Cardiovascular health is not a mystery—it is measurable. The foods you choose directly affect four major risk factors: blood pressure, cholesterol, inflammation, and vascular function.
1. Blood Pressure Regulation
Sodium increases blood volume and arterial pressure, while potassium relaxes vessel walls and helps the body excrete excess sodium. When your diet includes fruits, vegetables, legumes, and low‑sodium choices, blood pressure stabilizes naturally.
2. Cholesterol Dynamics
LDL cholesterol becomes harmful when it oxidizes and infiltrates artery walls. Diets high in saturated fats, processed meats, and refined carbs accelerate this process.
Soluble fiber, healthy fats, antioxidants, and plant compounds do the opposite—they help clear LDL, raise HDL, and strengthen arterial resilience.
3. Inflammation and Oxidative Stress
A diet high in refined sugars, processed foods, and trans fats fuels chronic low‑grade inflammation.
A diet high in polyphenols (berries, herbs, olive oil), vegetables, nuts, and legumes lowers inflammatory markers and slows plaque formation.
4. Endothelial Health
Your endothelium—the inner lining of blood vessels—determines how well your arteries expand, contract, and communicate with your nervous system. Nitrate-rich vegetables (spinach, beets), omega‑3 fats, and antioxidant-rich foods protect this crucial tissue.
Your tasks for Lesson 2
- Track your sodium intake for one full day.
- Identify two simple swaps to reduce sodium (e.g., fresh herbs instead of packaged sauces).
- Add one potassium-rich food to your next meal.
