Core Viewpoint - Thrombosis is a significant health risk, often referred to as a "silent killer," due to its high incidence, disability, and mortality rates. Preventive dietary measures can help reduce the risk of thrombosis. Dietary Recommendations - **Healthy Fats**: Incorporating oils rich in n-3 and n-9 fatty acids, such as perilla oil and olive oil, can lower cholesterol and triglyceride levels, aiding in thrombosis prevention. Recommended daily oil intake is 25-30 grams [1]. - **Fresh Fruits and Vegetables**: Consuming a variety of fresh produce, particularly dark-colored fruits and vegetables, can protect endothelial cells from oxidative stress and inflammation. The recommendation is to eat 5 fist-sized servings of vegetables and 2-3 fist-sized servings of fruits daily [3]. - **Fatty Fish**: Eating fatty fish like salmon and mackerel, which are high in DHA, can reduce platelet aggregation and protect vascular health. It is advised to consume fish at least twice a week, with each serving being about the size of a palm [5]. - **Foods Rich in β-Glucan**: Foods such as oats can help maintain normal cholesterol levels and reduce blood viscosity, thereby lowering the risk of thrombosis. Whole oats are preferred [7]. - **Soy Lecithin-Rich Foods**: Soy lecithin can help lower blood lipid levels and improve circulation. Daily intake of soy products should be around 15-25 grams, equivalent to approximately 350 grams of soy milk or 100-150 grams of tofu [8]. Foods to Limit - **Salt**: High salt intake can increase blood pressure, leading to vascular damage and higher thrombosis risk. The recommendation is to limit salt intake to no more than 5 grams per day [9]. - **Saturated Fatty Acids**: Foods high in saturated fats, such as fatty meats and butter, should be consumed sparingly as they can raise LDL cholesterol levels [10]. - **Trans Fatty Acids**: Foods that may contain trans fats, like certain baked goods, should be limited due to their adverse effects on cholesterol levels and increased heart disease risk [11]. - **High Cholesterol Foods**: Individuals with high cholesterol should avoid foods rich in cholesterol, opting for low-fat or fat-free dairy options instead [13]. Additional Recommendations - In addition to dietary changes, regular physical activity is essential. It is recommended to engage in aerobic exercise at least five times a week for over 30 minutes, along with resistance training two to three times a week [13].
