Why is sand listed as an ingredient in my potato chips?
|
view preview
One advantage of being a science major is knowing fancy scientific words for everyday things. Since my teenage years, I developed the habit of reading the ingredients list before purchasing any packaged food item. Recently while searching for a snack at the store, I stumbled upon the potato chips aisle (admittedly, salty, crunchy snacks have always been a weakness of mine). Given how expensive everything has gotten lately, the more affordable budget brands peaked my interest. After quickly glancing over the ingredients of one bag, I noticed that "silicon dioxide" was listed at the end; in fact, it was a common ingredient in that particular brand's entire line of products! Knowing that silicon dioxide is the main component of beach sand, my ...

Who needs supplements when you have kiwis?
|
view preview
Researchers from University of Otago have found that a natural fruit source of vitamin C – kiwifruit – is vastly superior to a purified supplement form. The researchers are studying kiwifruit as a source of dietary vitamin C and found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplement form. The study was recently published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research. ...

What do chiropractors do?
|
view preview
Chiropractic medicine is an approach that is derived from the Greek roots " cheir," meaning hand, and " praxis," meaning practice, and was formulated by the founder of chiropractic, Daniel David Palmer (originally of Canada), to mean " done by hand." The emphasis in chiropractic is on the use of physical manipulation or adjustments to correct misalignment of the spinal vertebrae and other musculoskeletal joints to improve the function of the related organs and musculature. The main treatments used by chiropractic physicians are adjustments, or physical manipulation of the musculoskeletal system. Chiropractors also use heat and/or cold therapy, immobilization (with splints, for example), hydrotherapy, ultrasound, and massage. Chiropractic treatme ...

Watch these white blood cells destroy this roundworm
|
view preview
White bloods cells, known scientifically as leukocytes, are immune system cells that fight infect. The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. Sometimes our bodies encounter pathogens like bacteria, or in this case a parasitic worm. Roundworms, or nematodes, are parasites that can infect people by living and feeding in the intestines. There are different kinds of worms that can cause infection, and they can range in length from 1 millimeter to 1 meter. Luckily, this worm was no challenge for these hungry white blood cells. ...

Try dates, not honey
|
view preview
While they are super sweet, syrup made from this ancient fruit has antibacterial compounds that are more effective than honey. In case you've never had it or seen it before, dates are a thick, dark brown, and super-sweet fruit used in Middle Eastern cuisine. New research suggests that date syrup contains chemical compounds that help ward off a number of bacterial infections, including those caused by Staphylococcus aureus and Escherichia coli. This was discovered after scientists inhibited the growth of these pathogens for about six hours, which researchers say is faster than manuka honey - a honey known for its antibacterial and wound healing properties. ...

Tips to keeping your teeth white
|
view preview
Whitening treatments do not permanently whiten teeth. If you expose your teeth to foods and beverages that cause staining you may see the whiteness start to fade in as little as one month after treatment. Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening treatment or touch-up is needed. You worked hard to get your teeth white. Here are some tips to help maintain your pearly whites. - Avoid the consumption of or exposure to products that stain your teeth, such as coffee, tea, and red wine. If you do choose to consume beverages that stain, consider using a straw so that the liquid bypasses your front teeth.
- Brush or rinse immediately after consuming stain-causing beverages or foods.

This peanut butter is a health hazard
|
view preview
I was shopping around in Michigan a few weeks ago when I stumbled upon this product proudly made by the Velvet Peanut Butter Company. I was appalled when I read that it's made from Fully Hydrogenated Vegetable Oil, while the trans-fat count is at zero grams - a very misleading claim. This product is literally poisonous for human consumption, yet it is prepared for young children and people of lower socioeconomic status, given its low price tag. Hydrogenated oil is scientifically known to increase LDL 'bad' cholesterol and lower HDL 'good' cholesterol, thereby leading to heart disease and cancer. It should be against the law to feed it to kids. In the United States, labelling a product trans-fat free doesn't necessarily mean it doesn't conta ...

The importance of phytochemicals
|
view preview
Phytochemicals are compounds in foods found in plants that are thought to be beneficial to health. More than 5000 different types have been identified, and several studies have linked their intake to reduced risk for cardiovascular disease, cancer, diabetes, Alzheimer’s, cataracts, and age-related decline. While they may be beneficial, they are not considered nutrients (substances necessary to sustain life), thus no daily recommended intakes have been established. A list of five popular phytochemical families are listed below, along with their health claims and food source. Carotenoids:Includes: Alpha-carotene, beta-carotene, lutein, lycopene, zeaxanthin, etc. Health Claims: Diets with foods rich in these phytochemicals may reduce the risk of ...

Running reduces tumor size in mice by 50%
|
view preview
According to a new study published in Cell Metabolism, mice who spent their free time on a running wheel were better able to shrink tumors (a 50 percent reduction in tumor size) compared to their less active counterparts. Researchers found that the surge of adrenaline ( epinephrine) that comes with a high-intensity workout helped to move cancer-killing immune (NK) cells toward lung, liver, or skin tumors implanted into the mice. While the research is hopeful for patients looking for inexpensive ways to manage their cancer, more needs to be learned about the effects of exercise on metastasis and longevity, as well as if the observations hold true in humans. Scientists also wants to explore the combined impact of anti-cancer treatments and ex ...

Living without a heart
|
view preview
Stan Larkin (pictured on the right), who's now 25, was diagnosed with familial cardiomyopathy. This form of disease results in the heart having difficulty pumping enough blood through the body. Faced with a lack of compatible heart donors, Stan underwent an operation in 2014 to remove his failing heart and replace it with an external total artificial heart, dubbed the Freedom portable driver. This battery-powered device uses compressed air to pump blood around the body in the same way a heart does, and as the name suggests, it is portable and only weighs 6 kilograms (13 pounds). The device does an incredible job at keeping the patient in a healthy condition while a donor heart becomes available, but it isn’t considered a long-term option. ...

It's sore throat season, why does my mucus have red spots?
|
view preview
It's that time of year again when the weather starts to change, and we're more prone to getting sick. One such symptom that accompanies these seasonal illnesses is a sore throat. Sore throats not only feel like you've swallowed sandpaper, but they are also accompanied by coughing, congestion, and the production of mucus, sometimes with spots of blood. Firstly, mucus plays a crucial role in our respiratory system. It's a slippery, gel-like substance produced by the mucous membranes lining various parts of our body, including the respiratory tract. This viscous fluid serves as a protective barrier against invaders such as pathogens and irritants. It also helps keep these surfaces moist, allowing for proper functioning and efficient air exchang ...
