Evidence-based nutrition, in plain English — every entry sourced from clinical research.

Heart health is shaped by a long list of everyday choices — what you eat, how much you move, whether you smoke, and genetics you can’t control. Diet is one of the most consistently evidence-backed levers: certain foods, compounds and eating patterns are repeatedly linked to healthier cholesterol, blood pressure and inflammation markers across large studies. This hub gathers the foods, key compounds and lab markers most relevant to cardiovascular health from across the encyclopedia, along with any recipes built around them.

Common questions

What’s the single most important dietary change for heart health? There isn’t one silver bullet, but replacing saturated and trans fats with unsaturated fats (olive oil, nuts, oily fish) and increasing fibre intake are two of the most consistently supported changes across large studies and dietary guidelines.

Which lab markers matter most for heart health? LDL cholesterol, HDL cholesterol, triglycerides and blood pressure are the traditional core panel; ApoB and hs-CRP are increasingly used alongside them for a fuller picture of cardiovascular risk. See the biomarkers listed above for what each measures.
