7 Foods That Protect Your Skin from the Sun's Harmful Rays (You'll Love #5)
Now that summer has arrived, sun protection is a must. Most of us are used to reaching for sunscreens, wide-brimmed hats and protective sun gear. While chronic UV exposure is the most predictive factor for skin diseases, we know that inflammation, oxidative stress and DNA damage all play an important role in determining how extensive the damage from the sun can be.

Fortunately, these foods can help you guard against these risk factors and protect your skin against the sun's harmful rays.
1. Olive Oil
High in vitamin E and polyphenols, daily ingestion of unheated olive oil can protect your skin. Vitamin E has been shown in numerous studies to protect against oxidative stress and reduce photo damage from UVB radiation. A number of studies have come out recently pointing to the sun-protective benefits of topical olive oil use, as well. Add one tablespoon of a cold-pressed olive oil to your salads or sprinkle it on your already cooked or roasted veggies. This popular oil should be a part of your daily summer diet and summer skin care.
Well-known now for containing omega-3 fats, walnuts have also been found to protect your skin. Walnuts help the cells in your outer layer of skin fight UV radiation by preventing cell breakdown, or apoptosis. Grab a handful of walnuts for a skin-protecting snack on the go, or grind walnuts in your food processor or blender to add to summertime dips and sauces.
Apples have the highest concentration of polyphenols of any fruit, which means they are a powerhouse when it comes to summer skin care. Polyphenols are plant-based compounds that help regulate inflammation, oxidative stress and the immune system. An apple a day this summer can protect your skin and your immune system.
4. Tea and Coffee
Another source of polyphenols, tea and coffee also act as antioxidants that can boost skin health. A recent study found that daily coffee consumption protected a group of Japanese patients from photo-aging and hyper-pigmented sunspots, due to the drinks' high polyphenol content—another reason to keep drinking your daily cup of coffee, even in the summer heat.
5. Red Wine
While many of us avoid wine because we are limiting calories or sugar, red wine does have high polyphenol content. No excuses needed here. Consider having two to three glasses of red wine a week for an additional alternative source of antioxidants.
Broccoli, like apples, is a polyphenol champ. It's the vegetable with the highest count of polyphenols. As a cruciferous vegetable, broccoli also fights inflammation, with recent studies showing broccoli sprouts to be helpful in protecting against cancer. A compound in broccoli, sulphorane, has been shown to activate our skin's defense system when we are exposed to UV light.
This kitchen favorite may be the most protective herb when it comes to sun protection. Basil contains an antioxidant zeaxanthin that helps filter UV light from the retina, protecting your eyes.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.
Sweden is a world leader in renewable energy consumption. Swedish Institute/World Bank
Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
