'Marketers overstate fish oil claims for heart health, study shows,' Washington Post, Aug. 23, 2023. ♥️
- While a diet rich in seafood can lower risk of heart disease, studies havent shown the same benefit from fish oil supplements
Most research shows that over-the-counter fish oil supplements dont offer cardiovascular benefits, but that hasnt stopped marketers from touting them for heart health, a new study shows. The sale of fish oil supplements is a multibillion-dollar industry, and many people take fish oil capsules daily, believing the omega-3 fatty acids they contain are good for their overall health, particularly for their heart.
While its true people who eat seafood regularly are less likely to die of heart disease, studies have not shown that taking fish oil as a supplement offers the same benefit. Even so, fish oil marketers continue to make health claims that imply a wide range of benefits, according to a study published Wednesday in JAMA Cardiology.
The researchers analyzed labels from more than 2,000 fish oil supplements that made health claims. They found more than 80 percent used what is known as a structure and function claim, which is a general description that describes the role of omega-3 fatty acids in the body such as promotes heart health or supports heart, mind and mood. Cardiovascular health claims, which accounted for 62 percent, were most common.
Fish oil contains two omega-3 fatty acids, EPA and DHA, found naturally in fatty fish such as salmon. Higher levels of these omega-3s have been associated with a lower risk of cardiovascular disease, but the observational findings are based on omega-3 levels in the diet, not from supplement use, some experts say. In fact, two recent large clinical trials showed that over-the-counter fish oil supplements do not improve cardiovascular outcomes...https://wapo.st/3YIzuhH

So he threw away his supplements and we eat more fish. We eat it at least twice a week.

(47,800 posts)told me spontaneously when I bought fish oil supplements that most of them went rancid in the capsules. This was in a discount clothing store that sold closeouts from local stores as well. I recall a cancer researcher saying rancidity raises the risk of cancer. I don't doubt his claim. My dad took them for more than 20 years, and guess what?

(47,800 posts)Recall we fought heart disease with trans fats. And cancer with laetrile. And roto-rooter-type demolition of cancer tumors in both men and women.
There is still a school of thought that prostate cancer can be fought with whole milk organic ricotta cheese, sometimes from goat milk. All this nonfat dairy is bunch of hooey!
You are 100% correct. Balanced diet, fresh foods. Get your nutrition from real food!

(7,962 posts)As much as some hate to hear it, most supplements are BS. That's why the ads say things like "supports" such and such. Very, very few of these actually have scientific studies to back up claims. Even something like zinc that has shown some efficacy against colds is only good for ameliorating the symptoms in some but not all, and does not prevent them.
"Brain health" supplements are big business right now, but with one problem: they don't work. From Harvard:

Then our oceans would be filled with perhaps tastier fish.

(12,342 posts)I have been on Icosapent ethyl (Vascepa) prescribed by my cardiologist for years now. It is prescription only and has kept my triglycerides level below 100 when it was chronically above 400.
The dose is 4g daily and if I understand correctly is only one of the Omega 3 fatty acids in fish oil. Also it's synthetic not from fish.

(5,668 posts)clinical research for the NIH looking at the effects of fish oil on cholesterol and triglyceride levels.
Much of the research done- starting in the early 80s - showed that chol and trigly levels could be lowered significantly (by 25-35%). However, most of these studies dosed patients with ~ 10g of fish oil daily. This is a VERY high dose.

Toward the end of the video. He says the Mayo Clinic meta analysis found a significant reduction of heart attacks with a high degree of certainty:

Also, they mention the flaws of the study in this video:

(5,668 posts)astounding things I have ever seen, medically, has never left me.
This was a study set up to look at the effects of fish oil in patients with nephrotic syndrome- a disease of the kidneys that causes the kidney to become sort of like Swiss cheese, allowing large particles like chol and trig through. Hence, these patients tend to have very high chol and trig levels - Ive seen chol 700, trig of 1500!
The study was blinded & tightly controlled- Patient received a controlled diet and were randomized to receive 10g of fish oil or placebo daily, with a washout period of 8 weeks between trials.
Our first patient was a 55 year old, white male who had smoked for 30+ years whose kidneys were significantly damaged. He dropped dead of a heart attack, while shoveling snow, 2 days after completing the study
.
No one will ever know whether, or not, this might have been caused by plaque breaking away from an artery and causing the heart attack.
In any case, what was amazing was that his kidneys were completely healed at the end of the study.
His nephrologist showed us the before and after scans of his kidneys- all signs of nephrotic syndrome were gone.
I will never forget the reaction of all the doctors in the room- stunned silence.
Unfortunately, this was the first & last patient we ever studied, as the MD leading the study moved.
I often wonder if fish oil has more benefits than we know.
