Methods of Consuming and Storing Flaxseeds


Hello, I would like to ask about the methods of consuming and storing flaxseed: since Brazil sells flaxseed powder, it is more convenient for us office workers.
However, I have heard that this may lead to a loss of its nutrients.
What should we do? Thank you!

Hello! Flaxseeds are rich in fats, primarily containing alpha-linolenic acid, which is an essential fatty acid for the human body.
Many nuts and plant oils also contain alpha-linolenic acid.
Flaxseeds should be stored like other high-fat foods, in a sealed, dry, and cool place, avoiding exposure to air and sunlight.
It is advisable to purchase them in small quantities to ensure they are consumed quickly.
Due to their high-fat content, it is important to monitor the total daily fat intake to prevent excessive fat and calorie consumption, which could pose health risks.
Wishing you health and happiness! Sincerely, Dietitian Shih Kuei-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

Flaxseeds, known for their rich nutritional profile, particularly in omega-3 fatty acids, fiber, and lignans, can be a valuable addition to your diet. However, how you use and store flaxseeds can significantly impact their nutritional benefits. Here’s a comprehensive guide on how to properly use and store flaxseeds for maximum nutrition.


1. Choosing the Right Form
Flaxseeds can be consumed in various forms: whole seeds, ground seeds (flaxseed meal), and flaxseed oil. Each form has its advantages:
- Whole Flaxseeds: While they have a longer shelf life, whole flaxseeds are not easily digested by the body. They can pass through the digestive system intact, meaning you may not absorb their nutrients effectively.


- Ground Flaxseeds: Grinding flaxseeds increases their bioavailability, allowing your body to absorb the omega-3 fatty acids and other nutrients more efficiently. Flaxseed meal can be added to smoothies, oatmeal, or baked goods.

- Flaxseed Oil: This is another option, but it lacks the fiber found in whole or ground seeds. Flaxseed oil is best used in salad dressings or drizzled over cooked vegetables, but it should not be heated, as high temperatures can degrade its beneficial properties.


2. How to Use Flaxseeds
- Incorporating into Meals: You can add ground flaxseeds to smoothies, yogurt, oatmeal, or baked goods like muffins and pancakes. A common recommendation is to consume about 1-2 tablespoons of ground flaxseeds per day.

- Hydration: When consuming flaxseeds, especially in ground form, it’s essential to drink plenty of water. Flaxseeds are high in soluble fiber, which can absorb water and expand in your digestive tract, aiding in digestion and promoting a feeling of fullness.


3. Storage Tips
- Keep it Cool: Flaxseeds, particularly ground flaxseeds and flaxseed oil, are sensitive to light, heat, and oxygen. Store whole flaxseeds in a cool, dark place, such as a pantry or cupboard. Ground flaxseeds should be stored in an airtight container in the refrigerator or freezer to prevent rancidity.

- Check for Freshness: If you’re using flaxseed oil, always check the expiration date and ensure it’s stored in a dark glass bottle. If the oil smells off or rancid, it’s best to discard it.

- Batch Preparation: If you buy flaxseeds in bulk, consider grinding only what you need for a week or two and storing the rest whole. This way, you preserve the nutrients and freshness of the seeds.


4. Potential Nutritional Loss
While it’s true that ground flaxseeds can lose some nutrients over time, proper storage can mitigate this. Ground flaxseeds can start to oxidize and lose their nutritional value within a few weeks if not stored correctly. Therefore, it’s advisable to grind flaxseeds in small batches and consume them relatively quickly.


5. Conclusion
In summary, to maximize the nutritional benefits of flaxseeds, opt for ground flaxseeds over whole seeds for better absorption, and store them in a cool, dark place to prevent nutrient loss. Incorporating flaxseeds into your diet can provide numerous health benefits, including improved heart health, digestive health, and potential anti-inflammatory effects. By following these guidelines, you can enjoy the full range of benefits that flaxseeds have to offer.
