1. Flaxseed Oil
Flaxseed oil is an excellent source of alpha-linolenic acid (ALA), a type of omega-3 fatty acid. Just one tablespoon provides a staggering 7.26 grams of ALA, which far exceeds the daily recommended intake. Whole flaxseeds are also beneficial, offering 2.35 grams of omega-3 per tablespoon. However, it’s important to note that flaxseed oil has a low smoke point. This means it can degrade and potentially release harmful substances when exposed to high temperatures, so it's best used in cold preparations or added to dishes after cooking.
2. Chia Seeds
Chia seeds are another stellar source of omega-3s, offering 2.53 grams per tablespoon. They are a particularly good option for those who may not enjoy the flavor of flaxseeds. In addition to their omega-3 content, chia seeds are also packed with fiber and protein, making them an excellent choice for those on plant-based diets.
3. Canola Oil
For those who need a high-temperature cooking option, canola oil is a great alternative. It boasts a high smoke point, making it suitable for frying, sautéing, and baking. Each tablespoon of canola oil contains 1.28 grams of ALA. It can effectively replace other cooking oils while helping you meet your omega-3 needs.
4. Walnuts
Walnuts are a tasty and nutrient-dense source of omega-3s. Eating about seven walnuts delivers up to 1.28 grams of ALA. Adding walnuts to your meals, such as in a chicken dish, can enhance the overall omega-3 content. While chicken breast contains minimal omega-3s (0.03 grams), it includes DHA and EPA, balancing your intake when combined with walnuts.
5. Soybeans
For vegans and vegetarians, soybeans and their products like tofu are excellent sources of omega-3s. A 100-gram serving of edamame (boiled and salted soybeans) provides 2.16 grams of omega-3s, making it a valuable addition to a plant-based diet.
6. Salmon
Salmon is renowned for its omega-3 content, specifically DHA and EPA. A serving of cooked salmon provides 1.24 grams of DHA and 0.59 grams of EPA. While fresh salmon typically does not contain ALA, canned salmon may offer up to 0.04 grams of ALA alongside its DHA and EPA. Other fatty fish, such as mackerel, trout, tuna, and sea bass, are also rich in omega-3 fatty acids.
7. Forage Fish
Forage fish like herring and sardines are excellent sources of EPA and DHA. A 3-ounce serving of herring contains 1.71 grams of omega-3s, while canned sardines offer about 1.19 grams. These smaller fish are not only rich in omega-3s but also often come with the added benefit of being less contaminated with toxins compared to larger fish.
8. Shellfish
Shellfish are unique in their omega-3 profile as they often contain all three types: ALA, DHA, and EPA. Oysters provide 0.67 grams of omega-3s per 3-ounce serving, lobsters offer 0.21 grams, and scallops have 0.15 grams. Incorporating these into your diet can diversify your omega-3 sources.
