; walnuts and flaxseed help too.
  • Vitamin D and calcium support the bone beneath the cartilage. Sunlight, dairy, eggs, and fortified foods contribute.
  • Polyphenols and antioxidants from colourful vegetables, olive oil, berries, and green tea protect joint tissue from oxidative stress.

A simple joint-friendly plate

Aim to fill half your plate with vegetables and fruit, a quarter with quality protein, and a quarter with whole grains, plus a little olive oil. This "Mediterranean-style" pattern is one of the most consistently studied for lower inflammation and better joint comfort.

What to limit

  • Ultra-processed foods and added sugar — linked to higher inflammation.
  • Excess refined carbohydrates and fried foods.
  • Too much salt — can worsen fluid retention and swelling.

Reaching and keeping a healthy weight matters most of all for the knees: every extra kilogram multiplies the load on the joint with each step.

When diet needs a little help

Even a good diet can fall short of the concentrated collagen studied for cartilage. Mafsal Riyadi delivers high-tripeptide and type II collagen in one daily capsule — a licensed dietary supplement (EDA reg. no. 14711/2026) to complement healthy eating.
