The Benefits of Fish Oil for Diabetes Management
For those living with diabetes, controlling blood sugar levels is crucial but can also be challenging at times. Making smart dietary choices is key, and fish oil is one supplement that research shows can have beneficial effects on insulin sensitivity and inflammation.
Fish oil contains the omega-3 fatty acids EPA and DHA which have powerful anti-inflammatory properties in the body. Reducing chronic inflammation helps improve the body's ability to regulate blood glucose levels over time.
How Fish Oil Helps People With Diabetes
Taking fish oil supplements may:
- Increase insulin sensitivity
- Protect cells in the pancreas that produce insulin
- Lower triglycerides
- Reduce atherosclerosis risk
- Improve arterial health and blood flow
For those reasons, the American Diabetes Association recommends people with diabetes boost their omega-3 intake by eating fatty fish at least twice a week or taking fish oil supplements.
Best Types of Fish Oil Supplements
The highest quality fish oil supplements will contain higher amounts of beneficial EPA and DHA omega-3s. Look for brands validated by third party testing organizations like the GOED standard for purity and correct dosages.
Pharmaceutical grade fish oils go through additional filtration processing to remove toxins like mercury leading to the purest supplements. But they come at a higher price point.
Correctly Storing Fish Oil Supplements
Like other polyunsaturated fats, fish oil is prone to oxidation which causes it to go rancid over time. That’s why proper storage guidelines are important for retaining potency and nutritional value once a bottle is opened.
Should You Refrigerate or Freeze Fish Oil?
Freezing is the most optimal storage method for maintaining supplement freshness. Manufacturers often recommend refrigeration instead since not everyone has access to a freezer. But research shows colder freezer temps better protect delicate fish oil integrity.
One study tested fish oil capsules under four conditions for 6 months - room temp, refrigerator, freezer, and repeated freeze/thaw cycles. Freezer storage with no temperature fluctuations proved best at preventing omega-3 breakdown over time.
Tips for Freezing Fish Oil Pills
Follow these best practices for freezing fish oil supplements:
- Seal original container: Keep capsules inside the dark, oxygen limiting bottle they came in for freezing.
- Exclude air: Fill extra space in bottle with cotton balls to reduce air exposure.
- Use freezer bags: Place sealed supplement bottle inside ziplock freezer bag to prevent frost damage and light exposure.
- Freeze immediately: Freeze unopened bottle promptly after purchasing for maximum stability.
- Avoid thawing: Prevent freeze/thaw cycles by only removing what you'll use short term. Leave bulk supply frozen.
How Long Does Frozen Fish Oil Last?
Most fish oil capsules maintain quality and potency for:
- 18-24 months when stored continuously frozen
- 6-8 months refrigerated after opening
- 3-6 months at room temperature once opened
Discard any bottles past expiration date or if odor, appearance or texture changes as that may indicate oxidative rancidity.
Tips for Taking Fish Oil Supplements With Diabetes Medications
Combining fish oil with common medications used to regulate blood sugar levels is generally considered safe. But there are some important interactions and timing considerations for optimal dietary supplementation:
Metformin
Fish oil may boost the glucose lowering effects of metformin. Monitor blood sugar closely when initially adding fish oils in case metformin dosage needs adjustment.
Sulfonylureas
Like glimepiride, glyburide or glipizide, sulfonylurea drugs stimulate the pancreas to release more insulin. Fish oil can also increase insulin production leading to possible hypoglycemia if sulfonylurea dosage is too high.
Insulin
Because fish oil may enhance insulin sensitivity, speak with your doctor about monitoring blood glucose levels more frequently after starting supplements to assess if insulin dosages need tweaking.
Timing with Medications
Take fish oil supplements with food rather than on an empty stomach which can cause indigestion, fishy burps or stomach upset for some. Avoid taking fish oils at the exact same time as other meds - separate dosages by at least an hour or two.
Getting Enough Omega-3s in Your Diet With Diabetes
Beyond taking supplements, getting more omega-3 rich foods in your daily nutrition plan can promote heart and blood sugar health. The American Heart Association recommends all adults eat fatty fish at least twice weekly as part of a balanced, diabetes friendly diet.
Best Fish Choices High in Omega-3s
Excellent fish picks providing over 500mg omega-3s per 3 ounce cooked serving include:
- Salmon
- Sardines
- Oysters
- Trout
- Atlantic mackerel
- Tuna
- Herring
For canned tuna or salmon options choose water packed varieties over oil to avoid excess calories and sodium.
Fish Oil Omega-3 Content by Type
Fish oil supplements contain concentrated amounts of beneficial EPA and DHA fats. Just one 1,000mg fish oil capsule typically provides around:
- 300mg DHA
- 200mg EPA
Whereas obtaining an equivalent 500mg dose from salmon alone would mean eating over 5 ounces!
Vegetarian Omega-3 Options
For vegetarians and vegans who avoid fish, algal oil supplements provide comparable DHA/EPA amounts. Certain seeds and nuts like flax, chia and walnuts also contain the plant based omega-3 called ALA thought to have anti-inflammatory effects as well.
Simple, Diabetic Friendly Recipes With Fish
Incorporating more omega 3-rich fish like salmon or tuna into your meal plan is easy with simple recipes like:
Lemon Thyme Baked Salmon
A bright lemony herb crust keeps wild caught salmon moist and flavorful for a easy weeknight sheet pan dinner. Pair with roasted asparagus or broccoli.
Tuna Salad Stuffed Avocado
Flaky albacore tuna salad made with nonfat greek yogurt and celery gets stuffed into avocado halves for a nutritious lunch full of heart healthy fats, protein and fiber to help stabilize blood sugar.
Southwestern Tuna Cakes
Pan seared blackened tuna patties come together quickly with beans, corn, peppers, cilantro and seasoning for a spice packed spin on crab cakes. Enjoy in lettuce cups with salsa and guacamole.
Experiment with adding more omega-3 boosting fish into diabetic meal plans for better blood sugar control and heart protective effects.
FAQs
Is it safe to take fish oil if I have diabetes?
Yes, fish oil is considered safe as part of a balanced diet and may provide positive benefits like improved insulin sensitivity and lower inflammation for many people with diabetes.
Why does fish oil need to be frozen?
Freezing prevents oxidation and rancidity better than storage methods at higher temperatures. Keeping fish oil capsules frozen retains supplement potency and nutritional quality for longer duration.
Can I freeze opened fish oil pills?
Yes, freeze opened bottles promptly after taking out intended short term supply. Exclude air exposure in the container and use freezer bags for dark, steady temperature. Just avoid frequent freeze/thaw cycles.
Is it okay to take fish oil with diabetes medications?
Fish oils are typically safe with metformin, sulfonylureas and insulin but may enhance effects. Monitor blood sugar closely when first adding supplements in case medication adjustment is necessary over time.
