We all know that physical fitness is a good thing. Fitness is associated with heart and lung health, good blood sugar control, and a longer, more productive and enjoyable life. But what does it actually mean, and what do you have to do to get and stay fit? Although some definitions of fitness also include muscle strength, flexibility and body composition, fitness usually refers to cardiovascular fitness, or aerobic capacity—the ability of your heart, lungs and circulatory system to supply oxygen-rich blood to muscles and organs and remove metabolic waste products during exercise. You can assess your own aerobic capacity to some extent by how winded you get climbing stairs, lifting heavy packages or running for a bus. A more scientific home test is given here. You can also go to a clinic or health spa and have it measured by exercising as hard and long as you can on a treadmill while your heart rate and breathing capacity are measured. According to studies done at the Cooper Inst…

Nutrition experts at Tufts University say the average American consumes about 30 teaspoons of “added sugar” (that is, sugar not found naturally in food) a day. That’s a heck of a lot if you believe, as we do, that refined sugar and high fructose corn syrup are deadly metabolic poisons, and just 2 teaspoons of them throws your body into biochemical chaos for several hours. Or that honey and other natural sweeteners aren’t a whole lot better and should be used sparingly. Although the sugar industry keeps trying to convince the government and consumers that any form of sugar is safe in any amount, they’re fighting a losing battle. The science saying otherwise has become so overwhelming that even the conservative American Heart Association now agrees that added sugar is implicated in obesity, high blood pressure and other risk factors for heart disease and stroke. They recommend no more than 6 teaspoons of sugar per day for women and 9 for men. Last year, government Dietary Guidelin…

Life is hard enough without making losing weight more difficult than it needs to be.  Some helpful scientists at the University of Massachusetts Medical School proved that you don’t need to restrict calories or saturated fat to lose weight as long as you’re getting adequate dietary fiber! These scientists found 240 pre-diabetic patients and assigned them to one of two groups. The first group followed a weight-loss diet that restricted calories and saturated fat. The second group was simply asked to get at least 30 grams of fiber daily from a high-fiber diet, including plenty of fruits, vegetables and whole grains. Neither group was asked to change their exercise habits. At the end of one year, both groups had lost the same amount of weight.  In addition, both groups had had similar drops in cholesterol, high blood pressure, high blood sugar, and inflammation.  In other words, both groups reduced their risk factors similarly for diabetes…
