Omega-3 foods: The best sources for a healthy diet

Omega-3 fatty acids are among the essential nutrients that our bodies cannot produce on their own. They are particularly important for heart health, brain function, and cell function. But which foods contain the most omega-3? In this article, you'll learn which omega-3-rich foods you should include in your diet to reap the numerous health benefits.

Why are omega-3 fatty acids so important?

Omega-3 fatty acids perform a variety of functions in the body. They support brain development and cognitive function, have anti-inflammatory effects, and play a crucial role in cardiovascular health. They also help regulate cholesterol levels and can reduce the risk of heart disease. Particularly important are the two long-chain omega-3 fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which are primarily found in marine sources. The plant-based omega-3 variant, ALA (alpha-linolenic acid), is found in certain nuts and seeds and can only be converted into EPA and DHA to a limited extent by the body.

The best animal sources of Omega-3

The best animal sources of omega-3 include fatty fish and seafood. Here are some of the best foods to include regularly in your diet:

Fatty fish as omega-3 bombs

Fatty fish are the best natural sources of EPA and DHA. Salmon is especially recommended, as it is one of the best sources of omega-3 fatty acids and contains high levels of EPA and DHA. Mackerel is also an excellent choice, as it is very rich in omega-3 fatty acids and is also an excellent source of vitamin D. Herring is also a fatty fish with high levels of omega-3 and B vitamins. Sardines, small but packed with omega-3 fatty acids, are a great alternative to larger fish. Tuna also contains valuable omega-3 fatty acids, but should be consumed in moderation due to potential heavy metal contamination.

Seafood and fish oil

In addition to oily fish, seafood also provides valuable omega-3 fatty acids. Krill oil and fish oil supplements are also a good way to meet your omega-3 needs. Algal oil is also a plant-based alternative for vegans, as it directly contains EPA and DHA. Those who don't want to or can't eat fish should consider algal oil as a dietary supplement to ensure an adequate supply of omega-3.

The best plant-based sources of omega-3

There are also many foods high in omega-3 for vegetarians and vegans, especially in the form of ALA:

Nuts and seeds

Flaxseeds are one of the best plant sources of omega-3. They contain particularly high levels of ALA and can be easily incorporated into smoothies or muesli. Chia seeds are also rich in omega-3 and fiber and promote healthy digestion. Walnuts are one of the best nut sources of omega-3 fatty acids and are an excellent addition to salads or snacks. Hemp seeds also contain valuable proteins and minerals in addition to omega-3.

High-quality vegetable oils

Flaxseed oil is the best plant-based source of ALA, but it shouldn't be heated, as high temperatures destroy the valuable fatty acids. Rapeseed oil offers a good balance between omega-3 and omega-6 and is ideal for cooking and frying. Walnut oil also contains a high amount of ALA and is great for salads or cold dishes.

Omega-3 ratio and the importance of Omega-6

In addition to the intake of omega-3 fatty acids, the ratio of omega-3 to omega-6 is also crucial for health. Omega-6 fatty acids are also essential, but an excess can promote inflammatory processes in the body. The optimal ratio of omega-6 to omega-3 is around 4:1 or lower. However, in modern diets, this ratio is often heavily skewed in favor of omega-6, which can increase the risk of chronic inflammation and related diseases. Consciously consuming omega-3-rich foods helps to correct this imbalance.

How much Omega-3 does the body need daily?

The recommended daily intake of omega-3 fatty acids varies depending on age and health. Experts recommend a daily intake of 250–500 mg of EPA and DHA for adults for optimal heart health. Pregnant and breastfeeding women have an increased need, as omega-3 is essential for the development of the baby. They should consume at least 300 mg of DHA daily. Vegetarians and vegans should increase their intake of ALA-rich foods or consider algal oil supplements, as the conversion rate of ALA to EPA and DHA in the body is relatively low.

Omega-3 supplements – useful or not?

Those who cannot meet their omega-3 needs through diet alone can turn to dietary supplements. High-quality fish oil capsules or algae oil supplements offer an easy way to obtain sufficient EPA and DHA. When purchasing, pay attention to high quality, purity, and sustainable production. Capsules with an optimal EPA to DHA ratio, such as those found in high-quality omega-3 products, ensure optimal absorption and bioavailability.

Conclusion: Omega-3 for a healthy diet

Omega-3 fatty acids are essential for numerous bodily functions and should be consumed daily through food. Fish lovers can easily meet their needs with salmon, mackerel, or sardines. Vegetarians and vegans can rely on flaxseed, chia seeds, or walnuts. If your diet isn't sufficient, high-quality omega-3 supplements can be a useful addition. Ensure a regular intake and a balanced ratio with omega-6 to benefit from the positive effects on your heart, brain, and inflammation.
