High Omega 3 Foods (Per Serving)
If you find yourself falling short of the recommended omega-3 intake, it’s time to focus on foods that pack in more vitamin omega-3 per serving.
To help you get started, the infographic below shows the omega-3 provided by popular foods in the average serving sizes consumed by our Optimisers.
Once you’re ready to revitalise your diet with a wider variety of high-omega-3 foods, download our printable list of foods with more omega-3 per serving here.
It’s important to remember that animal foods are the only sources of both bioavailable omega-3 fatty acids—docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
While plant foods may contain some omega-3 fatty acids, most are in their inactive alpha-linolenic acid (ALA) form. Thus, they are not bioavailable. Those plant foods that do contain DHA and EPA—like marine algae—are inefficient, and we would have to consume large amounts of plant-based supplements to supply our needs.
Omega 3 Rich Foods (Per Calorie)
Once you know you’re getting the minimum amount of omega-3 your body needs, you can zero in on foods that deliver more omega-3 per calorie to increase your satiety and nutrient density. The infographic below shows popular foods that provide more omega-3 per calorie.

How Much Omega-3 Do You Need?
Our satiety analysis suggests that your body craves at least 2.1 mg of omega-3 per 2000 calories, which is slightly more than the Dietary Reference Intake of 1.6 g for men.
Achieving the Optimal Nutrient Intake of 5.6 g per 2000 calories from aligns with an 18% reduction in energy intake. However, the correlation between omega-3 and energy intake is quite weak as other nutrients play a larger role in our satiety response.
Omega 3 Rich Recipes
Elevate your culinary game with our chart, showcasing over 1400 NutriBooster recipes used in our Micros Masterclass. We’ve plotted these recipes based on omega-3 content versus protein percentage. The further right you go, the more omega-3 you can enjoy with fewer calories.
Omega-3s are one nutrient that doesn’t correlate with protein. Leaner fish and meat contain less fat and hence fewer omega-3s. So, once you ensure you’re getting adequate protein, it might be worth reviewing the omega-3 in your diet.

Benefits of Omega-3 Fatty Acids
- Heart Health: Omega-3s have been shown to reduce the risk of heart disease by decreasing blood pressure, lowering triglycerides, and preventing the formation of blood clots. They also serve as natural blood thinners.
- Brain Health: Omega-3 fatty acids play a crucial role in brain development and function, including supporting cognitive function and mental health. Studies have shown they can improve cognitive performance, memory, and mood.
- Immune System: Omega-3 fatty acids may support immune system function, potentially aiding in the body’s defence against common illnesses.
- Inflammation: Omega-3s have anti-inflammatory properties that help reduce inflammation in the body. Chronic inflammation has been linked to various health problems, including arthritis, cancer, and heart disease.
- Eye Health: Omega-3s are important for maintaining healthy vision and may help prevent age-related macular degeneration, a leading cause of blindness in older adults.
- Pregnancy and Infant Development: Omega-3s are essential in nutrition during pregnanacy for developing the brain and nervous system in infants and have been shown to reduce the risk of premature birth and low birth weight.
Roles of Omega-3 Fatty Acids in The Body
This family of essential fatty acids helps to:
- support heart health,
- manage pain,
- work as a natural blood thinner,
- support sperm health,
- reduce inflammation,
- support brain health,
- normalise cognition and memory,
- synthesise healthy cell membranes,
- improve liver health,
- regulate the immune response,
- improve the functioning of your nervous system,
- promote neurotransmitter balance,
- relieve depression, schizophrenia, ADHD, autism,
- improve sleep, and
- balance hormones.
Bioavailability of Omega-3s
The three most well-known omega-3 fatty acids are alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA).
ALA is the inactive form of omega-3s found in most plant oils, whereas DHA and EPA are the active forms of omega-3s. While they are predominantly found in animal foods, plant foods like marine algae contain relatively small amounts. Thus, you can get trace amounts from eating these foods or opt for supplements containing concentrated amounts of them; you’d just have to consume a substantial quantity of them to hit the RDA or (especially) the ONI.
The body can synthesise some EPA and DHA from ALA. However, the conversion is relatively inefficient, similar to beta carotene and retinol (vitamin A). Thus, consuming EPA and DHA from foods is extremely important. Essentially, the animal converts the plant O3s into bioavailable ones for us.
Omega-3s are nutrients that strict vegans and some vegetarians struggle to obtain in adequate quantities in their bioavailable forms because you must consume large amounts of expensive supplements regularly.
Interestingly, it seems women can convert more ALA to DHA and EPA for use in the body. Healthy men can convert 8% of ALA to EPA and 0-4% to DHA, while healthy women can convert up to 21% of ALA to EPA and 9% to DHA.
Given these low conversion rates from plant-based ALA to the bioavailable DHA and EPA, most people must find how to get DHA and EPA from fish-based sources to get enough bioavailable omega-3.
Symptoms of Omega-3 Deficiency
Symptoms of omega-3 fatty acid deficiency can mask themselves as commonplace signs and symptoms. You may need more omega-3s if you experience:
- dry skin,
- heart disease,
- age-related macular degeneration,
- cognitive problems,
- personality disorder,
- bipolar disorder,
- premenstrual cramps,
- autoimmune conditions,
- dry hair or dandruff,
- poor memory or learning difficulties,
- anxiety, or
- inflammatory health problems like arthritis, high blood cholesterol, depression, PMS, breast pain or water retention.
Although omega-3s are essential, we have a relatively weak satiety response to foods and meals that contain more of them, based on our satiety analysis.
People consuming more omega-3-rich foods tend to consume around 5% fewer calories than those who consume less foods high in omega-3s.
While omega-3s are essential and beneficial, it’s not just the omega-3s that provide the satiety benefit; it’s also the other nutrients—particularly protein—that tag along in most seafood.
The US Dietary Guidelines set a minimum intake of omega-3s at 1.1 grams per day for women and 1.6 grams per day for men. Meanwhile, the Australian guidelines are much lower and only recommend 0.16 g per day of omega-3 fatty acids. For reference, the average Optimiser intake is well above this at an impressive 3.1 grams of omega-3 fatty acids per 2000 calories.
While it is difficult to overdose on omega-3 fatty acids from food alone, some mild side effects can occur if someone supplements with too many omega-3s.
Although flaxseed oil is generally well-tolerated, high doses may cause diarrhea. In addition, allergic and anaphylactic reactions have been reported with flaxseed and flaxseed oil ingestion.
However, no severe adverse reactions have been reported in those using fish oil or other EPA and DHA supplements. It can cause a risk of nosebleeds and uncontrolled bleeding if consumed in high amounts because of its blood-thinning effects. A more common side effect of EPA and DHA supplements is a fishy aftertaste, depending on the product.
If you’re using a fish-derived omega-3 supplement, biting into a capsule or choosing the liquid may be a better option. If the oil tastes rancid or like it’s gone bad, this could indicate the oil has oxidised. Thus, it could be doing the opposite of what it’s intended to do!
Based on the robust satiety response data, we’ve set a stretch target of 6.0 milligrams per 2000 calories for omega-3s.
Once you start to get the hang of nutrient density, you could ‘level up’ by working to achieve these stretch targets to optimise your nutrition. For more details, see:
Rather than worrying about your omega-3 fatty acid intake, managing the ratio of omega-3 to omega-6 fatty acids may be more critical. Omega-3 and omega-6 fatty acids compete to use the same conversion enzymes, so consuming too much of one can deplete the other.

Omega 6 Fatty Acids
While you need some omega-6 fatty acids, excessive amounts can cause inflammation and outnumber the anti-inflammatory omega-3s in the body. A diet with excess omega-6 and little omega-3 is associated with increased inflammation. Conversely, a diet with a lot of omega-3s and sparse omega-6s has been shown to reduce inflammation.
The chart below shows that our intake of omega-6s like monounsaturated and polyunsaturated seed oils has been booming over the past hundred years! Unfortunately, most of these calories come from processed seed oils.
Before the advent of agriculture, we would likely have obtained more omega-3 fatty acids than omega-6s. While the overproduction of grains has allowed us to feed more people and cattle (to feed more people), we now have an influx of foods high in omega-6s, like seed oils, margarine, and animal foods that eat high omega-6 diets. Thus, the average omega-6:omega-3 ratio is between 12:1 to 25:1 today.
Even if you avoid bread and vegetable oils, the omega-6:omega-3 ratio in the food system is still high. Foods from animals fed on grains, including farmed fatty fish, contain elevated amounts of omega-6s, too.

Omega-3 fatty acids work synergistically with vitamins A, B3, B6, E, gamma-tocopherol, bioflavonoids, magnesium, methionine, quercetin, selenium, and zinc. For this reason, we recommend consuming nutrient-dense foods to get a complete spectrum of nutrients. This ensures that the body has the full array of vitamins and minerals that work in tandem to allow omega-3s to do their job.
Incorporating omega-3-rich foods into your diet is a step towards healthy eating and better nutrition.
