What are saturated and trans fats?Show answer
Diets high in saturated fat (fatty meats, butter, many processed foods) and trans fats tend to raise LDL cholesterol, promoting plaque build-up. Trans fats are particularly harmful.
What is salt?Show answer
A high salt intake raises blood pressure, which damages artery walls and strains the heart, increasing CVD risk.
What is excess energy?Show answer
Diets high in energy from fat and sugar promote overweight and obesity, which are linked to high blood pressure, unhealthy blood lipids and type 2 diabetes, all of which raise CVD risk.
What are unsaturated fats?Show answer
Replacing some saturated fat with unsaturated fats from oils, nuts and oily fish helps improve blood lipids. Oily fish supplies omega-3 fatty acids linked to heart health.
What is dietary fibre?Show answer
Soluble fibre from oats, legumes, fruit and vegetables can help lower LDL cholesterol.
What are fruit, vegetables and wholegrains?Show answer
These supply fibre, potassium and protective compounds, and support a healthy weight and blood pressure.
