Wie Ihre Ernährung Ihr Herz beeinflusst

Herzkrankheit is one of the leading causes of illness and death worldwide, but many of the factors that increase your risk can be influenced by your lifestyle.

Diet plays an important role in keeping your heart and blood vessels healthy, affecting everything from Cholesterin and blood pressure to blood sugar levels and body weight.

No single food can prevent heart disease, but eating a balanced diet rich in nutritious foods can help lower your risk over time.

Why does diet matter for heart health?

The foods you eat provide the nutrients your heart needs to function properly. They also influence several risk factors for cardiovascular disease, including cholesterol levels, Blutdruck, blood sugar, and body weight.

A heart-healthy diet can help keep your blood vessels healthy, reduce strain on your heart and lower the risk of conditions such as Herzinfarkts und Schlaganfall.

Combined with regular exercise, not smoking and getting enough sleep, healthy eating is one of the most effective ways to protect your heart.

How diet affects cholesterol levels

Cholesterol is a fatty substance that your body needs to build cells and produce hormones. However, having too much low-density lipoprotein (LDL), often called "bad" cholesterol, can cause fatty deposits to build up inside your arteries. Over time, this can narrow the arteries and increase the risk of heart attack and stroke.

Diet can have a significant effect on cholesterol levels. Foods high in saturated fat, such as processed meats, butter, pastries and some full-fat dairy products, can raise LDL cholesterol in some people.

Replacing saturated fats with unsaturated fats found in foods such as olive oil, avocados, nuts, and seeds may help improve cholesterol levels. Eating plenty of fibre, particularly soluble fibre from oats, beans, lentils, and fruit, can also help lower LDL cholesterol.

How diet influences blood pressure

Blood pressure is the force of blood pushing against the walls of your arteries. High blood pressure makes your heart work harder and increases the chance of heart disease, stroke, and Nierenerkrankungen.

A diet high in salt can contribute to raised blood pressure, particularly in people who are sensitive to sodium. Most adults consume more salt than recommended, much of it from processed and packaged foods rather than the salt added during cooking.

Eating plenty of fruit and vegetables provides potassium, which helps balance the effects of sodium. Reducing highly processed foods and choosing fresh ingredients more often can also help support healthy blood pressure.

How blood sugar levels affect your heart

Persistently high blood sugar can damage blood vessels over time, increasing the risk of heart disease. This is particularly important for people with Diabetes oder Prädiabetes, who have a higher risk of developing cardiovascular disease.

Eating foods that provide steady energy, such as wholegrains, beans, pulses, and vegetables, can help avoid large spikes in blood sugar. Limiting sugary drinks and highly processed foods may also support healthy blood sugar control.

How weight and body fat affect heart health

Carrying excess body fat, particularly around your waist, is associated with an increased risk of heart disease. It can contribute to high blood pressure, raised cholesterol, insulin resistance, and Typ-2-Diabetes, all of which place extra strain on your heart.

Rather than focusing on restrictive diets or rapid weight loss, aim for sustainable eating habits that include a variety of nutrient-rich foods. Even modest weight loss can improve heart health in people who have overweight or obesity.

Can food cause inflammation in your body?

Inflammation is part of the body's natural defence system, but long-term, low-grade inflammation has been linked to the development of heart disease.

While no single food causes or cures inflammation, overall dietary patterns appear to influence inflammatory processes. Diets rich in vegetables, fruit, wholegrains, legumes, nuts, seeds, and oily fish are associated with lower levels of inflammation.

By contrast, diets high in processed foods, sugary drinks, and saturated fats may contribute to inflammation and poorer cardiovascular health.

Which diet is best for heart health?

There is no single "perfect" diet, but some eating patterns have consistently been linked with better heart health.

Mittelmeerdiät

Der Mittelmeerdiät is one of the most well-researched eating patterns for cardiovascular health. It emphasises vegetables, fruit, wholegrains, beans, lentils, nuts, seeds, olive oil, and fish, while limiting processed foods and red meat.

Research suggests that following a Mediterranean-style diet may help lower the risk of heart disease and stroke. It has also been linked with improvements in cholesterol levels, blood pressure, and blood sugar control.

DASH-Diät

Der Dietary Approaches to Stop Hypertension (DASH) diet was developed to help lower blood pressure but also benefits overall heart health.

It focuses on fruit, vegetables, wholegrains, low-fat dairy foods, lean protein, beans, and nuts while limiting foods high in salt, saturated fat, and added sugar. Studies have shown that the DASH diet can reduce blood pressure and may lower the risk of cardiovascular disease.
