10 Anti-Aging Superfoods That Keep Your Skin Healthy
By Lauren Kessler
True, food isn't everything, but much of the hope (and hype) surrounding the anti-aging movement is focused on food and in particular on what are being called "superfoods." This is not a scientific term. It is not a term used by dietitians or nutritional scientists.
A superfood is a food particularly rich in vitamins, minerals, antioxidants, amino acids, enzymes and other essential nutrients with proven health benefits. It has more of the good stuff per calorie than other foods and fewer (or none) of the properties considered to be negative.
And when it comes to your skin, these are the top 10 foods you should always eat:
Broccoli—the "eat it, it's good for you" food that George Bush (the elder) proclaimed his distaste for—is one of the most nutrient-dense foods on Earth. It has protein; bone-building calcium; fiber; vitamins A, C and K; a phytoestrogen shown to benefit cognitive skills; and a chemical that, at least in animal studies, reversed age-related damage to body tissues and organs. Done.
Blueberries are one of the U.S. Department of Agriculture's (USDA) top ORAC foods. That stands for "oxygen radical absorbance capacity," which means these foods are antioxidant powerhouses that, as the USDA says, "attack aging at its roots" and can "help slow down the effects of aging in humans" by protecting the body against cellular damage. (Remember the pollution caused by those cellular engines, mitochondria?) Or that's what the USDA used to say.
Recently, the agency has recanted, removing the ORAC list from its Web site because "metabolic pathways are not completely understood and non-antioxidant mechanisms [are] still undefined."
In other words: More research is needed. But studies at Tufts support the "powerhouse food" approach, finding that several compounds in blueberries help to mitigate inflammation. (Inflammation has been linked to just about every disease of aging).
It's one of the richest sources of omega-3 fatty acids, which help to lower cholesterol, prevent blood platelets from sticking to artery walls, decrease inflammation, decrease the risk of strokes and prevent heart attacks. Salmon has lots of protein, is a good source of iron and is low in mercury—a concern for fish lovers. In 2009, Madonna went on a well-publicized salmon binge to "knock 12 years off her appearance," as the Boston Globe reported. Hard to separate the effects of salmon, a 24-7 personal trainer and possible skilled plastic surgery, but the woman looks amazing.
Almonds (walnuts too and pistachios) are proven reducers of bad cholesterol. Like broccoli, they are rich in a type of antioxidant thought to be instrumental in battling free radical damage. They're high in fiber, in phytochemicals that may protect against cancer and in arginine, a precursor to human growth hormone. They are also high in calories, so limit the amount you consume.
Beans also make the short list because they are very high in soluble fiber, which has been linked to lower risks of heart disease, diabetes and certain cancers; reduced cholesterol and blood glucose levels; lower blood pressure; and less inflammation.
Sweet potatoes, with their prodigious vitamin A content (good for the skin and eyes), their host of powerful antioxidants and their potassium, which helps blunt the effects of sodium on blood pressure and bone loss, are nutritional powerhouses. If you grew up thinking sweet potatoes appeared on the dinner table only once a year, topped with brown sugar and mini marshmallows, that's no way to treat a top 10 superfood.
The Greek-style kind (thicker and creamier) has triple or more the protein of regular yogurt. Yogurt is calcium rich, like milk (and can be tolerated by many of the lactose intolerant), and is full of what is euphemistically called "active cultures"—better than saying it's good for you because it's loaded with bacteria. But it's the good kind, the gut-enhancing kind.
Quinoa (KEEN-wah) is the only grain on the list. It's high in protein, fiber and iron. Besides, the National Aeronautics and Space Administration scientists tasked with feeding astronauts in space chose it because it supplied the most "essential life-sustaining nutrients" of any single food. What they meant was that it contained all the essential amino acids and was thus a complete protein—not that it contained every nutrient needed to sustain life.

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>
