Which foods or supplements keep your blood vessels healthy?
The Mediterranean diet most demonstrably lowers your risk of heart and blood vessel disease. Individual supplements do not help.
The Mediterranean diet has the strongest support. Studies in people show that it improves your blood fats, inflammation markers and waist size. You have fewer heart attacks and die less early. That protection works partly through your gut bacteria and less chronic inflammation, even without dramatic weight loss or a drop in cholesterol. A diet focused mainly on blood pressure features in all major guidelines.
Eating plant-based with plenty of unprocessed vegetables, fruit and wholegrains consistently lowers your risk. Going fully vegan offers no proven extra benefit over a vegetarian or Mediterranean pattern. What matters is the quality and degree of processing of your food, not simply cutting out animal products.
Ultra-processed products, lots of red meat, salt, sugar and saturated fat raise your risk instead. Potassium from your plate, think vegetables, pulses and fruit, is linked to a lower risk. That does not automatically apply to potassium supplements.
Individual vitamins or minerals, including calcium and selenium, offer no proven protection for your heart and blood vessels. Focus on your overall eating pattern, not on individual pills.
Less saturated fat and more fibre lower your LDL, the harmful blood fat that speeds up the hardening of arteries. The earlier you reach healthy levels, the greater the benefit over your entire lifetime. For ketogenic eating and intermittent fasting, short-term results are sometimes promising, but there are too few long-term data on actual heart and blood vessel disease. If you already have risk factors and find it hard to make changes, structured behavioural support can help.
Based on many studies combined and studies in people. The Mediterranean diet has the strongest foundation in studies in people; other patterns rely partly on people followed for years and guideline assessments.
How healthy are my blood vessels / what is my vascular age?
For a first impression of your vascular health, an ApoB blood test is the simplest and most accessible step; a CAC scan adds the most value when your risk remains unclear after blood testing.
Are calcium supplements bad for your heart?
Calcium supplements may be associated with an increased heart risk, but not all studies confirm this. It is best to get calcium from your diet, and discuss with your doctor whether a supplement is truly necessary for you.
Can clogged blood vessels be cleaned up again?
Early arterial hardening can partly be reversed, especially with strong LDL reduction using statins or newer medicines. The earlier you act, the more you can expect to gain, so discuss your cholesterol and blood pressure levels with your doctor.
What does my blood pressure tell me about my long-term health?
Your blood pressure and how much it fluctuates between measurements clearly say something about your risk of heart and vascular disease and dying in the long term. For those who are eligible for treatment, medication is the most evidence-backed step.
What is a healthy HDL (good cholesterol) level, and can I raise it?
Raising HDL through lifestyle is possible, but your genes set the ceiling. Lowering triglycerides through less sugar and alcohol, more exercise, and weight reduction has the greatest effect.
Do omega-3 (fish oil) supplements benefit my heart?
Fish oil reliably lowers triglycerides and can slightly reduce the risk of a heart attack in people with existing heart disease or high risk, but it does not demonstrably lower the overall risk of death. Always discuss its use with your doctor if you have a condition or are on medication.
