Ginger Root for Migraines

Ginger Root for Migraines.jpeg

Many successful herbal treatments start like this: Some doctor learns that some plant has been used in some ancient medical tradition, like ginger for headaches. Well, the physician has patients with headaches and so tries advising one with migraines to give it a try since it's just some safe, common spice. At the first sign of a migraine coming on, the patient mixed a quarter teaspoon of powdered ginger in some water, drank it down, and poof! Within a half-hour, the migraine went away. It worked every time for them with no side effects. That's what's called a case report.

In my video, Ginger for Migraines, I show the remarkable case report, but case reports are really just glorified anecdotes. Case reports have played an important role in the history of medicine, though. AIDS was first discovered as a series of case reports. Some young guy walks into a clinic in Los Angeles with a bad case of thrush, and the rest is history. Reports of an unusual side effect of a failed chest pain drug led to the billion-dollar blockbuster, Viagra. Case reports may represent the weakest level of evidence, but they are often the first line of evidence, where everything starts. The ginger and migraine report isn't helpful in itself, but it can inspire researchers to put the treatment to the test.

The problem is, who's going to fund it? The market for migraine drugs is worth billions of dollars. A quarter teaspoon of powdered ginger costs about a penny. Who would fund a study pitting ginger versus the leading migraine drug?

No one... that is, until now. A double-blinded, randomized, controlled, clinical trial compared the efficacy of ginger to sumatriptan, also known as Imitrex, one of the top-selling billion-dollar drugs in the world in the treatment of migraine headaches. Researchers tried using only one-eighth of a teaspoon of powdered ginger versus a good dose of the drug.

They both worked just as well and just as fast.

Most patients started out in moderate or severe pain but, after taking the ginger or the drug, ended up in mild pain or completely pain-free. The same proportion of migraine sufferers reported satisfaction with the results either way. As far as I'm concerned, ginger won--not only because it's a few billion dollars cheaper than the drug, but because there were significantly fewer side effects in the ginger group. People taking sumatriptan reported dizziness, a sedative effect, vertigo, and heartburn. The only thing reported for ginger was an upset tummy in about 1 out of 25 people. (As a note of caution, taking a whole tablespoon of ginger powder at one time on an empty stomach could irritate anyone's stomach.)

An eighth of a teaspoon of ginger is not only up to 3000-times cheaper than the drug, but you're also less likely to end up as a case report yourself of someone who had a heart attack or died after taking the drug--tragedies that have occurred due to sumatriptan.

These are my favorite kinds of posts to do because I can offer something that is immediately practical, cheap, safe, and effective to reduce suffering. If this kind of information helps you or someone you love, I hope you'll consider making a tax-deductible donation to support the nonprofit organization that runs NutritionFacts.org. We have a growing staff and server costs to cover, and any help you could give would be much appreciated (and there are perks!).

Best Food for MGUS to Prevent Multiple Myeloma

Best Food for MGUS to Prevent Multiple Myeloma.jpeg

Multiple myeloma is one of our most dreaded cancers. It's a cancer of our antibody-producing plasma cells, and is considered one of our most intractable blood diseases. The precursor disease is called monoclonal gammopathy of undetermined significance (MGUS). When it was named, it's significance was undetermined, but now we know that multiple myeloma is almost always preceded by MGUS. This makes MGUS one of the most common premalignant disorders, with a prevalence of about 3% in the older white general population, and about 2 to 3 times that in African-American populations.

MGUS itself is asymptomatic, you don't even know you have it until your doctor finds it incidentally doing routine bloodwork. But should it progress to multiple myeloma, you only have about four years to live. So we need to find ways to treat MGUS early, before it turns into cancer. Unfortunately, no such treatment exists. Rather, patients are just placed in a kind of holding pattern with frequent check-ups. If all we're going to do is watch and wait, researchers figured to might as well try some dietary changes.

One such dietary change is adding curcumin, the yellow pigment in the spice turmeric. Why curcumin? It's relatively safe, considering that it has been consumed as a dietary spice for centuries. And it kills multiple myeloma cells. In my video Turmeric Curcumin, MGUS, & Multiple Myeloma, you can see the unimpeded growth of four different cell lines of multiple myeloma. We start out with about 5000 cancer cells at the beginning of the week, which then that doubles, triples, and quadruples in a matter of days. If we add a little bit of curcumin, growth is stunted. If we add a lot of curcumin, growth is stopped. This was in a petri dish, but it is exciting enough to justify trying curcumin in a clinical trial. And six years later, researchers did.

We can measure the progression of the disease by the rise in blood levels of paraprotein, which is what's made by MGUS and myeloma cells. About 1 in 3 of the patients responded to the curcumin with dropping paraprotein levels, whereas there were no responses in the placebo group. These positive findings prompted researchers to commence a double-blind, randomized, controlled trial. The same kind of positive biomarker response was seen in both MGUS patients as well as those with so-called "smoldering" multiple myeloma, an early stage of the cancer. These findings suggest that curcumin might have the potential to slow the disease process in patients, delaying or preventing the progression of MGUS to multiple myeloma. However, we won't know for sure until longer larger studies are done.

The best way to deal with multiple myeloma is to not get it in the first place. In my 2010 video Meat & Multiple Myeloma, I profiled a study suggesting that vegetarians have just a quarter the risk of multiple myeloma compared to meat-eaters. Even just working with chicken meat may double one's risk of multiple myeloma, the thinking being that cancers like leukemias, lymphomas, and myelomas may be induced by so-called zoonotic (animal-to-human) cancer-causing viruses found in both cattle and chickens. Beef, however, was not associated with multiple myeloma.

There are, however, some vegetarian foods we may want to avoid. Harvard researchers reported a controversial link between diet soda and multiple myeloma, implicating aspartame. Studies suggest french fries and potato chips should not be the way we get our vegetables, nor should we probably pickle them. While the intake of shallots, garlic, soy foods, and green tea was significantly associated with a reduced risk of multiple myeloma, intake of pickled vegetables three times a week or more was associated with increased risk.

For dietary links to other blood cancers, see EPIC Findings on Lymphoma.

The turmeric story just never seems to end. I recommend a quarter teaspoon a day:

Why Some Like Cilantro and Others Hate It

The Cilantro Gene.jpg

One sign of changing U.S. demographics is that salsa has replaced ketchup as America's #1 table condiment. One of the popular salsa ingredients is cilantro, described as one of the "most polarizing and divisive food ingredients known." Some people love it; some people hate it. What's interesting is that the lovers and the haters appear to experience the taste differently. Individuals who like cilantro may describe it as "fresh, fragrant or citrusy, whereas those who dislike cilantro report that it tastes like soap, mold, dirt, or bugs." I don't know how people know what bugs taste like, but rarely are polarizing opinions about flavors so extreme. Maybe it's genetic.

Different ethnic groups do seem to have different rates of cilantro dislike, with Ashkenazi Jews scoring highest on the cilantro hate-o-meter (see The Cilantro Gene). Another clue came from twin studies, that show that identical twins tend to share cilantro preferences, whereas regular fraternal twins do not have such a strong correlation. Our genetic code is so big, though, containing about three billion letters, that to find some cilantro gene you'd have to analyze the DNA of like 10,000 people, and obviously genetic researchers have better things to do...or maybe not.

Researchers performed a genome-wide association study among 14,000 participants who reported whether cilantro tasted soapy, with replication in a distinct set of 11,000 people who declared whether they liked cilantro or not. And lo and behold they found a spot on chromosome 11 that seemed to be a match. What's there? A gene called OR6A2 that enables us to smell certain chemicals like E-(2)-Decenal, a primary constituent of cilantro and also...the defensive secretions of stink bugs. So maybe cilantro does taste like bugs! But, cilantro lovers may be genetic mutants that have an inability to smell the unpleasant compound.

That may actually be an advantage, though, since cilantro is healthy stuff. In fact, that's the justification to do these kinds of studies: to see why some people don't like the taste of healthy foods.

Are the cilantro haters really missing out on much, though? Mother nature has been described as the "oldest and most comprehensive pharmacy of all time," and cilantro--called coriander around most of the world--is one of nature's oldest herbal prescriptions, credited with anti-microbial, anti-oxidant, anti-diabetic, anti-anxiety, and anti-epilepsy properties. However, these are all from preclinical studies, meaning studies done on cells in a test tube or lab animals. Studies like the "Anti-Despair Activity of Cilantro..." in which researchers placed animals in a "despair apparatus" (you don't want to know).

Finally, though, there was a human study, on the anti-arthritis potential of cilantro. There was an earlier study performed in Germany of a lotion made out of cilantro seeds showing it could decrease the redness of a sunburn, demonstrating it had some anti-inflammatory effects )though not as much as an over-the-counter steroid, hydrocortisone, or prescription strength steroid cream). If the cilantro plant is anti-inflammatory, why nto give it to people with osteoarthritis and see if it helps? Researchers gave about 20 sprigs of cilantro daily for two months, and reported a significant drop in ESR--a nonspecific indicator of inflammation--in the cilantro group. How did the patients do clinically, though? The study didn't say, but it did report a rather remarkable 50% drop in uric acid levels, suggesting that huge amounts of cilantro may be useful for those suffering from gout.


The cilantro lovers/haters factoid reminds me of the video Pretty in Pee-nk about the phenomenon of "beeturia," pink urine after beet consumption seen in some people.

For those that don't mind the taste of bugs, I have some nutritional info in Good Grub: The Healthiest Meat and Bug Appétit: Barriers to Entomophagy.

As an Ashkenazim myself, I'm excited to have narrowly escaped a cilantro-less existence!

How May Eating Plants Help Prevent Alzheimer’s Disease?

NF-Oct27 Preventing Alzheimers Disease with Plants.jpeg

Intake of saturated fats and added sugars, two of the primary components of a modern Western diet, is linked with the development of Alzheimer's disease. There has been a global shift in dietary composition, from traditional diets high in starches and fiber, to what has been termed the Western diet, high in fat and sugar, low in whole, plant foods. What's so great about fruits and vegetables?

Plant-derived foods contain thousands of compounds with antioxidant properties, some of which can traverse the blood-brain barrier and may have neuroprotective effects by assisting with antioxidant defense. There's this concept of "brain rust," that neurodegenerative diseases arise from excess oxidative stress. But Nature has gifted humankind with a plethora of plants--fruits, vegetables, and nuts, and the diverse array of bioactive nutrients present in these natural products may play a pivotal role in prevention and one day, perhaps, even the cure of various neurodegenerative diseases, such as Alzheimer's disease.

Accumulated evidence suggests that naturally occurring plant compounds may potentially hinder neurodegeneration, and even improve memory and cognitive function, as I've shared in my videos Preventing Alzheimer's Disease with Plants and How to Slow Brain Aging By Two Years) and treating Alzheimer's with spices such as saffron or turmeric (See Saffron for the Treatment of Alzheimer's and Treating Alzheimer's with Turmeric).

Vegetables may be particularly protective, in part because of certain compounds we eat that concentrate in the brain, found in dark green leafy vegetables, the consumption of which are associated with lower rates of age-related cognitive decline.

Yet when you look at systemic reviews on what we can do to prevent cognitive decline, you'll see conclusions like this: "The current literature does not provide adequate evidence to make recommendations for interventions." The same is said for Alzheimer's, "Currently, insufficient evidence exists to draw firm conclusions on the association of any modifiable factors with risk of Alzheimer's disease." Doctors cite the lack of randomized controlled trials (RCTs) as the basis for their conclusions. RCTs are the gold standard used to test new medicines. This is where researchers randomize people into two groups, half get the drug and half don't, to control for confounding factors. The highest level of evidence is necessary because drugs may kill a hundred thousand Americans every year - not medication errors or illicit drugs, just regular, FDA-approved prescription drugs, making medication alone the sixth leading cause of death in the United States. So, you better make absolutely sure the benefits of new drugs outweigh the often life-threatening risks.

But we're talking about diet and exercise--the side effects are all good, so we don't need the same level of rigorous evidence to prescribe them.

A "modest proposal" was published recently in the Journal of Alzheimer's Disease, an editorial calling for a longitudinal study of dementia prevention. They agreed that definitive evidence for the effectiveness of dementia prevention methods was lacking, so we need large-scaled randomized trials. They suggested we start with 10,000 healthy volunteers in their 20's and split them into five groups. There's evidence, for example, that traumatic brain injury is a risk factor for Alzheimer's, because people with head injuries appear more likely to get the disease, but it's never been put to the test. So, they say, let's take two thousand people and beat half of them in the head with baseball bats, and the other half we'll use Styrofoam bats as a control. Afterall, until we have randomized controls, how can't physicians recommend patients not get hit in the head? They go further saying we should probably chain a thousand people to a treadmill for 40 years, and a thousand people to a couch before recommending exercise. A thousand will be forced to do crossword puzzles; another thousand forced to watch Jerry Springer reruns, lots of meat and dairy or not prescribed for another group for the next 40 years, and we can hook a thousand folks on four packs a day just to be sure.

We help our patients to quit smoking despite the fact that there's not a single randomized controlled trial where they held people down and piped smoke into their lungs for a few decades. It is time to realize that the ultimate study in regard to lifestyle and cognitive health cannot be done. Yet the absence of definitive evidence should not restrict physicians from making reasonable recommendations based on the evidence that is available.

I've discussed how drug-centric approaches to evidence-based medicine may neglect some of the most convincing data: Evidence-Based Medicine or Evidence-Biased?

To see how and why I built NutritionFacts.org on evidence-based principles, see my recent introductory videos:

How Turmeric Can Help Combat the Effects of Sitting

NF-Oct25 Turmeric vs Exercise for Artery Function.jpeg

The average American spends most of their waking life sitting down, which is associated with an increased risk of death even among people who go to the gym after work and exercise regularly. Doing lots of sitting may double our risk of diabetes and heart disease while significantly shortening our lifespan, even at the highest levels of physical activity. Sitting six or more hours a day may increase mortality rates even among those running or swimming an hour a day, every day, seven days a week. Why though? I examine this in Turmeric Cucumin vs. Exercise for Artery Function.

One factor may be endothelial dysfunction, the inability of the inner lining of our blood vessels to relax our arteries normally in response to blood flow. Just like our muscles atrophy if we don't use them, when it comes to arterial function, it's 'use it or lose it' as well. Increased blood flow promotes a healthy endothelium. The cells lining our arteries can actually sense the sheer force of the blood flowing past. That flow is what maintains the stability and integrity of the inner lining of our arteries. Without that constant tugging flow, it may help set us up for heart disease.

We actually have some data now suggesting that treadmill desks may improve the health of office workers without affecting work performance, and walking may be preferable to standing in terms of clearing fat from our bloodstream, which can play a role in endothelial dysfunction.

What if our office can't accommodate a standing or walking desk? Within an hour of sitting, blood starts pooling and blood flow starts to stagnate, so the more we can take breaks the better. Preliminary evidence from observational and interventional studies suggests that regular interruptions in sitting time can be beneficial. And it doesn't have to be long. Breaks could be as short as one minute and not necessarily entail exercise, just something like taking out the trash during commercials may be beneficial.

I've talked about the effects of different diets on endothelial function (See Eggs and Arterial Function, Walnuts and Arterial Function, Vinegar and Artery Function, and Dark Chocolate and Artery Function) and how certain foods in particular--nuts and green tea--are beneficial for endothelial health. Recently, researchers tried out curcumin, the yellow pigment in the spice turmeric.

They showed that regular ingestion of curcumin or up to an hour a day of aerobic exercise training significantly improved endothelial function. And the magnitude of improvement in endothelial function was the same. So does that mean we can just be a couch potato as long as we eat curried potatoes? No, the combination of curcumin and exercise appears to work even better than either alone.

I'm on my third treadmill desk motor, after burning out two. The 2nd one lasted 7,000 miles, though. Could have walked back and forth across the country! I do about 17 miles a day. More on treadmill desks in Standing Up for Your Health.

Amazing how much beneficial just simple walking can be: Longer Life Within Walking Distance

Treating Pancreatic Cancer with Turmeric Curcumin

NF-May26 Turmeric Curcumin and Pancreatic Cancer.jpeg

Pancreatic cancer is among the most aggressive forms of human cancer, characterized by a very high mortality rate. It represents the fourth leading cause of cancer death in United States, killing 32,000 people annually. With a five-year survival rate of only three percent and a median survival rate of less than six months, pancreatic cancer carries one of the poorest prognoses. The diagnosis of pancreatic cancer is one of the worst things a doctor ever has to tell a patient. The only FDA-approved therapies for it, Gemcitabine and Erlotinib, produce objective responses in less than ten percent of patients, while causing severe side-effects in the majority. There is a desperate need for new options.

Clinical research to test new treatments is split into phases. Phase I trials are just to make sure the treatment is safe, to see how much you can give before it becomes toxic. Curcumin, the natural yellow pigment in the spice turmeric has passed a number of those. In fact, there was so little toxicity, the dosing appeared limited only by the number of pills patients were willing to swallow.

Phase II trials are conducted to see if the drug actually has an effect. Curcumin did, in 2 of the 21 patients that were evaluated. One patient had a 73 percent tumor reduction, but the effect was short-lived. One lesion remained small, but a curcumin-resistant tumor clone emerged. The other patient, who had a stable disease for over 18 months, showed slow improvement over a year. The only time that patient's cancer markers bumped up was during a brief three-week stint where the curcumin was stopped.

So curcumin does seem to help some patients with pancreatic cancer, and most importantly, there appears to be little downside. No curcumin-related toxic effects were observed in up to doses of eight grams per day. What happens after eight grams? We don't know because no one was willing to take that many pills. The patients were willing to go on one of the nastiest chemotherapy regimens on the planet, but didn't want to be inconvenienced with swallowing a lot of capsules.

The only surefire way to beat pancreatic cancer is to prevent it in the first place. In 2010 I profiled a study conducted by the National Institutes of Health, the largest such study in history, which found that dietary fat of animal origin was associated with increased pancreatic cancer risk.

Which animal fat is the worst? The second largest study (highlighted in my video: Turmeric Curcumin and Pancreatic Cancer) has since chimed in to help answer that question. Researchers found that poultry was the worst, with 72 percent increased risk of pancreatic cancer associated with every 50 grams of daily poultry consumption. Fifty grams is just about a quarter of a chicken breast. The reason white meat came out worse than red may be because of the cooked meat carcinogens in chicken, the heterocyclic amines that build up in grilled and baked chicken. These mutagenic chemicals have been associated with a doubling of pancreatic cancer risk (See Estrogenic Cooked Meat Carcinogens).

Meat has been associated with significantly increased risk, whereas fake meat is associated with significantly less risk. Those who eat plant-based meats like veggie burgers or veggie dogs three or more times a week had less than half the risk of fatal pancreatic cancer. Legumes and dried fruit appear to be similarly protective.

My grandfather died of pancreatic cancer. By the time the first symptom arose, a dull ache in his gut, it was too late. That's why we need to work on preventing it.

I previously touched on pancreatic cancer prevention in Poultry Exposure Tied to Liver and Pancreatic Cancer and attempts at pancreatic cancer treatment in Gerson Therapy for Cancer and Gerson-style Therapy vs. Chemotherapy.

Can Turmeric Help with Alzheimer’s?

NF-Apr14 Treating Alzheimer's with Turmeric.jpeg

The spice turmeric may help prevent Alzheimer's disease (See Preventing Alzheimer's with Turmeric), but what about treating Alzheimer's disease with turmeric? An exciting case series was published in 2012 (highlighted in my video, Treating Alzheimer's with Turmeric): three Alzheimer's patients were treated with turmeric, and their symptoms improved.

In case number one, an 83-year-old woman started losing her memory and feeling disoriented. She started having problems taking care of herself, wandering aimlessly and became incontinent. After taking a teaspoon of turmeric per day however, her agitation, apathy, anxiety and irritability were relieved and she had less accidents. Furthermore, she began to laugh again, sing again, and knit again. After taking turmeric for more than a year, she came to recognize her family and now lives a peaceful life without a significant behavioral or psychological symptom of dementia.

Case number two was similar, but with the additional symptoms of hallucinations, delusions and depression, which were relieved by turmeric. She began to recognize her family again and now lives in a peacefully serene manner. And the third case, similar as well, included an improvement in cognition.

Researchers concluded that this was the first demonstration of turmeric as an effective and safe "drug" for the treatment of the behavioral and psychological symptoms of dementia in Alzheimer's patients. They call it a drug, but it's just a spice you can walk into any grocery store and buy for a few bucks. They were giving people like a teaspoon a day, which comes out to be about 15 cents.

Two trials using curcumin supplements rather than turmeric, however, failed to show a benefit. Curcumin is just one of hundreds of phytochemicals found in turmeric. Concentrated into pill form at up to 40 times the dose, no evidence of efficacy was found. Why didn't they get the same dramatic results we saw in the three case reports? Well, those three cases may have been total flukes, but on the other hand, turmeric, the whole food, may be greater than the sum of its parts.

There is a long list of compounds that have been isolated from turmeric, and it's possible that each component plays a distinct role in making it useful against Alzheimer's disease. Hence, researchers suggested that a mixture of compounds might better represent turmeric in its medicinal value better than curcumin alone. But why concoct some artificial mixture when Mother Nature already did it for us with turmeric? Because you can't patent the spice. And if you can't patent it, how are you going to charge more than 15 cents?

I've previously addressed the thorny issue of patenting natural plant remedies in my video: Plants as Intellectual Property - Patently Wrong?

The whole-greater-than-the-sum-of-its-parts theme is one that comes up over and over:

What else might the cheap, easily available spice turmeric do? It may help fight arthritis (Turmeric Curcumin and Rheumatoid Arthritis and Turmeric Curcumin and Osteoarthritis) and cancer:

But it's not for everyone: Who Shouldn't Consume Curcumin or Turmeric?

Might Turmeric Help Prevent Alzheimer’s?

NF-Apr12 Preventing Alzheimer's with Turmeric.jpeg

There are plenty of anti-inflammatory drugs out there that may reduce the risk of Alzheimer's disease, but stomach, liver, and kidney toxicity precludes their widespread use. So maybe using an anti-inflammatory food like the spice, turmeric, found in curry powder, could offer the benefits without the risks? Before even considering putting it to the test, though, one might ask, "Well, do populations that eat a lot of turmeric have a lower prevalence of dementia?" And indeed, those living in rural India who do just that may actually have the lowest reported prevalence of dementia and Alzheimer's.

In rural Pennsylvania, the incidence rate of Alzheimer's disease among seniors is 19/1000. Nineteen people in a thousand over age 65 develop Alzheimer's every year in rural Pennsylvania. In rural India, using the same diagnostic criteria, that same rate is three, confirming they have among the lowest reported Alzheimer's rates in the world.

Although the lower prevalence of Alzheimer's in India is generally attributed to the turmeric consumption as a part of curry, and it is assumed that people who use turmeric regularly have a lower incidence of the disease, but let's not just assume. As highlighted in my video, Preventing Alzheimer's with Turmeric, a thousand people were tested, and those who consumed curry at least occasionally did better on simple cognitive tests than those who didn't. Those that ate curry often also had only about half the odds of showing cognitive impairment, after adjusting for a wide variety of potential confounding factors. This suggests that curry consumption may indeed be associated with better cognitive performance.

Of course it probably matters what's being curried--are we talking chicken masala, or chana masala, with chickpeas instead of chicks? It may be no coincidence that the country with among the lowest rates of Alzheimer's also has among the lowest rates of meat consumption, with a significant percentage of Indians eating meat-free and egg-free diets.

Studies have suggested for nearly 20 years now that those who eat meat--red meat or white meat--appear between two to three times more likely to become demented compared to vegetarians. And the longer one eats meat-free, the lower the associated risk of dementia, whether or not you like curry.

There's another spice that may be useful for brain health. See my video Saffron for the Treatment of Alzheimer's. What about coconut oil? See Does Coconut Oil Cure Alzheimer's? In terms of preventing cognitive decline in the first place, check out my video How to Slow Brain Aging By Two Years.
