Gout: Another Area for Omega-3 Fatty Acids?

April 21, 2016 — A group of researchers recently proposed a novel approach to gout management in the April 2016 issue of Annals of the Rheumatic Diseases. They hypothesized that omega-3 fatty acids may prevent acute gout attacks through their anti-inflammatory effects.

The study assessed 112 men, and the researchers established 2 arms:

  • 31 patients in the case arm had had 2 or more gout attacks in the past year
  • 81 patients in the control arm had fewer than 2 gout attacks

The researchers assessed baseline characteristics in all patients and compared age, body mass index, tophi, serum uric acid, treatment, and disease duration with patients’ serum omega-3 fatty acid levels.

Participants who reported more than 2 acute gout attacks in the past year had lower omega-3 fatty acid levels. This suggests that omega-3 fatty acid supplementation could potentially help decrease the risk of gout attacks.

Is Fish Oil Beneficial for the Brain?

April 19, 2016 — One element that distinguishes humans from other primates is the high levels of omega-3 fatty acids within the brain. These long chain polyunsaturated fats play an important role in the cell membranes of neurons and other cells of the body, increasing permeability and controlling some signaling between cells. Deficiencies in omega-3 in both animals and humans has been shown to be correlated with increased mental health problems and even a higher risk of suicide.

Over the years, a lot of research has been done with omega-3s to see if supplements could help with various psychiatric problems from depression to autism to dementia. Anyone following news coverage will see headlines going from boom to bust for omega-3s, “no help” says one study, “strong benefit for depression” says another. How do we make sense of it all?

First a little overview. Omega-3 fatty acids for supplementation come in three major varieties, ALA, EPA, and DHA. It’s a bit of an alphabet soup, but bear with me. ALA is the precursor molecule that can be converted to EPA and DHA in the body, but the rate of conversion is never higher than 20% or so. That means if you take a lot of ALA (found in flax or chia seeds), you end up with a lot of excess omega-3 in your body that may not be particularly useful to the brain. All polyunsaturated fatty acids are delicate, easily made rancid with exposure to oxygen, so having extra omega-3s the body can’t use well may not be the best idea. EPA and DHA, on the other hand, are the fatty acids found in fish oil, and DHA is the major long chain omega-3 fatty acid in the human brain. There is an algae-made vegan DHA supplement that is added to milk and formula that you might have seen in the grocery store.

Shift to plant-based fish feed could hurt health, environment

March 25, 2016 — In an effort to make fish farming more sustainable, the aquaculture industry has been cutting back on feed made of other fish and replacing it with plant-based alternatives. But a new study warns that may make the fish less healthy to eat and have negative impacts on the environment.

Many fish species that are farmed, including Atlantic salmon, the most farmed fish in Canada, are carnivores that eat feed traditionally based on fish meal and fish oil. Environmental advocates such as Greenpeace have criticized the practice as unsustainable, as wild fish that could be used to feed people or maintain wild populations need to be caught in order to produce the fish food.

“They realized that we’re grinding up a lot of fish to feed the fish,” said Jillian Fry, director of the Public Health and Sustainable Aquaculture Project at Johns Hopkins University in Baltimore, Md.

The price of fish meal and fish oil has also increased with demand.

Omega-3 concerns

The study said the use of plant-based ingredients could reduce the amount of healthy omega-3 fatty acids in fish – one of the things that makes fish like salmon attractive and tasty to consumers.

While this is something salmon farmers are aware of and trying to avoid, Fry says, omnivorous fish that already eat more plant material and have less omega-3s, such as tilapia, may end up with even lower levels.

“Anywhere it’s decreasing in our diet, we need to pay attention.”

Higher blood levels of omega-3 may help depression in heart patients

March 17, 2016 — Despite earlier reports to the contrary, patients suffering from heart disease and depression may benefit from taking supplements of omega-3 fatty acids.

New research at Washington University School of Medicine in St. Louis indicates that initial levels of omega-3 fatty acids in a heart patient’s blood have a significant impact on whether that person will respond to omega-3 supplements to treat depression.

“We found that people with higher levels of omega-3 in their blood may benefit more from additional omega-3, in the form of supplements, than those whose blood levels of the fatty acids were lower at the outset,” said principal investigator Robert M. Carney, professor of psychiatry. “Because depression is linked to heart attacks and sudden cardiac death in patients with cardiovascular disease, we have been trying to figure out how best to improve depression in these patients. These findings offer potential answers for a very significant problem.”

The findings are published in The Journal of Clinical Psychiatry.

Farm-Raised Seafoods Fed Plant-Based Diet Have Lower Levels of Omega-3 Fatty Acids

March 14, 2016 — A change in how farmers are raising seafood is expected to affect human nutrition, a new study found.

According to the research team from the Johns Hopkins Center for a Livable Future (CLF) at the Johns Hopkins Bloomberg School of Public Health, the University of Minnesota’s Institute on the Environment and McGill University, there has been a global shift in the type of feed that is being used in fish farming.

The team explained that prior to this shift, farm-raised seafood ate feed made from fish meal and fish oil, which came from wild fish. However, since catching wild fish to use as feed was no longer sustainable, farmers have been relying on plant-based options, such as soybean meal. The researchers noted in 2008, aquaculture feed contained 50 percent more soybean meal than fish meal. They estimated that from 2008 to 2020, the use of plant-based ingredients can increase by 124 percent.

‘Supplements and Safety’ Explores What’s in Your Supplements

January 19, 2016 — Americans spend an estimated $1.3 billion on fish oil products every year, making them one of the most commonly consumed dietary supplements in the country.

But do you know what’s in your fish oil?

A new documentary, “Supplements and Safety,” pulls back the curtain on some of America’s most popular supplements, and it suggests that many people who buy them may not be getting what they are paying for. The program, airing on the PBS investigative series “Frontline” on Tuesday night, is a collaboration between “Frontline,” The New York Times and The Canadian Broadcasting Corporation.

The program examines the widespread use of potent vitamins, herbs, fish oil and fat-burning supplements. Millions of Americans use these products safely every year. But researchers have found that in many cases they can cause unexpected side effects. And because dietary supplements are largely unregulated by the federal government, adulteration and contamination are common, experts say.

The Frontline documentary investigates large outbreaks of disease tied to tainted vitamins and fat-burning supplements, including one case in which a workout supplement was linked to more than 70 cases of liver damage. The company whose products were at the center of that outbreak, USPlabs, is among 117 companies and individuals that the Justice Department filed criminal and civil enforcement actions against last year.

MSC certified Pharma Marine launches sustainably sourced CodMarine Oil in North America

November 18, 2015 — The following was released by the Marine Stewardship Council:

Norway’s Pharma Marine AS, a leader in the production of premium quality fish oils and omega-3 concepts, and Healthy Directions, a direct-to-consumer nutritional supplement retailer and wholly-owned subsidiary of Helen of Troy Limited (NASDAQ: HELE), have launched the sustainably sourced supplement, Dr. Williams CodMarine® Oil, for the first time in North America. The omega-3 sources in the oil product are fully traceable to sustainable and well-managed Marine Stewardship Council (MSC) certified fisheries. The MSC is the world’s most recognized certification program for sustainable, wild-caught seafood.

Pharma Marine’s CodMarine Omega-3 Fish Oil

MSC certification underscores Pharma Marine’s core values of caring for natural resources and people in a responsible and sustainable manner and supporting healthy oceans. Based on the west coast of Norway near a region where marine oil production dates back more than 130 years, Pharma Marine, an innovator in marine lipids, recently expanded its technologically advanced facility to enable the increased production of premium quality EPA and DHA products from fresh or frozen wild-caught fish. Pharma Marine’s sustainably sourced fish oil product, CodMarine, is traceable to MSC certified fisheries including North East Arctic cod, haddock and saithe.

Leif Kjetil Gjendemsjo, owner of Pharma Marine, said, “We are proud to introduce our sustainably sourced CodMarine product to the U.S. market and help consumers to make a difference and contribute to the health of the world’s oceans. The blue MSC ecolabel on each bottle provides assurance that there is complete traceability of CodMarine fish oil to sustainable and well-managed fisheries.”

Healthy Directions

Pharma Marine’s CodMarine Omega-3 Fish Oil is available in the U.S. through Healthy Directions’ Dr. Williams brand. In line with Healthy Directions’ mission of helping people to lead healthier lives through the core values of responsibility, integrity, and continuous innovation, Dr. Williams has added CodMarine Oil to his product line to offer a sustainable omega-3 fish oil solution to his customers. The expanded line of sustainably sourced supplements offers options to support cardiovascular and other health benefits.

The blue MSC ecolabel enables consumers to make a difference by choosing fish oil that can be traced back to a sustainable fishery.”

MSC certification ensures traceability

The MSC maintains two global standards, one for evaluating the sustainability of fisheries and one for ensuring that seafood products carrying the blue MSC ecolabel are traceable to MSC certified fisheries. To ensure traceability through every step in the chain, Pharma Marine earned MSC Chain of Custody certification, which provides assurance that MSC certified seafood is not mixed with or substituted for non-certified seafood. MSC certification also ensures that seafood products that bear the blue MSC ecolabel can be traced back to a fishery that has been certified as sustainable and well managed against the global, science based MSC Fishery Standard.

“We congratulate Healthy Directions and Pharma Marine on the introduction of the sustainably sourced CodMarine fish oil supplement product to the U.S. market,” said Michael Griff, MSC senior commercial manager, Americas. “By looking for and choosing the blue MSC ecolabel, consumers are able to contribute to the health of the world’s oceans and safeguard seafood supplies for this and future generations.”

Aquaculture And Marine Ingredients Video Premieres At IFFO Annual Conference

October 7, 2015 — After decades of growth, the aquaculture industry continues to expand as a crucial segment of the global seafood market, and sustainably harvested fish meal and fish oil are fueling this growth. In a new video produced by Saving Seafood and released in partnership with IFFO, the trade association representing the marine ingredients industry, and Omega Protein, aquaculture industry leaders and experts discuss the future of fish meal, fish oil and farmed seafood. The video, which premiered on 28th September at IFFO’s Annual Conference in Berlin, is also being made available to the public.

“People talk about fish meal replacements; there really aren’t fish meal replacements, because no one ingredient is going to have everything that fish meal has,” said Dr. Rick Barrows, a Fish Nutritionist at the USDA’s Agricultural Research Service Fish Technology Center in Bozeman, Montana.

Fish meal and fish oil are irreplaceable because they are some of the best sources of the proteins and essential nutrients that are vital to healthy farmed fish. Some of these nutrients, especially omega-3 fatty acids, are an increasingly important part of human diets as well, having been linked to improved heart health and better brain function.

“You and I, like fish, need 40 essential micronutrients,” says Dr. Michael Rubino, Director of the National Oceanic and Atmospheric Administration’s Fisheries Office of Aquaculture. “Forage fish, in the form of fish meal and fish oil happens to be the perfect combination of those micronutrients.”

Inuit Study Adds Twist to Omega-3 Fatty Acids’ Health Story

September 17, 2015 — A study published on Thursday in the journal Science reported that the ancestors of the Inuit evolved unique genetic adaptations for metabolizing omega-3s and other fatty acids. Those gene variants had drastic effects on Inuit’s bodies, reducing their heights and weights.

Rasmus Nielsen, a geneticist at the University of California, Berkeley, and an author of the new study, said that the discovery raised questions about whether omega-3 fats really were protective for everyone, despite decades of health advice. “The same diet may have different effects on different people,” he said.

Food is a powerful force in evolution. The more nutrients an animal can get, the more likely it is to survive and reproduce. Humans are no exception. When we encounter a new kind of food, natural selection may well favor those of us with genetic mutations that help us thrive on it.

Some people, for example, are able to digest milk throughout their lives. This genetic adaptation arose in societies that domesticated cattle thousands of years ago, in such places as Northern Europe and East Africa. People who trace their ancestry to other regions, by contrast, tend to more often be lactose-intolerant.
