Heart disease remains the leading cause of death worldwide. The good news: diet is one of the most powerful modifiable risk factors. Foods rich in potassium, fiber, and antioxidants — and low in sodium and saturated fat — can meaningfully reduce your risk.
What this guide optimizes for
Foods are ranked for this specific goal, not for generic “healthiness.” That keeps the list more useful in practice.
How the numbers work
All data comes from USDA FoodData Central and is standardized per 100g so foods can be compared on equal footing.
How to use it
Use the top few foods as anchors, then mix in the rest for variety, cost, and easier meal planning.
How to apply this goal guide
Goal guides are meant to help you build a pattern, not obsess over a single perfect food. The best choices here are foods that repeatedly support the outcome you care about.
Use first
Pick 2 or 3 high-ranking foods you will actually buy every week.
Then balance
Layer in cheaper, easier, or more enjoyable foods from lower down the list to stay consistent.
Watch tradeoffs
Strong foods for one goal can still be salty, fatty, or calorie-dense, so the caution notes matter.
