Number 154: Caffeine and Diabetes

  • My New Diabetes Articles for HealthCentral:

    Last month HealthCentral published five more of my diabetes articles about all aspects of the condition:

    Who knows whether coffee is good or bad for people who don't have diabetes. But for us who have it, studies show that caffeine exaggerates the rise in glucose when we eat carbohydrates. This is either a reason to avoid coffee or cut out starch and sugars.

    Many people with diabetes still take one of the insulin secretagogues. But metformin may be a better choice. A huge study of more than 100,000 people in Denmark compared the prevalence of heart attacks and strokes suffered by people who took insulin secretagogues and metformin. Those who had not already had a heart attack had a fifth to a third higher risk of death from any cause if they were taking one of the insulin secretagogues. Among those who had already had a heart attack the risk was a third to a half higher.

    A new study of people with pre-diabetes shows that they get remarkable benefits from support groups. If group support helps people who have pre-diabetes, it is probably much more likely to help those of us who are already burdened with this condition. Now more and more of us are choosing to get online support.

    Moderate amounts of red pepper can help us lose weight. Enjoy the burn!

    A new study shows that fasting lowers the risk of heart disease and diabetes and increases the good HDL cholesterol and reduces triglycerides, weight, and blood glucose levels. Yet it also increases the bad LDL cholesterol.

  • Fitness and Photograph for Fun:
  • Last month I published seven more of my articles on staying fit by getting the activity we need. Photography is what does it for me:

    The resident birds that I photographed this month were a pair of Great Horned Owls on a nest at Twin Lakes, just north of Boulder. The most distinguished visitor was a lone Tundra Swan.

    On this visit to Twin Lakes I found both the female and male Great Horned Owl. But this time the family had an addition. They have a baby.

    The tours of Rocky Mountain Arsenal National Wildlife Refuge have to be the best bargains anywhere to see birds and other wildlife. They are free, and I took several of them there this month.

    In the past few days at least four species of ducks have been adding their beauty to Tantra Lake in front of my apartment. Some of these are among the most beautiful ducks anywhere, and I photograph them.

    Greater Prairie-Chickens
    Photographing some so-called chickens this month was one of the most memorable experiences of my life. Male Greater Prairie-Chickens, which are actually in the grouse family, displayed on a lek to attract females. And what a show they put on!

    I went to Wray, Colorado, to see the dance of the Greater Prairie-Chickens. On the way to Wray I found innumerable ducks and geese.

    Owls, hawks, and more delighted me around Wray, Colorado, which I visited so that I could see the dance of the Greater Prairie-Chickens there.
