How your diet affects cholesterol
Cholesterol is a type of fat your body needs in small amounts. The problem starts when you have too much of the wrong kind — LDL (low-density lipoprotein), often called “bad” cholesterol. High LDL levels can lead to plaque buildup in your arteries, raising your risk of heart disease and stroke.
Medication can help, but diet is one of the easiest ways to bring your cholesterol levels down. Some foods actively lower LDL, while others improve the balance between good (HDL) and bad cholesterol.
Best foods to lower cholesterol
High-fibre and plant-based options
Oats and barley — These whole grains are packed with soluble fibre, which binds to cholesterol in your digestive tract and helps flush it out. Just one bowl of porridge a day can make a noticeable difference.
Beans and lentils — High in soluble fibre and plant protein, legumes are excellent at reducing LDL levels. They also keep you full longer and support blood sugar control.
Berries — Blueberries, strawberries, and raspberries are loaded with antioxidants and fibre. They help reduce LDL oxidation — a key step in preventing plaque buildup.
Dark leafy greens — Spinach, kale, and collard greens contain compounds that help block cholesterol from being absorbed into the bloodstream. They're also packed with vitamins and minerals that support heart health.
Healthy fats for heart health
Avocados — Full of heart-healthy monounsaturated fats, avocados help raise HDL and lower LDL. Add a few slices to your salad or toast — it’s an easy win.
Fatty fish — Salmon, mackerel, sardines, and trout are rich in omega-3s. These healthy fats help lower triglycerides, support HDL, and reduce artery inflammation.
Olive oil — A staple of the Mediterranean diet, extra virgin olive oil is known to raise good cholesterol and lower the bad. Use it to cook or drizzle over vegetables and salads.
Nuts (especially almonds and walnuts) — Rich in healthy fats, magnesium, and fibre, nuts help lower cholesterol and reduce inflammation. A small handful a day is enough — no need to go overboard.
Soy products — Tofu, soy milk, and edamame contain compounds that block cholesterol absorption. Replacing animal protein with soy a few times a week can make a difference over time.
