Why You May Need to Re-Think Taking Those Fish Oil Supplements

Long touted as a key to improved cardiovascular health, increased cognition, and other benefits, omega-3 supplements are facing increasing scrutiny over whether they work as advertised. If recent critical investigation is correct, you might be enduring fish burps for little to no benefit.

Reviewing the new book The Omega Principle by Paul Greenberg in Slate, Irineo Cabreros breaks down the dilemma facing the $15 billion omega-3 supplement industry. A recent meta-analysis that looked at 79 studies involving more than 100,000 subjects found that omega-3 consumption had virtually no effect on common heart conditions. An earlier examination of studies compiled in 2012 also found that supplementing with omega-3s had no impact on whether a person died as a result of a cardiac event. Consumption also had no impact on overall mortality. Studies that have looked at fish oil’s benefits when it comes to psychiatric conditions like depression have been similarly inconclusive.

So why do we believe omega-3s are synonymous with better health? The notion originally stemmed from research into an Inuit population in Greenland in the 1970s. The Inuit had low incidences of heart problems and ate a lot of fatty fish. The conclusion was that their oily fish-based diets had protective effects on the heart. Ever since, supplement companies and consumers have associated fish oil, in liquid or capsule form, as having a host of cardiovascular benefits. But more contemporary research illustrates that the Inuit might simply metabolize their fish-heavy diet differently, leading to effects that can’t necessarily be replicated in a general population.

While fish oil may not improve heart health, it’s not likely to do you any harm. Unfortunately, the same may not hold true for the environment. According to Greenberg’s book, supplement companies typically draw the raw material for their products from large quantities of forage fish that are captured for their oil and agricultural value as fertilizer and animal feed—up to 27 tons annually. Forage species like anchovies and krill play a key role in the aquatic ecosystem: As prey species, they transmit solar energy from plankton to larger carnivorous fish. If companies continue to winnow their population, it’s possible their absence could have unintended and unpredictable effects on food chains. Greenberg argues that continuing to weaken fish populations for supplements of dubious value may be something we’ll come to regret.

In the meantime, one thing experts can agree on is that eating actual fish is good for your body. The American Heart Association recommends eating two 3.5-ounce servings of fish like salmon, mackerel, herring, and albacore tuna weekly.

7 Quick Tips for Disinfecting Your Home the Smart Way

With many people spending more time—or virtually all of their time—indoors, it’s natural for thoughts to turn to how to best clean surfaces that might help minimize the risk of spreading illness. Although researchers believe respiratory droplets are the primary way coronavirus is transmitted, preliminary data, which is not yet peer-reviewed, suggests the virus may remain on some surfaces for hours or days.

While scrubbing isn't a complex process, there are nonetheless some areas of your home you might be neglecting. Here’s how to best approach a household scrub, as well as identify and disinfect some common germ hot spots.

1. Pay attention to high-touch surfaces and clean them frequently.

High-touch surfaces are exactly what they sound like: Areas in the home that get handled and touched regularly. Think doorknobs, light switches, appliance handles, toilet handles, faucets, and remotes. And don’t forget laptops, keyboards, desks, and phones.

2. Don't just do a quick wipe down. Get the entire surface.

Taking a disinfecting wipe to the keyhole of a doorknob isn’t going to do you much good—it's important to really scrub all high-touch surfaces. Make sure you get every available surface area, including the plate behind the knob where fingers and hands often brush against it. When cleaning remotes, make sure you don't just scrub the buttons, but the space between them as well.

3. You can use soap and water.

While products claiming to kill 99.9 percent of germs are best in this scenario, there's another option if you're having a hard time tracking down those supplies—simply mix some dish soap in water. It won’t kill organisms, but it can remove them from the surface. (And while soap and water can work for high-touch surfaces throughout the home, you shouldn't use the solution on electronics like your remote or keyboard.)

If you’re looking to kill germs, diluted bleach (four teaspoons to one quart of water) and 70 percent alcohol solutions work well. But it's important to note that bleach and other cleaners can harm certain surfaces. So be sure to do your research and make sure the product you're using won't cause any damage before you start scrubbing.

4. Take laundry precautions.

If you’re trying to be extra-vigilant about the spread of germs in the house, you should consider washing clothes at the highest possible temperature and disinfecting laundry bins. It’s also advisable to use disposable laundry bags.

5. Remove your shoes before entering the house.

This step is more preventative, but it’s a simple way to keep from tracking in contaminants. Remove your shoes before going inside and leave them near the door. It's also a good idea to clean floor surfaces with disinfecting mop cloths, but be sure anything you use is safe for the finished surface. Cleaners like bleach can discolor certain materials.

6. Don't forget to clean your car.

Even people vigilant about cleaning their home can neglect their car interior. Since you’re constantly touching virtually every surface, be sure to wipe everything down regularly, including the steering wheel and door handles. If you have a leather interior, there are auto wipes available for those surfaces. And before you go wipe down any touchscreens, be sure to check your owner’s manual to see if they require any special microfiber cloth.

7. Give your debit cards a wipe.

It’s a good idea to disinfect credit or debit cards that follow you around on shopping excursions. As with all high-touch objects, be sure to wipe them down every day.

The World Health Organization Is Releasing a COVID-19 App to Combat Coronavirus Misinformation

As is the case with most crises, the novel coronavirus has become a breeding ground for misinformation. Because the disease is so new, there are a lot of unanswered questions surrounding it, but that hasn't stopped people from claiming to know how to treat, prevent, and detect COVID-19. In an effort to separate fact from fiction, the World Health Organization (WHO) is launching an app dedicated to sharing what we know and don't know about the virus, 9to5Google reports.

Named WHO MyHealth, the new app is a collaboration between former Google and Microsoft employees, WHO advisors and ambassadors, and other tech and health experts. Users will be able to compare their symptoms with those linked to COVID-19 and receive public health updates specific to their location. As of now, there are plans to invite people who have been either been diagnosed with or exposed to COVID-19 to share their phone's location history to give experts a better idea of how the virus spreads.

WHO MyHealth, which is currently being built as open source, is set to roll out for Android and iOS on Monday, March 30. If you have questions about COVID-19 you need answered immediately, you can also access accurate and up-to-date information through the WHO's chatbot.

Any information regarding novel coronavirus should be met with skepticism when it can't be traced back to organizations like the WHO or the CDC—especially when it comes to supposed cures. No specific medication has been proven to treat or prevent COVID-19, so you shouldn't take advice from anyone claiming otherwise.
