HEALTHY CHOICES

If you are a confirmed coffee drinker like I am, it may be hard to convince you to buy a few green tea bags and join tea drinkers around the world. Below is an excerpt from our first volume of Lipstick Logic Health Series which will become an e-book available in February. As I am sure you know, heart disease in women is different in some aspects and can be more difficult to diagnose.

Volume One, Your Heart, covers the latest information on heart disease, interventions and lifestyle changes to improve health.

February is not only Valentines day, the first Friday, February 1st, is also the annual Go Red For Women Heart Association alert to educate yourself and live healthier and longer. If you would like to know when the book becomes available, please sign onto our website readership.

Coffee

Coffee is good for you, but like everything else you do, use moderation. Numerous studies show a reduction in Type II diabetes in those who drink either caffeinated or decaffeinated coffee. In one study of about 193,000 people, those who drank 6-7 cups a day were 35% less likely to develop Type II diabetes than those who drank less than two cups a day. Even drinking 4-6 cups per day lowers the risk.

Freshly brewed coffee contains antioxidants. Minerals including magnesium and chromium in coffee are involved in insulin function. Lowering risk for diabetes reduces the risks for both heart attack and stroke.

One would think the stimulant effect of coffee would be detrimental because caffeine can stimulate epinephrine and raise blood pressure. Studies show an actual reduction in heart rhythm disturbances.

Two studies showing favorable effects from coffee consumption are the long-term study on 83,700 nurses enrolled in the Nurses’ Health Study which showed a 20% lower risk of stroke in those who drank 2 or more cups per day over non-coffee drinkers. In another study on 130,000 people who drank 1-3 cups per day, they were 20% less likely to be hospitalized for heart rhythm issues than nondrinkers.

In addition to the above benefits, there are clear links to decreased risk of Parkinson’s disease and Alzheimer’s dementia in coffee drinkers.

The downside is the things you add to coffee. Plain black coffee has fewer than ten calories. Add a teaspoon of sugar and you have added 23 calories. Adding half and half or liquid non-dairy creamer increases the calorie content by 50. Check the calories of what you add and see if you want to spend daily calories that way or learn to drink it black. Some coffee specialty drinks contain as much as 500 calories, a meal in itself. Also, if you are having daily barista coffee drinks, these hidden calories can jeopardize weight control goals and are expensive. Second only to crude oil, coffee is big business.

If you look around, may find a “new” coffee drink to interest you-tea made from coffee plant leaves. This drink was popular for a while in the 1800s but didn’t catch on in England. A recent article in the Canberra Times reports an Annals of Botany publication stated “Coffea arabica leaves have higher levels of antioxidants, which is thought to be beneficial in combating heart disease, diabetes and even cancer, than tea or coffee.” Coffee plant leaf tea is currently available in some health food stores.Coffee beans and hands

Green Tea

Benefits of drinking green tea have been touted your years. Does this mean a confirmed coffee drinker should acquire a taste for tea? Maybe. It sounds bland, uninteresting and if it is calorie-free, how good can it be?

Green tea contains micronutrients called catchins. These are antioxidants which scavenge the free radicals we want gone. An animal study at McGill University in Montreal on one component of the catchins found it effective in treating prostate tumors. Human studies are hopeful. In the lab, the green tea substance inhibits cancer growth and kills abnormal cells. In a study involving 500 Japanese women with breast cancer, those who drank increased amounts of tea before and after surgery had lower cancer recurrence. Another cancer that may be suppressed is lung cancer. Twenty-two studies analyzed showed drinking two cups of green tea (not black) resulted in an 18% decreased in developing lung cancer. If you are already a tea drinker, but it isn’t green, give it a try.

Another healthy aspect of green tea and others from the Carnellia sinensis plant (Black and Oolong) is the content of bronchodilators. If you know someone with asthma, you’ll know what we mean. Theophylline and theobromine in tea both act on the lungs by relaxing tight airways allowing better airflow. Tea can help calm cough in mild lung conditions.

Some studies show green tea aids weight loss, reduces LDL cholesterol, lowers blood pressure and relaxes blood vessels improving heart health.

If all these positive aspects of tea haven’t convinced you to drink a couple of cups a day, maybe this will: Green tea suppresses bacteria in the mouth and GI tract and may not only combat tooth decay, it might help infectious diarrhea. Because of its medicinal effects, lotions, bath salts and even a prescripted green tea ointment clears warts!

I’ll drink to that!
