1. Leafy Greens
Leafy greens such as spinach, kale, and Swiss chard are exceptional sources of vitamin K, folate, and a variety of antioxidants that contribute to vascular health. Vitamin K plays a crucial role in blood clotting regulation, which is directly relevant to reducing stroke risk. Folate supports homocysteine metabolism; elevated homocysteine levels are linked to increased stroke risk, so maintaining adequate folate intake helps mitigate this.
Incorporating leafy greens into your diet can help manage blood pressure by promoting better endothelial function and reducing arterial stiffness. Practical ways to add these greens include blending them into smoothies, tossing them into salads, or lightly sautéing as a side dish.
2. Fatty Fish
Fatty fish such as salmon, mackerel, and sardines are rich in omega-3 polyunsaturated fatty acids (EPA and DHA). These fats have anti-inflammatory properties, reduce blood triglyceride levels, and improve endothelial function, all of which contribute to lowering the risk of ischaemic stroke caused by blood clot formation.
Omega-3s also have mild blood-thinning effects, which can help prevent thrombosis. Consuming fatty fish at least twice per week is recommended to achieve these benefits. For those who do not eat fish, omega-3 supplements may be considered but should be discussed with a healthcare provider, especially if blood-thinning medications are used.
