Omega-3s are fatty acids that benefit your health in numerous ways. Since your body does not make them by itself, in order to function properly, you need to get them from foods and dietary supplements.
Did you know that most adults in the US don’t get enough Omega-3s in their diet? Omega-3 foods list can help fight depression, improve eye health and brain health, decrease risk factors of heart disease, and reduce symptoms of ADHD.
What Food Contains Omega 3 and What Types of Omega-3s Are There?
There are three types of omega-3 fatty acids: Docosahexaenoic acid (DHA), alpha-linolenic acid (ALA), and eicosapentaenoic acid (EPA).
- Docosahexaenoic acid is present in oily fish, such as mackerels, salmon, and sardines.
- Alpha-linolenic acid is found in seeds, nuts, and vegetable oils.
- Eicosapentaenoic acid is present in oily fish.

Do Eggs Have Omega-3 Fatty Acids?
If you’re not a big fan of seafood, then you can definitely include omega-3 enriched eggs in your diet. You’re probably wondering how omega-3 fatty acids get to eggs. Well, the answer is pretty easy. Eggs containing omega-3s are laid by hens which are fed on chia seeds, fish oil, and flax seeds. One egg contains approximately 100 to 500 milligrams of omega-3s.
Does Milk Contain Omega-3 Fatty Acids?
Milk is not believed to be a good source of omega-3s, although it can be fortified with these acids. In cows fed on vegetables that contain omega-3 fatty acids, or canola, or flax seed, there’s a maximized transfer of omega-3s from their diet to their milk. There is less than 1 gram of these acids in 244 grams of milk with 3.25 percent of fat. Additionally, conventional milk has a lower rate of omega-3s than organic milk, (organic milk refers to the milk produced by cows that are grass-fed).
Health Benefits of Omega-3 Fatty Acids
1.They Regulate Blood Sugar Levels
One study has revealed that omega-3 fatty acids have a protective effect on blood sugar levels. 148 Brazilian people with impaired glucose tolerance were included in the study and they were asked to consume Omega-3 foods with fatty acids over 12 months. After this period of time passed, 92 participants had normal levels of plasma glucose. It was also shown that some of the participants were more likely to enhance glucose disturbances (3).
2. Combined with Physical Exercise They Promote Weight Loss
One piece of medical research has proved this. 75 overweight or obese people were included in the research and they were assigned to two groups: Participants in the first group were asked to consume vegetable oil high in omega-6 fatty acids every day with or without doing exercises and participants in the other group were asked to take fish oil high in omega-3s with or without exercising for 12 weeks. The results showed that only the participants who took fish oil supplementation and exercised lost body fat (4).
3.They Reduce Inflammation
Omega-3 fatty acids may decrease the production of compounds that cause inflammation in the body. One study has reported that these acids have anti-inflammatory activities, and for this reason, they might be an effective tool for managing autoimmune and inflammatory conditions (5).
4. They Curb Your Appetite
One study which examined the impact of long chain omega-3s on appetite in obese and overweight people who are on calorie-restricted diet indicated that omega-3 fatty acids modulate satiety (6). So, if you want to feel full for longer, make sure you include omega-3 rich foods in your diet.
5. They Improve Your Cardiovascular Health
The DHA and EPA present in supplements and foods can reduce levels of triglycerides in the blood, thereby lowering the risk of developing heart diseases. However, these acids may slightly increase your bad cholesterol levels.
6. They Might Prevent Dementia and Alzheimer’s Disease
Some pieces of research indicate that people with increased omega-3s intake might be less likely to develop dementia or Alzheimer’s. However, more research is needed so as to better examine the impact of omega-3s on the brain.
7. They Have a Positive Effect during Pregnancy
Pregnant women should consume around 12 ounces of fish or other seafood a week as this may maintain the health of their baby. Nevertheless, they should eat fish that isn’t high in mercury, such as sardines, trout, herring, and salmon and they should eat two portions of fish a week at the maximum. They should also avoid consuming swordfish and shark. It’s worth mentioning that many formulas for feeding babies have DHA present in them.
8. They May Help Alleviate Symptoms of Rheumatoid Arthritis
Rheumatoid arthritis leads to stiffness and pain in the joints. Combining supplements that are rich in omega-3s with conventional medications for RA may help control this condition. For instance, for those suffering from RA, taking these supplements may cause them to lower the number of medicines they take to relieve their pain.
9. They May Prevent Age-Related Macular Degeneration
This is one of the conditions that lead to vision loss in older people. Increased intake of omega-3 fatty acids may decrease the risk of developing AMD. However, taking supplements containing omega-3s doesn’t prevent AMD from worsening when a person already has this condition.
Omega-3 Fatty Acids vs Omega-6 Fatty Acids
Omega-6 fatty acids are also obtained from food and as omega-3s, these acids play an essential role in our bodies too. However, there should be a balance between omega-3s and omega-6 fatty acids in the body as this is needed for the prevention of inflammatory processes. Namely, consuming large quantities of omega-6 fatty acids interferes with the anti-inflammatory properties of omega-3s.
Foods which are a rich source of omega-6 include: seeds, meat, safflower oil, avocado oil, tofu, corn, and nuts. So, to prevent inflammation in your body, make sure you consume less foods rich in omega-6 and consume more foods packed with omega-3s.
