Is Apple Cider Vinegar Good for You? A Doctor Weighs In
By Gabriel Neal
But it wasn't just for the fish.
It was for the vinegar—malt vinegar. We would uncap a bottle at the table and swig that tangy, delicious nectar of the gods straight.
Are most of you repulsed? Probably. Were we way ahead of our time? Apparently.
Some social media and online searches would have us believe that drinking vinegar is a cure-all. Our friends and colleagues will regale us with stories of the healing power of apple cider vinegar for whatever problem we may have just mentioned. "Oh, that backache from mowing? Vinegar." "That last 10 pounds? Vinegar will melt that right off." "Syphilis, again? You know it—vinegar."
As a practicing physician and professor of medicine, people ask me about the benefits of drinking apple cider vinegar all the time. I enjoy those moments, because we can talk about the (extensive) history of vinegar, and then distill the conversations to how it could, maybe, benefit them.
A cure for colds, the plague and obesity?
Historically, vinegar has been used for many ailments. A few examples are that of the famous Greek physician Hippocrates, who recommended vinegar for the treatment of cough and colds, and that of the Italian physician Tommaso Del Garbo, who, during an outbreak of plague in 1348, washed his hands, face and mouth with vinegar in the hopes of preventing infection.
Vinegar and water has been a refreshing drink from the time of Roman soldiers to modern athletes who drink it to slake their thirst. Ancient and modern cultures the world over have found good uses for "sour wine."
While there is plenty of historical and anecdotal testimony to the virtues of vinegar, what does medical research have to say on the subject of vinegar and health?
The most reliable evidence for the health benefits of vinegar come from a few humans studies involving apple cider vinegar. One study demonstrated that apple cider vinegar can improve after-meal blood glucose levels in insulin-resistant subjects. In 11 people who were "pre-diabetic," drinking 20 milliliters, a little more than one tablespoon, of apple cider vinegar lowered their blood sugar levels 30-60 minutes after eating more than a placebo did. That's good—but it was only demonstrated in 11 pre-diabetic people.
Another study on obese adults demonstrated a significant reduction in weight, fat mass and triglycerides. Researchers selected 155 obese Japanese adults to ingest either 15 ml, about one tablespoon, or 30 ml, a little more than two tablespoons, of vinegar daily, or a placebo drink, and followed their weight, fat mass and triglycerides. In both the 15 ml and 30 ml group, researchers saw a reduction in all three markers. While these studies need confirmation by larger studies, they are encouraging.
Studies in animals, mostly rats, show that vinegar can potentially reduce blood pressure and abdominal fat cells. These help build the case for followup studies in humans, but any benefit claims based only on animal studies is premature.
In all, the health benefits we suspect vinegar has need to be confirmed by larger human studies, and this will certainly happen as researchers build on what has been studied in humans and animals to date.
Is there any harm in it?
Is there any evidence that vinegar is bad for you? Not really. Unless you are drinking excessive amounts of it (duh), or drinking a high acetic acid concentration vinegar such as distilled white vinegar used for cleaning (consumable vinegar's acetic acid content is only 4 to 8 percent), or rubbing it in your eyes (ouch!), or heating it in a lead vat as the Romans did to make it sweet. Then, yeah, that's unhealthy.
Also, don't heat any kind of food in lead vats. That's always bad.
So have your fish and chips and vinegar. It's not hurting you. It may not be doing you all the good that you're hoping that it will; and it certainly is not a cure-all. But it is something that people all over the world will be enjoying with you. Now raise high that bottle of malt vinegar with me, and let's drink to our health.

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
