One Food Prevents Parkinson’s

For centuries, fish has been known as “brain food.” And now new research shows that it can prevent one of the most devastating diseases of the brain.

Researchers have discovered that a compound unique to fish can prevent Parkinson’s disease.1

For the study to make sense, you need to know a bit about how proteins work in the brain…

Proteins are long chains of amino acids. They are absorbed into specific brain structures to carry out their function. But sometimes, they become tangled with other proteins. When that happens, it’s called aggregation. When brain proteins aggregate, they create long fibrous structures called amyloids.

Amyloids are linked to cognitive decline, Alzheimer’s, and Parkinson’s. 2 3

Scientists have long believed that fish prevents amyloid buildup. But they didn’t know which substance in fish was responsible or what the process was.

Fish Compound Collects the ‘Parkinson’s Protein’

Researchers at Chalmers University of Technology in Sweden looked at a compound called parvalbumin. It’s not in any other food besides fish.

Scientists found that parvalbumin collects something called alpha-synuclein. It’s a protein that forms amyloids. By hoarding synuclein, parvalbumin prevents it from aggregating and producing the amyloids that lead to Parkinson’s and other brain diseases.

Professor Pernilla Wittung-Stafshede led the study. She’s head of the Chemical Biology division at Chalmers.

“Parvalbumin collects up the ‘Parkinson’s protein’ and actually prevents it from aggregating,” she said.

Fish species highest in parvalbumin are:

  • Herring
  • Cod
  • Carp
  • Redfish
  • Sockeye salmon
  • Red snapper

The best time eat fish is in the late summer and fall, according to Nathalie Scheers. She’s an assistant professor who also worked on the parvalbumin study.

“Fish is normally a lot more nutritious at the end of summer because of increased metabolic activity,” she said. “Levels of parvalbumin are much higher in fish after they have had a lot sun. So it could be worthwhile to increase consumption during autumn.”

One more thing… Although fish is generally very healthy, there are some types you should NEVER eat. They’re laden with mercury from water pollution.4

And others are farmed with harsh chemicals and antibiotics. The higher up the food chain a fish is, the more mercury it will have consumed from eating smaller fish. Fish with long lifespans will also have more mercury.

5 Seafoods You Should Never Eat

  1. Imported catfish. It often contains antibiotics banned in the United States. Asian countries commonly use antibiotics to keep fish disease-free despite being raised in dirty water.5
  1. Imported shrimp. They can contain antibiotics, chemical residues, and disease-causing germs. A Consumer Reports test found that 60% of shrimp samples tested contained dangerous bacteria. These included salmonella, E. coli, and MRSA. About 94% of shrimp sold in the U.S. is farmed in Asian countries.6
  1. Swordfish. This is a restaurant favorite. But swordfish is loaded with mercury.
  1. Chilean sea bass. Its white, flaky texture has made it popular. But like swordfish, it contains high levels of mercury.
  1. Bluefin tuna. Most varieties of tuna contain some mercury, but Bluefin tuna has the highest concentrations. It is most often served as sushi.

Other fish to avoid due to mercury content are king mackerel, orange roughy, shark and tilefish. Steer clear of farmed eel. It often contains both polychlorinated biphenyls (PCBs) and mercury.

And surprisingly, the freshwater northern pike is another fish to avoid. Due to its habitat and longevity, the fish can be loaded with mercury.

Editor’s Note: Eating more fish isn’t the only way to slow brain aging. Researchers in Wisconsin revealed they found a way to reverse up to 20 years of aging in just 6 months.
