Why is fat important to humans
Why fats are important to the body
At least since the low carb boom that has continued to this day, many nutrition-conscious people have agreed that fat is important for the body. But what is fat actually good for in the body? Which fats are healthy? How much fat does the body need? We clarify these questions in the current blog post.
Whether in fish, oil or meat - fatty acids are a natural component in our food. These can be roughly divided into saturated, monounsaturated and polyunsaturated fatty acids. The human body cannot produce the latter itself. For this reason, polyunsaturated fatty acids are also known as essential fatty acids. Nutritionists differentiate between omega-3 and omega-6 fatty acids. In order for the body to function properly, these fatty acids must be ingested through food.
Why does the body need fat?
Fat is an essential part of the body. Above all, the body needs essential fatty acids to build cell membranes such as muscles, nerve cells or the retina. Multi-saturated fatty acids also affect blood clotting, cholesterol levels and inflammatory processes.
Long-chain forms of omega-3 fatty acids, which the body can use directly, are particularly important. According to studies, the majority of the population is insufficiently supplied with omega-3 fatty acids. In contrast, many people are oversupplied with linoleic acid, one of the omega-6 fatty acids. Animal products such as meat or sausage, for example, are rich in linoleic acid.
Omega-3 vs. Omega-6 fatty acids
Due to current eating habits in the western industrialized countries, the recommended ratio between the fatty acids is often strongly shifted to the disadvantage of the omega-3 fatty acids. Too much omega-6 fatty acids can even be harmful to the body and promote inflammation. Omega-3 fatty acids, in turn, have an anti-inflammatory effect, experts agree. Omega-3 fatty acids, on the other hand, have an anti-inflammatory effect and help to dissolve existing sources of inflammation in the body, but the intake of omega-6 fatty acids is extremely important. Because without this, inflammation cannot develop and thus give the body the opportunity to “report” in the event of an illness if something is not right. This signaling effect is therefore vital.
According to the World Health Organization (WHO), a favorable ratio of omega-6 and omega-3 fatty acids is important to keep the body in balance. A 5: 1 ratio of omega-6 to omega-3 fatty acids is recommended.
Which fats are healthy?
Sea fish (e.g. salmon, mackerel, tuna or herring), vegetable oils (e.g. Osolio fit 4 life, rapeseed oil or linseed oil), avocados, walnuts, almonds or chia seeds are good sources of fat of long-chain omega-3 fatty acids.
If these fats are consumed in moderation and combined with other important foods (water, fiber, proteins and vitamins), nothing stands in the way of a healthy lifestyle.
