Summary
A study from Australia's Edith Cowan University found that higher dietary intake of vitamin K1 — found in leafy green vegetables like spinach, kale, and broccoli — was associated with a 16% lower likelihood of developing chronic obstructive pulmonary disease (COPD) over a ten-year period. The research distinguishes between vitamin K1 (from vegetables, involved in blood clotting) and vitamin K2 (from fermented foods and animal products, important for bone health), and suggests leafy greens may offer protective benefits for lung health.
