One in 20 North Americans can expect to develop colon cancer, with more than 100,000 new cases each year. A recent review of 80 studies found that most cases of colon cancer are linked to poor lifestyle choices.
Lack of vitamin D can cause weak bones that break easily, bone pain, and muscle weakness, and may increase risk for diabetes, high blood pressure, certain cancers, nerve damage and autoimmune conditions such as multiple sclerosis. However, taking very high doses (>3000 IU/day) of vitamin D can harm you.
Two recent studies show that non-ionizing radiation from cell phones may be associated with impaired ability to recall images, but not words, in teenagers; and at high levels, can increase brain and heart tumors in rats. Most studies on cell phone use have not shown increased cancer risk or memory loss.
The only way that scientists are going to end this current pandemic is to develop vaccines and immunize enough people to reach immunity in about 40 percent of the population from the vaccines or by having been infected with the disease.
If you belch or have burning in your stomach or chest, particularly when your stomach is empty, you probably have either an infection, a tumor, or a condition called GERD (reflux or regurgitation). Infection with bacteria such as helicobacter pylori is by far the most common cause.
Stem cell clinics have sprung up in most states, but are most abundant in Arizona, California, Colorado, Florida, New York and Texas. Last year the FDA sent warning letters to clinics in California, Florida and New York for illegally using stem cells from people's fat tissue to treat conditions such as Parkinson's disease.
Many people are worried that they may not receive their second dose of the vaccine on schedule because of delayed deliveries of the vaccine, or because of suggestions that the scheduled second doses of the vaccines should be given as a first dose to others so that more people can be immunized.
Skin responds to friction and pressure by thickening. This is helpful until the skin becomes so thick it actually hurts. Skin that thickens without a core is called callus. They usually form under the foot. Corns are thick spots of skin with a deep, central core. They usually form on the toes.
A review of 45 prospective studies found that risk for suffering colon cancer is increased by drinking alcohol and eating red meat, and decreased by eating more fiber and yogurt. More than 1.3 million North Americans have had colorectal cancer, a disease associated with lifestyle factors that cause bad bacteria to thrive in your colon.
As of 3/27/20, we have no drugs that have been proven to be effective for shortening the course of COVID-19 infections. Several possible drugs are currently being tested in the midst of the massive outbreak in New York City.
Millions of North Americans take zinc lozenges to treat their colds. A study in the Archives of Internal Medicine showed that they neither shorten the cold nor lessen its symptoms. Another study from the University of Virginia showed that zinc nasal sprays do not prevent or treat the common cold.
One in nine North Americans over age 65 will develop dementia, a progressive brain disorder that interferes with normal daily living and is marked by memory loss, personality changes and impaired reasoning). Aging is the major risk factor for dementia, but forgetfulness among seniors does not necessarily mean the person is headed for dementia.
A diet that is high in either red meat or sugar, or both, increases the growth in the colon of bacteria called Fusobacterium nucleatum that appears to suppress a person's immunity to increase the growth of cancer cells in the colon.
Colds and pneumonia are caused by infection. You do not pick up infections from cold weather, you get germs from other people who sneeze or cough in your face or transmit germs with their hands to objects that you touch.
More than 80 million CT scans are done in the U.S. each year to help diagnose many medical conditions. In 2007, the National Cancer Institute predicted that 29,000 future cancer cases could be linked to the CT scans performed in the U.S. in that year alone, and doctors have ordered more CT scans every year since then.
The Environmental Working Group (EWG) released its 2022 annual Guide to Sunscreens, which found that 75 percent of more than 1,850 sunscreen products evaluated either offered poor skin protection from the sun, or contain ingredients that may harm your health or increase your skin’s sensitivity to the sun’s harmful rays, Only 25 percent of the products met EWG's standards for adequate protection and did not contain harmful ingredients such as oxybenzone that is an endocrine disrupter.
More than 1.3 million North Americans have had colorectal cancer, a disease associated with lifestyle factors that encourage cancer-causing bacteria to thrive in your colon. A new study shows that 992 people who were already diagnosed with colon cancer that had spread beyond the colon, who changed to a healthier diet and exercise program, had a 42 percent lower risk of dying over the next seven years compared to those who did not change their lifestyles.
An international team of research scientists and practicing doctors from Canada, the United States and Australia report that the bacterium that causes Lyme disease is found in 100 percent of the vaginal secretions of women and half of the semen of men suffering from Lyme disease.
We have no drugs yet proven to prevent or treat COVID-19, although some drugs appear promising, as do transfusions of blood donated by people who have recovered and are now immune. The virus is spread from one person to another; it has not been shown to be spread from animals or food.
About 22 percent of North Americans ages 85-89 and 33 percent of those over 90 suffer some degree of dementia. A study from the Chicago Health and Aging Project, which followed 2449 men and women over age 65, suggests that there is a lot that you can do to help protect yourself from dementia. The healthful lifestyle factors tracked in this study included diet, physical activity, cognitive activity, not smoking, and avoiding or limiting alcohol
In August 2015, the world learned that former U.S. president Jimmy Carter’s melanoma skin cancer had spread to his liver and his brain. Patients with melanoma that had spread through their bodies were expected to die from their disease, but doctors radiated Carter's tumors and then gave him Keytruda, a check point inhibitor. Three months later, there was no evidence of cancer in his 91-year old body.
Researchers in Finland followed 3,596 children (3-18) for 31 years to see whether cardiovascular risk factors in childhood and adolescence were associated with cognitive performance later in life. Cognitive testing was performed in 2,026 of the participants at 34-49 years of age, and the researchers found that early heart attack risk factors were also major risk factors for reduced mental function.
A study from the Karolinska Institutet in Sweden shows that repeated bouts of exercise slow the growth of, and help to prevent recurrences of, cancers. The authors showed, in both mice and humans, that exercising muscles release into the bloodstream chemicals that increase production of CD8+ cells that an individual's own immune system uses to kill cancer cells.
The American Heart Association promotes a list called "Simple 7" as a reminder of the lifestyle habits that can help to prevent dementia and heart attacks. This "Simple 7" list has been used in a 30-year study of 11,561 people (average age 54), with 2234 who developed dementia during the study period.
Vitamin D deficiency increases risk for becoming infected with COVID-19, and for complications and death from the disease. A study of 500 patients showed that those who had low blood levels of hydroxy vitamin D were twice as likely as those with normal levels to develop COVID-19.
People with no symptoms transmit more than half of all cases of COVID-19, according to a model developed by researchers at the Centers for Disease Control and Prevention. This reinforces the importance of following the CDC's basic guidelines: wear a mask, wash your hands, and stay socially distant.
The U.S. Centers for Disease Control and Prevention (CDC) reports that we may need to continue social distancing and hand washing for years to come. The significant reduction in non-COVID-19 respiratory infections this year could decrease the number of people who are immune to other respiratory viruses, and increase the frequency and severity of other respiratory infections in the future.
