Why they are essential for your health
Fats often have a bad reputation, but they are essential for many physical functions - especially for the health of your nerves. Especially in winter, when our bodies have to contend with less sunlight and colder temperatures, our nerves need special nutrients to function optimally. Certain fats play a key role in this: They protect the nerve pathways, support signal transmission and can reduce inflammation. In addition, they have a positive effect on your cognitive abilities, mood and concentration. This article shows you which sources of fat are particularly healthy, which fats you should avoid and how you can effectively integrate them into your everyday life. Studies, figures and practical tips give you a well-founded overview.
Fats and their importance for nerve health
The human nervous system consists of a complex network of cells that depends on an adequate supply of fats. Around 60% of the brain is made up of fat, and the myelin sheath that surrounds the nerve fibers consists mainly of fatty acids. Without this sheath, nerve impulses would be transmitted more slowly or not at all.
1. Protection of the nerve pathways
Omega-3 fatty acids, such as those found in oily fish or flaxseed, help form and repair the myelin sheath. This fatty layer acts as an insulator and protects the nerves from damage. Studies show that high levels of omega-3 can reduce the risk of neurological diseases by up to 40%. For example, a study by Harvard Medical School showed that regular consumption of omega-3-rich foods significantly improves brain health. Omega-3 also helps reduce oxidative stress, which damages nerve cells. A deficiency in these fatty acids is associated with a 60% higher risk of depression, according to the WHO.
2. Signal transmission in the nervous system
Certain fats play a central role in communication between nerve cells. Phospholipids in particular, such as those found in egg yolks or soybeans, support the formation of neurotransmitters such as serotonin and dopamine. These neurotransmitters are crucial for memory, concentration and emotional stability. A study by UCLA shows that people who regularly consume avocados achieve 15% better cognitive performance. The study included 200 participants over a period of six months and showed that daily consumption of avocados significantly improved both memory performance and problem-solving ability.
3. Anti-inflammatory
Chronic inflammation can have a lasting impact on nerve health. Healthy fats such as the omega-9 fatty acids found in walnuts or avocados have an anti-inflammatory effect and reduce the risk of nerve inflammation by up to 25%. In addition, these fats improve blood flow to the nerves and help keep the blood vessels elastic.
Comparison of healthy fat sources and their effects
| fat source | active ingredients | effect on nerve health |
|---|---|---|
| fatty fish | omega-3 fatty acids | Building and protecting the myelin sheath, reducing inflammation |
| flax seeds and chia seeds | alpha-linolenic acid (ALA) | Improve nerve communication, anti-inflammatory |
| walnuts | Omega-3 and polyphenols | Protection against oxidative stress, strengthening of nerve cell membranes |
| avocado | Omega-9 fatty acids, vitamin E | Anti-inflammatory, improves cognitive functions |
| olive oil (extra virgin) | polyphenols and healthy fats | reduction of inflammation, cell regeneration |
| egg yolk | phospholipids | Promotes the formation of neurotransmitters, improves memory performance |
| soybeans | lecithin | Supports nerve function and ability to concentrate |
Which fats you should avoid
Not all fats are good for your nerves. Trans fats and too many saturated fatty acids can affect nerve health. They promote inflammation, inhibit blood circulation and can disrupt the function of nerve cells in the long term.
| Unhealthy source of fat | Contents | Negative effects |
| Fried foods | trans fats | Promote inflammation, increase the risk of neurodegenerative diseases |
| margarine | Industrial trans fats | Inhibits myelin formation, negative for nerve communication |
| meat products | Saturated fatty acids | Increase inflammation levels, strain the cardiovascular system |
| cookies and baked goods | Hidden trans fats | Promote oxidative stress, impair cognitive functions |
| Vegetable oils with omega-6 excess | linoleic acid | Can promote inflammation if consumed in excess |
Trans fats should be avoided as much as possible because they promote the formation of harmful inflammatory substances. Typical foods with a high trans fat content include fried foods such as chips, industrially produced biscuits or croissants, and some margarines. These products should be replaced by healthier alternatives wherever possible. Average consumption in industrialized countries is 1.3% of energy intake, although experts recommend keeping this value below 1%.
Tips for integrating healthy fats into your daily routine
-
Breakfast: Add ground flaxseeds or chia seeds to your yogurt to give your day an extra dose of omega-3.
-
Lunch: Prepare a fresh salad with avocado and walnuts and use extra virgin olive oil as a dressing.
-
Snacks: Swap chips for a handful of walnuts or almonds.
-
Dinner: Include fatty fish such as salmon or mackerel in your diet at least twice a week.
-
Cooking: Use olive oil instead of butter or animal fats.
Even small adjustments to your diet can have a big impact on your nerve health.
Recipe recommendations for the integration of healthy fats
These simple and delicious recipes show you how you can easily incorporate healthy fats into your diet. Feel free to adapt the ingredients to the current season to always use fresh and local food. In spring, for example, you can use fresh spinach or wild garlic, while in autumn pumpkin or beetroot are a wonderful addition:
1. Omega-3 breakfast bowl
Mix 200g of yogurt or a plant-based alternative such as coconut or almond yogurt with 1 tablespoon of ground flax seeds, 1 tablespoon of chia seeds and a handful of blueberries. Top with chopped walnuts and a teaspoon of honey for a perfect start to the day.
2. Avocado-Walnut Salad
Prepare a fresh salad with rocket, spinach, half an avocado and 30 g chopped walnuts. You can also refine the salad with pomegranate seeds or dried cranberries to give it a fruity note. Alternatively, other leaf salads such as lamb's lettuce or baby spinach can also be combined excellently. Refine it with a dressing made from extra virgin olive oil, lemon juice and a pinch of salt.
3. Salmon fillet on a bed of vegetables
Place a fresh salmon fillet on a bed of zucchini, peppers and tomatoes. Alternatively, use tofu or tempeh to create an equally nutrient-rich and plant-based version of this dish. Drizzle with olive oil and season with herbs such as rosemary and thyme. Bake in the oven at 180°C for around 20 minutes - a delicious omega-3 meal that is perfect to complement with a side dish such as quinoa or brown rice to create a complete meal.
Conclusion
Healthy fats are essential for a high-performance nervous system. They protect the nerve pathways, promote signal transmission and reduce inflammation. At the same time, you should avoid unhealthy fats as they can damage the nerves. By integrating high-quality sources of fat such as fish, walnuts or olive oil into your everyday life, you can improve your cognitive functions and strengthen your nerves in the long term. Rely on healthy fats - for your health and well-being!
