  • Can Too Much Caffeine Kill You? Here’s What You Should Know

    Can Too Much Caffeine Kill You? Here’s What You Should Know

    Recent news reports of a teen who overdosed on caffeine and, unfortunately, died. Here’s what you should know.

    Recent events show that it seems even your coffee can be fatal. A high school 16-year old was pronounced dead on April 27, 2017 a few hours after he blacked out in class. The official cause of death was stated as probably a fatal arrhythmia or other cardiac event.

    His classmates informed the medical coroner that the teen drank a McDonald’s cafe latte, a large Mountain Dew, and a 16-ounce energy drink all within two hours. All three drinks are teeming with caffeine. The medical coroner theorized that the sudden burst of caffeine to his system disrupted his heart so much that it ultimately lead to the teen’s death.

    The American Academy of Pediatrics warns that teens and children shouldn’t ingest caffeine at all. The FDA recommends that adults limit their caffeine intake to 400 milligrams daily.

    If You Don’t Overdo It, Caffeine Is Actually Healthy for You

    But drinking caffeinated drinks can actually be very healthy as long as you don’t overdo it. For example, research shows that drinking coffee during key times can enhance your subsequent activities:

    • Drinking coffee before exercising boosts your metabolism and blood flow to your muscles, which helps you work out for longer without feeling exhausted. It also lowers muscle pain afterward.
    • Regularly drinking coffee can help protect your liver from cirrhosis caused by drinking alcohol. It also helps prevent you from developing diabetes, neurodegenerative disorders, cardiovascular disease, and cancer.
    • Drinking coffee 24 hours before taking a written test helps you perform better because it boosts your memory.



    These researchers recommend drinking only up to five cups of coffee daily. Drinking more than that can undo these health benefits. Ready-made coffee you buy at restaurants usually come loaded with unhealthy cremes, artificial chemicals, sugar, and other unfavorable ingredients. It’s best to brew your own coffee using pure coffee beans without adding milk or sugar.

    Healthier Naturally Caffeinated Beverages

    If you want to maximize caffeine’s holistic benefits without risking a fatal overdose, you can choose these better beverage options that come with a slew of other health benefits:

    Green or white tea. Green and white teas have higher cancer-fighting polyphenol and catechin content than other teas. They’ve also been found to boost your immunity and cardiovascular health. Their high antioxidant content also helps slow aging and lengthens your life. Of course, they’re both caffeine-rich, which means you also get all the benefits of caffeine when drinking either tea.

    Hot cocoa. Hot cocoa made from dark chocolate or pure cocoa has a high caffeine content. They’re also low-calorie and filled with antioxidants. Its flavanols have been found to boost your cognitive abilities for up to three hours. Eating or drinking cocoa regularly also protects your heart and helps you lose weight. Enjoying hot cocoa regularly means you get all these benefits and more, plus all the benefits that come with caffeine too!

    Caffeine can heal and protect your body, but don’t chug down too many caffeinated drinks within the span of a couple of hours because that can lead to cardiac complications. If you have children, it’s probably impossible to keep them away from caffeinated beverages because most popular sodas are teeming with caffeine. But do keep in mind that experts recommend that children and teens don’t drink caffeine, and that adults have a daily limit of 400 milligrams.

  • Scientists Discover That Which City You Live in Can Increase Your Risk for Developing Cancer

    Scientists Discover That Which City You Live in Can Increase Your Risk for Developing Cancer

    A review of cancer statistics from extensive sources reveals that places with poorer environmental quality can put you at greater risk for developing cancer.

    The urban life attracts many with prospects of higher incomes, busier lives, cutting-edge technology and fashion, and a more diverse, fun environment. But experts are finding that you may be trading your health for a better lifestyle by moving into busy cities. They found that poor quality environments can increase your risk for cancer.

    Researchers went through numerous statistics from many governmental health agencies, including the U.S. National Cancer Institute and the EPA, and tried to find a correlation between cancer incidence and air quality, transportation and housing safety, water quality, pesticide exposure and contamination, and exposure to crime. They found that places which are lower overall in these environmental qualities have higher incidences of cancer.

    They found that prostate and breast cancer rates were the most sensitive to environmental quality. That means that living in an area that exposes you to a lower quality environment puts you at greater risk for these two cancers.

    Sadly, they also found that the more urbanized a place is, the lower the environmental quality tends to be. Highly urbanized places, like major cities, were found to have the lowest environmental quality. But even almost unpopulated rural areas can have a lower quality environment compared with a more populated suburban area if these rural areas have more pesticide exposure from farming or some other outstanding lower environmental factor.

    How to Protect Yourself From Environmental Cancer Risks

    But often it’s not possible to choose the environment you live in. Financial situations may force you to move to more polluted cities. Also, you shouldn’t give up your life goals for better environmental quality because the increased cancer risks aren’t as significant as something on the level of smoking cigarettes or using a tanning bed. While it isn’t possible to avoid all increased risks of developing cancer coming from your environment, there are many proactive things you can do to lower these risks significantly:




    1. Test Your Water

    Water quality is one of the environmental factors used in the review. Many cities across the U.S. have outdated irrigation systems that leak lead and other pollutants into their tap water. If you remember the Flint, Michigan lead contamination crisis, then you should know that Providence, Rhode Island children recently were found to have levels of lead in their bodies that are 300 percent over dangerous levels. Recent tests also found that some homes’ tap water in Portland contain lead levels that exceed EPA’s health hazard limits.

    Besides increasing your risk for cancer, continuing to introduce contaminated water into your system has been found to lower your cognition and overall brain power. The impact is so significant that children who were exposed to lead in their drinking water ended up with such lower IQ and cognitive abilities that their socioeconomic status was lower than their parents even at age 38!

    Given these findings on lead-contaminated cities and this new review linking environmental quality and cancer risk, it’s not a coincidence that Portland, Flint, and Providence are both highly urbanized places and have notorious lead water levels. If you live in a highly or somewhat urbanized location, there’s a chance your tap water may be contaminated too.

    But no matter where you live, it’s best if you run your own tests on your tap water to see if it’s safe for consumption. Local government agencies only test a few homes’ tap water and assume nearby homes have similar results. That means you shouldn’t assume your home’s tap water has been tested and officially approved as safe for drinking.

    2. Avoid Outdoor Air Pollution and Control Indoor Air Pollution

    It’s difficult to control the air pollution you’re exposed to if you’re living in a major city. But there’s still a few things you can do to lessen your exposure.

    Try to leave before rush hours. Commuting when there’s less traffic means you’ll likely be exposed to less smog. Try to pick routes with less traffic and fewer smoke-spewing buildings (like restaurants or industrial areas). Doing these two things will greatly reduce your exposure to outdoor air pollution.

    When at home, you can minimize indoor air pollution by vacuuming more often to reduce the dust you breathe in. Don’t use scented candles or artificial air fresheners because there’s evidence they vaporize chemicals that can disrupt your endocrine system and cause cancer. Instead, use a doctor-recommended air purifier that cleans the air of odor-causing particles and dust. Remember to change your HVAC filters and air purifier filters regularly to maximize their air filtration.

    You should also cultivate houseplants, which boost your indoor oxygen supply and naturally remove harmful vaporized pollutants (like benzene and formaldehyde) emitted from electronics. These are vital for your home office, which may have higher levels of these cancer-causing pollutants coming from your printer and computers. But formaldehyde and some other dangerous pollutants are also released by a few paints, varnishes, paper products, foam insulation, and other fixtures that came with your urban rental. Thankfully, household plants have been shown to lower formaldehyde levels in the air by about 600 percent. These researchers found that ferns are the best houseplants for removing formaldehyde from indoor air.

    3. Wash or Boil Your Produce

    Pesticide exposure is another environmental factor the review took into consideration. You can lessen pesticide exposure from the air by wearing long-sleeved tops and pants. Wearing clothes that cover more of your body means less pesticides can make contact with your skin and get absorbed into your body.




    But you must also wash your fruits and vegetables to remove more pesticide residues. The National Pesticide Information Center advises to wash and rub your produce by hand under a strainer to get more pesticide residues out. If you’re eating the produce raw, then you should also wash with a diluted solution of vinegar to kill harmful microbes.

    Research shows that boiling your produce ultimately removes the most pesticide residues. They found that boiling fruits and vegetables removes between 50 to 100 percent of pesticide residues, whereas simply washing and rubbing produce only removes between 20 to 89 percent.

    Removing as much pesticides from your food as possible helps lessen your overall pesticide exposure.

    4. Be Vigilant About Your Housing and Transportation

    Not everyone follows the law, and surely you’ve gone over the speed limit at least once when driving. The same applies to landlords and transportation companies. Housing and transportation safety is another environmental factor that can increase your risk for developing cancer. Make sure where you’re staying and what you’re riding are currently following all codes and regulations.

    Also make sure your home isn’t built with asbestos, lead-based paint, and other health hazards. If during your checks you find that your housing or transportation might be exposing you to unnecessary harmful pollutants, then you should choose different providers to avoid these potential increased cancer risks.

    You can’t avoid all the health risks your environment poses. But now that you’re aware of certain aspects of your environmental that can contribute to causing cancer, you can proactively lessen their impact on your body. Although living in an ideal, safe place would be best, you shouldn’t give up on your ambitions by actively avoiding highly urbanized places. Strive for your goals and protect your health along the way!

  • 3 Reasons Why Doctors Might Say You Should Drink Four Cups of Coffee Everyday

    3 Reasons Why Doctors Might Say You Should Drink Four Cups of Coffee Everyday

    It’s 5 A.M. and you’re reluctantly getting up to do your morning exercises before you have to prepare breakfast and drop the kids off at school. Believe it or not, having a cup or two of coffee now instead of during breakfast or before heading out to work can improve your workout. In fact, having another two cups of coffee throughout the day, like during lunch, protects you from chronic illnesses like cancer! Sounds crazy? Well, scientists don’t think so.

    Drinking coffee gets you more kick from your workouts.

    Drinking coffee before working out increases your metabolism while you exercise, according to a study published in the International Journal of Sport Nutrition and Exercise Metabolism. They found that you’ll burn 15 percent more calories if you drink 4.5 milligrams of caffeine per kilogram of your weight. If you weigh 110 pounds, that’s around 224 milligrams of caffeine or 2.5 cups of coffee.

    Research also shows that drinking regular coffee increases your blood flow by 30 percent, which allows your muscles more oxygen during your workout. They also found that drinking two or three cups of coffee an hour prior to a 30-minute high-intensity workout reduces muscle pain. That means drinking coffee also helps you endure longer during strength or endurance workouts.

    If you do endurance training you’re most likely doing intense workouts everyday. Thus, your glycogen stores must be replenished quickly. Muscles store and use glycogen to give you power and endurance during exercise. If your muscles’ glycogen stores are high you can last longer and deliver more power. Fortunately, drinking coffee with your post-workout meal helps with that! Research shows that a diet of caffeine and carbohydrates increases your muscle glycogen by 66 percent four hours after an intense, glycogen-depleting workout.

    Drinking coffee also protects your muscles in the long term. Studies find that regularly consuming coffee offsets natural muscle strength loss due to aging. This isn’t limited to the muscles you actively tone during your workouts – the protective effects were observed in the diaphragm too, protecting your body’s ability to breathe as you get older. Researchers believe from these findings that your coffee habit may preserve your overall fitness and even decrease your risk for age-related injuries too.

    Drinking coffee helps prevent chronic diseases.

    If you party hard on Fridays after work with your friends, remember your cup of Java! Research by the University of Southampton finds that drinking four cups of coffee daily reduces your risk of developing cirrhosis from long-term alcohol consumption by 65 percent.

    These daily four cups of coffee also protect you from other chronic diseases as well. Research by Harvard University finds that drinking one to five cups of regular or decaf coffee everyday helps protect you from cardiovascular disease, stroke, neurodegenerative disorders like Parkinson’s and Alzheimer’s, and diabetes mellitus due to coffee’s bioactive compounds which protect against blood-brain barrier blockage and reduce systematic inflammation and insulin resistance. However, drinking more than five cups reverses these health benefits.

    Furthermore, a study published in the Journal of Neurology and Psychiatry finds that drinking at least four cups of coffee everyday reduces your risk for developing multiple sclerosis by 26 to 31 percent. There seem to be compounds in coffee that have neuroprotective effects.

    Drinking four cups of coffee everyday helps prevent cancer too. Another Harvard study found that colon cancer patients in remission who drank four or more cups of coffee had a 42 percent decreased risk of cancer recurrence and a 34 percent decrease in overall mortality (including cancer-caused mortality).

    Ultimately, researchers found that drinking coffee reduces overall mortality by 15 percent.

    Late night studying with coffee to keep you awake is actually good for you.

    Drinking coffee while you study improves your memory. A John Hopkins study found that consuming caffeine enhances your memory for 24 hours. Caffeinated participants scored higher than non-caffeinated participants when shown images and asked to recall them. Remember that next time you’re studying for grad finals or working late finishing paperwork!

    If you chug a lot of coffee to boost your energy don’t be ashamed – it’s actually good for you! Drinking coffee before and after exercising enhances your performance and supports your muscles’ recovery. Coffee is also holistically healthy, helping prevent a wide range of diseases. Coffee also helps you cram for exams! But to be on the safe side, drink only four cups of coffee daily – you don’t want to reverse these health benefits.

  • Cellphones Have Been Officially Recognized as Causing Brain Cancer: Here Are Some Ways to Keep Yourself Safe

    Cellphones Have Been Officially Recognized as Causing Brain Cancer: Here Are Some Ways to Keep Yourself Safe

    In Italy, a court made a decision that might prove medically noteworthy. They found that a man’s brain tumor was caused by cellphone usage. It’s difficult not to use a cellphone in this modern era, so here are ways to help lower your risks for developing cancer.

    Cellphone Use Legally Linked With Causing Brain Cancer

    Robert Romero was required to use his cellphone for three hours daily for 15 years while working for Telecom Italia. He developed a brain tumor and the court found that it was caused by his cellphone usage.

    He was awarded about $7,500 per year in damages for the rest of his life. It’s a weird monetary award from an American perspective because it could be on the low end of the spectrum or on the very high end, depending on whether he dies of old age or gets hit by a car the very next day.

    The legal decision is a silent opening of a floodgate. One consumer welfare group has already started the flood by initiating a class action suit to force all cellphone companies to add a warning label about the risks of brain cancer and cellphone usage.

    But Does Using Your Cellphone Cause Brain Cancer?

    Everyone uses a cellphone, especially now that smartphones are becoming more common and accessible to all ages. Smartphones are becoming a necessity because of their internet capabilities. Many stores have QR codes placed on their wares, which gives shoppers with smartphones a price advantage over those who don’t. But is all this cellphone usage putting everyone at risk for brain cancer?

    The National Institutes of Health conclude that cellphones don’t cause brain cancer, in general. They say that cellphones emit radiofrequency energy that doesn’t damage or change DNA, but does cause nearby living tissue to heat up. After reviewing numerous studies, they found no statistically significant increased risk of brain cancer with normal cellphone usage.

    But they did mention that in more than one study, brain cancer was more prevalent in heavy cellphone users, like Robert Romero. But they haven’t cited any studies that focused on heavy cellphone usage only.

    In a more recent study with rats, heavy radiofrequency energy exposure has been found to cause higher rates of brain and heart tumors. But the study is small, and further research must be done for experts to make a definite conclusion.




    Cellphones Lower Male Fertility

    What researchers are sure of is that being near cellphones or talking on a cellphone lowers male fertility. They found that men who talked for longer than an hour a day on their cellphone or had their cellphones close to their groins for a significant period of time experienced lower sperm counts and lower semen quality.

    What’s the Takeaway?

    It seems like the human and rat studies point to one unofficial conclusion: Using your cellphone for longer than normal can lead to brain cancer and a decrease in male fertility. The Italian courts state that an hour a day is normal cellphone usage.

    To be safe and lower your risk for cancer and decreased fertility, don’t use or be near your cellphone for longer than an hour a day. If you need to talk on your cellphone for longer than that, use a headset and keep your cellphone a safe distance away, like on the table or a seat next to you.

    To lower your exposure to your cellphone’s radiofrequency energy, don’t keep your cellphone in your pockets, but store them in a carry-on bag. Also never sleep with your cellphone close to your body – keep it on a nearby table.

    How to Naturally Lower Your Risk for Developing Cancer

    It’s highly unpractical for you to avoid your cellphone on a daily basis, especially if you’re a corporate person. But there are healthy ways you can help protect yourself from developing cancer:

    Try to avoid red meat. Harvard finds that one additional serving of unprocessed red meat increases your risk for total mortality, including cancer, by 13 percent. If it’s processed meat, the increased risk is 20 percent!

    Eat vegetables with every meal. Vegetables, especially cruciferous vegetables, are high in antioxidants. These protective compounds circulate through your body once absorbed and neutralize toxins, free radicals, and other cancer-causing pollutants in your system. As a bonus, they also help slow signs of aging.

    Exercise more. Researchers found that exercising more than 150 minutes every week lowers your risk for 17 different types of cancer, including lung, breast, and brain cancer, by at least 20 percent. But you need to be exercising at a moderate intensity level – leisurely walks won’t do, but leisurely jogs fit the bill.

    Incorporating these cancer-protective things into your regular regimen can help offset the increased cancer risk from using your cellphone daily.

  • Can This Blood Test Detect Cancer a Year Earlier Than Normal Tests?

    Can This Blood Test Detect Cancer a Year Earlier Than Normal Tests?

    Scientists invented a new blood test that can detect whether a cancer is recurring a whole year before any current mainstream tests can detect. In general, blood tests are non-invasive, cheaper, and easier to get done. This new method could prove to be an ideal first line of defense for cancer patients.

    If you’ve survived a form of cancer, this new research is great news for you! Researchers have invented a new blood test that can detect your cancer from recurring 365 days before X-rays, CT scans, and other current mainstream diagnostics.

    Depending on your form of cancer, recurrence can be a little or a significant worry. These researchers originally developed this new recurrence detection method especially for lung cancer patients in remission because lung cancer has about a 50 percent chance of recurring.

    They took samples from tumors removed from surgery and created a genetic profile from the cancer cells’ mutated DNA. They then drew the patient’s blood each month post-surgery and tested it for any traces of the cancer cells’ genetic profile. They found that if the cancer starts recurring, its genetic profile is present and detectable in the blood one year before the recurring cancer can be detected using current methods.

    If first caught early via this new blood test, the recurring cancer cluster is still tiny at 0.3 cubic millimeters.

    The great news is that they found this new blood test works for all recurring cancers, not just lung cancer – the key is that doctors need a sample of your cancer cells to make a genetic profile they can keep checking your blood for. But the blood test is not error-free – in the study, 13 out of 14 patients’ recurrence were detected with the blood test. That means one patient didn’t luck out and the blood test didn’t catch his starting recurrence.

    It also doesn’t work on people who’ve never had cancer. Its current usage is limited to detecting cancer recurrence in patients in remission.

    Sampling for the Blood Test Also Gives Hints on Risk of Recurrence

    While creating genetic profiles from tumors from many patients, the researchers happened upon another good find. They found that the patients who ended up with a recurrence usually also have cancer cells with more genetic instability. They concluded that recurrence is more likely if a cancer cells’ chromosomes are more favorable toward shuffling or translocating their genes.

    The researchers hope to use this supplementary finding to create drugs that stabilize cancer cells’ genetics in hopes of slowing tumor growth and overall cancer progression.

    In the meantime, patients in remission whose cancer cells’ genetic profiles exhibit genetic instability are more closely monitored for the possibility of recurrence.

    Although this new research can’t currently help diagnose new cancers, it is a significant advancement in overall cancer research. With this new blood test, patients in remission can be diagnosed and treated if a recurrence starts budding before these patients even experience any symptoms. In the grand scheme, it will certainly save many more lives from cancer.

  • Hate Fish? No Problem, Eat a Cup of Walnuts Instead!

    Hate Fish? No Problem, Eat a Cup of Walnuts Instead!

    If you’re trying out a vegetarian diet to lose weight, you’re probably worried about meeting your daily protein requirements. Nut milks are a popular protein source for vegetarians. However, walnuts stand out amongst other nuts due to their omega-3 fatty acid content.

    Omega-3 fatty acids raise your good cholesterol and lower your bad cholesterol. They also decrease your risk for cardiovascular disease by 40 percent and lower your risk for cancer. These essential fats also prevent Alzheimer’s, arthritis, and retinal degeneration. For children, omega-3 fatty acids significantly support eye and brain development; 9-month-old infants experienced significant increases in problem-solving skills subsequent to being fed a diet high in omega-3 fatty acids.

    Seafood is the predominant dietary source for omega-3 fatty acids. Hence, vegetarians and people who hate eating fish are at risk of lacking their daily recommended dose of these essential fats. Fortunately, just one cup of walnuts bestows approximately 10 grams of omega-3 fatty acids, which is greater than the recommended daily dose.

    Aside from omega-3 fatty acids, walnuts also contain antioxidants and other nutrients. Its antioxidants include tellimagrandin, morin, and juglone, which have been shown to prevent liver damage and inhibit atherosclerosis. They bind well to lipoproteins, so they improve your body’s fat efficiency without causing weight gain, and also reduce any inflammation.

    Walnuts also contain ellagic acid, which has antibiotic and antiviral properties. Ellagic acid has been recognized by Memorial Sloan-Kettering Cancer Center to have anticarcinogenic properties as well. In fact, studies show that mice that have had their diets supplemented with walnuts experienced smaller, slower-growing prostrate tumors, with an overall 30 to 40 percent decrease in prostrate cancer. There’s also evidence that eating walnuts reduces breast cancer risk as well.

    Walnuts’ nutrients also have weight-loss properties. A study published in the European Journal of Clinical Nutrition showed that despite consuming a daily diet containing 2,000 calories, subjects experienced a drop in blood sugar levels and weight loss when walnuts were supplemented into their diet.




    Finally, eating walnuts improves your sexual and reproductive health. American guys who consumed typical Western diets experienced improved sperm vitality, motility, morphology, and overall quality when 75 grams of walnuts were added to their diet.

    When choosing walnuts at the store try to purchase organic and raw walnuts as opposed to irradiated or pasteurized. Also, 90 percent of walnuts’ aforementioned antioxidants are contained in the walnuts’ skin. Hence, despite the skin’s bitter taste, make sure to eat it!

    Eating a cup of walnuts each day can be hard on your teeth and less than enjoyable. But you can always blend your walnuts into a smooth nut milk.

    Vegetarians and people who hate seafood are at risk of not getting enough omega-3 fatty acids. In addition to being a great source of these essential fatty acids, walnuts promote weight loss and healthier sperm, and have anticarcinogenic and antibiotic properties as well. Don’t forget to consume the skin, or you’ll only be getting 10 percent of these benefits.
