CHANGE SPEEDS TO BURN MORE FAT - one technique some exercise experts are recommending to increase physical strength and aerobic fitness, and greatly increase fat-loss is called intermittent training. It involves breaking up your regular aerobic exercise with a few minutes of sprinting or other high-intensity work. In a recent study, eight men and nine women participated in a 20-week trial comparing a typical, continuous low-intensity workout to an intermittent workout of equal length. While the low-intensity workout burned more calories, fat loss was nine times greater for those who exercised at high intensity. The researchers speculate that the intermittent routine trains the body to burn more fat even when one is at rest.

Intermittent training can be attained when running, stair-climbing, rowing or exercising on a machine that lets you vary the resistance or intensity. An example would be a 30-minutes training session on an exercise bike. After about 10 minutes of low intensity, just breaking-a-sweat exercise, pick up the intensity for about two minutes to the point of labored breathing. After this two minute session, bring the level back down to normal. Then ten minutes later, again pick up the pace. It is similar to wind-sprints, but at a more relaxed and moderate pace.

SPARE THOSE NUTRIENTS - vegetables actually retain more of their vitamin content when you microwave rather than steam them. The reduced cooking time and water requirements, combined with the unique action of the microwave cooking, are less damaging to heat-sensitive vitamins. Remember not to salt vegetables before cooking them; it will cause them to toughen, discolor and dry out.

And size does matter - when microwaving vegetables, that is. It affects cooking time, so if cutting up the vegetables, try to keep the pieces about the same size. Men's Fitness 6/95

EDIBLE EYE PROTECTION - not only will eating spinach, kale, or mustard greens at least once a week protect your eyes from damaging blue light, but these leafy greens provide more protection than time-honored carrots. A recent Massachusetts Eye and Ear Infirmary study showed that people who ate antioxidant-rich fruits and vegetables five or more times a week have half the risk of developing age-related vision degeneration as less-healthy eaters do. Researchers suspect the benefits of dale, mustard greens and spinach stem from lutein and zeaxanthin, two antioxidants present in the vegetables. Men's Fitness 6/95

MEANING OF BLOOD PRESSURE NUMBERS - Your blood-pressure reading consists of two numbers: the top one is the systolic pressure; it measures how forcefully the heart pumps blood. When it's too high, your heart is working harder than it should. The bottom number is the diastolic pressure; it gauges the force of blood flowing through your fully relaxed arteries between heart-beats. A high number here could indicate clogged or constricted vessels, though both numbers need to be evaluated together. A reading of 120/80 or lower is considered good. Repeated readings of 140/90 or above mean high blood pressure. Men's Health 9/95

WEIGHT TRAINING PLATEAU?-LIFT LESS TO GET STRONGER - if you have been weight training for some time and find yourself not making any progress, try using LESS - not more weight.

In one study, nine weight trainers worked out for three weeks. After that, for 10 days, they lifted the same amount of weight but cut the number of lifts they did by two-thirds. Cutting back the weight was the key. When the test subjects returned to their regular routines, they were stronger than before. According to Tom R. Baechle, Ed.D., chair of exercise sciences at Creighton University, "The less-intense workouts allow your muscles to recover and get stronger." Men's Health 4/95

STOMACH WOES - are you a sugarless gum-chewer who suffers from chronic gas or diarrhea? One possible problem is the sweetener used in the gum - sorbitol. The bacteria in the digestive tract breaks down the sorbitol, producing large amounts of gas that swells the colon and causes pain and cramps. Also, the body sends lots of water to flow into the G.I. tract, causing diarrhea. This is all simply solved by stopping consumption of products containing sorbitol, xylitol, or mannitol. Also these products are sometimes listed as sugar alcohol. Men's Health 9/95


BETTER THAN VITAMINS-PHYTOMINS - this is the latest "buzzword" in nutritional circles. Researchers have discovered a bunch of compounds buried in broccoli, onion, tomatoes, and other common fruits and vegetables that could be the most potent heart-protectors and cancer fighters discovered yet. They are officials known as "phytochemicals", but are becoming popularly known as "phytomins" (pronounced fight-a-mins). These compounds act in plants like white blood cells do in our bodies-to help the plant fight bacteria, viruses, fungi and insects, defend against dehydration, and harmful ultraviolet rays, and finally to stimulate chlorophyll production. According to Herbert Pierson, vice-president of Preventive Nutrition Consultants of Woodinville, Washington and a former project director with the National Cancer Institute, these compounds may help keep arteries clear of cholesterol, bolster resistance to cancer, neutralize toxins, reduce inflammation, and even prevent premature aging. Here are a few of the identified phytomins and how they may help you:

FLAVONOIDS -these compounds are found in wines. Researchers used to think that the alcohol in wine helped Europeans, who typically consume a high-fat diet, keep a very low death rate from heart disease (2.5 times lower than the U.S. rate). But now research indicates that it may to the flavonoids present in the grape skins. When allowed to steep, these skins impart their dark purple color to wine, along with their powerful nutrients. These may keep blood cells from clotting and causing a heart attack. White wine and mixed drinks (including Wild Turkey) don't have as pronounced an effect (sorry, Herb!). Other good sources of flavonoids include fruits (like cranberries, apples, and citrus fruits with their peels and pulp intact), and vegetables like onions, kale, green beans, broccoli, endive, and celery. Green and black teas also score high in flavonoids, along with naturally dark beers. Researchers at the M.D. Anderson Cancer Center in Houston believe that flavonoids also have a strong anti-cancer effect.

CAROTENOIDS - chiefly in this group is beta-carotene, which our bodies convert to vitamin A - a strong anti-oxidant. But there are over 600 other carotenoids, and current research indicates that many of them have similar disease-fighting properties. For example, people in Italy who ate seven or more servings of raw tomatoes every week had 60 percent less chance of developing colon, rectal, and stomach cancer than those who ate two servings or less weekly. Tomatoes are rich in a carotenoid called lycopene. This phytomin survives heating and processing, so it is present in tomato paste, sauce, juice, even ketchup and pizza.

Other carotenoids meriting study are canthaxanthin and lutein. Canthaxanthin is found in certain mushrooms, and seems to inhibit cancer growth. Lutein, found in spinach and kale, may protect against cataracts, as well as many cancers.

GENISTEIN, DAIDZEIN, and SAPONINS - no this is not a law firm. These phytomins are present in soybeans. Genistein and daidzein are reported to inhibit cancer growth in early stages. Saponins can lower blood cholesterol. One of the best ways to get soy protein into your diet may be to try some of the new meatless soy-burgers that are offered in restaurants and in certain markets. Try a variety of these as some are pretty bland, but a few are very similar to hamburger.

In summary, the best source of phytomins are fresh fruits and vegetables. Check out this issue's "Top Ten List" - it is loaded with great sources of phytomins.

THE BIG CHILL - common first aid for minor sprains involves icing the damaged tissue. Now medical researchers have determined that 25 minutes is the optimum time to ice the area. Researchers at the University of Chicago's Orthopaedic Surgery and Rehabilitation Medicine Center studied various icing times by packing the knees of volunteers with ice and measuring the decrease in blood flow, which reduces swelling. The healing effect began 5 minutes and reached a peak at exactly 25 minutes. Icing for longer than 30 minutes can cause damage to the tissue and nerves.

The best way to ice a strain is to fill a gallon-sized plastic bag with crushed ice, wrap it around the entire joint and strap it tightly in place with an elastic bandage. Men's Health 6/95

RELIEF FOR ALLERGIES - allergy sufferers may get some relief from vitamin C. According to Leonard Bielory, M.D., director of allergy and immunology at the University of Medicine and Dentistry of New Jersey, daily supplements of 500 milligrams of vitamin C may help ease allergy and asthma symptoms. Dr. Bielory reviewed more than 40 studies and found a link between short term use of the vitamin and fewer respiratory infections, less frequent asthma attacks and less nasal congestion, watery eyes and other allergy-related miseries.

KITCHEN HYGIENE - think the USDA is doing a good job of protecting the beef and chicken that your family consumes? Just consider that the typical inspector of beef or poultry have all of ten seconds to examine each 1,000 pound carcass as it comes whizzing by on the conveyor belt. Poultry inspectors check 90 birds a minute. All the inspectors do is jab a suspicious looking piece of flesh or sniff around for spoilage. No microscopes or laboratory analyses, just a quick glance, whiff, and pat. It has been this way for over 100 years, when meat inspections were introduced.

What can you do? At-home hygiene with these food products can minimize risk to you and your family. According to Chuck Gerba, a microbiologist at the University of Arizona, who specializes in household contamination, "people don't realize that sponges and dishrags are breeding grounds for disease-causing bacteria..I never shake the hand of a person who's handled one." Here are three of Mr. Gerba's "kitchen germ-warfare weapons":

-Use paper towels. Wipe up...then toss it out. Bacteria will not be spread around.

-Run sponges, dishrags, and scouring pads through the dishwasher. "You need to do it every day because things grow like crazy overnight," according to Gerba.

-Use a product like Lysol's new antibacterial kitchen cleaner. Antibacterials can reduce kitchen contamination by more than 90 percent, says Gerba. (The FDA has not yet endorsed this method of cleansing - editor.) Nutrition Action Health Letter 4/95


THE BATTLE OF THE BULGE - doctors from Northwestern University Medical School think they know why even thin men have "pot bellies." Late night dining and sleeping on a full stomach allows the muscles that help hold in your gut to relax. Food in the stomach takes advantage of this, pressing against those relaxed muscles, stretching the midsection outward, eroding its tone and making the belly sag.

Remedies include stop eating late meals followed immediately by sleep periods, and start doing abdominal and lower back exercises three to four times a week. The exercises keep stomach and ab muscles tight even when relaxed.

NATURE'S PROZAC - according to data in the Journal of Personality and Social Psychology, researchers found that exercise was the most effective weapon against "the blues". The doctors feel that the mental lift occurs because exercising eases muscle tension, which distracts from worries, and releases endorphins, the body's chemicals that stimulate the brain to block pain.

GOOD TO THE LAST DROP - up to 40% of the vitamins in a bowl of cereal dissolve relatively quickly into the milk. To make sure to get the most vitamins from fortified breakfast cereals, drink the leftover milk, says Richard Wood, Ph.D., of Tufts Human Nutrition Research Center.

PROSTATE CANCER, PART III - conventional treatment for prostate cancer can include surgically removing part or all of the prostate gland and radiation therapy. These methods may leave the patient impotent, incontinent or both. But a new option is being used now that involves placing a rice-sized radioactive "seed" directly in the prostate gland. This sharply reduces the risk of complications. Researchers at Seattle's Northwest Tumor Institute claim this new outpatient technique is 100% effective in controlling aggressive, early-state prostate cancer. In a five-year clinical trial, implants of TheraSeed-Palladium stopped the spread of cancer in each of 111 men with significant tumors. Men's Health 7/95

VITAMIN E, THE LUBRICANT - as previously reported in "Crossfeed", vitamin E supplements can reduce risk of heart disease and certain cancers. But there was debate on the amount that needed to be consumed for these benefits to be attained. Now according to the University of Texas Southwestern Medical Center, 400 IU of vitamin E supplements taken daily significantly lowers the chances of LDL cholesterol sticking to artery walls. This is significant as many multivitamin tablets contain only 50 to 100 IU of vitamin E. According to the study, this lower amount of vitamin E would not be as effective in reducing risk of heart disease as consuming the 400 IU daily.

TONIGHT'S TOP 10 LIST: FOODS THAT YOU SHOULD NEVER EAT;

10. Regular turkey or chicken franks - just because it's not beef doesn't mean that it is healthy. Turkey franks by Tyson, Weaver, or Mr. Turkey contain 11 to 12 grams of fat each. But Butterball, Healthy Choice, and Oscar Mayer make turkey, pork, or beef franks with zero to 1 1/2 grams of fat. Read those labels!


9. Contradina Alfredo Sauce - equates to 1/3 of a stick of butter in terms of fat. Instead try Enrico's No Salt Added, Tree of Life, Colavita, or Classico's Spicy Red Pepper spaghetti sauces. All are low in bad stuff, but reported to be quite tasty.

8. Nissin Cup Noodles with Shrimp - these noodles are fried (in palm oil, yet) and salted (yielding over 1,550 mg of sodium). Instead try Fantastic Foods Chicken Free Ramen Noodles.

7. McDonald's French Fries - 22 grams of artery-clogging fat plus salt adds up to a heart attack snack.

6. Dunkin' Donuts Plain Cake Doughnut - yes, you turned-down the glazed and creme-filled beauties, but that plain cake doughnut was fried in shortening, much to your cholesterol's detriment.

5. 78% LEAN GROUND BEEF - which is 22% fat which is bad. Ground beef that is 90% lean may be classed as "lean". But even this "lean" product has 11 grams of fat in three ounces of cooked meat (if you let the fat drip off). Fat can be cut to three grams if your local butcher grinds up turkey breast without skin. Products that list turkey as their only ingredient could contain skin-it's part of the turkey, but it is very fatty.

4. RICE-A-RONI CHICKEN & VEGETABLES - one cup contains 1,470 mg of sodium - over 1/2 the daily max. Veggies are sparse in this product - the name should have been "Rice & Salt"! Substitute Marrakesh Express CousCous or Terrazza Pasta & Beans, which cuts about 90% of the salt. Even Uncle Ben's Country Inn Recipes (Chicken & Rice) has less than half the sodium of the Rice-A-Roni.

3. OSCAR MAYER LUNCHABLES - contains more fat than a Quarter Pounder and twice as much salt. Try Reduced Fat Triscuits (they're whole wheat) and a couple slices of Louis Rich Oven Roasted Fat Free Turkey Breast. Almost no fat and less than half the sodium.

2. HAAGEN-DAZS EXTRAAS - each cup has more fat than two Big Macs. Try low-fat or non-fat frozen yogurt, instead. (No toppings, please!)

1. STICK BUTTER OR MARGARINE - don't buy either if it's in a stick. One tablespoon of stick stuff has seven grams of saturated fat, a third of a day's worth. Instead, try a tub. Even butter has less fat if it comes whipped in a tub. Best bet of all; squeeze bottles (less fats) or butter substitutes in baking (like prune butter or apple sauce).

LAUGHTER IS THE BEST MEDICINE - two new studies offer further evidence that laughter does indeed have healing power, according to a report in the Journal of the National Cancer Institute. In the first study, 10 healthy men were shown an hour-long humorous videotape (perhaps your last PC!). Immediately afterward, their blood showed an increase in interferon-gamma, an important healing chemical in the immune system. In the second, stress was measured in subjects shown a videotape of gory accidents. When they were asked to describe the accidents in a humorous way, physical measurements indicated their stress levels were lower than when they were asked to give a serious description.
