Key Seafood & Omega-3 Research Findings
Learn about the large body of scientific evidence and seafood research that support eating seafood at least twice a week.
Dietary Guidelines recommend eating 6 oz. of seafood per week, 250 mg of omega-3 fatty acids EPA+DHA per day
USDA/HHS: The 2020-2025 DGA recommends a shift towards healthy eating patterns, which include a variety of protein foods including more seafood. The general population should eat at least 6 ounces of seafood per week with the aim to take in at least 250 mg per day of omega-3 fatty acids EPA and DHA, and women who are pregnant or breastfeeding should eat at least 6 ounces of seafood per week for omega-3 fatty acid DHA to improve infant health outcomes.
The Ultimate Guide to Making Smart Seafood Choices
Eat seafood with confidence. The real risk is not eating enough!
Here are a few facts about seafood requirements versus mercury risks, what science shows about safe limits, what fish and shellfish you should choose, and what to avoid too much of.
Live (Healthier) Longer
Fish literally saves lives. Eating seafood two to three times per week reduces the risk of death from any health-related cause by 17 percent.
Seven out of 10 deaths in the U.S. are preventable through nutrition and lifestyle changes, like adding omega-3s to your diet. Low seafood intake contributes to 55,000 deaths each year, making seafood deficiency a leading dietary contributor to preventable death in the U.S.
Fish Consumption for Pregnant Women
Neonatology Today: Pregnant women today are mindful of the importance of prenatal care and prevention, particularly with respect to nutrition. The National Coalition for Infant Health, together with Neonatology Today, released seafood advice for mothers and their babies.
Eat Seafood While Pregnant: All Benefits, No Harm Says Renown Harvard Professor
American Journal of Clinical Nutrition: Dr. Emily Oken of Harvard Medical School concludes the science on benefits and lack of harm from prenatal fish consumption is settled for now, that seafood consumption by pregnant women is in fact beneficial for baby brain development and shows no harm.
Japan Environment and Children’s Study found “maternal fish intake during pregnancy was independently associated with reduced risk of delay in problem-solving at age 6 [months] and in fine motor skills and problem-solving at age 1 [year].” The study also found, as summarized by Oken, “None of the results suggested harm from higher fish consumption.”
Scientific Review Shows Children Can Gain an Average of 7.7 IQ Points
PLEFA: A paper published by a group of 13 leading dietary fats scientists highlights the tremendous health benefits from consuming seafood for infant and adolescent brain development. Among the key findings of the systematic review is an average 7.7 IQ point gain in children whose mothers ate seafood during pregnancy compared to mothers who did not eat seafood.
FAO/WHO: A joint FAO/WHO Expert Consultation on the risks and benefits of fish consumption concluded that the benefits of eating fish outweigh the risks. Babies from moms who ate seafood twice a week were observed to have a greater IQ by 5.8 points. The study shows benefits for improved IQ and heart health.
Omega-3 fatty acid DHA supports better outcome for baby brain and eye health
AND: The Omega-3 fatty acid docosahexaenoic acid (DHA) is critical for the development of the nervous system, especially during the first year of life according to a study in the Journal of the Academy of Nutrition & Dietetics.
National Institute on Aging
A recent study led by Dr. Christopher Ramsden published in the British Medical Journal found that people who followed a diet high in the omega-3 fats found in fish and shellfish, and low in omega-6 fats found in many processed foods, showed a decreased frequency and severity of headaches. Participants ate foods including wild salmon, albacore tuna, and trout while minimizing sources of omega-6 fats such as corn, soybean, and canola oils.
Recently approved migraine medications have been shown to produce two to two and a half fewer “headache days” per month, which is less than the four-day reduction caused by the high omega-3, low omega-6 diet. “Four days per month really outperform anything we’ve seen from a pharmacological preventive,” said Dr. Rebecca Burch, a headache medicine specialist at Brigham and Women’s Hospital and an assistant professor of neurology at Harvard Medical School.

“As calcium is to the bones, DHA is to the brain,” says Dr. Tom Brenna, member of the 2015-2020 Dietary Guidelines Advisory Committee. Seafood provides docosahexaenoic acid (DHA), a type of omega-3 essential for brain development and function, helping neurons trigger and cells regenerate.
It is important to remember that our daily food choices influence our mental health as much as other self care such as physical activity, connecting with friends and family, and sleep. And the evidence is strong that seafood is brain food.
People who regularly eat fish are 20% less likely than their peers to have depression. Eating 2-3 servings of seafood a week significantly reduces the risk for major depression, which is why the American Psychiatric Association endorse the omega-3 fatty acids in fish as an effective part of depression treatment.
People who eat fish frequently have 14% larger brain hippocampus – the big memory and learning center
UCLA: A study in the American Journal of Preventive Medicine led by Dr. Cyrus Raji found that people who regularly eat fish have more voluminous brains than those who do not. This study found that eating fish—baked or broiled, never fried—is associated with larger gray matter volumes in brain areas responsible for memory and cognition in healthy elderly people.
“If you have a stronger hippocampus, your risk of Alzheimer’s is going to go down,” said Dr. Raji.

Regular fish eaters less likely to suffer from depression
People who regularly eat fish are 20 percent less likely than their peers to have depression. In fact, the American Psychiatric Association has endorsed the fatty acids in fish as an effective part of depression treatment.
Older adults with highest blood levels of omega-3 fatty acids lived on average 2.2 years longer
HARVARD: A study from Harvard School of Public Health and the University of Washington found that older adults who had the highest blood levels of the omega-3 fatty acids found in fish lived, on average, 2.2 years longer than those with lower levels.
Breaking News from American Heart Association: “Keep saying yes to fish twice a week for heart health”
AHA: A scientific advisory released May 2018 from the American Heart Association reaffirms the Association’s recommendation to eat two servings of fish per week: Seafood Long-Chain n-3 Polyunsaturated Fatty Acids and Cardiovascular Disease: A Science Advisory From the American Heart Association. This Advisory summarizes evidence to support the beneficial effects of long-chain polyunsaturated fatty acids (LC n-3 PUFAs) from seafood on cardiovascular disease and stroke. This summary is consistent with the AHA 2020 impact goals to include seafood as part of the healthy dietary pattern goals and the 2015 AHA Diet and Lifestyle Recommendations.
Study shows eating seafood 2x week reduces the risk of dying from heart disease by 36%
HARVARD: Drs. Mozaffarian & Rimm found that eating approximately one to two 3 oz. servings of fatty fish a week—salmon, herring, mackerel, anchovies, or sardines—reduces the risk of dying from heart disease by 36 percent. Heart disease is the #1 killer of Americans taking almost 600,000 lives each year per the CDC.
Higher blood levels of omega–3 fatty acids had a risk reduction of sudden cardiac death of 80-90%
NEJM: In the Physicians’ Health Study, 22,071 male physicians were followed over 17 years, found that those with the highest blood level of long-chain omega-3 fatty acids compared to those with the lowest blood level had an 80-90% risk reduction in sudden cardiac death per New England Journal of Medicine.
Study shows Mediterranean diet health benefits reduce risk of heart disease by 30%
NEJM: A Mediterranean diet that includes seafood at least twice a week reduced the incidence of major cardiovascular events according to the New England Journal of Medicine.
Heart disease is 80-90% preventable with proper diet, exercise, and lifestyle modifications
AHA: Coronary heart disease is 90% preventable with proper diet and exercise per American Heart Association.
WHO: Up to 80% of cases of coronary heart disease, 90% of type 2 diabetes cases, and one-third of cancers can be avoided by changing to a healthier diet, increasing physical activity, and stopping smoking per World Health Organization.
