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 ...

A sense of control can aid recovery
|
view preview
If emotions can make you sick, if a belief that you will die can kill you (as in voodoo deaths), and if a sugar pill that you believe is a powerful drug can take away your pain, can a belief that you can bring about your own recovery help you to recover?Even with acceptance of the role of emotional factors in both illness and recovery, the assumption has persisted that emotional factors work on an unconscious level, and because of this they are not subject to voluntary control. Most of us still see illness as something that happens to us. Dr. Carl Simonton, chief of radiation at Travis Air Force Base, questioned this assumption. He was impressed by demonstrations that people could learn to control autonomic processes through biofeedback and ...

Try imagining for a second how it'd feel to lose your eyesight. It's almost unimaginable because your vision is perhaps the most valuable tool for survival. This is why we need to constantly protect our eyes and learn what could potentially ail them. Below is a list of five common illnesses that plague the precious eyes of people around the globe. GlaucomaGlaucoma is damage to the optic nerve, often caused by elevated intraocular pressure. It results from excessive production of aqueous humor or diminished ocular fluid outflow. Glaucoma is a leading cause of blindness, secondary to optic nerve damage. As of yet, there is no cure. Everyone is at risk, and there may be no warning signs. It is six to eight times more common in African Americans ...

A meta-analysis of 40 studies concludes that cinnamon can improve memory and cognitive function
|
view preview
A team of researchers at Birjand University of Medical Sciences in Iran recently reviewed several past studies exploring the effects of cinnamon on cognitive functions. Their analysis, outlined in Nutritional Neuroscience, highlights the potential value of cinnamon for preventing or reducing memory or learning impairments. Nakhaee, Kooshki and their colleagues reviewed hundreds of studies stored in several online research databases, including PubMed, Scopus, Google Scholar and Web of Science. They then narrowed down their analysis to 40 of these studies, those that were most pertinent to their topic of interest. Among these 40 studies, 33 were carried out in vivo (i.e., examining real living organisms, such as humans, rodents, or other animal ...

Could dietary salt be the reason for increased incidences of autoimmune diseases?
|
view preview
Researchers at Yale School of Medicine, Harvard Medical School and the Broad Institute have identified a prime suspect in the mystery of an increased incidence of autoimmune diseases in the past few decades—dietary salt. In the paper, researchers showed that salt can induce and worsen pathogenic immune system responses in mice and that the response is regulated by genes already implicated in a variety of autoimmune diseases.

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 ...

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.

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.

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 ...

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. ...

Hand washing in public restrooms, not so common
|
view preview
Bayer Corporation and the Public Health Committee of the American Society for Microbiology sponsored a study of hand washing in public restrooms. Researchers from the survey group hid in stalls or pretended to comb their hair while they observed over 6,000 men and women in five large cities. Their observations revealed that many people prefer a "get up and go" strategy, failing to wash their hands after using the restroom facilities. In New York's Penn Station, for example, only 60% of restroom users washed after relieving themselves. Similar rates were found in other cities: 64% of restroom users washed at a Braves game in Atlanta, 69% washed in San Francisco's Golden Gate Park, 71% used soap and water in a New Orleans casino, and a laudab ...

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 ...

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. ...
