9 Ways to Skip the Pharmacy and Use Superfoods As Your Medicine
The most powerful tool you have to change your brain and your health is your fork. Food is not just calories or energy. Food contains information that talks to your genes, turning them on or off and affecting their function moment to moment.

Food is the fastest acting and most powerful medicine you can take to change your life. We call this nutrigenomics. Think of your genes as the software that runs everything in your body. Just like your computer software, your genes only do what you instruct them to do with the stroke of your keyboard.
The foods you eat are the keystrokes that send messages to your genes telling them what to do—creating health or disease.
Imagine what messages you are sending with a double cheeseburger, large fries and a 48-ounce cola. Then consider what messages you might send instead with deep red wild salmon, braised greens and brown rice.
The science of nutrigenomics allows us to personalize medicine. Not everyone with the same problems needs the same prescription. Your individual genetic makeup determines what you need to be optimally healthy.
Consider that you only have about 30,000 genes, but those genes contain about 3 million tiny variations called single nucleotide polymorphisms (SNPs) that make up who you are. These variations make your individual needs slightly different from my individual needs.
Put another way, we all have different needs for food, vitamins, rest, exercise, stress tolerance or ability to handle toxins.
The key, then, becomes personalizing a program based on your strengths and vulnerabilities—your individual needs. By analyzing where you are out of balance and then applying the science of nutrigenomics to help reestablish balance, you can design a treatment matched to your individual needs.
Personalizing doesn’t have to be complicated. The first step is to take out the bad stuff, or the things that create imbalance. Those imbalances include a nutrient-poor, processed diet, toxins, allergens, infections and stress.
Think of it this way. If you have 10 tacks in your foot, you can’t take out one, pop an aspirin and hope to feel better. You need to find and take out all the tacks; taking out just one of them won’t make you better.
The second step is to add the good stuff, including high-quality whole foods, nutrients, water, oxygen, light, movement, sleep, relaxation, community, connection, love, meaning and purpose. When you add those good things, the body’s natural intelligence and healing system will take care of the rest.
Using this simple yet comprehensive method—removing the bad things and replacing them with good things—allows me to treat virtually all diseases, whether they are “in the brain” or “in the body.” This strategy works for one simple reason: the body and the brain are one system.
Upgrade Your Genes; Downsize Your Jeans
As I mentioned before, food is information. If you want to turn off the genes that lead to diabesity and turn on the genes that lead to health, the key becomes the quality and type of food you eat, not necessarily the number of calories you consume or the ratio of protein to fat to carbohydrate in your diet. You need to put your genes on a diet.
As David Ludwig, one of the leading obesity researchers at Harvard Medical School, said, “Molecular pathways involved in hormone action [like insulin resistance] have been the target of a multibillion-dollar pharmaceutical research effort. However, many of these pathways may normally be under dietary regulation. The results of the present study [on nutrigenomics] emphasize the age-old wisdom to ‘use food as medicine’—in this case, for the targeted prevention and treatment of obesity, diabetes and heart disease.”
Shifting from a nutrient-poor diet to a nutrient-rich diet abundant in plant foods such as fruits, vegetables, nuts, seeds, beans and whole grains improves the expression of hundreds of genes that control insulin function and obesity.
To use just one example, the vast array of colors in vegetables represents over 25,000 beneficial chemicals.
Our hunter-gatherer ancestors ate over 800 varieties of plant foods. Today, we don’t even consume a fraction of that amount. We need to make an extra effort to eat many different foods to get the full range of benefits. Remember: eat the rainbow!
An optimal diet to prevent and treat diabesity also includes healthy fats such as olive oil, nuts, avocados, and omega-3 fats, along with modest amounts of lean animal protein. This is commonly known as a Mediterranean diet. It is a diet of whole, real, fresh food that has been prepared in a kitchen, not a factory.
This way of eating has been shown to prevent and even reverse diabesity. It has broad-ranging benefits for our health, and beneficially affects our entire physiology, reducing inflammation, boosting detoxification, balancing hormones and providing powerful antioxidant protection—all things that fix the underlying causes of disease.
Even with a perfect diet, the combination of our depleted soils, the storage and transportation of our food, genetic alterations of traditional heirloom species, and the increased stress and nutritional demands resulting from a toxic environment make it impossible for us to get the vitamins and minerals we need solely from the foods we eat. The evidence shows that we cannot get away from the need for nutritional supplements.
That’s why you need a full complement of vitamins and minerals, and you may need to individually correct specific deficiencies, including deficiencies in chromium, biotin, vitamin D, magnesium, zinc, alpha lipoic acid, and omega-3 fats.
Fiber is a great blood sugar stabilizer to reverse diabesity, but unfortunately most of us do not eat enough high-fiber plant foods. That’s why I also recommend glucomannan, a soluble fiber derived from an Asian potato-like tuber.
Also called Konjac fiber, glucomannan is much more viscous than usual fibers, retaining up to 17 times its weight in water. Expanding in the stomach, small and large intestine, it absorbs fat, accelerates elimination, reduces cholesterol, blunts sugar absorption and facilitates weight loss, in part by increasing feelings of satiety.
Nine Ways to Make Your Grocery Store a “Farmacy”
I hope I have demonstrated that what you put at the end of your fork is a more powerful medicine than anything you will find at the bottom of a pill bottle. Food is the most powerful medicine available to heal chronic disease, which will account for over 50 million deaths and cost the global economy $47 trillion by 2030. That’s why we must change our perspective about food.
All you need to do is eat your medicine and think of your grocery store as your pharmacy. Here are nine ways to do that:
1. Skip the labels: Whenever possible, do not buy foods with labels. Avoid foods in a box, package or can.
2. Keep it simple: If the food does have a label, it should have fewer than five ingredients. Beware of food with “health claims” on the label. Cola is “fat free.” That doesn’t make it healthy.
3. Steer clear of the white menaces: Stay away from white sugar and white flour, which acts like sugar in your body. Learn the numerous disguises for sugar and get rid of any food that contains them.
4. Dump this lethal sugar: Throw out any food with high fructose corn syrup (HFCS) on the label. You already know it is not good for you, but just in case you need reminding, read this blog for the five reasons HFCS will kill you.
5. Avoid this bad fat: Eliminate any food with the word “hydrogenated” on the label, which translates into trans fats.
6. Stick to healthy oils: Throw out any highly refined cooking oils such as corn oil and soy oil. Choose olive oil and coconut oil instead.
7. Recognize your ingredients: Throw out any food with ingredients you don’t recognize or can’t pronounce.
8. Watch for these red flags: Toss foods with preservatives, additives, coloring, dyes or “natural flavorings” like MSG.
9. Ditch artificial sweeteners: Remember that food is information, not just calories. Diet sodas and other foods and drinks with artificial sweeteners are almost always calorie free, but they will still make you fat.
When in Doubt, Stick with this One Rule
If it came from the earth or a farmer’s field and not a food chemist’s lab, then it is safe to eat. Like Michael Pollan, author of Food Rules, says, “If it came from a plant, eat it; if it was made in a plant, don’t.” It is really that simple.

The vast majority of SARS-CoV-2 transmission occurs indoors, most of it from the inhalation of airborne particles that contain the coronavirus. The best way to prevent the virus from spreading in a home or business would be to simply keep infected people away. But this is hard to do when an estimated 40% of cases are asymptomatic and asymptomatic people can still spread the coronavirus to others.
It’s All About Fresh, Outside Air<p>The safest indoor space is one that constantly has lots of <a href="https://www.epa.gov/indoor-air-quality-iaq/how-does-outdoor-air-enter-building" target="_blank">outside air</a> replacing the stale air inside.</p><p>In commercial buildings, <a href="https://www.ncbi.nlm.nih.gov/books/NBK143277/" target="_blank">outside air is usually pumped in</a> through heating, ventilating and air-conditioning (HVAC) systems. In <a href="https://www.epa.gov/indoor-air-quality-iaq/how-does-outdoor-air-enter-building" target="_blank">homes, outside air gets in</a> through open windows and doors, in addition to seeping in through various nooks and crannies.</p><p>Simply put, the more fresh, outside air inside a building, the better. Bringing in this air dilutes any contaminant in a building, whether a virus or a something else, and <a href="https://doi.org/10.1111/j.1600-0668.2010.00703.x" target="_blank">reduces the exposure of anyone inside</a>. Environmental engineers like me quantify how much outside air is getting into a building using a measure called the <a href="https://doi.org/10.1038/jes.2013.30" target="_blank">air exchange rate</a>. This number quantifies the number of times the air inside a building gets replaced with air from outside in an hour.</p><p>While the exact rate depends on the number of people and size of the room, most experts consider roughly <a href="https://doi.org/10.1034/j.1600-0668.2002.01145.x" target="_blank">six air changes an hour</a> to be good for a 10-foot-by-10-foot room with three to four people in it. In a pandemic this should be higher, with one study from 2016 suggesting that an exchange rate of nine times per hour <a href="https://doi.org/10.1177%2F1420326X16631596" target="_blank">reduced the spread of SARS, MERS and H1N1</a> in a Hong Kong hospital.</p><p>Many buildings in the U.S., <a href="https://doi.org/10.1111/ina.12403" target="_blank">especially schools</a>, do not meet recommended ventilation rates. Thankfully, it can be pretty easy to get more outside air into a building. Keeping <a href="https://doi.org/10.1016/S0960-1481(99)00012-9" target="_blank">windows and doors open</a> is a good start. Putting a box fan in a window blowing out can greatly increase air exchange too. In buildings that don't have operable windows, you can change the mechanical ventilation system to increase how much air it is pumping. But in any room, the more people inside, the faster the air should be replaced.</p>
Using CO2 to Measure Air Circulation<p>So how do you know if the room you're in has enough air exchange? It's actually a pretty hard number to calculate. But there's an easy-to-measure proxy that can help. Every time you exhale, you <a href="https://doi.org/10.1111/ina.12383" target="_blank">release CO2</a> into the air. Since the coronavirus is most often spread by breathing, coughing or talking, you can use <a href="https://pdfs.semanticscholar.org/dd7e/b2870c38f70e5285e5118ed6f158c091f7cf.pdf" target="_blank">CO2 levels</a> to see if the room is filling up with potentially infectious exhalations. The CO2 level lets you estimate if enough fresh outside air is getting in.</p><p>Outdoors, CO2 levels are just above 400 parts per million (ppm). A well ventilated room will have around <a href="https://doi.org/10.1111/j.1600-0668.1999.00003.x" target="_blank">800 ppm of CO2</a>. Any higher than that and it is a sign the room might need more ventilation.</p><p>Last year, researchers in Taiwan reported on the <a href="https://doi.org/10.1111/ina.12639" target="_blank">effect of ventilation on a tuberculosis outbreak</a> at Taipei University. Many of the rooms in the school were underventilated and had CO2 levels above 3,000 ppm. When engineers improved air circulation and got CO2 levels under 600 ppm, <a href="https://doi.org/10.1111/ina.12639" target="_blank">the outbreak completely stopped</a>. According to the research, the increase in ventilation was responsible for 97% of the decrease in transmission.</p><p>Since the coronavirus is spread through the air, higher CO2 levels in a room likely mean there is a <a href="https://doi.org/10.1111/ina.12639" target="_blank">higher chance of transmission</a> if an infected person is inside. Based on the study above, I recommend trying to keep the CO2 levels below 600 ppm. You can buy <a href="https://doi.org/10.5194/amt-7-3325-2014" target="_blank">good CO2 meters</a> for around $100 online; just make sure that they are accurate to within 50 ppm.</p>
Air Cleaners<p>If you are in a room that can't get enough outside air for dilution, consider an air cleaner, also commonly called air purifiers. These machines remove particles from the air, usually using <a href="https://doi.org/10.1016/j.cap.2005.07.013" target="_blank">a filter</a> made of tightly woven fibers. They can <a href="https://shellym80304.files.wordpress.com/2020/06/miller-leiden-et-al-1996.pdf" target="_blank">capture particles containing bacteria and viruses</a> and can help reduce disease transmission.</p><p>The U.S. Environmental Protection Agency says that <a href="https://www.epa.gov/coronavirus/air-cleaners-hvac-filters-and-coronavirus-covid-19" target="_blank">air cleaners can do this for the coronavirus</a>, but not all air cleaners are equal. Before you go out and buy one, there are few things to keep in mind.</p><p>The first thing to consider is <a href="https://shellym80304.files.wordpress.com/2020/06/air-cleaner-report.pdf" target="_blank">how effective an air cleaner's filter is</a>. Your best option is a cleaner that uses a high-efficiency particulate air (<a href="https://doi.org/10.1016/S0021-8502(05)80214-9" target="_blank">HEPA</a>) filter, as these remove more than <a href="https://doi.org/10.1063/1.2771421" target="_blank">99.97% of all particle sizes</a>.</p><p>The second thing to consider is how powerful the cleaner is. The bigger the room – or the more people in it – the more air needs to be cleaned. I worked with some colleagues at Harvard to put together a tool to help teachers and schools determine <a href="https://docs.google.com/spreadsheets/d/1NEhk1IEdbEi_b3wa6gI_zNs8uBJjlSS-86d4b7bW098/edit#gid=1275403500" target="_blank">how powerful of an air cleaner you need for different classroom sizes</a>.</p><p>The last thing to consider is the validity of the claims made by the company producing the air cleaner.</p><p>The Association of Home Appliance Manufacturers certifies air cleaners, so the AHAM Verifide seal is a good place to start. Additionally, the California Air Resources Board has a <a href="https://ww2.arb.ca.gov/our-work/programs/air-cleaners-ozone-products/california-certified-air-cleaning-devices" target="_blank">list of air cleaners</a> that are certified as safe and effective, though not all of them use HEPA filters.</p>
Keep Air Fresh or Get Outside<p>Both the <a href="https://www.who.int/news-room/commentaries/detail/transmission-of-sars-cov-2-implications-for-infection-prevention-precautions" target="_blank">World Health Organization</a> and <a href="https://www.cdc.gov/coronavirus/2019-ncov/daily-life-coping/deciding-to-go-out.html" target="_blank">U.S. Centers for Disease Control and Prevention</a> say that poor ventilation increases the risk of transmitting the coronavirus.</p><p>If you are in control of your indoor environment, make sure you are getting enough fresh air from outside circulating into the building. A CO2 monitor can help give you a clue if there is enough ventilation, and if CO2 levels start going up, open some windows and <a href="https://www.advisory.com/daily-briefing/2020/07/17/outdoor-gathering" target="_blank">take a break outside</a>. If you can't get enough fresh air into a room, an air cleaner might be a good idea. If you do get an air cleaner, be aware that they don't remove CO2, so even though the air might be safer, CO2 levels could still be high in the room.</p><p>If you walk into a building and it feels hot, stuffy and crowded, chances are that there is not enough ventilation. Turn around and leave.</p><p>By paying attention to air circulation and filtration, improving them where you can and staying away from places where you can't, you can add another powerful tool to your anti-coronavirus toolkit.</p>

The tiny island nation of Mauritius, known for its turquoise waters, vibrant corals and diverse ecosystem, is in the midst of an environmental catastrophe after a Japanese cargo ship struck a reef off the country's coast two weeks ago. That ship, which is still intact, has since leaked more than 1,000 metric tons of oil into the Indian Ocean. Now, a greater threat looms, as a growing crack in the ship's hull might cause the ship to split in two and release the rest of the ship's oil into the water, NPR reported.
On Friday, Prime Minister Pravind Jugnauth declared a state of environmental emergency.
France has sent a military aircraft carrying pollution control equipment from the nearby island of Reunion to help mitigate the disaster. Additionally, Japan has sent a six-member team to assist as well, the BBC reported.
The teams are working to pump out the remaining oil from the ship, which was believed to be carrying 4,000 metric tons of fuel.
"We are expecting the worst," Mauritian Wildlife Foundation manager Jean Hugues Gardenne said on Monday, The Weather Channel reported. "The ship is showing really big, big cracks. We believe it will break into two at any time, at the maximum within two days. So much oil remains in the ship, so the disaster could become much worse. It's important to remove as much oil as possible. Helicopters are taking out the fuel little by little, ton by ton."
Sunil Dowarkasing, a former strategist for Greenpeace International and former member of parliament in Mauritius, told CNN that the ship contains three oil tanks. The one that ruptured has stopped leaking oil, giving disaster crews time to use a tanker and salvage teams to remove oil from the other two tanks before the ship splits.
By the end of Tuesday, the crew had removed over 1,000 metric tons of oil from the ship, NPR reported, leaving about 1,800 metric tons of oil and diesel, according to the company that owns the ship. So far the frantic efforts are paying off. Earlier today, a local police chief told BBC that there were still 700 metric tons aboard the ship.
The oil spill has already killed marine animals and turned the turquoise water black. It's also threatening the long-term viability of the country's coral reefs, lagoons and shoreline, NBC News reported.
"We are starting to see dead fish. We are starting to see animals like crabs covered in oil, we are starting to see seabirds covered in oil, including some which could not be rescued," said Vikash Tatayah, conservation director at Mauritius Wildlife Foundation, according to The Weather Channel.
While the Mauritian authorities have asked residents to leave the clean-up to officials, locals have organized to help.
"People have realized that they need to take things into their hands. We are here to protect our fauna and flora," environmental activist Ashok Subron said in an AFP story.
Reuters reported that sugar cane leaves, plastic bottles and human hair donated by locals are being sewn into makeshift booms.
Human hair absorbs oil, but not water, so scientists have long suggested it as a material to contain oil spills, Gizmodo reported. Mauritians are currently collecting as much human hair as possible to contribute to the booms, which consist of tubes and nets that float on the water to trap the oil.

There are trillions of microplastics in the ocean — they bob on the surface, float through the water column, and accumulate in clusters on the seafloor. With plastic being so ubiquitous, it's inevitable that marine organisms, such as sharks, will ingest them.
Polyproylene fibers found in one of the sampled sharks. Kristian Parton
Spiny dogfish. NOAA / Wikimedia Commons<p>"There appear to be two routes for these particles to end up in the sharks," Parton said. "The first through their food source [such as] crustaceans. Their prey may already contain these fibers, and consequently it's passed to the shark through bioaccumulation up the food chain. The second pathway is direct ingestion from the sediment. As these sharks feed, they'll often suck up sediment into their mouths, some of this is expelled straight away, although some is swallowed, therefore fibers and particles that may have sunk down into the seabed may be directly ingested from the surrounding sediment as these sharks feed."</p><p>Some sharks only contained a few plastic particles, but others contained dozens. The larger the shark, the more plastic was in it, the findings suggested. The highest number of microplastics was found in an individual bull huss, which had 154 polypropylene fibers inside its stomach and intestines.</p><p>"It's perhaps likely this individual shark had swallowed a larger piece of fishing rope/netting and this has broken down during digestive processes within the shark, and also broken down into smaller pieces during our analysis," Parton said.</p>
Lesser-spotted dogfish caught as bycatch. Kristian Parton<p>While this study only examined the stomach and digestive tracts of demersal sharks, Parton says it's possible that plastic would be present in other parts of the sharks' bodies, such as the liver and muscle tissue. However, more research would be needed to prove this.</p><p>At the moment, there is also limited understanding of how microplastic ingestion would impact a shark's health, although microplastics are known to negatively influence feeding behavior, development, reproduction and life span of zooplankton and crustaceans.</p><p>"If we can show that these fibers contain inorganic pollutants attached to them, then that could have real consequences for these shark species at a cellular level, impacting various internal body systems," Parton said.</p>
Parton in the lab. Kristian Parton<p>This new study demonstrates how pervasive and destructive plastic pollution can be in the marine environment, according to Will McCallum, head of oceans for Greenpeace U.K.</p><p>"Our addiction to plastics combined with the lack of mechanisms to protect our oceans is suffocating marine life," McCallum said in a statement. "Sharks sit on top of the marine food web and play a vital role in ocean ecosystems. Yet, they are completely exposed to pollutants and other human impactful activities. We need to stop producing so much plastic and create a network of ocean sanctuaries to give wildlife space to recover. The ocean is not our dump, marine life deserves better than plastic."</p>

After a Japanese-owned oil tanker struck a reef off Mauritius on July 25, a prolonged period of inaction is threatening to become an ecological disaster.

How to Tackle Oil Spills<p>The method for tackling oil spills depends on several factors, including the type and amount of oil in question, location and weather conditions.</p><p>"Once the oil comes to shore, the more intensive the cleaning technique. You can risk causing further damage," said Nicky Cariglia, an independent consultant at Marittima, who specializes in marine pollution. </p><p>"If you wanted to remove all traces of oil, the techniques available become increasingly aggressive the less oil that remains. In mangroves, you would have the added risk of causing damage by trampling," Cariglia told DW. Highly sensitive mangrove ecosystems line the Mauritius east coast that is threatened by the current spill.</p><p>Because oil normally has a lower density than water, it floats on the surface of the ocean. This means that for clean-up action to be most effective, it should happen very quickly after a spill, before the oil disperses. </p>
