June 3, 2001- Another precious metal-Copper
When University of North Carolina at Greensboro researchers infected human cells with bacteria, they found that the cells with normal copper levels killed two to three times more bacteria than those cells with low copper levels. They also produced up to 60 percent more cytokines--chemicals that trigger the body's immune response. "The fact that these were otherwise healthy cells shows just how sensitive our immune system is to a lack of copper," notes Mark Failla, Ph.D., the study author. One bowl of raisin bran, a slice of buttered whole wheat toast, and a cup of hot chocolate will give you more than a third of what you need each day. Copper has also been spotted in lobster, cashews, and salmon.

June 10, 2001- Ulcer Rx
Ulcers may be one more health worry that regular exercisers can lay to rest. A recent study revealed that physical activity may reduce the risk of ulcers of the duodenum, the beginning portion of the small intestine. In the study, active men had a significantly lower risk of duodenal ulcers than men who were only moderately active.
Exercising regularly can reduce your chances of ulcers and other cardiovascular diseases.

June 17, 2001- A Wash Out
Your kitchen counter and sink may be sparkling, but don't forget to wash that sponge, too.
According to research, sponges and dishcloths may be the most bacteria-laden items in the kitchen. That's because they are the most frequently touched kitchen items and their dampness creates a perfect breeding ground for bacteria. Wash your sponges or dishcloths often and allow them to dry thoroughly. Protecting your immune system can help keep you and your family healthy.

June 24, 2001- Get a Purple Heart
There's mounting evidence that grape juice is good for something besides those cool purple mustaches. A study published in the Journal of Nutrition reports that purple grape juice limits the number of platelets that stick to the walls of arteries and cause plaque buildup. "If you reduce platelet activity, you reduce the risk of heart attack," says John Folts, Ph.D., the study author, from the University of Wisconsin. Orange and grapefruit juices didn't inhibit platelet aggregation. But since they offer other health benefits, try this rotation: Orange, grapefruit, cranberry, grape; orange, grapefruit, cranberry, grape; orange...
