More than 90 percent of North Americans will develop high blood pressure. A new study shows that a diet high in potassium appears to protect teenagers from high blood pressure in adulthood, while a low-salt diet has no effect (JAMA Pediatr, June 2015;169(6):560-568). A high-potassium and low-salt diet is achieved by eating mostly plants,...
A 6.5-year-long study followed 826 people who had been diagnosed with colon cancer that had already spread to their lymph nodes and been treated with chemotherapy and radiation. The researchers found that those who ate at least two one-ounce servings of tree nuts per week gained a 42 percent reduced rate of cancer recurrence and and a 57 percent reduced risk for death during the study period.
A review of the world's literature shows that high-intensity exercise, particularly interval training, causes greater reduction in HbA1c in diabetics than less intense exercise. HbA1c measures cell damage from high blood sugar levels. Many studies show that increasing exercise intensity controls blood sugar in diabetics more effectively than just increasing the duration of exercise.
A study of 14,392 individuals with high blood pressure, followed for 5-10 years, found that those who adopted a healthful lifestyle along with taking medication had a much lower risk for suffering heart attacks and lived significantly longer than those who treated their high blood pressure just with drugs.
Having high blood levels of cholesterol increaes your chances of getting a heart attack, but your blood cholesterol level is influenced far more by how many calories you eat than by how much cholesterol is in the food you eat.
Pain messages are passed along nerves by a neurotransmitter called "substance P." Capsaicin, the component of chili peppers that makes them hot, blocks substance P and the resultant pain. A cream containing .025 percent capsaicin has been shown to block pain in joints, nerves and skin
To function properly, your immunity depends on the tens of trillions of bacteria in your intestines. New cancer treatments rely on gut bacteria to help stimulate the immune system to kill cancers such as lymphomas in the blood and melanomas in the skin. If you give antibiotics that kill gut bacteria before you give these cancer drugs, the cancer drugs do not work at all
We do not know how safe sunscreens are because they have never been tested systematically. Oxybenzone in sunscreens has been shown to be absorbed into the bloodstream in humans, and to disrupt hormones in animals. Zinc oxide and titanium dioxide appear to be safe, except that manufacturers often convert them to nanoparticles that can be inhaled.
Osteoarthritis affects almost 30 million North Americans, making it the most common joint disease. It damages cartilage most often in the knees, hips, fingers and spine and is associated with aging, trauma, and obesity, but its primary cause now appears to be an overactive immunity that damages joints.
Contrary to what you may have heard previously, it now appears that any amount of alcohol can be harmful. Researchers reviewed more than 50 studies involving more than 260,000 people and concluded that reducing alcohol consumption helps to prevent heart attacks, whether a person is a light, moderate or heavy drinker
Researchers reviewed the medical records of 55,593 men who were given testosterone for low testosterone levels and/or sexual dysfunction and compared them to men who received Viagra or Cialis but no testosterone. After three months, the risk for heart attacks was double in the testosterone group for all of the men older than 65,...
Researchers at Stanford reviewed the medical records of nearly three million people and found that those who took a type of ulcer medication called Proton Pump Inhibitors (PPIs) were almost 20 percent more likely to suffer heart attacks than those not taking these drugs (PLoS ONE. June 10, 2015). PPIs reduce excess stomach acidity...
Ductal Carcinoma In Situ (DCIS) is a non-invasive cancer in the end ducts of the breast. Each year 64,000 American women are diagnosed with DCIS, amounting to 30 percent of women diagnosed with breast cancer. Almost always it shows up as tiny calcium spots on a mammogram in women with no lumps and no symptoms. It is not an immediately life-threatening cancer, and some experts question whether it should be called a cancer.
Doctors often prescribe aspirin and nonsteroidal medicines to people who suffer pain from surgery and injury, but they do not help you recover faster from muscle injuries (1,2,3) , broken bones, joint damage, surgery including joint replacement (12) or muscle soreness after hard exercise (4)/ and they can cause diarrhea, belly pain and bleeding. What you gain in pain control, you may lose in actually delaying healing
A seven-year study of 992 patients with colon cancer that had already spread to their bellies had a 42 percent reduction in death rate and a 31 percent reduction in recurrence of their cancer when they avoided overweight, exercised regularly (one hour of walking per day), ate a diet rich in whole grains, vegetables and fruits, and low in red meat and processed meat, and restricted alcohol.
Two blood tests that are done during routine physical exams can be used to predict whether you are at increased risk for a heart attack. It's called the triglyceride/HDL ratio, calculated by dividing your triglycerides number by your HDL number.
Statins are widely used to help prevent heart attacks, but a new study shows that the same process that causes this class of drugs to reduce heart attack risk can also increase memory loss, muscle problems, joint pains and diabetes (American Journal of Physiology - Cell Physiology, July 29, 2015). Progression to a Heart Attack Susceptibility...
A study from China shows that antioxidant pills caused mice with liver cancer or colon cancer to have their cancers spread rapidly though their bodies. The authors then tested antioxidant pills on cells taken from patients with malignant cancers and grown in test tubes. The antioxidants caused the human cancer cells to grow faster and spread through the cultures. Overall, the conclusion from this and several other cancer studies is that antioxidants can help healthy cells to be protected from free radicals in the body, but they can cause already-developed cancer cells to grow and spread.
Changes in diet should be the first strategy for anyone with high blood pressure, but most people will need to make drastic changes in their eating habits to succeed. Scientists at the National Institutes of Health have shown why the DASH diet lowers high blood pressure to normal in more than 80 percent of...
Two to three million years ago, our pre-human ancestors had a single genetic mutation in their CMAH gene that protected them from a deadly form of malaria but set them up for risk for heart attacks that increases when they eat a lot of meat from any kind of mammal (PNAS, July 22, 2019)....
Nobody knows exactly why overweight is associated with increased risk for so many types of cancer, but the most likely explanation is that storing fat in your belly means that you store excess fat in your liver. Your liver controls blood sugar levels.
A just-published study shows that drinking either sugared or artificially-sweetened drinks is associated with increased risk for diabetes (Am J Clin Nutr, Jun 28, 2017). Of 64,850 post-menopausal women followed for 8.4 years, 4675 developed diabetes.
If you suffer from severe back pain and your doctor has not found a cause, ask him or her if you need a bone density test to determine if you have osteoporosis. All women and most men will suffer osteoporosis if they live long enough.
Post Traumatic Stress Disorder, or PTSD, means that a person has excessive fear, depression and inability to function normally after witnessing or experiencing intense fear or helplessness. While most commonly associated with veterans of combat or captivity, PTSD can also occur after:
Achilles tendonitis Athlete's Foot Bunions (Hallux valgus) Corns and Calluses Cracked Skin on Heels Flat Feet Fungus toenails Gout Hammertoes Ingrown Toenails Neuroma (pinched nerve between foot bones) Orthotics Plantar fasciitis Stress fractures
When patients come to me with pain in the chest and I feel swelling and they hurt when I press on ribs just to the side of the large bone in the middle of the chest, I often diagnose a usually harmless condition called Tietze's syndrome, also known as costochondritis. Chest pain can be a...
Sleeping with the lights on or a television set on for just one night raises blood sugar, heart rate and insulin resistance, all risk factors for diabetes. Five to ten percent of the light can actually get through a closed eyelid. An elevated nightly blood sugar, called the "dawn phenomenon," increases risk for heart disease and diabetes
There is no good data to show that electro-magnetic fields (EMFs) produced by electric blankets, cell phones and other devices cause cancer. Electric blankets do emit radiation from the movement of electric current through wires. Extensive studies in animals have repeatedly failed to show that low-frequency radiation EMFs cause cancer.
Colon cleansers are foods and laxatives that loosen your stool and make you go to the bathroom. The latest research shows that regular use of laxatives or colon cleansers can harm you by blocking the absorption of healthful nutrients from your colon into your bloodstream.
