All men and women will develop osteoporosis if they live long enough and the best way to prevent this increased risk for breaking bones may well be a resistance exercise program. A study from Romania found that a resistance training program markedly increased the bone density of osteoporotic women, average age 56 years, in just six months.
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.
A recent Danish study followed 54,903 healthy men and women, 50-64 years old, for 16 years. Those who ate primarily fermented dairy products such as cheese and yogurt were significantly less likely to suffer heart attacks than those who drank milk.
People who take aspirin are at reduced risk for colon cancer, unless they are among the four percent of North Americans who have a genetic susceptibility for colon cancer (JAMA, March 17, 2015;313(11):1133-1142). Colon cancer is the second leading cause of cancer death in the United States (after lung cancer), with 1,162,426 people living...
Researchers have suggested a method to measure antibodies in humans after they eat the foods that contain Neu5Gc (BMC Medicine, Oct 23, 2020;18(262)). The more meat and dairy a person eats, the higher the rise in antibodies against Neu5Gc.
A study of more than 3,400 former National Football League players, average age 52, found that those who had had a concussion were at increased risk for low testosterone and erectile dysfunction, regardless how young or old they were.
Nearly fifty percent of people over 85 suffer from symptoms of dementia of which Alzheimer's disease, a progressive loss of brain cells, is the most common form. The second most common type of dementia comes from repeated strokes. This month researchers offer strong evidence that Alzheimer's disease may be started by an infection.
Two recent breakthrough studies give the best explanation yet of how exercise helps to prevent heart attacks. Competitive older endurance athletes may have more plaques in their arteries than non-exercisers, but they have the type of plaques that are far less likely to break off and cause heart attacks.
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.
Being overweight is associated with having larger plaques in the arteries leading to the heart and a marked increase and progression of these arterial plaques that cause heart attacks, even if a person does not have the risk factors that predict increased risk for diabetes and heart attacks.
A liver full of fat can be caused by anything that damages the liver. Doctors used to separate liver damage into that caused by alcohol and that not caused by alcohol (non-alcoholic fatty liver disease or NAFLD). Now we know that a liver damaged by excess alcohol has the same harmful consequences as a...
A healthful plant-based diet can help to cure Type II diabetes if you already have it, or help to protect you from developing diabetes in the first place. People who eat the healthful plant-based foods -- vegetables, fruits, whole grains, beans, nuts and other seeds --are far better protected than those who eat the "unhealthful" plant-derived foods, such as refined grains, fried potatoes and sugar-added foods
Sunscreens offer only partial protection from the sun. It is dangerous to expose large areas of your sun screen-coated skin to sunlight. If you want to really protect your skin from sun damage, get under a roof when the sun is out in full force. Clothes are next best, and sunscreens are a poor third.
If you develop dizziness that lasts for more than a few seconds, check with your doctor. it could be a stroke. Recurrent dizziness can be caused by temporary interruption of circulation to your brain, such as blocked neck arteries or an irregular heart beat. It can be caused by a stroke, tumors on the...
Your body uses inflammation to protect you from invading germs and to heal injuries. When a germ gets into your body, you make cells and proteins to kill that germ. As soon as the germ is gone, your immune system is supposed to dampen down and stop making large amounts of these cells and antibodies.
Studies this month show that neither taking omega-3 polyunsaturated fatty acids (PUFAs) in fish oil pills nor eating fish reduce the risk for heart attacks, September 16, 2016). A review of studies in the world's scientific literature agrees that taking fish oil pills does not prevent heart attacks.
2019 Nobel Prize honors the discovery of how your body responds when you can't meet your needs for oxygen. Their groundbreaking research is now being used to treat certain cancers, strokes, infections, anemia, heart attack risks, and some eye diseases that can cause blindness.
Women are three times more likely than men to develop lupus, multiple sclerosis, or rheumatoid arthritis, currently thought to be autoimmune diseases that are caused by a person's immunity attacking her own body, instead of doing its job of killing germs. This increased risk may be caused in some way by the process of pregnancy, or it may be due to the fact that women are twice as likely as men to become infected with a sexually transmitted disease.
A very important new study of 27,599 adults, average age 47-50, showed that almost 15 percent of North American adults and almost 19 percent of those with high blood pressure take medications that can raise blood pressure. The blood-pressure-raising medicines taken most frequently were antidepressants, NSAIDs, steroids, and estrogens.
Before you jump on the bandwagon of avoiding gluten, consider its benefits as well as potential problems. People who are gluten-intolerant should avoid wheat, barley, rye and probably oats (because of potential cross-contamination). Your doctor can do tests to see whether you are one of the small minority who need to avoid gluten. Otherwise, consider a study from the University of Toronto which showed that a high-gluten diet helps to lower oxidized LDL cholesterol, triglycerides and uric acid.
Medical journals have reported trials that examine the benefits and harms of taking testosterone for men over 65 with low blood levels of testosterone (less than 275 ng/dL). At 12 study sites across the country, a total of 790 participants were given testosterone gel or a placebo applied daily to the skin.
Your blood pressure usually rises as soon as you start to exercise and drops a little bit while you exercise at the same intensity. However, as you continue to increase the intensity of exercise, your blood pressure usually rises higher and higher.
A review of published studies shows that the world-wide incidence of inability to achieve an erection varies widely from three percent to 76.5 percent, and the geographical incidence of impotence is associated with all the same risk factors as those for heart attacks, dementia and having an enlarged prostate (BJU International, July 3, 2019)....
More than nine million North Americans suffer from low thyroid function, but many people are not diagnosed or treated because they have never been tested. One million people take thyroid replacement pills, but some are not being treated properly because they are taking only one thyroid hormone when they need two to really feel better.
A study from the University Hospital in Essen, Germany shows that riding a bicycle does not raise blood levels of PSA, the blood test used to screen for prostate cancer. Several studies suggest that ordinary bicycle seats can cause impotence which can become permanent with continued pressure on the nerves that control erection. Men who...
As businesses and activities are re-opening, many people have decided to relax their precautions to avoid infection with COVID-19. If you are a person who is at high risk for complications from this virus, I believe that you should continue to be on guard.
A huge study from Korea confirms that people with Metabolic Syndrome are at increased risk for heart attacks, and that when they correct some or all of the components of Metabolic Syndrome, their risk for a heart attack goes down dramatically.
