Health organizations recommend a minimum of 250–500 mg of omega-3 fatty acids per day for healthy adults. Fatty fish, algae, and several high-fat plant foods contain high amounts of omega 3.
1. Cod liver oil: It is an oil extracted from the livers of codfish. This is high in omega-3 fatty acids and also contains vitamins D and vitamin A. So, you get 3 nutrients in one.
Omega-3 content: 2,682 mg per tablespoon.
2. Flax seeds: These are small brown or yellow seeds that are often ground, milled, or used to make oil. These are the richest whole-food source of omega-3 fat alpha-linolenic acid (ALA). Therefore, flaxseed oil is often used as an omega-3 supplement.
Omega-3 content: 2,350 mg per tablespoon (10.3 grams) of whole seeds and around 7,260 mg per tablespoon (13.6 grams) of oil.
3. Chia seeds: Chia seeds are rich in manganese, selenium, and magnesium. A standard 1-ounce (28-gram) serving of chia seeds contains 5 grams of protein and all eight essential amino acids.
Omega-3 content: 5,060 mg per 28 grams.
4. Walnuts: They contain high amounts of copper, manganese, and vitamin E and are loaded with fiber.
Omega-3 content: 2,570 mg per 28 grams.
5. Soybeans: Soybeans are a good source of fiber and vegetable protein and also contain other nutrients, including riboflavin, vitamin K, folate, magnesium, and potassium.
Omega-3 content: 1,443 mg per 100 grams.
6. Mackerel: Mackerel are small, fatty fish. They are incredibly rich in nutrients. 100-gram serving packs about 200% of the Reference Daily Intake (RDI) for vitamin B12 and 100% for selenium.
Omega-3 content: 5,134 mg per 100 grams.
7. Salmon: It is a fish that contains high-quality protein and a variety of nutrients, including large amounts of vitamin D, vitamins B, and selenium.
Having this fish in your diet lowers the risk of diseases like heart disease, dementia, and depression.
Omega-3 content: 2,260 mg in 100 grams.
8. Sardines: Sardines are very small, oily fish. They’re highly nutritious when eaten whole as they contain almost every nutrient your body needs.
Omega-3 content: 1,480 mg per 100 grams.
9. Anchovies: Anchovies are tiny, oily fish often bought dried.
Anchovies are a source of niacin and selenium, and boned anchovies also contain calcium.
Omega-3 content: 2,113 mg per 100 grams.
DOSAGE: WHO recommends a daily intake of 0.2–0.5 grams (200–500 mg) of EPA and DHA together.
Consider a fish oil supplement that provides at least 0.3 grams (300 mg) of EPA and DHA per serving.
