Edible fat has a bad reputation: it is suspected of making you fat, clogging blood vessels and causing life-threatening cardiovascular diseases. But not all fats are harmful, some are even vital.

Unsaturated fatty acids: olive oil, rapeseed oil, fish

Humans do not produce healthy unsaturated fatty acids themselves, but take them in through food.

  • Monounsaturated fat helps the body utilize fat-soluble vitamins. It's found in foods like olive oil, avocados, nuts, and margarine. The fat in olive oil has a particularly favorable composition: Current studies show that it can even lower the risk of cardiovascular diseases. Two to three tablespoons of olive oil per day are recommended.
  • Polyunsaturated fat is an important part of the cell walls. It is involved in controlling blood pressure, balancing cholesterol levels and regulating inflammation. The ratio of omega-3 and omega-6 fatty acids is particularly important: while omega-3 fatty acids tend to have anti-inflammatory effects, degradation products of omega-6 fatty acids tend to promote inflammation. To increase the amount of omega-3 fatty acids in the diet, it makes sense to cook with rapeseed oil and occasionally eat high-fat fish such as salmon, mackerel or herring. Omega-6 fatty acids, on the other hand, should be consumed in moderation, for example in sunflower oil.

Saturated fat: butter, milk, cheese

The large amounts of unhealthy saturated fatty acids enhance the taste of food and thereby increase appetite. They cause the bad LDL cholesterol to rise in the blood - it can promote the development of cardiovascular diseases, vascular calcification, dementia and diabetes. Saturated fat is mainly found in animal products such as butter, lard, cream, sausage, cheese and meat. The nervous system needs saturated fat as a messenger substance. So in moderation, butter, whole milk, and high-fat cheese are good for the body.

Trans fats: candy, chips, fast food

Trans fats are unhealthy. They arise when unsaturated fat is strongly heated or industrially hardened. Trans fat is found in convenience foods, chips, and candy. It has an unfavorable effect on the blood lipid metabolism and can promote cardiovascular diseases.

Cholesterol: Diet and Medicines

New research shows that people react differently to a high-fat diet. The level of cholesterol is therefore primarily a question of genes. Diet can increase or decrease the natural cholesterol level by around 15 percent. If you have too much bad cholesterol in your blood, you can only partially change this through an adapted diet, but in many cases are dependent on cholesterol-lowering medication.
