Nutrition for Today: Wild-caught seafood not necessarily better than farm-raised

August 6, 2024 — There’s no question that fish and seafood are good for us.  Diets rich in seafood are consistently linked to lower risk of heart disease. For many years the American Heart Association has recommended that we eat at least two servings per week, and the Dietary Guidelines for Americans echo that same advice.

Seafood is rich in omega-3 fatty acids, which not only promote cardiovascular health, but help reduce inflammation in the body and help strengthen the immune system. Children born to mothers who consume seafood during their pregnancies have been shown to have better neurocognitive function.

The richest sources of omega-3s are fatty or oily fish, which include salmon, sardines, and mackerel. All fish contain these healthy fats, but the fattier fish contain more.

Marine Stewardship Council’s Advice for Heart Health Month

February 5, 2020 — The following was released by the Marine Stewardship Council:

The Marine Stewardship Council (MSC), a nonprofit with the sole mission to make sure the wild seafood you love is around forever, is encouraging consumers to eat more seafood during February Heart Health Month and all year long. The American Heart Association (AHA) recommends eating two, 3.5 ounce servings of seafood each week; however, USDA reports show a majority of Americans don’t meet the recommendation for fish and shellfish consumption.

The AHA and USDA recommendations are based on heart-health benefits shown from consuming one to two servings of omega-3 rich seafood per week, or about 250-500 mg of omega-3s a day, according to nonprofit organization and MSC partner Seafood Nutrition Partnership (SNP). One study[1] found that eating one to two servings of fatty fish a week reduces the risk of dying from heart disease by 36%.

“Fish and shellfish are very important parts of a heart-healthy diet,” said SNP’s Valerie Agyeman, a registered dietitian. “Seafood is a major source of healthy omega-3 fats and are also rich in nutrients such as vitamin D and selenium, high in protein, and low in saturated fat. There is strong evidence that eating fish or taking fish oil is good for the heart and blood vessels.”

According to a 2018 GlobeScan study commissioned by MSC, 70% of Americans believe supermarkets’ and brands’ claims about sustainability should be clearly labeled by an independent organization. As the first global science-based seafood certification program to be recognized for rigor and credibility by the United Nations, the MSC blue fish label is meeting increasing consumer demand for independent verification of sustainability claims by brands. The MSC works with the fishing industry, scientists, and conservation groups to create the world’s leading standard for sustainable seafood ensuring seafood is fished from stocks with healthy populations; caught with minimal impact on the marine environment; and in an area with effective, responsive, and responsible management.

“Eating seafood is integral to our heart health, and choosing sustainable seafood is integral to the ocean’s health,“ said Amy Gorin, MS, RDN, a registered dietitian in New York City. “For us, seafood provides essential nutrients – including omega-3 fatty acids needed for heart, brain and eye health. For the oceans, choosing sustainable seafood – such as wild-caught fish labeled with the MSC blue fish – means choosing seafood that’s good for you and for the oceans, too.”

Throughout Heart Health Month, the MSC will offer recipe inspiration on its blog and on social channels – @MSCBlueFish on Instagram, Twitter, and Facebook. Seafood dishes made with MSC certified fish are good for the entire family – from approachable, easy meals the entire family will love to sustainably-sourced pet food for your furry family members – continuing the conversation around seafood that’s good for you and good for the ocean.

“There are more than 3,000 products with the MSC blue fish label in U.S. stores,” said Brian Perkins, regional director for the Americas at the MSC Marine Stewardship Council. “Whether recipes call for frozen, canned or fresh fish, taking the simple step to look for the MSC blue fish label before you buy helps to protect oceans from overfishing, supports fishermen and fishing communities, and promotes traceability from ocean to dish.”

Studies: Omega-3s temper premature births, heart attacks

November 21, 2018 — New research linking omega-3 fatty acids with a reduced risk of cardiovascular diseases as well as the reduction of dangerous premature births is expected to have benefits for the seafood industry.

In a study of people who took Lovaza, a prescription omega-3 fish oil, researchers found that subjects were 28 percent less likely to suffer heart attacks than those taking a placebo. Additionally, people who ate fewer than 1.5 servings of fish weekly reduced their risk of cardiovascular disease by 19 percent when taking Lovaza.

The research was presented at the recent American Heart Association 2018 Scientific Sessions in Chicago, Illinois, and published in the New England Journal of Medicine.

“The use of fish oil did not significantly reduce risk for those eating more seafood, but the average overall showed a reduced risk,” Dr. Tom Brenna, a professor of pediatrics, chemistry, and nutrition at the University of Texas in Austin, Texas, and chair of Seafood Nutrition Partnership’s Scientific and Nutrition Advisory Council, told SeafoodSource. “The message here is, ‘If you don’t eat fish, take supplements.'”

Alongside the Lovaza study, a new Cochrane Review of 70 studies worldwide found that omega-3 fatty acids reduced dangerous preterm births by 42 percent.

The extensive review of published studies, which included 20,000 pregnant women, also revealed an 11 percent reduction in preterm births, and a 10 percent reduction in risk of having a low-birthweight baby. The researchers reviewed studies involving fish oil supplements as well as seafood.

“This study is further evidence that health professionals should be actively promoting fish and omega-3s among pregnant women as they have possibly the most to gain from eating more fish,” Jennifer McGuire, a registered dietitian for the National Fisheries Institute, told SeafoodSource.

Fish-oil drugs protect heart health, two studies say

November 12, 2018 — Two major studies released Saturday provide evidence that medications derived from fish oil are effective in protecting people from fatal heart attacks, strokes and other forms of cardiovascular disease.

The large, multiyear research efforts tested different formulations and quantities of drugs made with Omega-3 fatty acids on two groups of people: one that suffered from cardiovascular disease or diabetes and another that represented the general population. Both studies found that people who took the drugs every day enjoyed protection against some heart and circulatory problems compared with those given a placebo.

In a look at another commonly consumed supplement, vitamin D, researchers found no effect on heart disease but saw a link to a decline in cancer deaths over time.

The research was released Saturday at the American Heart Association’s 2018 Scientific Sessions in Chicago and published in the New England Journal of Medicine.

About 43 million people in the United States take statins to lower LDL, or “bad,” cholesterol, and the drugs are credited with reducing the risk of heart attacks and strokes. But heart disease remains the leading killer of Americans. In recent years, a long, steady decrease in heart disease deaths has slowed. So researchers are seeking other ways to combat cardiovascular disease beyond known protective factors such as changes in diet, exercise and smoking habits.

One of the studies unveiled Saturday, named by the acronym REDUCE-IT, determined that people with cardiovascular disease who were already taking statins stood less chance of serious heart issues when they were also given two grams of the drug Vascepa (icosapent ethyl) twice a day.

Fish Oil May Protect the Youngest Hearts

June 8, 2018 — Omega-3 fatty acids — good fats found in fish — can boost the heart health of adults, but a new study suggests that babies might also stand to benefit from them.

In the study from Australia, infants were given a daily fish oil supplement or a placebo from birth to 6 months. When they were 5 years old, researchers found that the children who had been given fish oil had smaller waists than the youngsters who were given a placebo. A larger waist circumference is a known risk factor for heart disease, according to the American Heart Association.

The researchers also found that boys given fish oil supplements in infancy had less circulating insulin in their bodies and less resistance to insulin when they were 5, though the study could only show an association between the two. Insulin is a hormone that carries sugars from the foods you eat into your cells to be used as fuel. Insulin resistance and higher levels of insulin play a role in the development of type 2 diabetes.

“It seems that using fish oil could help decrease waist circumference, which by itself, is a major cardiometabolic risk factor. But we can’t say for sure yet whether this will last,” said pediatric endocrinologist Dr. Siham Accacha. She was not involved in the study, but reviewed its findings.

“I’m also not sure why the insulin findings were only in boys. At age 5, there are no pubertal hormones, but obviously there was something there,” said Accacha, director of the pediatric diabetes program at NYU Winthrop Hospital in Mineola, N.Y.

What are the benefits of eating more fish?

August 14, 2017 — Jane DeWitt and Sabrina Lombardi are clinical nutrition coordinators of Food and Nutrition Services for Hackettstown Medical Center and Newton Medical Center at Atlantic Health System, respectively.

Q. What are the benefits of eating more fish?

A. Fish: Some people love eating it, and some people do not. But its health benefits are something that everyone can agree on.

“Studies show that increasing your fish intake is good for you, especially for your heart,” said Jane DeWitt, clinical nutrition coordinator of Food and Nutrition Services for Hackettstown Medical Center. “It’s leaner than red meat and some, like salmon, arctic char and sardines, are full of omega-3 fatty acids, which are great for your heart.”

Omega-3 fatty acids, which are essential fatty acids for human health, can help reduce inflammation as well as the risk for heart disease, notes DeWitt. The American Heart Association recommends up to two servings of fish per week, up to 8 ounces total. Omega 3 fatty acids are also beneficial for brain health as well help with memory, performance, and cognition.

Heart failure patients may benefit from fish oil

March 14, 2017 — A new American Heart Association report says people with heart failure may live longer by taking omega-3 fish oil supplements because they seem to reduce the heart disease death rate by almost 10 percent.

The association had previously concluded that such supplements may prevent death from heart disease in people who have already had a heart attack, but warned there is no solid evidence that fish oil can prevent heart disease in the first place, primarily because the issue hasn’t been studied.

“Reducing mortality by 10 percent would be important from a personal level and a population level,” coauthor Dr. David Siscovick said about the new advice for people with heart failure.

The scientific advisory published in the association’s journal Circulation updates a 2002 guidance with data from 15 newer studies. It comes at a time when about 19 million Americans – nearly 8 percent of the U.S. population – are already taking the supplements, many of whom may not be getting any real value from them.

Should you worry about mercury in seafood? What you need to know

December 15, 2016 — Are you feeling conflicted about eating seafood? Do you embrace the idea of getting healthy omega-3 fats in your diet — but worry that they might come with an unhealthy dose of mercury? If so, you’re far from alone — that’s one reason that the average American is not eating the recommended amount of fish and seafood.

The official recommendations for seafood consumption from the American Heart Association and the 2015-2020 Dietary Guidelines for Americans are to eat fish at least twice weekly — at least 8 ounces total — but only one in 10 of us do. The average person eats 3.5 ounces per week, and that drops to an average of 2 ounces during pregnancy — despite the recommendation that pregnant and breast-feeding women increase fish intake to up to 12 ounces per week.

If you’ve been playing it safe by limiting how much fish you eat, the good news is that you can relax. There’s a game-changer in the seafood and mercury debate — selenium. Selenium is an antioxidant mineral that helps prevent free radical damage to your cells, but it’s also an essential part of a few dozen enzymes (selenoenzymes) that protect your brain from damage. This is where seafood comes in.

According to Nicholas Ralston, Ph.D., a research scientist at the University of North Dakota’s Energy and Environment Research Center, part of the confusion about mercury and seafood comes from conflicting results from large studies on the effects of mercury consumption on childhood brain development. Ralston, who studies the health effects of mercury, spoke at the annual meeting of the Academy of Nutrition and Dietetics in Boston in October.

On one hand, two major studies, one from the Faeroe Islands and one from New Zealand, found low levels of harm from mercury exposure from seafood. On the other hand, studies in the United States and other countries found increased seafood consumption was associated with higher child IQ, despite mercury. Ralston said that when researchers dug harder to figure out what was driving the inconsistencies, they found the selenium link.

Mercury and selenium form an essentially unbreakable bond in your body. If you are getting more mercury than selenium, that doesn’t leave any “free” selenium for those brain enzymes. This can be especially devastating during pregnancy and shortly after birth, when a child’s brain is developing rapidly.

In the Faroe Island and New Zealand studies, the most heavily consumed types of seafood were whale and shark, which are high in mercury and very low in selenium. “That’s not what most people eat,” Ralston said. To top it off, both countries were also selenium-poor. “At the time of the study, New Zealand was one of the most selenium-poor nations on Earth. So throw some mercury at them, and they’re going to go down hard and fast.”

The U.S. is not a selenium-poor nation, but even if that weren’t true, the bottom line is that it is much safer to eat fish than to not eat fish. “There’s so much selenium in ocean fish that rather than falling behind in your selenium, you get enriched,” Ralston said. “The more fish you eat, rather than being in more danger of mercury toxicity, you’re safer.”
