PROTECT YOUR SMILE –
after your morning coffee, wait 30 minutes to brush your teeth. Acidic foods and beverages weaken enamel, and
brushing immediately after consuming them can cause further damage. Men’s
Health, 05/13.
GLUTEN FACTS –
there has been much in the media about gluten-free dieting…from Dr. Oz to diet
books touting its benefits. Gluten is a protein found in wheat. Just 0.71 percent of Americans experience an
abnormal immune system reaction to gluten.
If eating wheat products seems to cause gastrointestinal discomfort,
canker sores, or a rash, try keeping a food log when these symptoms occur,
listing what food was consumed and when.
If gluten is the common factor, go without it for two weeks while
keeping up with the dietary diary. At
the end of this washout period, revert to the former diet with your normal
gluten intake for two more weeks. If you
react to the inclusion of gluten in the diet, you may wish to eliminate gluten
foods permanently. Your physician can order blood tests that can detect some of
the antibodies associated with celiac disease. Remember to keep eating gluten
foods before the test to obtain accurate test results. Men’s Health, 04/13.
EXERCISE FOR
ALLERGY RELIEF? – According to a study from Thailand, exercise can help
relieve allergy symptoms. After allergy
sufferers ran for 30 minutes, their sneezing, runny nose, and nasal itching and
congestion all decreased by more than 70 percent. One theory is that cardio exercise decreases
inflammatory proteins in the nasal passages.
The scientists recommend a moderate pace (65 to 70 percent of your heart
rate reserve - calculated by subtracting your resting heart rate from your
maximum heart rate). Maximum heart rate
is your age multiplied by 0.7 and then subtract the result from 207. Men’s Health, 04/13.
SUNSCREEN USE SLOWS
SKIN AGING – an Australian study published in the journal Annals of Internal Medicine provides
compelling evidence that daily sunscreen use reduced photo-aging (the visible
signs of aging caused by the sun’s ultraviolet rays) by 24 percent. The study’s test subjects used a
broad-spectrum sunscreen with an SPF of 15.
Besides reducing the visible effects of aging on the skin, the study’s
subjects also reduced their risk of skin cancer. USA

MINIMIZING PROSTATE
CANCER RISK – “maintaining a healthy
weight is good for preventing chronic disease,” states a researcher who is
an expert in the epidemiology of prostate diseases at the Washington University
School of Medicine. Research from Europe
showed that men with the most visceral fat (the belly fat that surrounds the
organs in your core) also had the highest risk of prostate cancer. That is because visceral fat produces
inflammatory substances that disturb the metabolism and promote the growth of
cancerous cells. To aid in reducing
weight, increase your intake of fruits and vegetables that are high in
antioxidant flavonoids, such as oranges, grapefruits, strawberries, onions, and
greens. The fiber can fill you up while
the flavonoids may lower our risk of aggressive prostate cancer. Besides eating a healthier diet, increasing
workouts, especially with high-intensity interval training is a proven way to
reduce visceral fat.
Green tea has long been touted by the Chinese for its
medicinal value. The green tea health benefits could include cutting a man's risk
of advanced prostate cancer by half. How much do you need to drink? In a study,
men who drank 5 or more cups of green tea per day had half the risk of advanced
prostate cancer compared with men who sipped less than a cup a day. Another way
to ensure a healthy prostate: Avoid a diet high in saturated fat and include
plenty of fruits and veggies in your diet. Men’s
Health, 03/13, Real Age 07/31/13.
MAGNESIUM-RICH
FOODS MAY REDUCE RISK OF COLORECTAL CANCER – a study and research analysis
in the American Journal of Clinical
Nutrition suggested that this potential benefit was only valid in
overweight or obese people over 55. In
the analysis, which included data from nine previous studies, each
100-milligram daily increase in dietary magnesium was associated with a 12
percent lower risk of colorectal cancer.
That is the amount in four ounces of fish, a cup of beans, two ounces of
peanuts, or half a cup of cooked spinach.
Most other studies have confirmed these results. Magnesium-rich foods also have healthful
benefits for the heart, bones, and blood sugar control. University
of California Berkeley Wellness Letter, 01/13.
WARNING: DO NOT MIX
– even the most common supplements can have surprising interactions with
drugs and other supplements. Below are
just a few:
FISH OIL-
Taking fish oil with blood pressure-lowering drugs can increase the effects of
these drugs and may lower blood pressure too much. Taking high doses of it with herbs that slow
blood clotting (including ginkgo) may cause bleeding.
CALCIUM-
Calcium can reduce the absorption of many medications, including certain
prescription osteoporosis drugs; antibiotics in the tetracycline and quinolone
families (like Cipro); and levothyroxine, which treats hypothyroidism.
ECHINECEA-
Echinacea’s alleged ability to stimulate the immune system may interfere with
drugs that decrease the immune system, such as the steroid prednisone.
MELATONIN-
Since melatonin may make you drowsy, taking it with sedative drugs may cause
too much sleepiness.
VITAMIN
D- High doses of vitamin D combined with a diuretic medication may result in
too much calcium in the body, which can cause kidney problems. Health,
12/10.
MERCURY AND
DIABETES – studies in animals suggest that mercury can damage the
pancreatic cells that produce insulin.
Now scientists have found a link between mercury and diabetes in
people.
Researchers
followed adults aged 20 to 32 in the Coronary Artery Risk Development in Young
Adults (CARDIA) study. All supplied
toenail clippings when they entered the study.
Those with the highest levels of mercury in their toenails had a 65
percent greater risk of diabetes over the next 18 years than those with the
lowest levels.
People
with the higher mercury levels were healthier – they were less likely to be
overweight, had smaller waists, did more exercise, and were less likely to
smoke. They were also more educated and
consumed more magnesium, omega-3 fats, and fish (which is probably where they
got the mercury).
Yet when
the researchers took those and other factors into account, the high-mercury
group still had a higher risk of diabetes.
This
study does not prove that mercury causes diabetes, but to protect the
developing nervous system, health authorities already advise children and some
women (those who are nursing, pregnant, or may become pregnant) to avoid
mercury. These groups should eat no
albacore tuna, shark, swordfish, king mackerel, or tilefish, and should limit
light tuna to 2 ounces a week (half that amount for children under 55
pounds). Other adults can eat up to 3
ounces of albacore, or 12 ounces of light tuna a week.
Everyone
should aim for two servings of fish a week.
Low-mercury fish include salmon, freshwater trout, catfish, and
tilapia. Diabetes Care 2013.
