A diet high in antioxidants does more than just ward off cancer. It fights the free radicals responsible for arthritis and other joint diseases, lung problems like emphysema and bronchitis, and atherosclerosis, the leading cause of heart disease. Though you may think that antioxidant-rich foods are limited to expensive goji berries or exotic herbs, research is identifying some dirt-cheap sources of the disease-fighting, anti-inflammatory nutrients. And they cost a lot less than exotic superberries like goji or acai.
1. Black Rice

Researchers from Louisiana have found that black rice could be a very affordable source of good health. For literally pennies, you can feed your family a food that rivals blueberries in its levels of antioxidants. Like fruits, black rice is loaded with anthocyanins, which show promise for fighting heart disease, cancer, and other ills. "Just a spoonful of black rice bran contains more health-promoting anthocyanin antioxidants than are found in a spoonful of blueberries, but with less sugar and more fiber and vitamin E antioxidants," says Zhimin Xu, PhD, associate professor of food science at the Louisiana State University Agricultural Center in Baton Rouge.
2. Sweet Potatoes

This root vegetable is high on the affordable antioxidant-rich food list, says Christina Economos, PhD, associate professor of nutrition at Tufts University in Boston. While certainly not as sexy as a goji berry, sweet potatoes are cheap, and once cured, can be stored for months. So load up at the farmer's market and enjoy them all winter!

Economos also recommends red delicious and Granny Smith apples, two types commonly grown in the U.S. Just be sure to eat the peel—it boosts antioxidant levels up to six times higher than the apples' flesh! (Of course, it's best to buy organic or, to save money, grow your own apple tree!)

You may think dried beans are boring, but certain types—particularly kidney, pinto, black, and navy beans—are packed with not only antioxidants, but also fiber, folic acid, iron, potassium, and zinc. To reduce cooking time and the unwanted gas that sometimes accompanies a meal of beans, soak them overnight, and then rinse well and drain them before cooking. Cook in your pressure cooker to make cooking time even quicker! Organic dried beans are very cheap, so try to avoid canned beans ... the inside of the can is likely coated in the estrogenic chemical bisphenol A (BPA), which is linked to health troubles.

These ruby-red bite-size snacks beat out coffee, blueberries, and even red wine in a 2007 analysis of antioxidant-rich foods published in the American Journal of Clinical Nutrition. Dried cranberries appear to behold even more antioxidant powers than their fresh counterparts.

Coffee, America's most treasured pick-me-up, is also chockfull of disease-fighting antioxidants. As if the fragrant morning wake-up isn't enough, researchers think the combination of caffeine and antioxidants may be significantly reducing heart disease. Just be sure to avoid adding non-dairy creamer to your java—a study published in the Journal of Nutrition earlier this year found it may block valuable antioxidant absorption.
7. Green tea

If coffee's not your thing, turn to green tea, which ranks high in antioxidants just behind coffee. In fact, integrative-medicine expert Andrew Weil suggests choosing tea over coffee because it contains some of the most powerful antioxidants known. Japanese researchers have also shown that women who drink five or more cups of green tea a day slash their risk of dying from heart disease by about 30 percent. We can all drink to that!

After sustained declines in the number of COVID-19 cases over recent months, restrictions are starting to ease across the United States. Numbers of new cases are falling or stable at low numbers in some states, but they are surging in many others. Overall, the U.S. is experiencing a sharp increase in the number of new cases a day, and by late June, had surpassed the peak rate of spread in early April.
Seven day rolling average of number of people confirmed to have COVID-19, per day (not including today). This chart gets updated once per day with data by Johns Hopkins. Johns Hopkins university doesn't provide reliable data for March 12 and March 13. Johns Hopkins CSSE Get the data
To Have a Second Wave, the First Wave Needs to End.<p>A wave of an infection describes a large rise and fall in the number of cases. There isn't a precise epidemiological definition of when a wave begins or ends.</p><p>But with talk of a <a href="https://www.theguardian.com/world/2020/jun/27/new-covid-19-clusters-across-world-spark-fear-of-second-wave" target="_blank">second wave in the news</a>, as an <a href="https://www.american.edu/cas/faculty/mhawkins.cfm" target="_blank">epidemiologist and public health researcher</a>, I think there are two necessary factors that must be met before we can colloquially declare a second wave.</p><p>First, the virus would have to be controlled and transmission brought down to a very low level. That would be the end of the first wave. Then, the virus would need to reappear and result in a large increase in cases and hospitalizations.</p><p>Many countries in <a href="https://doi.org/10.1038/s41562-020-0908-8" target="_blank">Europe and Asia have successfully ended the first wave</a>. <a href="https://www.theguardian.com/world/2020/jun/08/new-zealand-abandons-covid-19-restrictions-after-nation-declared-no-cases" target="_blank">New Zealand</a> and <a href="https://www.newyorker.com/magazine/2020/06/08/how-iceland-beat-the-coronavirus" target="_blank">Iceland</a> have also made it through their first waves and are now essentially coronavirus-free, with very low levels of community transmission and only a handful of active cases currently.</p>
Different States, Different Trends<p>Looking at U.S. numbers as a whole hides what is really going on. Different states are in <a href="https://www.nytimes.com/interactive/2020/us/coronavirus-us-cases.html" target="_blank">vastly different situations right now</a> and when you look at states individually, four major categories emerge.</p><ol><li>Places where the first wave is ending: States in the Northeast and a few scattered elsewhere experienced large initial spikes but were able to mostly contain the virus and substantially brought down new infections. <a href="https://www.nytimes.com/interactive/2020/us/new-york-coronavirus-cases.html" target="_blank">New York</a> is a good example of this.</li><li>Places still in the first wave: Several states in the South and West – see <a href="https://www.nytimes.com/interactive/2020/us/texas-coronavirus-cases.html" target="_blank">Texas</a> and <a href="https://www.nytimes.com/interactive/2020/us/california-coronavirus-cases.html" target="_blank">California</a> – had some cases early on, but are now seeing massive surges with no sign of slowing down.</li><li>Places in between: Many states were hit early in the first wave, managed to slow it down, but are either at a plateau – like <a href="https://www.nytimes.com/interactive/2020/us/north-dakota-coronavirus-cases.html" target="_blank">North Dakota</a> – or are now seeing steep increases – like <a href="https://www.nytimes.com/interactive/2020/us/oklahoma-coronavirus-cases.html" target="_blank">Oklahoma</a>.</li><li>Places experiencing local second waves: Looking only at a state level, <a href="https://www.nytimes.com/interactive/2020/us/hawaii-coronavirus-cases.html" target="_blank">Hawaii</a>, <a href="https://www.nytimes.com/interactive/2020/us/montana-coronavirus-cases.html" target="_blank">Montana</a> and <a href="https://www.nytimes.com/interactive/2020/us/alaska-coronavirus-cases.html" target="_blank">Alaska</a> could be said to be experiencing second waves. Each state experienced relatively small initial outbreaks and was able to reduce spread to single digits of daily new confirmed cases, but are now all seeing spikes again.</li></ol><p>The trends aren't surprising based on how states have been dealing with reopening. The virus will go wherever there are susceptible people and until the U.S. stops community spread across the entire country, the first wave isn't over.</p>
What Could a Second Wave Look Like?<p>It is possible – though at this point it seems unlikely – that the U.S. could control the virus before a vaccine is developed. If that happens, it would be time to start thinking about a second wave. The question of what it might look like depends in large part on everyone's actions.</p><p>The <a href="https://dx.doi.org/10.1086%2F592454" target="_blank">1918 flu pandemic</a> was characterized by a mild first wave in the winter of 1917-1918 that went away in summer. After restrictions were lifted, people very quickly went back to pre-pandemic life. But a second, deadlier strain came back in fall of 1918 and third in spring of 1919. In total, <a href="https://www.cdc.gov/flu/pandemic-resources/1918-commemoration/1918-pandemic-history.htm" target="_blank">more than 500 million people were infected</a> worldwide and upwards of <a href="https://theconversation.com/compare-the-flu-pandemic-of-1918-and-covid-19-with-caution-the-past-is-not-a-prediction-138895" target="_blank">50 million died</a> over the course of three waves.</p><p>It was the combination of a quick return to normal life and a mutation in the flu's genome that made it more deadly that led to the horrific second and third waves.</p><p>Thankfully, the coronavirus appears to be much more <a href="https://doi.org/10.1016/j.meegid.2020.104351" target="_blank">genetically stable</a> than the influenza virus, and thus less likely to mutate into a more deadly variant. That leaves human behavior as the main risk factor.</p><p>Until a <a href="https://theconversation.com/what-needs-to-go-right-to-get-a-coronavirus-vaccine-in-12-18-months-136816" target="_blank">vaccine or effective treatment is developed</a>, the tried-and-true public health measures of the last months – <a href="https://theconversation.com/this-simple-model-shows-the-importance-of-wearing-masks-and-social-distancing-140423" target="_blank">social distancing,</a> <a href="https://theconversation.com/masks-help-stop-the-spread-of-coronavirus-the-science-is-simple-and-im-one-of-100-experts-urging-governors-to-require-public-mask-wearing-138507" target="_blank">universal mask wearing</a>, frequent hand-washing and avoiding crowded indoor spaces – are the ways to stop the first wave and thwart a second one. And when there are surges like what is happening now in the U.S., further reopening plans need to be put on hold.</p>

Gluts of food left to rot as a consequence of coronavirus aren't just wasteful – they're also likely to damage the environment.
Methane on the Rise<p>Not only is this a tragic waste of food at a time when many are going hungry, it is also an <a href="https://donatedontdump.net/2014/07/07/the-effects-of-food-waste-on-the-environment-by-junemy-pantig/" target="_blank">environmental hazard</a> and could contribute to global warming. Landfill gas – <a href="https://www.epa.gov/lmop/basic-information-about-landfill-gas" target="_blank">roughly half methane and half carbon dioxide (CO2)</a> – is a natural byproduct of the decomposition of organic material.</p>
Food decay leads to production of greenhouse gases, methane and carbon dioxide. EPA<p>Methane is a potent greenhouse gas, 28 to <a href="https://www.ipcc.ch/site/assets/uploads/2018/02/SYR_AR5_FINAL_full.pdf" target="_blank">36 times more effective than CO2 at trapping heat</a> in the atmosphere over a 100-year period, according to the Intergovernmental Panel on Climate Change.</p><p>"Many export-oriented producers produce volumes far too large for output to be absorbed in local markets, and thus <a href="https://unctad.org/en/pages/newsdetails.aspx?OriginalVersionID=2333" target="_blank">organic waste levels have mounted substantially</a>," says Robert Hamwey, Economic Affairs Officer at UN agency UNCTAD. "Because this waste is left to decay, levels of methane emissions, a greenhouse gas, from decaying produce are expected to rise sharply in the crisis and immediate post-crisis months."</p>
Food supply chains are easily disrupted. UN FAO<p>Dumping food was already a problem before the crisis. In America alone, <a href="https://www.refed.com/?sort=economic-value-per-ton" target="_blank">$218 billion is spent growing, processing, transporting</a> and disposing of food that is never eaten, estimates ReFED, a collection of business, non-profit and government leaders committed to reducing food waste. That's equivalent to around 1.3% of GDP.</p><p>Since the pandemic took hold, <a href="https://www.bbc.co.uk/news/world-52267943" target="_blank">farmers are dumping 14 million liters</a> of milk each day because of disrupted supply routes, estimates Dairy Farmers of America. A chicken processor was forced to <a href="https://www.nytimes.com/2020/04/11/business/coronavirus-destroying-food.html" target="_blank">destroy 750,000 unhatched eggs a week</a>, according to the New York Times, which also cited an onion farmer letting most of his harvest decompose because he couldn't distribute or store them.</p>
Food Prices Collapsing<p>The excess has also seen prices collapse. The <a href="http://www.fao.org/worldfoodsituation/foodpricesindex/en/" target="_blank">FAO Food Price Index</a> (FFPI) averaged 162.5 points in May 2020, down 3.1 points from April and reaching the lowest monthly average since December 2018. The gauge has dropped for four consecutive months, and the latest decline reflects falling values of all the food commodities – dairy, meat, cereal, vegetable – except sugar, which rose for the first time in three months.</p><p>All this while the pandemic is exacerbating other global food trends.</p><p>"This year, some 49 million extra people may fall into extreme poverty due to the COVID-19 crisis," said António Guterres, Secretary-General of the UN. "The number of people who are acutely food or nutrition insecure will rapidly expand. <a href="https://www.youtube.com/watch?v=fGhLKAbNDiY&feature=youtu.be" target="_blank">Even in countries with abundant food, we see risks of disruptions in the food supply chain</a>."</p>
