Two more reasons to take turmeric: It protects your heart, fights autoimmune disease


by David Gutierrez, staff writer 

(NaturalNews) You may already have heard that turmeric is a potent anti-inflammatory and anti-cancer food, but did you know that it can also help protect your heart and fight autoimmune diseases?

In a study published in the journal Biological and Pharmaceutical Bulletin in 2011, researchers from Niigata University of Pharmacy and Applied Life Sciences in Japan found that three weeks of supplementation with the turmeric compound curcumin significantly improved cardiac health in male rats who had been given an injection to induce an autoimmune disease of the heart (autoimmune myocarditis). The rats supplemented with curcumin also showed a reduction in the area of the heart covered by inflammatory lesions and a reduction in the heart’s weight-to-body-weight ratio.

“Our results indicate that curcumin has the potential to protect against cardiac inflammation through suppression of IL-1beta, TNF-alpha, GATA-4 and NF-kB expresses, and may provide a novel therapeutic strategy for autoimmune myocarditis,” the researchers wrote.

Turmeric has the distinction of being both one of the most widely used culinary spices and traditional medicines in the world. Its benefits have been well studied by Western scientists, who attribute much of its disease-fighting prowess to a trio of naturally occurring yellow-orange chemicals called the curcuminoids (and sometimes known simply by the name of the most famous of them, curcumin).

As good for your heart as exercise

Turmeric is not just good for the hearts of people with autoimmune myocarditis; in fact, several studies conducted by researchers from the University of Tsukuba in Japan suggest that it may be as beneficial for your heart as aerobic exercise!

In a pair of studies published in the journals Artery Research and Nutrition Research in September and October 2012, respectively, the researchers found that women who took a curcumin supplement showed as much improvement in two measures of heart health (vascular endothelial function and arterial compliance) as women assigned to a moderate aerobic exercise training program. An even greater benefit was seen, of course, in those who took the supplements and engaged in the exercise program as well.

In another study, published in the American Journal of Hypertension in June 2012, the researchers found that a combined exercise and curcumin program significantly slowed age-related degeneration in the heart.

Turmeric battles hard-to-treat autoimmune conditions

Because turmeric is such a potent antioxidant and anti-inflammatory, numerous studies have been conducted to see whether it could be effective in reducing the severity of inflammation-based autoimmune diseases.

In autoimmune diseases, the body is attacked by its own immune system. These diseases are still poorly understood, and most of them have no known cause or cure. Common autoimmune diseases include type 1 diabetes, inflammatory bowel disease (including ulcerative colitis and Crohn’s disease), rheumatoid arthritis, psoriasis, multiple sclerosis, myocarditis, thyroiditis, uveitis, systemic lupus erythromatosis and myasthenia. An estimated 5 percent of the world’s population suffers from an autoimmune disease.

According to a research review published in the journal Advances in Experimental Medicine and Biology in 2007, curcumin has been shown to reduce the symptoms of inflammatory bowel disease, multiple sclerosis, rheumatoid arthritis and psoriasis in humans or animals. As expected, symptomatic relief comes, at least in part, from the regulation of inflammation pathways.

It should be noted that the body absorbs curcumin most effectively from turmeric root, rather than from supplements. In addition, the maximum benefit to nutraceuticals typically comes when they are consumed at low doses over a long period of time. Nevertheless, at least one trial suggests that daily curcumin doses of up to 8 g might be safe for up to four months or longer.

7 Ways to Never Have a Heart Attack

  By: Ted Spiker

Gamblers, weathermen, and Dionne Warwick aren’t the only people who try to make a living predicting the future. Doctors do, too. Just as a gambler might gather stats like Sammy Sosa’s slugging percentage on Thursday games at home when the wind is less than 15 mph, a doctor gathers vital information to try to determine the odds on your health.

For years, physicians focused on basic measures, such as blood pressure, weight, and cholesterol. But recently, more and more studies have shown that there’s a new MVP (most valuable predictor) when it comes to forecasting heart disease. It’s a substance that sounds like a grunge-rock band: C-reactive protein (CRP).

Though it was discovered in 1930, only in the past several years has CRP been shown to be important. Doctors now know that CRP helps measure chronic inflammation and the overall health of your arteries. The higher your CRP level, the more at risk you may be for heart disease—even if your other indicators look normal.

“Half of all heart attacks and strokes in the United States each year occur among people with essentially normal cholesterol levels,” says Paul Ridker, M.D., a professor of medicine at Harvard medical school. “There’s more to heart disease than just lipids. In addition to the problem of cholesterol, there’s the problem of the immune system or the inflammation response.”

A heart attack occurs when plaque ruptures inside your blood vessels. But that rupturing hinges not just on how much plaque you have but also on the degree of inflammation, Dr. Ridker says. Your level of CRP—measured by a simple blood test—helps detect this condition so you can predict whether you’re in danger of cardiovascular disease and stroke. “You can be at quite a high risk of both despite having normal cholesterol,” Dr. Ridker says. “Even people with low cholesterol but high CRP are at high risk.”

Luckily, just as you can with cholesterol and body fat, you can take steps to shrink your CRP. “If you have your CRP measured in your 20s and 30s, you can prevent heart disease and strokes in your 50s and 60s,” Dr. Ridker says. Aside from drugs such as statins, lifestyle changes are the best way to whittle down your CRP and, more important, snuff the flames before they snuff you.

Pop a Multivitamin

A grande cappuccino isn’t the only thing you’d better slug down before you go to work. A study in the American Journal of Medicine showed that people who popped a multivitamin each morning for 6 months decreased their CRP by 0.7 milligrams per liter (mg/l). And a University of California at Berkeley study found that people who took 500 mg of vitamin C saw a 24 percent drop in CRP after just 2 months.

Arch Mainous, Ph.D., a professor of family medicine at the Medical University of South Carolina, says CRP levels are connected to the amount of stress caused by free radicals in your body. “Vitamins C and E decrease the oxidative stress,” he says.

Take 500 mg of a vitamin C supplement, or a multivitamin like GNC Men’s Mega Men, which contains one of the highest levels of vitamin C (300 mg) in a multi. Another way to swallow more C: cherries.

In a small study published in the Journal of Nutrition, people who ate two daily servings of cherries lowered their CRP by 16 percent.

Trust Your Greek Friends

Whether for your car, your uncle’s hair, or your arteries, the right kind of oil can make everything run smoothly. A recent study at the University of Athens in Greece found that people who most closely followed a Mediterranean diet—one rich in olive oil—had CRP numbers 20 percent lower than those of their less oily brethren.

“We believe olive oil helps turn off the gene that makes the pro-inflammatory molecules that attach to your arteries,” says Michael Roizen, M.D., a professor of medicine at SUNY Upstate Medical University and author of Real Age: Are You As Young As You Can Be?

Dr. Roizen suggests taking in 25 percent of your daily calories from monounsaturated fats, with an emphasis on olive oil as the source. One way to sneak it in: breakfast. Take a tablespoon of olive oil and mix in the spice of your choice—oregano if you like Italian food, red pepper if you like things spicy—then spread it on your toast, bagel, or English muffin. Or use it instead of butter when you’re cooking eggs.

Floss Like a Fiend

There’s a price to pay for a dirty mouth. One study in the Journal of Periodontology shows that the inflammatory effects of periodontal disease also cause inflammation of your arteries; signs of disease in multiple spots in your mouth can hike CRP by 14 percent.

“The bacteria that cause gum disease, we think, set up an immune reaction that attacks your arteries,” Dr. Roizen says. Floss daily, and make regular dentist appointments so hygienists can remove plaque.

Note: If you can’t stand flossing, at least rinse nightly with Listerine or a store-brand equivalent containing thymol, eucalyptol, menthol, and methyl salicylate. Recent research shows that this swish-and-spit protocol can be just as effective as flossing at fighting gum disease.

Build a Salmon Burger

Yet another bullet point to add to fish oil’s already impressive resume: “Lowers CRP.”

In a new Harvard study, people who consumed the most omega-3 fatty acids (1.6 grams per day) had 29 percent lower CRP readings than those who ate the least. “Omega-3 fatty acids may decrease hydrogen peroxide, which plays an important role in the inflammatory process,” says study author Esther Lopez-Garcia, Ph.D.

Good sources of omega-3s include flaxseed, walnuts, sardines, tuna, and, of course, salmon. And though wild salmon is tops for taste, the canned kind is better at lowering CRP. “Canned salmon is packed in vegetable oils that also contain omega-3s,” says Lopez-Garcia.

Here’s how to get your health on a roll: Drain the liquid from a 6-ounce can of pink salmon and dump the fish into a bowl. Mix well with one Egglands Best egg (fortified with 150 mg omega-3s), 1/4 cup of diced red onion, and a tablespoon of bread crumbs. Form into two patties and dredge in additional bread crumbs. Bake at 350 degrees for about 20 minutes. Slip the patties inside whole-wheat buns.

Cut the Fuel Supply

We already know what kind of damage fat can do—both to your body and to subway turnstiles. Losing that fat by cutting calories is an important way to put the squeeze on CRP.

In a Wake Forest University study, those who cut calories and lost weight reduced their CRP by 6 percent over an 18-month period, says study author Barbara Nicklas, Ph.D. She speculates that the body reduces inflammation because it’s not being stoked with excess calories.

Nicklas says that firing up your metabolism with interval training can also help decrease inflammation.

Try this track workout: After warming up, run a quarter of the way around a track (about 100 meters) at close to sprint pace. Rest until you recover, then run 200 meters as fast as you can at a near-sprint pace. Rest, then do 300 meters. Rest, then do 400 meters. Now come back down the ladder—300 meters then rest, 200 then rest, and finally 100 meters.

Eat Fiber, Fiber, and More Fiber!

Leave the Froot Loops for the kids and reach for the All-Bran. In a study published in the Journal of Nutrition, the odds of having high levels of CRP dropped by 40 percent for those people who had the most fiber during the day.

Possible reasons include fiber’s impact on insulin and its ability to bring down cholesterol and blood pressure. “It’s also possible that fiber may have an independent effect through other processes,” says study author Umed Ajani, M.D.

Whatever the reason, consume your recommended 20-plus grams (g) of fiber with the ABC method: Each day, eat an apple (3 g), two slices of whole-grain bread (4 g), and a large bowl of fiber-rich cereal such as All-Bran (13 g).

Go Out with the Guys

Catch Monday Night Football together and the social interaction may help you beat another CRP booster: depression.

According to a Johns Hopkins University study, men who were depressed had a 64 percent chance of having higher levels of CRP, and a new Duke study showed that people with moderate symptoms of depression had two times higher CRP numbers than their light-hearted counterparts. The causes aren’t clear, but depression may boost norepinephrine, a stress hormone that triggers chronic inflammation.

Bonus: Down a beer with the boys and you may lower your CRP even further, according to a study published in the journal Atherosclerosis.

Fit heart can slow brain ageing, US researchers say

Heart and brain health appear to go hand in hand
Keeping your heart fit and strong can slow down the ageing of your brain, US researchers say.
A Boston University team found healthy people with sluggish hearts that pumped out less blood had “older” brains on scans than others.
Out of the 1,500 people studied, the team observed that the brain shrinks as it ages.
A poor cardiac output aged the brain by nearly two years on average, Circulation journal says.
The link was seen in younger people in their 30s who did not have heart disease, as well as elderly people who did.
“Start Quote
It is too early to dole out health advice based on this one finding but it does suggest that heart and brain health go hand in hand”
Dr Angela JeffersonLead researcher
Lead researcher Dr Angela Jefferson said: “These participants are not sick people. A very small number have heart disease. The observation that nearly a third of the entire sample has low cardiac index and that lower cardiac index is related to smaller brain volume is concerning and requires further study.”
The participants with smaller brain volumes on magnetic resonance imaging did not show obvious clinical signs of reduced brain function.
But the researchers say the shrinkage may be an early sign that something is wrong.
More severe shrinkage or atrophy occurs with dementia.
Dr Jefferson said there were several theories for why reduced cardiac index – how much blood the heart pumps out relative to body size – might affect brain health.
For example, a lower volume of blood pumping from the heart might reduce flow to the brain, providing less oxygen and fewer nutrients needed for brain cells.
“It is too early to dole out health advice based on this one finding but it does suggest that heart and brain health go hand in hand,” she said.
Experts say a person’s cardiac index is fairly static – meaning it would be difficult to change it if it were low, without doing pretty intensive exercise training.
Dr Clinton Wright, a brain and memory expert from the University of Miami, said: “Whether lower cardiac index leads to reduced brain volumes and accelerates neurodegeneration on an eventual path to dementia is not yet clear.
“To address the health needs of our ageing population, a better understanding of the links between cardiovascular disease and brain structure and function will be required.”
The Boston School of Medicine team will now continue to study the individuals in the trial to see if and how the brain changes affect memory and cognitive abilities over time.
