Heart Health
Cardiovascular health is best supported by whole dietary patterns, not single superfoods.
Key compounds
The evidence base for this goal focuses on several well-studied compounds.
- Lycopene — Lycopene is the carotenoid behind the deep red of a ripe tomato, and one of the most efficient antioxidants in the plant kingdom. Unusually, it becomes
- Omega-3 — Omega-3s are a family of essential polyunsaturated fats the body cannot make in meaningful amounts, so they must come from the plate. The two with the
- Potassium — Potassium is the body’s principal intracellular electrolyte, quietly partnering with sodium to manage fluid balance, nerve signals and every heartbeat. Most of us fall short of

Source: USDA FoodData Central (FDC 171705, Avocados raw all commercial varieties) — corrected 2026-07-01, prior fibre (0g) and saturated fat (11.6g, ~57% of total fat) were stale/inconsistent with any USDA source; the previously-linked Foundation record (2710824) does not report fibre, sugar or saturated fat at all, so those 3 fields were carrying leftover values from before this food was USDA-enriched. Switched to the complete SR Legacy record for full internal consistency.

Practical takeaways
Focus on consistency, variety and the overall dietary pattern. Smaller daily choices tend to outperform occasional large changes.
Common questions
Is one compound enough? Rarely. Whole foods and dietary patterns usually outperform single-compound strategies.
How fast can diet change inflammation or blood markers? It depends on the marker, the starting diet and lifestyle factors. Expect gradual trends rather than overnight shifts.
