Canned Sardines, Mackerel and Anchovies: the Best Natural Sources of Omega-3

Canned sardines, canned mackerel and canned anchovies are among the best natural sources of omega-3 fatty acids. In addition to providing EPA and DHA, these oily fish naturally contain protein, iodine, selenium, vitamin D and vitamin B12.

Convenient, affordable and easy to store, they make it simple to include oily fish regularly in a varied and balanced diet. Moreover, their long shelf life makes them a practical option for everyday meals.

Why Choose Canned Oily Fish?

Canned sardines, mackerel and anchovies offer several advantages. On the one hand, they naturally retain their nutritional value. On the other hand, they are ready to eat and can be stored for a long time.

  • Rich in EPA and DHA omega-3 fatty acids
  • Source of complete protein
  • Naturally contains iodine and selenium
  • Long shelf life
  • Easy to use in everyday meals

Canned Sardines: Omega-3, Protein and Calcium

Canned sardines are naturally rich in valuable nutrients. They provide EPA and DHA omega-3 fatty acids, high-quality protein and calcium when the bones are consumed.

In addition, sardines are small fish that live low in the food chain. As a result, they generally contain fewer contaminants than large predatory fish.

Canned Mackerel: A Leading Source of Omega-3

Canned mackerel is one of the fish naturally richest in omega-3 fatty acids. Therefore, it is an excellent choice for increasing omega-3 intake throughout the year.

Furthermore, mackerel naturally provides protein, selenium, iodine and vitamin D.

Canned Anchovies: Small Fish, Great Nutrition

Canned anchovies are best known for their intense flavour. However, they also provide omega-3 fatty acids, protein, phosphorus, iodine and selenium.

Thanks to their distinctive taste, they easily enhance salads, pasta dishes and Mediterranean recipes.

Iodine, Selenium and Protein: Essential Nutrients

Iodine contributes to normal cognitive function and normal thyroid function. Meanwhile, selenium contributes to the protection of cells from oxidative stress and supports the normal function of the immune system.

In addition, protein contributes to the maintenance of muscle mass and normal bones.

What Do Scientific Studies Say About Omega-3?

According to the European Food Safety Authority (EFSA), EPA and DHA contribute to the normal function of the heart. To benefit from this authorised health claim, a daily intake of 250 mg of EPA and DHA is recommended.

Best sunscreen 2026

Choosing a good SPF50 sunscreen is not only about the level of protection. Texture, formulation, water resistance and comfort during application also play an important role. Today, organic sunscreens mainly rely on two approaches: mineral filters and modern organic filters. Both can provide effective UVA and UVB protection when properly formulated and correctly applied.

☀️ Why choose an SPF50 sunscreen?

An SPF50 sunscreen is especially recommended during prolonged sun exposure, at the beach, in the mountains or during outdoor sports activities. It is also suitable for sensitive, fair or reactive skin. However, even high protection requires generous and regular application to remain effective.

🌿 Organic sunscreens with mineral filters

Mineral filters, mainly zinc oxide and titanium dioxide, work on the skin surface by absorbing, scattering and reflecting part of the UV rays. They are widely used in organic sunscreens because of their good tolerance and UV stability. The certified organic sun care products from La Canopée perfectly illustrate this new generation of sun protection that combines effectiveness, high tolerance and pleasant application. Their fluid and comfortable textures provide a more pleasant sensory experience while ensuring effective UVA and UVB protection.

Advantages of mineral filters:

  • Good tolerance for sensitive skin
  • Immediate protection after application
  • Good stability under sunlight
  • More natural approach and often certified organic

Things to know:

  • Some formulas may leave a slight white cast
  • Application must be even to ensure optimal protection
  • Sprays and powders are not recommended due to inhalation risks

💧 A new generation of more comfortable organic sunscreens

Some recent sun protection products aim to combine the advantages of mineral filters with a more comfortable everyday texture. This is particularly the case with the Fluide Solaire Lacté SPF50 Bio Corps & Visage, which offers high protection with a more discreet finish on the skin compared to traditional mineral sunscreens.

Its fluid texture also provides good hydration and water resistance, making it suitable for both daily use and outdoor activities. As with all sunscreens, it remains essential to reapply regularly, especially after swimming, sweating or towel drying.

⚗️ Modern organic filters

Modern organic filters absorb UV rays and convert this energy into heat. They generally allow very fluid, invisible and comfortable textures that are especially appreciated for sports or frequent applications.

Advantages:

  • Light and invisible texture
  • Easy and even application
  • Excellent daily comfort
  • Good resistance during outdoor activities

Things to know:

  • Less associated with a natural image
  • Quality strongly depends on the overall formulation

⚖️ How to choose the right sunscreen?

  • Sensitive skin and daily use: mineral filters
  • Sports, beach and heavy perspiration: fluid and water-resistant textures
  • Looking for natural products: organic mineral sunscreen
  • Comfort and invisibility: next-generation formulations

📌 Tips for effective sun protection

  • Apply before sun exposure
  • Use a sufficient amount on all exposed areas
  • Reapply every two hours
  • Reapply after swimming or sweating
  • Avoid prolonged exposure during the hottest hours

A good organic SPF50 sunscreen is above all a protection adapted to your skin, your lifestyle and pleasant enough to be applied correctly and regularly.

Hexane: a controversial solvent for extracting vegetable oils

Hexane is a petrochemical solvent that has been used since the 1940s to extract oil from oilseeds (rapeseed, sunflower, soya…). This method is very cost-efficient and achieves a yield of up to 99%, making it the most widely used industrial technique for producing refined oils.

⚠️ Why is hexane a problem?

Neurotoxicity: Hexane is classified as neurotoxic, with potential risks to the nervous, reproductive and endocrine systems. Public health issues relate primarily to chronic exposure.

Possible residues in food: Analyses have identified traces of hexane in some refined oils as well as in by-products (milk, butter, meat) derived from animals fed with hexane-extracted oilcake.

Loss of nutritional value: Chemical extraction and subsequent refining affects the flavour and reduces the content of sensitive nutrients in vegetable oils.

Environmental impact: Hexane is highly volatile and contributes to air pollution and poses a risk to workers exposed in the extraction plants.

🫒 How can you avoid hexane in your food?

  • Choose virgin oils, extra virgin oils or oils from first cold pressing: they are extracted mechanically without chemical solvents.
  • Favour organic oils, where the use of hexane is strictly prohibited.
  • Avoid ” refined “, ” neutral ” or ” deodorised ” oils: they often come from chemical extraction.

🌿 In conclusion

Hexane offers a very high yield for the industry, but its use raises major challenges: public health, nutritional quality, transparency and environmental impact. To consume in a healthier and more sustainable way, opt for organic, virgin and cold-pressed oils.

☕ Carasso: Freshly Roasted Organic Coffee – No Compromise on Quality

At 7-bio.ch, we’ve chosen exceptional organic coffee – but above all, freshly roasted coffee. That’s why we offer Carasso coffees, roasted in Geneva using traditional methods, only on demand. The result? A coffee that’s nothing like what’s been sitting on supermarket shelves for weeks.

🔥 Roasted to order, never stored

We don’t keep Carasso coffees in stock. Each customer order is passed directly to the roaster. Once the beans are freshly roasted and packed, we collect them and ship them without delay. This ensures you receive coffee at its peak freshness.

👃 Maximum aroma, unmatched flavour

Freshly roasted coffee reveals its full aromatic potential: floral, fruity, toasted… The essential oils are still intact, the flavours are clear, balanced, and never overly bitter. What you’re drinking is a living coffee, not an oxidized one.

🌿 Organic and healthy: no pesticides, fewer risks

Carasso coffee is organically grown and reduces exposure to mycotoxins like ochratoxin A. These invisible mould toxins develop in poorly stored or old beans. Thanks to careful selection and fast packing after roasting, this risk is greatly reduced.

💡 Why it matters

  • ✅ Superior taste experience
  • ✅ Better for your health (fewer toxins)
  • ✅ Supporting local craftsmanship (Carasso has roasted in Geneva since 1866)
  • ✅ Less waste – roasted only when needed, no overstock

Taste the difference.
With freshly roasted Carasso coffee, every cup becomes an experience. Order now at 7-bio.ch and bring meaning back to your coffee ritual.

Which oils are best for healthy cooking? The 7-bio guide

Not all oils are created equal in cooking. Some can withstand high heat very well, while others must remain raw to preserve their benefits. At 7-bio.ch, we offer you a selection of high-quality organic oils tailored to your needs: gentle cooking, high-temperature cooking, or seasoning.

🧪 Good to know:

A study published in March 2025 in the journal Science revealed that linoleic acid — an omega-6 fatty acid found in large quantities in conventional sunflower, soybean, and corn oils — may promote the growth of aggressive cancer cells via the FABP5 protein. This highlights the importance of choosing oils rich in oleic acid (omega‑9), such as high oleic sunflower oil, which are more stable when heated and potentially safer for long-term health.

1. High-Temperature Cooking (180–240°C)

Ideal for pan-frying, oven cooking, grilling, or deep-frying:

  • Avocado oil – Very high smoke point (~270°C), neutral taste, rich in healthy fats (oleic acid).
  • Virgin coconut oil – Excellent cooking stability, with a light and pleasant aroma.
  • Ghee (clarified butter) – Lactose-free alternative to butter, suitable for high-heat applications.
  • High oleic sunflower oil – Rich in omega‑9 (oleic acid), more stable and healthier than standard sunflower oil, ideal for high-heat cooking.

2. Gentle Cooking (up to 160–180°C)

Perfect for stews, slow-cooked meals, or steaming:

  • Extra virgin olive oil – Rich in antioxidants and oleic acid, stable at moderate heat.
  • Sesame oil – Best for Asian dishes or light stir-fries.
  • Virgin rapeseed (canola) oil – A good source of omega‑3, suitable for gentle cooking.

3. Oils to Be Consumed Exclusively Raw

Use these oils for seasoning, salad dressings, or drizzling over steamed vegetables:

  • Flaxseed oil – Exceptionally rich in omega‑3, delicate and should be kept refrigerated.
  • Walnut oil – Elegant nutty flavor, ideal in green salads or over fresh cheeses.
  • Hemp oil – Offers a well-balanced omega‑3 to omega‑6 ratio.

4. Summary Table

For a quick overview:

Oil Max Temperature Best Use
Avocado 270°C Deep-frying, oven, wok
Coconut 230°C Pan-frying, sweet & savory dishes
Ghee 250°C Grilling, high-heat cooking
High oleic sunflower oil 220–230°C Frying, sautéing, oven cooking
Olive 180°C Gentle cooking
Sesame 170°C Asian dishes
Rapeseed 150°C Steaming, low-heat dishes
Flax / Walnut / Hemp <130°C Raw use, seasoning

Conclusion

At 7-bio.ch, we’ve curated a range of organic oils — many cold-pressed — that suit your culinary needs. Choosing the right oil protects both the flavor of your food and your long-term well-being. For high-heat applications, high oleic sunflower oil is a smart and healthy choice over standard sunflower oil.
