Coffee & Prostate Cancer Prevention Update

This research was published this month in the Journal of the National Cancer Institute. It’s called the Health Professionals Follow-Up Study.

Lead author Mucci’s team followed 47,911 men from 1986 to 2008. During that time, the men kept track of their coffee consumption.

Men with the highest coffee consumption had a 60 percent lower risk of developing a form of the cancer that’s most likely to result in death.

Men who drank six or more cups a day had a 20 percent reduced risk of any form of prostate cancer. Even one to three cups a day corresponded to a 30 percent drop in the risk of lethal prostate cancer.

Mucci said, “Our study is the largest to date to examine whether coffee could lower the risk of lethal prostate cancer.”

What was responsible for the positive results? Researchers credited quinine, magnesium, and trigonelline. These compounds cut inflammation and manage insulin. Coffee also contains antioxidants that fight free radicals and prevent cell-damaging oxidation.

It doesn’t matter if you prefer regular or decaffeinated coffee. Researchers found the same reduction in risk with both.

And for the best protection against prostate cancer, you should drink your coffee black.

Dr. Neal D. Barnard reviewed 12 international studies. He found that “consumption of dairy products is associated with increased risk of prostate cancer incidence and mortality.”

If you need a little milk in your coffee, try almond milk instead.

Coffee

This caught my attention. Hopefully everyone knows I enjoy coffee, not only for the anti-oxidants, but for the pre-workout caffeine it provides. 

Read this conclusion and understand the types of coffee they are studying.

Coffee news!

This study out of the University of Athens (Greece),  analyzed hypertension (high blood pressure) and coffee consumption. Hypertension makes blood vessels less responsive to signals to expand and is a significant predictor of cardiovascular events. They studies the coffee consumption patterns among 435 hypertensive individuals, ages 65 to 100 years, enrolled in a larger study involving the permanent inhabitants of Ikaria Island, where many residents reach 90 years and older.  As compared to those who rarely drank coffee, moderate consumption of one or two cups a day associated with a lower prevalence of diabetes, lower prevalence of high cholesterol, lower body mass index, lower prevalence of cardiovascular disease, and higher values of aortic distensibility.  Proposing that the presence of phenol compounds in coffee may be responsible for these effects, the researchers conclude that: “Moderate coffee consumption has beneficial effects on the aortic distensibility in hypertensive elderly individuals.”

Black Coffee with cream only

I do enjoy a cup of coffee each morning and I believe that it has valuable anti-oxidant properties. I see alot of people get into trouble with coffee though. The coffee industry doesn’t want you to know that the average latte is worse than a double-scoop ice cream cone. No source of sugar is more stealth than the caffeine kicks dished out at coffee shops across America. Even an unflavored 16-ounce latte has close to 200 calories, and for the average person that represents nearly 10 percent of your daily energy requirements. Starbucks alone sells about two dozen drinks with more than 500 calories apiece. (And that’s not even counting the absurdly indulgent and overwrought Frappucinos.) Drink something like that once a day, and you’re facing at least an extra 50 pounds of flab each year!

Coffee: Lastest research

Degree of roasting is the main determinant of the effects of coffee on NF-kappaB & EpRE.
Free Radic Biol Med. 2010 Feb 19. (Epub ahead of print)

Coffee, one of the most popular beverages worldwide, is a major contributor of phytochemicals in the diet and contributes more than 50% of dietary antioxidants in many countries.

A moderate intake of coffee has been linked to reduced risk of chronic diseases. Furthermore, experimental studies demonstrate bioactivity of coffee or coffee compounds in inflammation and oxidative stress, two major, related biological processes.

My take on this – go ahead and drink 2-3 cups a day. Spread it out throughout the day and most importantly, make sure it is organic coffee.

Current Thoughts On Coffee

I often get asked about coffee so I’ll share my current thoughts on so many peoples favorite morning drink. Clients expect me to disapprove of coffee because they think it increases the body’s acidity; or that health-conscious people are supposed to drink green tea instead; or they just think caffeine is bad for you.

Coffee is not harmful, it contains lots of antioxidants. The average amount of coffee consumed by American adults per day- 1.64 cups- provides 1,299 mg of antioxidants. Tea, the second richest source, supplied only 294 mg, followed by antioxidant-rich (but sparingly eaten) fruits and vegetables, which provide fewer than 75 mg each of antioxidants per day. Believe it or not, coffee even contains fiber- nearly 2 g per cup.

Research shows that drinking coffee reduces the risk of Parkinson’s disease by as much as 80 percent and protects against other neurodegenerative disorders such as Alzheimer’s. It increases insulin sensitivity, and a high intake- at least six cups a day- lowers the risk of type 2 diabetes by 54 percent in men and 30 percent in women. I wouldn’t recommend six cups of coffee per day especially if you have high blood pressure.

Coffee improves concentration and alertness and boosts mood. Coffee can help control asthma and can even halt a full-blown attack in its tracks. Additionally, coffee can stop migraine headaches, curb appetite, prevent tooth decay, and increase the effectiveness of aspirin and other analgesics (Anacin and Excedrin both contain caffeine). And if you drink it before working out, your endurance will improve and you’ll have less exercise-induced muscle pain.

Compared to people who avoid coffee, those who drink at least two cups a day are 80 percent less likely to develop cirrhosis of the liver (even if they drink a lot of alcohol), half as likely to have gallstones, and 25 percent less apt to get colon cancer. Coffee is also protective against cancer of the liver and kidneys, and although it’s long been suspected of increasing risk of breast cancer, a recent study spanning 22 years and involving nearly 86,000 women found a weak inverse association between the two in postmenopausal females.

Some studies reveal that regular and decaffeinated coffee both have benefits. Caffeine picks up the nervous system, and increases the activity of the neurotransmitter dopamine and enhances delivery of nutrients and oxygen to the muscles and brain.

So, the next time you feel like a cup of coffee, indulge yourself. It’s a good way to boost your mood, your energy, and your overall health.
