Tips on Selecting and Storing Flaxseed
For optimal nutrition and shelf life, consider these pointers:
- Choose Ground Flaxseed: Whole flaxseeds are hard to digest, limiting nutrient absorption. Opt for ground flaxseed (flaxseed meal) or grind whole seeds just before eating.
- Look for Freshness: Purchase flaxseed from trusted sources with proper packaging.
- Store Properly: Keep flaxseed in a cool, dark place. Refrigerate ground flaxseed in an airtight container to preserve freshness and prevent rancidity.
Important Considerations and Possible Interactions
- Allergens: Flaxseed allergies are rare but possible. Introduce flaxseed gradually if you haven’t tried it before.
- Digestive Sensitivity: High fiber content may cause bloating or gas if introduced suddenly; start with small amounts and increase slowly.
- Medication Interactions: Flaxseed may interfere with certain medications, particularly those affecting blood clotting (anticoagulants); consult your healthcare provider if unsure.
- Hydration: Drink plenty of water to aid digestion when increasing fiber intake.
Frequently Asked Questions About Flaxseed Nutrition
- Is it better to buy whole or ground flaxseed?
Ground flaxseed is best for digestibility and nutrient absorption. Whole seeds may pass through the digestive tract intact. - How much flaxseed should I eat each day?
A common serving is 1-2 tablespoons per day. Introduce slowly and listen to your body. - Does heat destroy flaxseed’s nutrients?
Some nutrients, like ALA, can degrade slightly with excessive heat, but most can withstand baking temperatures. For maximum benefit, add flaxseed to foods after cooking when possible. - Can flaxseed help with weight management?
Flaxseed is filling due to its fiber, which may help control appetite when included in a balanced diet.
