Myth 1: Eggs are bad for your cholesterol 

The truth:
For most people, eggs can be part of a healthy diet. Eggs contain cholesterol, but the saturated fat in foods like processed meats, pastries and takeaways have a much bigger impact on blood cholesterol levels.

Myth 2: Butter is healthier than spreads because it is “natural” 

The truth: Butter is high in saturated fat, which can raise cholesterol levels. Vegetable-based spreads usually contain higher amounts of mono and poly unsaturated fats, which are better for your heart and cholesterol.  

Small amounts of butter are okay – remember it is your diet as a whole that has the biggest impact on your overall heart health. If you choose to use butter, choose the unsalted version and use sparingly.

Myth 3: If I take cholesterol tablets, I can eat whatever I want 

The truth:
Cholesterol-lowering medicines can help, but healthy eating still matters. Food choices, physical activity and medication work best when all used together. 

Medicines help, but a healthy lifestyle is still important. This is not just for your cholesterol, it will also help with blood pressure, weight management and reduce the risk of developing other conditions like type 2 diabetes.

Myth 4: All processed foods are bad for you 

The truth: 
Not all processed foods are unhealthy. Foods like porridge oats, wholemeal bread, milk, tinned beans and frozen vegetables are processed but can be nutritious. The foods to limit are those that are highly processed and high in salt, sugar or saturated fat. This includes foods like crisps, sweets, sugary drinks and processed meats such as  sausages and bacon. 

Myth 5: I need to cut out all fats to protect my heart

Myth 6: Dairy foods are bad for your heart

The truth: 
Dairy foods such as milk, yoghurt and cheese can be part of a heart-healthy diet. They provide important nutrients including protein, calcium and iodine. Current heart health guidance does not recommend avoiding dairy altogether. Instead, if you have high cholesterol, it may help to choose lower-fat dairy products more often, as some dairy foods can be high in saturated fat. Your diet as a whole is more important than any single food.
